What information does the Kardashev scale provide us?

Oleksandr Burlaka

When it comes to how much more advanced extraterrestrial civilizations may be than us, the Kardashev scale is often mentioned. It suggests the possibility of civilizations that can control the energy of entire galaxies. But does that mean they are truly advanced?

Aliens

The science of extraterrestrial civilizations is still in its infancy. This is not surprising, given that no representative of such civilizations has ever been seen or heard. However, several concepts have already been developed in this field, which are widely used both in research and in popular presentations of the state of affairs in this area.

One of them is the Kardashev scale, which describes how advanced civilizations we may encounter. They are divided into three types based on the total power of all their activities (machines, power plants, etc.). Type I – those that operate with all the energy of their own planet, 1.74·10¹⁷ W. Type II – those that operate with energy comparable to a star (3.828·10²⁶ W for the Sun). Type III – those that operate with energies comparable to an entire galaxy, 8·10³⁶ W.

As you can easily see, the difference between types I and II is nine orders of magnitude, or approximately one billion times, and between types II and III it is ten orders of magnitude, or 10 billion times. Earth’s civilization does not even reach the first type, and this always shocks people who see this picture for the first time.

The Kardashev scale is often presented as something that really helps us understand how far ahead of us aliens whose civilizations existed millions or even billions of years ago might be. But is this really the case? Let’s figure it out together.

Signal transmission over distance

The main thing to know about where the scale of civilization development came from and why it is the way we know it is that Nikolai Kardashev, its author, was an astrophysicist. He was not a historian, a robotics expert, or a biologist, but rather a person who was accustomed to looking at distant lights in the sky and constructing theories about what they were.

The scale itself was presented in the report “Transmission of information by extraterrestrial civilizations,” presented at the 1964 Byurakan Conference, which took place at the observatory of the same name in Armenia. On the one hand, this meant that the concept very quickly became known to all leading world experts in the study of extraterrestrial life. On the other hand, it was a report read by an astrophysicist for astrophysicists.

Kardashev began by asking himself at what distance an extraterrestrial civilization could send a signal to everyone else in such a way that a meaningful response could be heard, and what would be required to do so. To do this, he uses the Shannon-Hartley theorem, which links the speed of information transmission to the signal-to-noise ratio. In simpler terms, it describes how many bits can be transmitted per second so that most of them are not lost on the way to the recipient.

Kardashev showed that the noise level in a signal traveling through millions of light-years of space is related to the temperature of background radiation. And it depends on the frequency at which the transmission is carried out. That is why the lowest noise level and the highest channel capacity are possible in the centimeter and decimeter ranges. That is, approximately where radio, television, and Wi-Fi operate, and slightly into the operating range of microwave ovens. It is no coincidence that the latter have played a cruel joke on alien hunters at least once.

In fact, it was this part of Kardashev’s Burakan report that had the greatest impact on the search for extraterrestrial civilizations, as it determined the frequencies at which it is best to send signals in space, regardless of biological origin and way of thinking. The most popular wavelength turned out to be 21 cm, but scientists have not yet heard anything about it.

The original Kardashev scale

However, Kardashev did not stop there and moved on from the question of frequency to the required transmitter power. He did not delve into the technical details of its design, simply setting its upper limit as all the energy available to civilization – almost the only figure on Earth that can be estimated without speculation, not only in absolute terms, but also in terms of annual growth.

During Kardashev’s time, these figures were 4×10¹² W and 3-4%, respectively. Currently, the total amount of energy used by humans is approximately 24×10¹³, which is still very little compared to the 1.74·10¹⁷ W that our planet receives from the Sun. As for the growth rate of Earth’s civilization, it has changed several times since the Byurakan Conference, but now, with Asia and Africa in a phase of active industrial growth, it is roughly the same as in the 1960s.

Be that as it may, Kardashev resorted to linear extrapolation of the figures available to him in his work and found that with steady growth in energy consumption, in 3,200 years, we will reach a level of energy consumption comparable to that of the Sun, and in 5,800 years, to that of the entire Milky Way. He called these states civilizations of types II and III and continued to consider them, because we were talking about truly cosmic distances.

Kardashev calculated that if a Type II civilization used all its energy to transmit a signal, useful information from it could be received at any point in our galaxy, even with the antennas that were available to humans in the second half of the 20th century.

At the same time, the maximum speed of information transfer, calculated using the Shannon theorem, is so high that aliens could transmit 10,000 medium-sized volumes of their scientific knowledge every 100 seconds. A Type III civilization could do the same for the entire visible part of the universe.

Where to look for aliens

Based on his own calculations, Kardashev even gives recommendations on how other astrophysicists should search for extraterrestrials. In his opinion, attention should be paid to very powerful but point sources of radiation, i.e., those whose area in the sky is tiny, but which emit an extremely large amount of energy.

Of course, the peak of this energy should fall precisely in the centimeter and decimeter ranges, meaning that it should be best visible using radio telescopes. In addition, the radiation must be polarized, meaning that its oscillations will occur in a single plane.

Kardashev himself was convinced that if not Type II, then Type III civilizations must exist in places where we can currently receive their signals. In particular, he considered the recently discovered CTA 102 source, which was extremely powerful and demonstrated variability, as a candidate for their transmitter.

Unfortunately, Kardashev underestimated the diversity of cosmic objects. We now know of many point sources that exhibit the behavior he described and are completely natural. In particular, STA 102 turned out to be an active galactic nucleus – a quasar that absorbs matter and changes brightness due to the unevenness of this process.

Will energy consumption really grow at a constant rate?

The Kardashev scale became popular thanks to American astrophysicist Carl Sagan. We also owe him the fact that it has changed from a purely rank-based scale, i.e., one with three marks, to a discrete scale, i.e., one that can accept fractional values.

This helped, in particular, to reconcile the numbers named by Kardashev with the amount of energy that the Earth receives from the Sun. It is now believed that humanity has a rating of 0.73 on the energy consumption scale. On the one hand, this makes the situation clearer, but on the other hand, it creates the impression that we are almost three-quarters of the way to reaching “one,” but in reality this is not the case, because the scale is logarithmic, meaning that the further you move, the more watts of power you need to add to the total treasury to add another hundredth. Therefore, in reality, all of human civilization still consumes a fraction of a percent of what the Earth receives from the Sun.

All this raises a much more important question: can our civilization’s energy consumption really reach the levels predicted by Kardashev? Observations of its growth rates over the 60 years since the astrophysicist made his report do not provide a clear answer to this question.

Now scientists, including renowned futurologist Michio Kaku, say that we are still 100-200 years away from Type I civilization, a millennium away from Type II, and hundreds of thousands of years away from Type III. For comparison, it is worth noting that only 10,000 years have passed since the beginning of the Neolithic Revolution, when agriculture began to play a greater role than hunting for people in the Middle East for the first time on Earth. So it turns out that our civilization is at the very beginning of an incredibly long journey.

Does development really mean an increase in power?

In fact, nothing is surprising in the fact that the path to Type III civilization can take hundreds of thousands or even millions of years. Kardashev himself suggested that for some time (thousands of years) the exchange of information would be one-sided, i.e., signals from Type III to Type I would reach their destination, but not vice versa. But eventually, all intelligent beings will get to the point where they can signal across the entire galaxy like a flashlight.

But this view is very one-sided, as Sagan himself pointed out. It is clear that Kardashev was an astrophysicist and, of all the models of extraterrestrial civilization behavior, he chose the one that would be easiest for him and his colleagues to detect. Because if aliens do not use most of their civilization’s power to signal to the entire universe that they are here and they are intelligent, then they remain invisible.

On the other hand, this view of the essence of civilization was very characteristic of the 1950s and 1960s in general. The Cold War was in full swing, and the US and the USSR were spending a lot of resources on demonstrating their power. After all, the Tsar Bomb was tested just three years before the Byurakan Conference.

But as time went on, the situation where an overdeveloped civilization spent most of its enormous power on sharing knowledge with other forms of life that were millions of years behind it seemed increasingly strange. This was because questions arose about the expediency of such activity.

Currently, Liu Cixin’s “dark forest” theory is considered one of the main antitheses to Kardashev’s idea and a possible explanation for the Fermi paradox. Civilizations sit silently because telling everyone around you that you exist and are intelligent means inviting attacks from all sides, because there are no friends in space, only competitors.

In fact, the dark forest theory is no better than Kardashev’s idea of civilizations gushing knowledge throughout the universe, because instead of peaceful megalomaniacal projects, they envisage spending most of a civilization’s power on military projects of no less absurd scale.

In reality, it is much simpler: neither the first nor the second civilizations are really necessary, because most of their members live their own lives and are not interested in other civilizations. Even large-scale projects such as generation ships, space stations for millions of inhabitants, or even terraforming planets require a lot of power, but significantly less than that needed to support Type II and Type III civilization transmitters.

Ultimately, even the very thesis of increasing machine power as the essence of civilization’s development can be questioned. The fact is that 60 years have passed since the Burakan Conference, and the Tsar Bomb remains the most powerful explosion ever created by humans. Moreover, the increase in the power of nuclear reactors essentially stopped several decades ago.

Instead of power, technological development specialists are increasingly talking about efficiency. And in most cases, this means “emitting less energy where it is not needed.” This is particularly evident in the example of information transmission systems. In the 1960s, the main devices used for this purpose were television and radio towers.

The principle behind their effectiveness was simple: raise the most powerful transmitter as high as possible. However, the advent of communication satellites made transmitters capable of sending signals further than 500 km unnecessary. Then, the emergence of various cable networks and automatic data routing systems revolutionized the field of information transmission. Modern cellular networks are generally based on transmitters with a range of several hundred meters. Why would you need more than that if data packets can simply be passed along like a baton?

Kardashev made his calculations for undirected signal radiation, and his followers have long since calculated that it is extremely ineffective at cosmic distances. Our terrestrial television is difficult to receive even near Alpha Centauri, and beyond that, it is lost in noise. But a directional signal can travel much greater distances with less transmitter power.

That is why space communications now increasingly rely on messages sent by a narrow beam, ideally a laser beam, and the problem is that it is practically impossible to intercept them accidentally in space. The argument that “aliens must communicate with each other somehow, and we will definitely hear it” falls away by itself.

Every day, on any city bus, dozens of people communicate with someone outside the bus, and other passengers have no idea what they are talking about. They only know that their neighbor, like themselves, is looking at a smartphone screen.

And in other industries, everything is moving in the same direction. A quadcopter has ridiculous power compared to a ballistic missile from the 1960s. At the same time, to the designers of that missile, it would have looked like a true creation of an extraterrestrial civilization. This is because it uses automatic control and feedback systems that were considered impossible just a couple of decades ago, especially on such a small machine.

All our experience over the past decades shows that power is not unnecessary. It is not the main thing. It is much better to improve the efficiency, reliability, and sophistication of our machines. In many ways, the fact that energy consumption continues to grow is explained by the fact that the world’s population continues to grow, and now even in countries that we are accustomed to calling the “third world,” people want to live according to energy consumption standards that even residents of developed countries in the 1960s would have considered luxurious.

No one knows how energy consumption will change when people across the planet satisfy their needs for the wonders of consumer electronics and electrical engineering, and when these technologies themselves become even more efficient. It is entirely possible that in the coming centuries we will not even reach Type I on the Kardashev scale.

It is quite possible that the future is not a stairway to heaven powered by clean energy, but a house built, at first glance, in the same way as houses were built centuries ago, but in fact filled with clever technology that surpasses a smartphone in functionality as much as a smartphone surpasses a rotary dial telephone.

Ultimately, Kardashev’s theory does not take into account even a more traditional scenario for the development of civilization: settlement within its own star system and beyond. In that case, intelligent beings could indeed have a total machine power comparable, if not to all solar radiation, then to the fraction that reaches Earth. But it would be scattered across a dozen star systems and mainly concentrated on ships flying between them. And there would be no question of any megastructures.

However, Kardashev himself should not be blamed for anything. He was a man of his time and, from the very beginning, did not claim to be anything more than a describer of the characteristics of civilization, the signals of which he could pick up as an astrophysicist. All other interpretations of his scale are later interpretations, and who is to blame for the fact that people continue to repeat them even though the experience of the development of Earth’s civilization increasingly diverges from his assumptions?

As NASA’s astronaut crew, engineers, and mission specialists prepare to make history with the forthcoming launch, here are five things you should know about Artemis II, its crew, and what its scientific missions will include while in orbit.

The Artemis II Mission

A focal point of the Artemis II mission involves the fact that this will be the first time NASA has launched a crew aboard its foundational deep space rocket, the SLS (Space Launch System), and the agency’s new Orion spacecraft.

While in orbit, the mission will provide NASA with the first real opportunity to test the operability of the spacecraft’s systems while having a space-bound crew on board. Not only that, but the mission’s trajectory will carry its astronaut crew farther than any human has traveled into space.

Fundamentally, Artemis II will offer a proving ground for NASA’s most state-of-the-art space exploration capabilities, while setting the pace for future missions that will travel to the lunar surface and, if all goes according to plan, establish a long-term presence on the Moon. This will not only support ongoing lunar science and exploration but will mark an important steppingstone on the path toward eventual crewed explorations of Mars. 

The Crew: First of “The Artemis Generation”  

NASA has selected a team of four astronauts for the Artemis II mission. The crew consists of Commander Reid Wiseman, a former Naval aviator and Chief of the Astronaut Office; Pilot Victor Glover, also a former Naval aviator who previously served as a pilot on the SpaceX Crew-1 mission; Mission Specialist Christina Koch, who currently holds the record for the longest single spaceflight by a woman; and Mission Specialist Jeremy Hansen, a Canadian Space Agency astronaut.

Notably, this foursome will be the first crew to carry NASA’s Space Launch System rocket and Orion spacecraft in a journey around the Moon, offering the first full systems test of the spacecraft’s capabilities in a full-scale space mission.

Astronaut Health Experiments

The Artemis II crew will perform a range of science experiments during their mission, many of which will focus on astronaut health to provide NASA with an unprecedented look at the impact of deep space travel on humans. Here’s a quick look at several of the health-related experiments the Artemis II crew will be conducting.

• ARCHeR: NASA’s Artemis Research for Crew Health and Readiness (ARCHeR) will focus on monitoring the crew’s sleep patterns, activity while on board, and overall well-being, which will inform future planning efforts to ensure optimal human health and performance in space.

• AVATAR: The A Virtual Astronaut Tissue Analog Response (AVATAR) study will comprise investigations into the effects of increased exposure to radiation and microgravity that the Artemis II crew will experience, monitored using organ-on-a-chip devices.
• Immune Biomarkers: During Artemis II, blood and saliva samples will also be monitored to study the impact of deep space travel on the immune system.
• Artemis II Standard Measures: Ongoing health information will be provided by each Artemis II astronaut, which will be stored in a data bank for use in future studies related to astronaut health.
• Radiation Studies: Additional monitoring of radiation levels within and outside the Orion capsule will allow NASA’s science team to characterize the deep space environment.

Lunar Science Studies

Since Artemis II marks the first time humans have journeyed to the Moon in more than 50 years, marking what NASA has dubbed “The Artemis Generation” of space exploration, the mission will collect large volumes of data related to lunar science.

During the crew’s passage by the far side of the Moon, the NASA astronauts will perform a three-hour analysis and image collection operation to photograph the Moon’s ancient lava flows, impact craters, and geological features.

Preparation for this portion of their mission included studies on Earth in moonlike environments like deserts and rocky landscapes, which help to inform them about many of the features they will document.

Other Artemis II Mission Objectives

• CubeSats: A range of other scientific studies will during the Artemis II mission, which will enable further studies that will be undertaken remotely by several of NASA’s international partners around the world, which include the transport of CubeSats aboard Artemis II.

“Space agencies from Germany, South Korea, Saudi Arabia, and Argentina will fly CubeSats aboard Artemis II,” NASA’s Artemis II website states. “The CubeSats, which have their own distinct objectives from NASA’s primary mission of sending four astronauts around the Moon, will be deployed in high Earth orbit.”

“In addition to the CubeSats, the German Aerospace Center (DLR) will conduct radiation research,” NASA’s statement reads.

• Payload Management: While the Artemis II astronauts are hard at work in deep space, back on Earth at the Payload and Mission Operations Division at NASA’s Marshall Space Flight Center in Huntsville, Alabama, NASA’s flight control team will be continuously monitoring the crew’s progress, while also managing several additional science priorities aboard the spacecraft from the facility’s Lunar Utilization Control Area.

• Real-Time Science Operations: Additionally, NASA will have a team specializing in the study of impact craters, lunar ice, tectonic activity, and volcanism on hand to provide real-time analysis and additional resources to the Artemis crew, all of which will be transmitted from the Science Evaluation Room located in the mission control facility at NASA’s Johnson Space Center in Houston, Texas.
• Space Weather Studies: Since Artemis II will be carrying humans far beyond Earth’s magnetosphere, the magnetic bubble that shields our planet from potentially harmful space weather emanating from the Sun, scientists at NASA, as well as its partners at NOAA, will be offering ongoing space weather forecasting to the Artemis II mission manager, flight director, and console operators throughout the duration of the mission.

Specifically, the NASA and NOAA teams will be watching for potential coronal mass ejections (CMEs) and solar flares, which have the potential to impact not only certain capabilities of the systems on board the spacecraft but also could potentially have a harmful impact on human health.

One Step Beyond

Once the official launch window for Artemis II has been determined, NASA will begin final preparations for launching the astronaut crew on its roughly 10-day mission from Launch Complex 39B at NASA’s Kennedy Space Center.

From there, the Artemis II crew will spend its first couple of days testing Orion’s systems, as well as undertaking a targeting demonstration while still close to Earth. From there, the team will begin their journey toward the Moon.

A burn from Orion’s European-built service module will propel the spacecraft into a four-day-long outbound trajectory, which will carry the Artemis II astronauts around the Moon’s far side on a figure-eight path that will extend more than 230,000 miles from Earth, and about 4,600 miles beyond the Moon at its farthest point.

Following the crew’s loop around the Moon, the mission will then enter a fuel-efficient free-return path that will rely on the gravitational properties of the Earth and the Moon to help bring Orion back home, which will eliminate any significant requirement for propulsion on the crew’s way home.

In the final phase of their return, the crew will endure a high-speed, high-temperature reentry not unlike past crewed missions have undergone before they splash down in the Pacific Ocean off the coast of San Diego. There, recovery teams comprised of NASA and Department of Defense personnel will retrieve the Artemis II astronauts.

In the days ahead, NASA will provide ongoing details as its teams continue preparations for the forthcoming launch, marking a major leap for human space exploration in the twenty-first century, and the initiation of the Artemis Generation of crewed deep space missions to study the Moon and beyond.

Out-of-control Chinese rocket smashes into the South Pacific Ocean - after Britain was put on red-alert over the potential of falling debris

• READ MORE: Step–by–step graphic reveals what will happen during Artemis II

By WILIAM HUNTER, SENIOR SCIENCE & TECHNOLOGY REPORTER

An out-of-control Chinese rocket has crashed into the Southern Pacific Ocean, after Britain readied the emergency alert system over fears of falling debris. 

Earlier today, the UK government asked mobile network providers to ensure the alert system is operational, in preparation for a potential impact.

However, the rocket has now safely landed in the ocean some 1,200 miles (2,000 km) southeast of New Zealand. 

The rocket, a Chinese Zhuque–3 launched in early December, crashed to Earth at 12:39 GMT, according to the US Space Force. 

With an estimated mass of 11 tonnes, the EU's Space Surveillance and Tracking (SST) agency had cautioned that ZQ–3 R/B was 'quite a sizeable object deserving careful monitoring.' 

While the vast majority of space debris which falls on Earth either burns up in the atmosphere or is never found, experts say we can be certain this rocket fell safely. 

Dr Marco Lanbroek, a debris tracking expert from the Delft University of Technology, says he 'strongly suspects' that the US Space Force observed the re-entry fireball using a space-based satellite. 

This puts an end to intense uncertainty over the rocket's potential landing site, after predictions suggested it could hit Northern Europe and the UK. 

The government asked mobile network operators to ensure the national emergency alert system is ready, as an out–of–control Chinese rocket (pictured) hurtles to Earth 

The rocket was launched by private space firm LandSpace from the Jiuquan Satellite Launch Center in China's Gansu Province on December 3, 2025.

The experimental rocket, dubbed ZQ–3 R/B, successfully reached orbit, but its reusable booster stage, modelled after the SpaceX Falcon 9, exploded during landing.

The upper stages and its 'dummy' cargo, in the form of a large metal tank, have been slowly slipping out of orbit.  

The rocket's shallow angle of re–entry had made it extremely difficult to predict exactly where any of the pieces might fall.

At the time, Professor Jonathan McDowell, an astronomer from the Harvard–Smithsonian Center for Astrophysics and expert on tracking space debris, told the Daily Mail: 'It will pass over the Inverness–Aberdeen area at 1200 UTC, so there's a small – a few per cent – chance it could re–enter there, otherwise it won't happen over the UK.'

It is not uncommon for pieces of rocket and satellite debris to fall to Earth, with debris passing over the UK about 70 times a month.

The overwhelming majority of the material is burned up upon re–entry due to friction with the atmosphere.

Despite earlier predictions that the rocket could land over Europe and the UK, observations now show that it has landed safely in the ocean  

The UK government asked mobile network providers to ensure the alert system is operational, in preparation for the possibility of an alert being issued 

In some cases, very large pieces of debris or fragments of heat–resistant materials, such as stainless steel or titanium, can make it to Earth.

However, these pieces generally disperse over the oceans or unpopulated areas.

The government also stresses that the 'readiness check' conducted by the mobile network providers is a routine practice that does not indicate that an alert will be issued.

A UK government spokesperson told the Daily Mail: 'It is extremely unlikely that any debris enters UK airspace.

'As you'd expect, we have well rehearsed plans for a variety of different risks including those related to space, that are tested routinely with partners.'

While there is almost no chance that this falling rocket will cause damage to life or property, researchers have warned that the risk of space debris is increasing.

The only recorded case of someone being hit by space debris occurred in 1997, when a woman was struck but not hurt by a 16–gram piece of a US–made Delta II rocket.

The rocket was launched by private space firm LandSpace from the Jiuquan Satellite Launch Center in China's Gansu Province on December 3, 2025. It has been slowly falling out of orbit since and has now crashed back to Earth

This is not the first time that a Chinese rocket has fallen to Earth. In 2024, fragments of a Long March 3B booster stage fell metres from homes in China's Guangxi province 

As the number of commercial launches increases, so too does the volume of 'uncontrolled' re–entries.

A recent study by scientists at the University of British Columbia suggested that there is now a 10 per cent chance that one or more people will be killed by space junk in the next decade.

Likewise, researchers have increasingly warned that falling debris could pose a threat to air travel, with a 26 per cent chance of something falling through some of the world's busiest airspace in any given year.

The actual chances of a plane being hit are currently very small, but a large piece of space junk could lead to widespread closures and travel chaos.

However, a 2020 study estimated that the risk of any given commercial flight being hit could rise to around one in 1,000 by 2030.

Nor is this the first time that a large Chinese–made rocket has unexpectedly crashed out of orbit.

In 2024, an almost complete Long March 3B booster stage fell over a village in a forested area of China's Guangxi Province, exploding in a dramatic fireball.

WHAT IS SPACE JUNK? MORE THAN 170 MILLION PIECES OF DEAD SATELLITES, SPENT ROCKETS AND FLAKES OF PAINT POSE 'THREAT' TO SPACE INDUSTRY

There are an estimated 170 million pieces of so-called 'space junk' - left behind after missions that can be as big as spent rocket stages or as small as paint flakes - in orbit alongside some US$700 billion (£555bn) of space infrastructure.

But only 27,000 are tracked, and with the fragments able to travel at speeds above 16,777 mph (27,000kmh), even tiny pieces could seriously damage or destroy satellites.

However, traditional gripping methods don't work in space, as suction cups do not function in a vacuum and temperatures are too cold for substances like tape and glue.

Grippers based around magnets are useless because most of the debris in orbit around Earth is not magnetic.

Around 500,000 pieces of human-made debris (artist's impression) currently orbit our planet, made up of disused satellites, bits of spacecraft and spent rockets

Most proposed solutions, including debris harpoons, either require or cause forceful interaction with the debris, which could push those objects in unintended, unpredictable directions.

Scientists point to two events that have badly worsened the problem of space junk.

The first was in February 2009, when an Iridium telecoms satellite and Kosmos-2251, a Russian military satellite, accidentally collided.

The second was in January 2007, when China tested an anti-satellite weapon on an old Fengyun weather satellite.

Experts also pointed to two sites that have become worryingly cluttered.

One is low Earth orbit which is used by satnav satellites, the ISS, China's manned missions and the Hubble telescope, among others.

The other is in geostationary orbit, and is used by communications, weather and surveillance satellites that must maintain a fixed position relative to Earth.

7 things Jesus actually taught about Hell

Few topics stir as much curiosity, fear, and misunderstanding as hell, with movies exaggerating it, social media joking about it, and some sermons weaponizing it.

Yet when you return to the Gospels themselves, Jesus speaks about hell in a far more serious, thoughtful, and compassionate way than most people expect. He never used the subject for shock value. He used it to call people toward reflection, responsibility, and hope.

Here is what Jesus truly emphasized.

©Image Credit: vihatran via 123RF

Hell is a real spiritual consequence, not a fictional threat
Jesus referred to hell using the word Gehenna, a well-known valley outside Jerusalem associated with destruction and rejection. His audience recognized it as a powerful symbol of loss and judgment.

By using this term repeatedly, Jesus made clear that He spoke about a genuine spiritual outcome, not a poetic metaphor meant to entertain. He wanted people to understand that life carries eternal significance and that human choices ripple beyond the present moment.

Jesus treated hell as a serious reality tied to moral responsibility.

Every day choices quietly shape a person’s eternal direction
Jesus consistently connected behavior to destiny. He taught that love for others, forgiveness, honesty, humility, and obedience matter deeply. Spiritual life was never just about belief in the mind, but transformation in action.

He warned that selfishness, cruelty, and persistent rejection of God slowly harden the heart and redirect a person’s path.

God’s desire is rescue, not punishment
Throughout His teachings, Jesus described God as a Father who runs toward lost children, searches for missing sheep, and welcomes those who turn back home.

Warnings about hell always appeared alongside invitations to repentance and renewal. Judgment existed, but it was never God’s first choice.

A religious image cannot replace a changed heart
Jesus confronted religious leaders who looked holy on the outside but lacked compassion, justice, and humility on the inside. He warned that rituals, titles, and public reputation offer no protection when the heart resists truth.

For Jesus, faith meant a life shaped by love, integrity, and obedience, not by religious performance.

©Image Credit: sergray via 123RF

The deepest pain of hell is separation from God
Jesus described judgment primarily as exclusion from God’s kingdom, resulting in the loss of joy, peace, and wholeness found in God’s presence.

The tragedy was relational before anything else. To be cut off from the source of life itself was the ultimate loss.

©Provided by: FODMAP Everyday

Jesus warned people because He cared deeply about them
He spoke firmly, sometimes urgently, because He loved. Just as a doctor speaks plainly about a deadly illness, Jesus spoke honestly about spiritual danger to protect people, not to control them.

His tone combined truth with compassion.

©Image Credit: dolphfyn/123RF

Forgiveness always remained possible
Jesus never portrayed anyone as beyond hope. He welcomed sinners, doubters, failures, and outsiders. As long as someone was willing to turn back, grace remained available.

Hell was never described as God’s desire, only the result of persistent refusal to accept life with Him.

©Image Credit: lendig/123RF

Key Takeaways
Jesus did not preach fear; he preached responsibility wrapped in mercy. His teachings about hell pointed people toward a better path, one marked by love, humility, and reconciliation with God.

Humans’ learning about nuclear concepts that led to nuclear energy and nuclear bombs was one of the most important turning points in human history.

This represented the first time that humanity started ‘playing’ with technology that could literally destroy our whole species (not to mention the whole world). In addition, nuclear technology meant the potential for almost limitless clean energy, even if we haven’t yet taken full advantage.

So, if nuclear technology is such an important point in our evolution, it would make sense if aliens (if they exist) would take an interest.

Since the earliest days of nuclear testing and development, there have been reports of strange lights and unidentified objects up in the atmosphere around nuclear facilities. A group of researchers decided to gather up all the data on this subject (there is a lot) and put it together to try to see if it could be determined what was really causing the unidentified aerial phenomena.

The study was published in Scientific Reports, and while they definitely cannot confirm that it was aliens, they also can’t completely rule it out.

The team looked at transient ‘star-like’ objects that were reported or even seen in images, often taken from cameras at these facilities. The Vanishing & Appearing Sources During a Century of Observations project has been around since 2017, working on compiling all of these reports.

In the paper, the team writes:

“These short-lived transients (lasting less than one exposure time of 50 min) have point spread functions and are absent in images taken shortly before the transients appear and in all images from subsequent surveys. In some cases multiple transients appear in a single image, exhibiting characteristics not easily accounted for by prosaic explanations (e.g., gravitational lensing, gamma ray bursts, fragmenting asteroids, plate defects).”

Given the fact that this all happened over half a century ago makes it hard to identify exactly where the lights or sightings came from. The researchers wrote in the paper:

“From 1951 until the launch of Sputnik in 1957, at least 124 above-ground nuclear tests were conducted by the United States (US), Soviet Union, and Great Britain. In some circumstances, nuclear radiation is known to cause a visible glow (i.e., Cherenkov radiation). […] Consistent with this concept, glowing ‘fireballs’ in the sky were reported in multiple instances to occur shortly after nuclear tests in locations where significant nuclear fallout was expected.”

There is no confirmed explanation for these events. Not surprisingly, many will say that they could be either aliens or drones sent by aliens to investigate the fact that humans have entered a nuclear age.

Another option is that nuclear tests could cause an atmospheric phenomenon that is not yet fully understood. Since nuclear tests are pretty rare (thankfully), it is not something that is easy to study.

While they may not know what caused these types of signings, it does seem clear that something happened around the nuclear testing sites during that time period, given all the evidence.

OVER A LARGE BOX of untouched donuts in Washington’s Longworth House Office Building, Congressional representatives sat rapt as a visiting Brazilian neurosurgeon described what it was like to stare back at the large lilac-colored eyes of a highly intelligent, nonhuman being.

So, not your usual Capitol Hill meeting.

The closed-door session on Jan. 15 brought together three members of Congress seeking greater government transparency on Unidentified Anomalous Phenomena, long called UFOs, and a group of Brazilians who say they witnessed the crash of an otherworldly spacecraft and later encountered its nonhuman occupants.

Coming thirty years after the striking events, the private Washington meeting (to which we alone had media access), followed by a public press conference five days later, raised the prospect of unprecedented Brazilian-American cooperation in unraveling the mysteries of one of the best researched—and shocking—UFO cases on record.

The witnesses included the highly respected neurosurgeon, a forensic pathologist, and a geography teacher. They were brought to the United States by filmmaker James Fox, who interviewed more than two dozen witnesses for a new feature documentary that expands on a 2022 version of his film Moment of Contact. Fox has been investigating the case, with his Brazilian counterpart Marco Aurelio Leal, for over two decades.

“This could settle the debate once and for all that we’re not alone,” Fox told the packed news conference, which he organized at the National Press Club on Jan. 20.

The story is this: On January 13, 1996, in the countryside outside the municipality of Varginha, Brazil, the geography teacher—also an ultralight pilot—reported seeing a cylindrical craft trailing smoke and crashing to Earth. A week later, three girls walking home through a vacant lot reported encountering a cowering creature with reddish eyes and brown oily skin that reportedly communicated its suffering through its eyes. Before long, the streets of Varginha were filled with military trucks and emergency vehicles amid rumors of the capture of two nonhuman beings, one later hospitalized, and a clandestine American operation that spirited them out of Brazil.

Fox said that now, for the first time, he knows the names of those who were in possession of videos of the purported nonhuman entities. Despite the difficulties in obtaining them, he said, “I never give up.”

Susan Gough, a Pentagon spokesperson, did not reply to requests for comment.

The Department of Defense All-domain Anomaly Resolution Office (AARO), with a mission to scientifically investigate UAP, stated in a 2024 report that “none of these investigations (including USG, foreign, and U.S. academic efforts) reached the conclusion that any of the UAP reports indicated extraterrestrial origin.”

But AARO may not have a free hand. As Fox recalled, in 2024, he met with AARO staff to discuss a video staff members had obtained. They discussed the Varginha case, among others. At one point, AARO director Dr. Jon T. Kosloski came into the room. Fox says he asked Kosloski if there was a plan to inform the public about “what we are ultimately dealing with.” Kosloski replied, “I can’t part my hair without the approval of the DOD. And you can quote me on that.”

There is no question that the Varginha case lacks hard data. No one has yet been able to come up with photographs or videos, physical evidence, official documentation, or medical records that could help verify the episode. Yet over two dozen witnesses to many aspects of the case have come forward independently, providing pieces of a puzzle that seem to fit together to tell a compelling story.

The Congressional meeting, held in Tennessee Representative Tim Burchett’s office, drew two fellow Republicans—Anna Paulina Luna of Florida, chairwoman of the House’s Task Force on the Declassification of Federal Secrets, and Eric Burlison of Missouri—along with staff members. Two Democrats with a longstanding interest in UAP issues—Jared Moskowitz of Florida, and Andre Carson of Indiana, a member of the House Select Committee on Intelligence—were invited but unable to attend.

“Can you take it from the top?” Luna asked the visiting neurosurgeon, Dr. Italo Venturelli, 73, at the beginning of the meeting, “Who brought the being in? I want detail about what the interaction was, from point A to point B.”

Burchett also pressed a question: “Was the being able to communicate in any way? Was it telepathic or anything like that?”

Dr. Italo (as he prefers to be called), who was on duty that day in Regional Hospital in Varginha, said the captured being was initially treated by his colleague, Dr. Marcos Vinico Neves, who sutured a wound on its cranium. Neves died in 2018, and no medical records were kept of this procedure, according to Dr. Italo.

He says he was shown a brief black and white video of the patient and then spent three or four minutes at its bedside, having been asked to visually examine it after the procedure.

“I’ve been a doctor for forty-six years and have performed thousands of surgeries,” Dr. Italo said in an interview before the meeting. “To me, it was obvious that this was not a human being.”

“It looked like a seven-year-old child,” the neurosurgeon told the representatives with help from a translator in attendance. “Its eyes were lilac color. Both eyes and the cranium were teardrop-shaped. It transmitted calm and tranquility.”

The doctor said it seemed to him that his patient was at peace with everything that was happening, and that he sensed it possessed intelligence greater than his own. He also described feeling as if he were looking at an angel.

“I wouldn’t say it communicated telepathically; it communicated empathetically,” he said, “through its eyes.”

“What did the hands look like?” Luna asked.

Dr. Italo demonstrated, holding up three fingers and a thumb.

He said he had fixated on the eyes, which seemed to communicate power, concentration, and compassion. At one point, the being looked at him, looked out the window at the blue sky, and then looked back at the doctor, as if to communicate its wish to be released.

Burlison, taking notes, asked if it was wearing clothing. Bare above the sheet, said Dr. Italo. The skin was white, the torso was slim, and there were no nipples. A small mouth. A sliver of ears.

Burlison asked if any other medical staff or doctors could corroborate the story.

Yes, said Dr. Italo, but most doctors are afraid to speak out because they have been threatened, or for fear of damage to their careers.

“It’s very important to get the others,” Burlison said.

Dr. Italo said that a near-fatal heart attack and other recent medical issues persuaded him to break his silence last year and provide his full story to Fox for the first time, even though he still works full-time at Regional Hospital.

Carlos de Sousa, the geography teacher and ultralight pilot, told the representatives that he saw a “cigar-shaped” craft that he first thought was a blimp with a lateral tear trailing white smoke and struggling to stay aloft before crashing near a highway.

He said he drove over to help any survivors and was overtaken by a strong odor of ammonia and rotten eggs. Picking up a piece of what looked like aluminum, de Sousa said he was able to crumple it in his fist, but it then immediately sprang back to its original shape. Military trucks arrived within minutes. A soldier approached him and aimed a gun at his head, demanding, “Leave now, or I’ll split your skull,” de Sousa said. Dropping the fragment, de Sousa fled, but said he was confronted shortly afterwards by two men in an unmarked dark vehicle who threatened his family and demanded his silence. He did not speak about the incident for decades.

A third Brazilian visitor, Dr. Armando Fortunato, who has been a forensic pathologist and criminal medical examiner for the Civil Police for over three decades, told the representatives that he had performed an autopsy on a young military police officer, Marco Chereze, who had grabbed one of the beings during its capture and then died a few weeks later from a severe infection after it inadvertently scratched him.

Dr. Armando, as he likes to be called, said a legal request has been filed to exhume Chereze’s body with hopes of collecting bacteria—or even DNA samples—that could undergo further analysis.

Dr. Armando handed the representatives a signed statement from Dr. João Janini, 89, a specialist in pathological anatomy whose biography states he has performed over 50,000 autopsies. Janini attested that he had found a rare form of a bacterium “of extremely high aggressiveness and lethality” in the tissue samples from Chereze. The characteristics of the infection went so far beyond the limits of what is conventional that, in his opinion, “it raises the hypothesis of its alien origin.”

Accounts from former U.S. officials involving alleged UAP crash retrievals and related recoveries of nonhuman bodies have continued to surface, although the Defense Department dismisses them as unfounded.

In a 2023 Congressional hearing, David Grusch, a veteran of the National Geospatial-Intelligence Agency, the National Reconnaissance Office, and the Defense Department’s UAP Task Force, testified under oath that the U.S. has retrieved vehicles and “biologics” of exotic origin.

“Biologics came with some of these recoveries,” he asserted, referring to nonhuman bodies and tissue samples, citing “people with direct knowledge on the program I talked to that are currently still on the program.” Since then, other former officials with high security clearances have echoed his statements, sometimes under oath.

Kirk McConnell, who served for 37 years on the staff of the Senate Armed Services Committee, the Senate Intelligence Committee, and the House Intelligence Committee until retiring in early 2024, opened the Jan. 20 press event. He was among the staff from the two Senate Committees who collaboratively investigated the UAP issue on behalf of senators from both parties.

McConnell told the audience that reports similar to those from the Varginha case reached senators and staff conducting these investigations. The interested senators, who included now-Secretary of State Marco Rubio, held meetings and interviews in sensitive compartmented intelligence facilities “with very credible sources reporting both direct and secondhand knowledge of the reality of highly intelligent nonhuman beings, government retrievals and reverse engineering of craft not made by human beings, and the recovery of bodies of non-human beings,” McConnell said.

He had attended some of these classified meetings.

The reports provided to Congress included alleged hidden government activities similar to those recounted in the Varginha case, stretching across many decades. “So what these folks are going to tell you today are astounding, but they’re not the only credible testimony about such events,” McConnell said.

In a video statement screened at the press conference, Jacques Vallée, a French-American computer scientist who has worked on projects at NASA and DARPA, and has been a leading thinker and writer on UFOs for over fifty years, cited a “data warehouse system” that he and a scientific team compiled for the Defense Intelligence Agency.

In addition to over 200,000 reports of anomalous objects in flight, Vallée said the database includes “hundreds of reports of creatures, live or dead, associated with crashed or landed vehicles of unknown provenance, including some similar to those in Varginha,” and that creatures in other documented cases breathed air normally.

Vallée said that the Varginha case is similar to many classified cases in scientific and medical records, but it also “presents exceptional new knowledge”, especially “in the professional description of the anatomical and behavioral features of the live creature recovered by authorities within a short time of the crash, and to the point of its death.”

During the private discussion in Burchett’s office, Dr. Italo said he had learned that the being he saw was taken to ESA military base, then to Campinas, and then to the States.

“All the people we talked to said the exact same thing,” Fox told the representatives.

Luna said Congress should seek Air Force flight logs and a landing permit to confirm any American retrieval operation of bodies and crash debris from Varginha, although it is uncertain whether any paper trail exists.

Later, at the press conference, Col. Fred Claussen, a retired and highly decorated U.S. Air Force colonel who held a top-secret clearance, outlined ways the alleged secret U.S. mission might yet be documented. He said that a Brazilian air traffic controller, Marco Feres, reported that on or about Jan. 20, 1996, a U.S. Air Force cargo plane, most likely a C17, took off from an American base and landed at Viracopos airport in Campinas to pick up an unusual cargo before departing for an unknown location in the U.S.

Any such cargo plane mission, the colonel said, would require paperwork from Air Mobility Command at Scott AFB in Illinois and the Air Mobility Wing at Charleston AFB in South Carolina. Air refueling would require more documentation, as would an international flight plan to Brazil, even if the mission were classified, Claussen said, adding that at Campinas, there would need to be more refueling records and another international flight plan.

Even without a paper trail, he said he believed that thirty to forty Americans involved with the operation should have direct knowledge of this flight and its purpose.

“Here is my plea,” Claussen concluded. “If you were a participant and have knowledge of this mission, come forward.”

McConnell followed by saying there was general misunderstanding that nondisclosure agreements signed by intelligence figures barred them from sharing their information about UAP recoveries with Congress. They were not liable, he said, if they presented their accounts in properly secure facilities like SCIFs. In fact, he said, “It’s illegal to withhold information from Congress.”

No one has ever been prosecuted for providing classified information to Congress, McConnell said. In fact, the President himself “could affirm disclosure to Congress with the stroke of a pen or [on] social media.”

While greater UAP disclosure has been widely regarded as a bipartisan issue in Congress, “we’re not yet at the tipping point for most members of Congress,” McConnell said.

A joint evidence-seeking operation between Brazilians and Americans could be in the works. Brazilian Senator Eduardo Girão, who represents the coastal state of Ceará and led a Brazilian Senate hearing on UAP in 2022, came to Washington to meet with members of Congress and attend the press event.

Acting as a private citizen and not representing the Brazilian Senate, Girão spoke from the podium and commended the three Brazilian witnesses for their courage in speaking out.

During a break, he spoke with Burlison, who said he had gotten up at 4 a.m. that morning to fly from Missouri so he could attend the news conference and present a public statement (the other members did not fly back in time to attend).

“Are there videos that you think you might be able to get access to, any other material evidence?” Burlison asked Girão.

“I’m going to try,” Girão said.

The two discussed the need for a joint effort to acquire tangible evidence that could help validate the incident. Burlison described having seen interesting UAP videos, but “nothing that is definitive 4K.” He told the Brazilian senator about key American officials who have come forward, including the current Secretary of State.

Obtaining the evidence he would like to see has been difficult, Burlison said, because “there are several government entities that are controlling this and some are willing to be more cooperative, so unfortunately we’re not getting everything.”

Six other Brazilians who wanted to provide testimony on the Varginha case were denied visas by the State Department on the grounds that they might overstay their visas and attempt to remain in the U.S. So, in December, Fox and his producing partner, Aline Kras, returned to Brazil to compile their testimonies on videotape for presentation at the press conference.

One of these witnesses, Liliane Silva, now a 46-year-old early childhood teacher, said that on Jan. 20, 1996, at about 3:20 p.m., she and her sister and a friend were taking a shortcut home when she noticed some graffiti on a wall. Underneath it, she stated, “I saw the creature.”

“It was short in stature, with red eyes, brown skin, as if covered in oil,” Liliane recounted.

“When I saw it, I had a terrible feeling as if the world had stopped.” She screamed to alert the others. “The creature looked at me,” she continued. “I looked into its eyes. It gave me a sensation that it was suffering, that it was asking for help, hiding from someone.”

Then, she and the other girls ran.

Her sister, Valquira Silva, and their friend Katia Xavier provided similar details in their own video statements. It had “three fingers on its hand, a big foot,” Katia said, adding: “It seemed he was suffering, asking me for help.”

So, not your usual Capitol Hill meeting.

In her statement, the mother of the Silva sisters, Luiza Helena da Silva, said she went back with Katia about twenty or thirty minutes later to find the creature gone. But she said it left behind a footprint with three large toes and an acrid odor that remained in her nose for several weeks.

Sometime later, the mother said she was visited by four strange men dressed in black, offering a briefcase filled with cash if her daughters would go on television and lie by describing the creature as a calf, a sick dog, or a sick human. She refused, saying she was very frightened by the visit.

Yet another videotaped witness, unnamed and his face obscured, said he was in the army in 1996 and helped transport the being from the hospital in Varginha to Três Corações and from there to Campinas, where other soldiers took over. Upon returning to Três Corações, he said, “There was talk the Americans had the creature, having transported it to an undisclosed location.”

At the news conference, Dr. Italo was questioned about his contact with the nonhuman being in the Varginha hospital room. Was it bleeding? Agitated?

“It was initially OK, it just looked out the window,” Dr. Italo replied. He said that instantly, “I was not there as a doctor anymore. The being was looking straight at me. The more he looked at me, the more I had a feeling of peace; it was transmitting peace. It looked at everything happening as if it was taking notes, like a great observer of everything happening around it.”

Asked if he had had any subsequent contacts with nonhuman intelligence, the doctor replied simply, “No.”

Fox said the videos of the entities are held by people too afraid to release them, but that for the first time, he may have the help of Brazilian Senator Girão and Representative Burlison, who is currently working on strengthening whistleblower protection for UAP witnesses.

In Varginha, individuals continue to come forward. On Jan. 26, Rosangela Ramos appeared on camera with James Fox, saying that her late husband, Pedro Luiz Aguiar, the chief of police in Três Corações in 1996, who had been on duty during the incident, claimed he had also witnessed the creature, although she had no further details. Aguiar died in December.

At the news conference, Burlison called for international transparency.

“If there’s any government that’s holding information about the knowledge of whether or not we are alone or not alone in the universe, that is not for any government, no matter how powerful it is, to withhold from the rest of humanity,” Burlison said, to general applause.

Dr. Italo says he has no regrets about coming forward.

“The truth is, I saw the being,” he said. “He was not a being from our planet. We are talking about something that changes the concept of humanity.”

“It’s important for people to know.”

Something Is Moving Under the Oceans – and Navies Know It

For decades, unexplained encounters with unidentified objects have not been limited to the skies. Beneath the ocean’s surface, military submarines from multiple nations have reported interactions with fast-moving, intelligent, and technologically superior objects commonly referred to as Unidentified Submerged Objects (USOs). These encounters, discussed in detail on Jim Harold’s Paranormal Podcast, raise serious questions about what may be operating in Earth’s oceans and why official acknowledgment remains minimal.

Why Submarine Encounters Are Uniquely Concerning

Submarines operate in extreme isolation, with little margin for error. A single hull separates the crew from crushing ocean pressure, and in the case of ballistic missile submarines, these vessels carry nuclear weapons capable of triggering global catastrophe. Any unidentified object interacting with such platforms represents not only a mystery but a significant strategic and security concern.

Reports from submariners are especially notable because these individuals rely on advanced sonar, navigation systems, and strict operational protocols. When unexplained objects are detected repeatedly under such conditions, dismissing the encounters becomes increasingly difficult.

Soviet Navy Encounters and the “Croakers”

During the 1970s and early 1980s, the Soviet Navy documented numerous underwater encounters involving strange acoustic signals. These sounds resembled croaking or frog-like noises, leading Soviet crews to nickname the objects “Kavaki,” meaning “croakers.”

• Richard Dolan Intelligent Disclosure with Jim Harold: The Submarine UFO Encounters the Military Refuses to Acknowledge:

According to the accounts, these submerged objects demonstrated extraordinary capabilities:

• They could rapidly approach and withdraw from submarines
• They circled vessels in a deliberate manner
• They displayed speeds far exceeding known underwater technology

Initially, Soviet analysts suspected advanced American devices. However, the performance of these objects quickly ruled out known U.S. technology. The conclusion was troubling: whatever these objects were, they did not belong to any recognized military power. Although studies were reportedly conducted, their findings remain classified, and public information largely disappeared following the collapse of the Soviet Union.

Chinese Military Observations and Silent Documentation

Public information about Chinese encounters with UFOs and USOs is scarce, but evidence suggests that China has quietly taken the phenomenon seriously. Since the late 1970s, particularly after China began opening up to the world, the country has reportedly collected and analyzed a large number of UFO reports, comparable in volume to those in the United States.

China’s military is said to operate a structured, multi-level reporting system that gathers sightings from across the country and subjects selected cases to deeper analysis. While underwater sightings are rarer than aerial ones, China’s heavy naval presence in strategic waterways such as the South China Sea makes it highly likely that USO incidents are monitored, even if never publicly discussed.

A Pattern That Predates Modern Technology

One of the most compelling aspects of submarine and maritime UFO encounters is their historical consistency. Accounts stretching back centuries describe objects emerging from or interacting with the ocean in ways that closely resemble modern reports.

A well-documented case from August 12, 1825, recorded by Royal Navy ship physician Andrew Bloxom, describes a glowing orange orb rising from the ocean at night. The light was so intense that objects on the deck were clearly visible. The object submerged, re-emerged, and eventually disappeared. This account predates modern aviation and submarine technology by generations.

A similar incident occurred nearly 150 years later in 1971, involving the USS John F. Kennedy. A glowing orange object appeared near the aircraft carrier, coinciding with system disruptions and a rapid shift to battle stations. The similarities between these two events suggest a long-standing phenomenon rather than isolated anomalies.

Shapes, Behavior, and Possible Changes Over Time

Most reported USOs appear to maintain their shape and structure while transitioning between water and air. Spherical objects are among the most frequently described, often glowing orange or appearing metallic gray when unilluminated.

Triangular objects represent a notable development. While rare or uncertain in earlier reports, triangular USOs begin appearing more consistently from the late 1970s onward. This raises questions about whether the phenomenon has evolved or whether earlier observers lacked the means to accurately identify such shapes.

Even in the 19th century, sailors reported mechanical-looking objects over open oceans. An 1870 account from the middle of the Atlantic Ocean describes a structured craft flying beneath cloud cover at a time when no known human technology could explain such behavior.

Transmedium Capabilities: The Defining Feature

Perhaps the most significant finding discussed in the source material is that most USO encounters are transmedium in nature. Based on a dataset of over 670 carefully selected cases:

• More than half involved objects entering or exiting the water
• Roughly one-fifth were observed exclusively underwater
• A smaller percentage hovered just above the water’s surface

These objects appear capable of moving between air and water without visible propulsion, without slowing down, and without changing shape. Such performance defies conventional engineering and challenges current understanding of physics.

Why Militaries Remain Silent

The lack of official acknowledgment may not stem from disbelief but from uncertainty. Admitting the presence of unidentified objects capable of outperforming submarines and disabling systems would raise profound questions about national security, technological superiority, and defense readiness.

For military institutions, acknowledging such encounters without an explanation may be seen as more destabilizing than remaining silent.

Submarine UFO encounters represent one of the most overlooked yet potentially significant aspects of the unidentified phenomena. Reported by multiple nations, spanning centuries, and involving trained military personnel, these incidents display remarkable consistency in behavior and capability.

Whether the explanation lies in unknown natural processes, undisclosed technology, or something entirely beyond current understanding, one fact remains clear: the oceans may conceal advanced phenomena that humanity has yet to fully comprehend, and militaries around the world may know more than they are willing to admit.

Afgetapt Bloed, Medisch Nauwkeurige Sneden, En Onbeantwoorde Vragen: De Verminkingen van Runderen (Cattle Mutilations }

Zijn zij de slachtoffers van een onbekend buitenaards experiment...

Inleiding

Sinds de jaren zeventig van de twintigste eeuw hebben mysterieuze en macabere gebeurtenissen de aandacht getrokken van onderzoekers, wetenschappers en wetshandhavers wereldwijd: de zogenaamde koeienmutilaties. Wat begon als sporadische incidenten in de Verenigde Staten, groeide uit tot een archetype van het onverklaarbare en het bovennatuurlijke, met meldingen die zich verspreidden over meerdere continenten. Ondanks decennia van onderzoek en talloze theorieën blijft het fenomeen onduidelijk en omgeven door speculatie.

In dit artikel zullen we het fenomeen van de koeienmutilaties gedetailleerd analyseren vanuit een wetenschappelijk perspectief. We onderzoeken de aard van de mutilaties, de gebruikte methoden, de mogelijke oorzaken, de bestudeerde gevallen en de relevante vragen die nog altijd onbeantwoord zijn. Daarbij zullen we voorbeelden aanhalen, bewijsstukken bespreken en verschillende hypothesen evalueren, zowel natuurlijke als bovennatuurlijke.

De aard en kenmerken van de mutilaties

Medisch en forensisch profiel

Een kenmerkend aspect van koeienmutilaties is de uiterst precieze en doelgerichte wijze waarop de dieren gestript worden van bepaalde lichaamsdelen. Vaak zijn de volgende kenmerken waarneembaar:

• AFGETAPT bloed: Het lichaam is bijna geheel bloedeloos, vaak met duidelijke bloeduitstortingen rondom de wondranden.
• Precisie sneden: De wondpatronen vertonen chirurgische precisie. Sneden zijn recht, relatief glad en oppervlakkig, wat suggereert dat ze met een zeer scherp scherpmes of instrument zijn gedaan.
• Verwijdering van specifieke organen: Vooral de ogen, tong, hart, longen, genitale organen, en gespeende spieren worden vaak verwijderd. De essentiële organen zoals het hart en de longen ontbreken meestal.
• Geen tekenen van geweld of gescheurd: De wonden vertonen geen tekenen van vechtpartijen, beten of scherpe tanden. Er zijn geen sporen van ongevallen of roofdieren, oftewel dieren die dergelijke mutilaties zouden kunnen veroorzaken.
• Ontbreken van bloedstolsels en sporen: Het bloed lijkt uit het lichaam te zijn gehaald met een chirurgische precisie, zonder dat sporen van bloedstolsels of gebruik van traditionele snijwapens zichtbaar zijn.

Voorbeeld van een mutilatie

Een van de bekendste gevallen vond plaats in 1975 in Colorado, Verenigde Staten. Een rund werd gevonden in een weide, met een kleine, gladgesneden wond rond de nek en zonder enige tekenen van strijd. Het dier was bijna volledig ontladen van bloed, en zijn onderlichaam was leeggehaald: de ogen, tong en organen van de romp waren verdwenen. De wond was zo perfect dat sommige onderzoekers dachten aan de werkwijze van een chirurg.

Deze twee verminkte koeien werden woensdag gevonden door boeren uit de omgeving van Parker en Wilford, terwijl het aantal verminkingen in het gebied blijft toenemen. De dode jaarling, die achtergelaten is, werd woensdag in de omgeving van Wilford gevonden en was al enkele dagen dood. Het jaarling had zijn oren, tong en geslachtsorganen niet. Fremont County-deputy Terry Thompson controleert het lichaam van een dode koe, rechts, gevonden op de Margaret McMinn-boerderij in Parker. De koe werd woensdagochtend vroeg gedood en haar geslachtsorganen werden verwijderd en een deel van haar bloed was afgevoerd. Het kantoor van de sheriff heeft geen aanwijzingen over wie de verminkingen uitvoert. Onderschrift gedateerd 2 oktober 1975. | Met dank aan Idaho Falls Post Register

Verzameld bewijs en onopgeloste details

Naast de fysieke kenmerken biedt het bewijs dat vaak wordt verzameld, vragen op die nog altijd niet volledig beantwoord zijn:

• Bloedanalyse: Het bloed dat werd gevonden, vertoonde vaak tekenen van ernstiger bloedverlies dan mogelijk met conventionele methoden te veroorzaken is. Soms was het bloed verder afgeleid van het lichaam door een soort “drainage.”
• DNA-onderzoek: In sommige gevallen werden DNA-monsters uit de wonden gehaald. De resultaten toonden geen sporen van menselijke aanwezigheid of bekende parasieten of bacteriën.
• Elektrisch en chemisch bewijs: Er zijn aanwijzingen dat sommige mutilaties met behulp van geavanceerd technisch of chemisch materiaal worden uitgevoerd, hoewel dit nietconsistent in alle gevallen wordt gevonden.

Mogelijke oorzaken en hypothesen

Omdat de mutilaties zo minutieus en doelgericht lijken, hebben onderzoekers verschillende hypothesen aangevoerd, variërend van natuurlijke tot bovennatuurlijke verklaringen.

Natuurlijke en biologische oorzaken

Predator- of roofdier-aanvallen

Een eerste en voor de hand liggende verklaring is dat roofdieren of andere dieren verantwoordelijk zijn. Echter, afgezien van de duidelijke sporen van dergelijke dieren — tanden, krassen, of sporen op het lichaam — ontbreken in veel gevallen bewijs dat een ander dier de mutilatie heeft uitgevoerd. Bovendien, de chirurgische precisie en het ontbreken van bloedstolsels zijn inconsistent met natuurlijke roofdier-aanvallen.

Infectie of ziekte

Sommigen suggereren dat bepaalde ziekten of parasieten kunnen leiden tot gedragsveranderingen die tot lichamelijke schade leiden. Maar dit verklaart zelden de specifieke sneden en verwijderde organen.

Toegepaste landbouwbehandelingen en medische ingrepen

In de jaren 80 werd gesuggereerd dat boeren of onderzoekers met militaire of farmaceutische technologieën experimenteren, bijvoorbeeld het gebruik van lasers of geavanceerde medische apparatuur, om dieren te markeren of te bestuderen.

Technologische en buitenaardse theorieën

Ufo's en buitenaardse wezens

De meest iconische hypothese is dat buitenaardse wezens betrokken zijn bij de mutilaties. Volgens deze theorie zouden UFO’s of buitenaardse onderzoekers de dieren gebruiken voor experimenten, waarbij zij organen wegnemen voor genetisch onderzoek zonder de rest van het lichaam te beschadigen.

Voorbeeld: In de jaren 70 en 80 werden meerdere meldingen gedaan van Ufo’s die in de buurt van mutilatieplaatsen werden waargenomen. Sommige getuigen meldde dat ze lichtverschijnselen zagen of zelfs buitenaardse wezens.

Militair en geheime experimenten

Een andere verklaring is dat overheids- of militaire instanties geavanceerde technologieën testen, bijvoorbeeld laser- of plasmatechnologieën, en dat de mutilaties onderdeel zijn van experimenten met biologische en genetische technieken. Deze hypothese wordt ondersteund door het feit dat sommige mutilaties lijken op technische experimenten die niet voor het publiek bekend zijn.

Paranormale en bovennatuurlijke verklaringen

Naast de bovengenoemde theorieën bestaan er ook meer onconventionele overtuigingen dat de mutilaties verband houden met bovennatuurlijke factoren, zoals geesten, energieweerstanden of kosmische krachten. Echter, wetenschappelijk bewijs voor dergelijke verklaringen ontbreekt grotendeels.

Analyse van belangrijke casussen

De aard en complexiteit van de mutilaties maken ze tot intrigerende problemen voor wetenschappers en onderzoeksgroepen. Hier volgen enkele belangrijke casussen die illustreren hoe het fenomeen zich voordoet en waarom het nog steeds mysterieus blijft.

Case 1: The Carmichael Ranch (New Mexico, 1979)

In dit geval werd een koe gevonden met een bijna chirurgische snede rond de nek, zonder verwondingen die doen denken aan een aanval door roofdieren. Het bloed was bijna volledig verdwenen. Lab-analyses toonden een afwezigheid van DNA dat overeenkwam met menselijke of dierenlijke bronnen, behalve dat van het dier zelf. De politie concludeerde dat geen natuurlijke oorzaak kon worden vastgesteld.

Case 2: The Norton Farm (Verenigde Staten, 1980)

Een kalf werd gevonden met organen verwijderd onder chirurgisch schone omstandigheden. Dit en soortgelijke gevallen veroorzaakten een golf van publieke angst en media-aandacht. Desondanks bleven de onderzoekers ongelukkig met de afwezigheid van bewijs dat een natuurlijke verklaring konden ondersteunen.

Wetenschappelijke en praktische vragen

Ondanks uitgebreide onderzoeken blijven veel vragen onbeantwoord:

• Hoe worden de wonden zo precies en doelgericht gemaakt?
• Waarom worden organen verwijderd zonder enige zichtbare verwonding of bloedvergissing?
• Welke technologie of middelen zouden hiervoor nodig zijn?
• Hoe kunnen we de afwezigheid van bewijs voor menselijke of dierlijke betrokkenheid verklaren?
• Zijn er overeenkomsten tussen verschillende mutilatiegevallen die op een gemeenschappelijke dader of oorzaak wijzen?

Conclusie

De koeienmutilaties blijven een raadsel dat vele theorieën oproept, van natuurlijke oorzaken tot bovennatuurlijke verklaringen. Hoewel de bewijsstukken vaak wijzen op een uiterst doelgerichte en chirurgisch precieze uitvoering, ontbreekt het aan overtuigend bewijs dat een natuurlijke of menselijke actor verantwoordelijk is.

Wat de ware oorzaak ook moge zijn, het fenomeen benadrukt onze beperkte kennis van biologische, technologische en misschien zelfs bovennatuurlijke processen. Het blijft een onderwerp van fascinerende speculatie en onderzoek, met de wetenschap zeker nog niet klaar met het ontrafelen van dit mysterie.

Aanbevelingen voor verder onderzoek

Om het onbegrijpelijke fenomeen van koeienmutilaties verder te kunnen doorgronden, worden de volgende aanpakken aanbevolen:

• Gedetailleerde forensische analyse van nieuwe gevallen
• Gebruik van geavanceerde DNA- en chemische testingstechnieken
• Monitoring en observatie van mogelijke locaties met behulp van camera’s en drones
• Interdisciplinair onderzoek dat nauwer samenwerkt tussen biologen, ingenieurs, forensisch experts, en astronomen
• Bewustwording en educatie onder betrokken agrariërs en het publiek

In zekere zin biedt het fenomeen niet alleen een uitdaging voor de wetenschap, maar ook een diepere reflectie op onze kennis van de wereld en onze plaats daarin. Het blijft een waarachtig mysterie dat ons echoot dat sommige vragen mogelijk nooit volledig beantwoord zullen worden, tenzij er nieuwe technologieën of baanbrekende inzichten opdoemen.

• OPMERKING PETER2011 : Deze uitgebreide analyse tracht zowel de bewezen feitelijke gegevens als de verschillende interpretaties te belichten, om zo een evenwichtig en informatief beeld te scheppen van de complexe en intrigerende kwestie van de koeienmutilaties.

Ominous warning for humanity as insects mysteriously 'fall silent'

• READ MORE: Americans warned about rise of evil ladybugs 

By STACY LIBERATORE, US SCIENCE & TECHNOLOGY EDITOR

The world's insects are falling silent at an alarming rate, a development a critical care physician has warned may signal a looming crisis for humanity.

Dr Joseph Varon, a Houston-based doctor, issued the stark warning this week, saying insects, including beetles, butterflies, moths, flies, mosquitoes and bees, are disappearing at dramatic rates, a 'critical red flag for ecological instability.'

Varon likened the growing quiet to a dangerous moment in medicine, when a patient suddenly goes silent just before a system failure.

'In medicine, silence can be more alarming than noise,' he wrote in The Defender. 'A patient who abruptly stops voicing discomfort or a monitor that ceases activity may signal system failure rather than resolution.'

'Ecology presents a similar scenario,' Varon added. 'And right now, the silence is deeply concerning.'

This disappearance threatens the foods humans rely on most, including fruits, vegetables, nuts and legumes. 

Key nutrients, vitamins, minerals and antioxidants would also disappear, potentially weakening immune resilience, increasing chronic disease risk, and altering the balance of human health in ways scientists are only beginning to understand. 

'The current silence should not be interpreted as stability. It is a warning,' said Varon.

The doctor warned that without insects, humans will not only loose essential food, but be exposed to an increased risk of chronic diseases

A pivotal warning came from a German study that tracked flying insect biomass in protected areas over nearly 30 years. 

By 2016, researchers found populations had collapsed by more than 75 percent, even in regions shielded from industrial activity.

Global assessments indicate that over 40 percent of insect species are currently in decline. 

Looking ahead, predictions suggest that by 2030, up to a quarter of insect species could be lost or at high risk, highlighting a continued, rapid downward trend.

The losses were documented not in industrial landscapes, but in nature preserves intended to shield wildlife from harm.

'Without insects, food systems collapse not just quantitatively, but qualitatively. Nutrient diversity declines. Resilience vanishes. Dependency on industrial inputs increases,' Varon wrote in The Defender.

From a physician's perspective, the disappearance of insects is a warning signal, a population-level biomarker of environmental stress and toxicity.

'The rise in chronic disease, metabolic dysfunction, and immune dysregulation cannot be cleanly separated from the ecological context in which humans now live,' Varon said.

Dr Joseph Varon, a Houston-based doctor, issued the stark warning this week, saying insects, including beetles, butterflies, moths, flies, mosquitoes and bees, are disappearing at dramatic rates, a 'critical red flag for ecological instability'

'Clinicians may observe these impacts as patients present with increased allergic reactions, resistance to antibiotics, and nutritional deficiencies. 

'For instance, a patient experiencing recurrent respiratory infections could be linked to pollen shifts due to changing insect populations.'

In medicine, when a sensitive system falters first, it signals early danger. Insects occupy that sentinel role in biology. 

Their short lifespans, high metabolisms, and reliance on environmental cues make them exceptionally vulnerable to chemical, nutritional, and electromagnetic disruptions, often long before humans show obvious signs of illness, explained Varon.

Increasing evidence links many of these same exposures to human endocrine disruption, immune dysfunction, neurodevelopmental effects, and metabolic disease. 

Neonicotinoid pesticides, for instance, are designed to target insect nervous systems, yet analogous pathways exist in mammals, influencing neurodevelopment and autonomic function. 

Low-level chronic exposures may not trigger immediate toxicity, but medicine has repeatedly shown that the absence of acute symptoms does not equal safety.

'Imagine a diabetic patient struggling with persistent slow-healing ulcers,' said Varon. 

'These wounds, resistant to typical treatment, become a vivid illustration of micronutrient decline due to pollinator loss.'

Deficiencies in vital nutrients like vitamin C and zinc, essential for immune defense and tissue repair, show how pollinator loss translates into real-world health consequences, he added.

'It is essential for medical professionals to integrate environmental health assessments into their practice, amplifying the connectivity between ecological and human health,' said Varon.

By acting now, clinicians can help avert an ecological crisis and ensure a sustainable future for both the planet and human life.

'Civilizations do not fall only from war or economics. They fall when the living systems that sustain them are quietly dismantled.'

Op zo’n 5 miljard lichtjaar afstand heerst de immense sterrenstelselcluster MACS J1149. De James Webb-ruimtetelescoop legt dit kosmische zwaargewicht nu met ongekende scherpte vast en onthult hoe zijn verpletterende zwaartekracht het licht van het vroege heelal buigt en vervormt.

Diep in het sterrenbeeld Leeuw (Leo), op een duizelingwekkende afstand van ongeveer 5 miljard lichtjaar, heerst een ware titan: sterrenstelselcluster MACS J1149.5+2223. Deze verzameling van honderden sterrenstelsels, bijeengehouden door de allesbepalende zwaartekracht, is nu vastgelegd in verbluffend detail door de James Webb-ruimtetelescoop. Het nieuwe beeld onthult niet alleen de indrukwekkende inwoners van de cluster zelf, maar ook hoe dit kosmische zwaargewicht fungeert als een natuurlijke telescoop voor het observeren van de verste uithoeken van het universum.

De James Webb-ruimtetelescoop legde deze opname van MACS J1149.5+2223 vast met zijn Near-Infrared Camera (NIRCam), een compositie van zes verschillende golflengten van 0,9 tot 4,44 micrometer, om de structuur en samenstelling van de sterrenstelsels in ongekend detail te onthullen.

Een natuurlijk zwaartekrachtlens laboratorium

De werkelijke kracht van MACS J1149 schuilt in zijn kolossale massa. De zwaartekracht van deze cluster is zo immens dat ze de structuur van ruimtetijd rondom zich vervormt. Licht van sterrenstelsels die nog eens véél verder weg staan, moet op zijn miljarden jaren durende reis naar de aarde door dit vervormde gebied reizen. Het gevolg is een fenomeen dat astronomen gravitationele lensing noemen: het licht wordt afgebogen en versterkt, alsof het door een kosmisch vergrootglas gaat. Op Webbs opname (hierboven) is dit overal zichtbaar, van subtiel uitgerekte sterrenstelsels tot bizarre, gerekte vormen.

Een kosmische celebrity onder de loep

Deze eigenschap maakt MACS J1149 tot een ware ‘celebrity’ voor astronomen. De cluster was eerder al één van de zes nauwlettend onderzochte regio’s door het baanbrekende Frontier Fields-programma van de Hubble-ruimtetelescoop, specifiek geselecteerd vanwege zijn sterke lenswerking. Ook de Very Large Telescope van de Europese Zuidelijke Sterrenwacht (ESO) heeft zijn blik op de cluster gericht, maar ook radiogrondtelescopen en orbitale röntgentelescopen zoals Chandra hebben MACS J1149 vaker onderzocht. Recent onderzoek gebruikt deze voorgaande waarnemingen in combinatie met nieuwe gegevens om de massa-verdeling binnen dergelijke clusters en hun rol in de evolutie van sterrenstelsels verder te duiden.

Webbs uitzonderlijke gevoeligheid in het infrarood gaat nu een stap verder. Zijn instrumenten, zoals NIRSpec en NIRCam, worden ingezet in programma’s zoals CANUCS om via clusters als MACS J1149 de allervroegste sterrenstelsels te bestuderen. Ze ontrafelen hun stervorming, chemie en de rol die ze speelden tijdens het tijdperk van de reïonisatie, toen de eerste lichtbronnen de kosmische duisternis doorbraken na de oerknal.

We schreven vaker over dit onderwerp, lees bijvoorbeeld ook ‘Eén jaar na de lancering van James Webb kunnen astronomen hun geluk niet op: de telescoop maakt het onzichtbare en ondenkbare zichtbaar‘ of ‘De eerste sterrenstelsels in het universum waren veel helderder dan verwacht‘.

Een venster op het vroege heelal

De nieuwe James Webb-opname is dus meer dan een adembenemend plaatje. Het is het begin van een nieuw hoofdstuk in de studie van deze kosmische reus. Door het lensvermogen van MACS J1149 te combineren met Webbs ongeëvenaarde scherpte, kunnen astronomen verder terugkijken in de tijd dan ooit tevoren. Op deze manier blijft deze cluster, een reus op 5 miljard lichtjaar afstand, ons een uniek venster bieden op de geboorte en evolutie van de eerste structuren in ons universum.

NASA is gearing up for the first crewed journey to the Moon in over half a century, a mission that could launch as soon as two weeks from now.

And next year, the agency will finally attempt to return astronauts to the lunar surface itself as part of its Artemis 3 mission, which will dramatically increase the already considerable stakes.

Particularly when it comes to stepping out of the spacecraft — the agency has yet to pick between Blue Origin and SpaceX’s offerings in that regard — staying protected from the extreme temperature swings, space radiation, and lack of atmosphere is extremely challenging.

That’s not to mention the physical limitations of an extremely bulky spacesuit, which could physically tax astronauts even more than stepping outside of the International Space Station during a spacewalk.

As Ars Technica reports, former NASA astronaut and microbiologist Kate Rubins, who retired last year and has logged 300 days in space, recently voiced her concerns over the Moon suit that private space company Axiom Space has been developing for NASA as part of a $228 million contract.

“What I think we have on the Moon that we don’t really have on the space station that I want people to recognize is an extreme physical stress,” she said during a recent meeting of the National Academies of Sciences, Engineering, and Medicine.

Besides not getting any sleep, Rubin warned that people will be “in these suits for eight or nine hours” and doing extravehicular activities (EVAs) “every day.”

Compared to the suits NASA astronauts wore during the Apollo missions, the Axiom Space suit is considerably heavier. While a sixth of gravity will greatly alleviate some of that heft, they still weigh in at 300 pounds. At the same time, Moon walkers will enjoy greatly enhanced flexibility, allowing them to kneel down to pick up objects, for instance.

“I think the suits are better than Apollo, but I don’t think they are great right now,” Rubin warned, noting “flexibility issues” and the reality that “people are going to be falling over.”

In remarks directly to Ars, Rubin elaborated, emphasizing that the suits are “definitely much better than Apollo,” but remain “still quite heavy.”

Even something as simple as getting back up after a fall — as demonstrated by the many Apollo astronauts who took a tumble while on the Moon — involves a type of “jumping pushup,” as Rubins told Ars, which is a “non-trivial” and “risky maneuver.”

Not everybody is as concerned about the Axiom Space suit. Current NASA astronaut and physician Mike Barratt argued in remarks during the committee meeting that the “suit is getting there,” pointing out that “we’ve got 700 hours of pressurized experience in it right now.”

“Bending down in the suit is really not too bad at all,” he added.

NASA still plans to conduct plenty of tests involving the suit, including parabolic flight, which can simulate the partial gravity of the Moon’s surface. The agency has already put the suit through its paces underwater at NASA’s Neutral Buoyancy Lab.

The agency has until sometime next year to finalize the design for its long-awaited Artemis 3 mission to the lunar surface. At the same time, NASA still has plenty of decisions to make, including how to get down to the lunar surface in the first place.

NASA shared an unusual photo taken by the Curiosity mission. It shows the rover’s “night shift.”

The Curiosity rover is equipped with LED lights. They are part of the MAHLI camera mounted at the end of its robotic arm. Sometimes scientists use them during the day to illuminate areas that are in shadow, such as the interior of boreholes and intake tubes leading to instruments at the bottom of the rover.

In the earlier stages of the mission, the Curiosity team also used these LEDs at night to search for layers or other features on the walls of drill holes that would help them better understand the composition of the rock. But since the mission changed its drilling method, the holes have become too rough and dusty to see any details. 

However, Curiosity recently used LEDs again at night. This happened after drilling a rock called Nevado Sajama on November 13, 2025. After studying the images, the mission specialists noticed that the walls of the borehole were smooth enough to attempt to find layers, and decided to try illuminating the borehole at night. It is this operation that is captured in the image presented.

The drilling at Nevado Sajama was carried out during an exploration of a region full of geological formations known as “boxworks.” These formations crisscross the surface for many kilometers and, when viewed from space, look like giant spider webs.

A momentous event in the history of space exploration is about to take place: for the first time in 54 years, humans will return to the Moon. As part of the Artemis II mission, four astronauts will orbit the Moon and then return to Earth. The entire journey will take ten days.

The Artemis II mission would not have been possible without Artemis I. As part of Artemis I, NASA launched the super-heavy SLS rocket for the first time and tested the Orion spacecraft in deep space. The experience gained during its implementation laid the foundation for the further development of the lunar program. With the launch of Artemis II fast approaching, let’s take a look back at how the predecessor mission went and admire some of its best photos.

Artemis I was launched into space on November 16, 2022. This launch marked the debut of the super-heavy SLS rocket, which is capable of carrying up to 95 tons of cargo into orbit. Incidentally, its first-stage engines, boosters, and side boosters were inherited from the Space Shuttle program.

Eight hours after launch, the upper stage of the SLS performed a maneuver that directed Orion toward the Moon, after which it separated from the spacecraft and was directed into Earth’s atmosphere.

There were no humans aboard Orion. Three mannequins equipped with sensors that measured radiation, acceleration, and vibration levels during flight played the role of the crew. One of them, dressed in a flight suit, was seated in the commander’s chair.

The journey to the Moon took five days. On November 21, Orion performed a close flyby of the Moon, after which it activated its main engine, entering a distant retrograde orbit around the satellite.

While Orion was in a distant orbit around the Moon, NASA engineers monitored the spacecraft’s behavior and collected data on the radiation environment. The spacecraft also took a series of selfies showing it against the backdrop of Earth and the Moon.

On November 28, Orion reached a distance of 432,210 km from Earth. This is the maximum distance achieved during the Artemis I mission.

On December 1, the spacecraft reactivated its engine and left its distant retrograde orbit, beginning its journey home.

On December 5, Orion flew 128 km above the surface of the Moon and performed a maneuver that allowed it to leave the Moon’s gravitational influence.

In the following days, the spacecraft made several course corrections while mission specialists prepared for its landing.

On December 11, 2022, Orion entered Earth’s atmosphere at a speed of 11.2 km/s, which is much higher than missions returning to Earth from the ISS. The spacecraft’s heat shield sustained more damage than expected, but still reliably protected the contents of the crew capsule.

The Orion capsule successfully splashed down west of the California coast near Guadalupe Island. It was soon picked up by a ship and then taken to port. This marked the official end of the Artemis I mission.

With the first launch window for Artemis II now just days away, NASA has shared a glimpse inside the cramped quarters of the Orion spacecraft.

Four astronauts – Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen – will spend 10 days living inside the capsule as they whizz around the moon.

During that time, the crew will stay in a tiny, equipment–filled space, no larger than the back of a Ford Transit.

While NASA says it will use the mission to learn how crews adjust to tight quarters, space fans have pointed out one very obvious problem.

Although Orion is equipped with a toilet and washing facilities, many commenters wondered just how hygienic the capsule will be after a week and a half in space.

On X (formerly Twitter), one sceptical commenter wrote: 'No mention of how they will be in extremely close quarters and will have to change each other's diapers and wipe.

'The smell would be intolerable.'

Another concerned commenter asked: 'Do they change their clothes at all and if so, since there is a woman in the crew, is there privacy for that and toileting?'

Four astronauts will spend 10 days living inside the cramped confines of the Orion spacecraft 

Although Orion has 30 per cent more habitable volume than the Apollo capsule, it is still smaller than the back of a Ford Transit. Pictured (left to right): Jeremy Hansen, Victor Glover, Reid Wiseman, and Christina Koch

On X, some space enthusiasts had serious concerns about the smell that could be caused by four astronauts living, exercising, and using the bathroom in such a small space 

During the Artemis II mission, the four–person crew will launch from Kennedy Space Centre on a round trip passing around the far side of the moon.

Once their Space Launch System (SLS) rocket has pushed the astronauts out into orbit, the early stages will detach and leave Orion to drift by itself through space.

While Orion has 30 per cent more space than the Apollo capsule, it is still absolutely tiny for four people.

Measuring just 3.35 metres (11 feet) in height and five metres (16.5 feet) in diameter at the base, Orion has a habitable volume of just 9.34 cubic metres (330 cubic feet).

For comparison, a Ford Transit van typically has 10 cubic metres (353 cubic feet) of storage in the back.

Conditions are so cramped that NASA wants to study how the crew physically and psychologically adapt to their time in space.

In a video posted to X, NASA explains: 'To better understand how isolation, confinement, and other aspects of spaceflight affect human health and performance, Artemis II crew members will evaluate their activity levels, sleep patterns, movements and interactions for a study called Artemis Research for Crew Health and Readiness – or ARCHR for short.'

The astronauts will wear sports–watch–like wristbands to measure their movements and sleep patterns in real time, as well as completing surveys and motor control tests before and after flight.

Other concerned space fans were worried that there might not be privacy for washing, changing, or using the toilet in the tiny confines of the Orion capsule 

Despite the obvious challenges, a number of commenters on social media were bizarrely unimpressed by the technological and human achievements of spaceflight 

The crew will sleep for eight hours per day in sleeping bag–like hammocks that attach to handrails (pictured) 

In the biggest upgrade over Apollo, Orion features a separate toilet compartment hidden behind a panel in the floor (circled in red)

The Artemis II crew

Reid Wiseman – Commander 

- A US Navy aviator and test pilot with 27 years of experience.

- Wiseman has previously spent 165 days in space onboard the ISS

Victor Glover – Pilot

- A US Navy aviator and test pilot with 3,500 flight hours in more than 40 aircraft 

- Glover served as Flight Engineer on the ISS during a 168–day mission

Christna Koch – Mission specialist

- An engineer and scientist specialising in electrical engineering

- Holds the record for longest spaceflight by a woman, spending consecutive days on the ISS

Jeremy Hansen – Mission specialist

- Selected by the Canadian Space Agency to join Artemis II

- A Canadian Armed Forces fighter pilot, physicist, and experienced aquanaut

However, despite these obvious challenges, some space enthusiasts remained bizarrely unimpressed.

One commenter wrote on X: 'Relax. Once you get used to it, it'll be fine. I could do the trip to Mars in a freakin' Apollo capsule.'

Another said: 'So NASA's gonna put Fitbits on the astronauts? Cool, I've been wearing one for over three years.'

Despite the small amount of space, NASA has managed to fit in a few comforts that should make the journey more bearable.

For those concerned about the smell, Orion is fitted with a modified version of the toilet from the International Space Station known as the Universal Waste Management System.

This is essentially an elaborate vacuum cleaner with a seat and a specialised nozzle that operates by 'using air flow to pull fluid and solid waste away from the body'.

Compared to the toilet on the ISS, Orion's lavatory has been modified to fit in an even smaller space and to be more practical for female astronauts.

Perhaps most importantly, NASA has even found enough space on Orion to fit the toilet in its own tiny room.

The toilet room will also allow astronauts to wash in relative privacy, using liquid soap, flannels and rinseless shampoo to stay clean. Pictured: A training mockup of the Artemis II toilet used to practice on Earth 

The crew will use a similar toilet to the one found on the ISS, known as the Universal Waste Management System (pictured), that uses 'air flow to pull fluid and solid waste away' 

Orion even has room for a compact gym with a flywheel system (pictured) that allows for simple resistance exercises 

On Apollo, astronauts had to simply float in a corner while doing their business, but Artemis II's crew have the luxury of a tiny cabin in the 'floor' of the capsule.

Speaking in a video blog, Artemis II crewmember Jeremy Hansen described this as 'the one place we can go during the mission where we can actually feel like we're alone for a moment.'

This hygiene bay also offers the crew a place to wash in relative privacy, using liquid soap, flannels, and rinseless shampoo to remain clean.

To stay healthy and prevent muscle atrophy while in microgravity, Orion even packs in a compact gym for the astronauts to use.

The crew will use a flywheel device for simple resistance exercises like rowing, squats, and deadlifts for 30 minutes every day.

It's one of the biggest unanswered questions in science: are there aliens out there, and if so, where are they hiding?

Now, a discovery by NASA raising the tantalising possibility that we're not alone after all. 

The US space agency has discovered an exoplanet 146 light–years away that is 'remarkably similar to Earth'. 

Dubbed HD 137010 b, the planet might fall just within the outer edges of its star's 'habitable zone', meaning there could be liquid water on its surface and a suitable atmosphere for life. 

However, any potential aliens living on this planet would need to be well adapted for cold weather. 

'Although of a stellar type similar to our Sun, the star, HD 137010, is cooler and dimmer,' NASA explained. 

'That could mean a planetary surface temperature no higher than –90°F (–68°C). 

'By comparison, the average surface temperature on Mars runs about –85°F (–65°C).'

Dubbed HD 137010 b, the planet might fall just within the outer edges of its star's 'habitable zone', meaning there could be liquid water on its surface and a suitable atmosphere for life

NASA's scientists discovered the rocky exoplanet using data gathered by the Kepler Space Telescope.

This discovery comes from a single 'transit' – the planet crossing its star's face – which was detected during Kepler's second mission, K2. 

While one transit doesn't sound like much, this was enough for the scientists to estimate the exoplanet's orbital period. 

By tracking the time it took for the planet's shadow to move across its sun's face, the team estimated that the planet has an orbital period of 10 hours, compared to Earth's 13 hours. 

Their calculations also suggest it's probably freezing, although there is a chance HD 137010 b could turn out to be a temperate or even a watery world, according to NASA. 

'It would just need an atmosphere richer in carbon dioxide than our own,' the team explained. 

Based on modelling of the planet's possible atmospheres, NASA says there is a 40 per cent chance that the planet falls within the 'conservative' habitable zone around the star, and a 51 per cent chance that it falls within the broader 'optimistic' habitable zone.

'The planet has about a 50–50 chance of falling beyond the habitable zone entirely,' the experts cautioned. 

To confirm whether or not the planet is habitable, the researchers will now conduct follow–up observations – although they admit this is going to be 'tricky'. 

'The planet's orbital distance, so similar to Earth's, means such transits happen far less often than for planets in tighter orbits around their stars (it's a big reason why exoplanets with Earth–like orbits are so hard to detect in the first place),' NASA explained. 

'With luck, confirmation could come from further observation by the successor to Kepler/K2, NASA's TESS (the Transiting Exoplanet Survey Satellite), the still–functioning workhorse for planetary detection, or from the European Space Agency's CHEOPS (CHaracterising ExOPlanets Satellite).

'Otherwise, gathering further data on planet HD 137010 b might have to wait for the next generation of space telescopes.'

KEY DISCOVERIES IN HUMANITY'S SEARCH FOR ALIEN LIFE

Discovery of pulsars

British astronomer Dame Jocelyn Bell Burnell was the first person to discover a pulsar in 1967 when she spotted a radio pulsar.

Since then other types of pulsars that emit X-rays and gamma rays have also been spotted.

Pulsars are essentially rotating, highly magnetised neutron stars but when they were first discovered it was believed they could have come from aliens.

'Wow!' radio signal

In 1977, an astronomer looking for alien life in the night sky above Ohio spotted a radio signal so powerful that he excitedly wrote 'Wow!' next to his data.

In 1977, an astronomer looking for alien life in the night sky above Ohio spotted a radio signal so powerful that he excitedly wrote 'Wow!' next to his data

The 72-second blast, spotted by Dr Jerry Ehman through a radio telescope, came from Sagittarius but matched no known celestial object.

Conspiracy theorists have since claimed that the 'Wow! signal', which was 30 times stronger than background radiation, was a message from intelligent extraterrestrials.

Fossilised Martian microbes

In 1996 Nasa and the White House made the explosive announcement that the rock contained traces of Martian bugs.

The meteorite, catalogued as Allen Hills (ALH) 84001, crashed onto the frozen wastes of Antarctica 13,000 years ago and was recovered in 1984. 

Photographs were released showing elongated segmented objects that appeared strikingly lifelike.

However, the excitement did not last long. Other scientists questioned whether the meteorite samples were contaminated. 

They also argued that heat generated when the rock was blasted into space may have created mineral structures that could be mistaken for microfossils. 

Behaviour of Tabby's Star in 2005 

The star, otherwise known as KIC 8462852, is located 1,400 light years away and has baffled astronomers since being discovered in 2015.

It dims at a much faster rate than other stars, which some experts have suggested is a sign of aliens harnessing the energy of a star.

Recent studies have 'eliminated the possibility of an alien megastructure', and instead, suggests that a ring of dust could be causing the strange signals.

Exoplanets in the Goldilocks zone in 2017 

In February 2017 astronomers announced they had spotted a star system with planets that could support life just 39 light years away.

Seven Earth-like planets were discovered orbiting nearby dwarf star 'Trappist-1', and all of them could have water at their surface, one of the key components of life.

Three of the planets have such good conditions, that scientists say life may have already evolved on them. 

Researchers claim that they will know whether or not there is life on any of the planets within a decade, and said: 'This is just the beginning.'

On January 27, 2026, the Bulletin of Atomic Scientists moved the symbolic Doomsday Clock forward once again, now just 85 seconds before midnight, the closest humanity has come in nearly eight decades and for anyone paying attention, the message is hard to miss: something is off. 

The latest update pointed to an expanding set of destabilizing forces — from nuclear stockpiles and accelerating climate breakdown to disruptive AI capabilities and advances in synthetic biology. Taken together, these technologies and geopolitical tensions form what the group calls a high risk landscape with almost no guardrails. 

“Every second counts and we are running out of time,” warned Alexandra Bell, the organization’s president. 

The Doomsday Clock was created in 1947, at a moment when nuclear brinkmanship between two superpowers kept the world permanently on edge. Today, the picture is far more complex. 

Multiple nations, corporations, and private labs are racing into fields once reserved for classified programs and black budget research. Technologies that barely existed a decade ago are now capable of destabilizing entire systems without a sound. 

Until 2020, the clock had never surpassed the two-minute mark. Now, only seconds remain. 

Daniel Holz, chair of the Bulletin’s Science and Security Board, noted that last year’s warnings produced not cooperation, but secrecy and escalation: “The opposite has happened.” 

Whether we actually cross the threshold is beside the point. The message in 2026 is unmistakable: the window is closing, and those who know aren’t waiting for public consensus. 

The only question now is whether this countdown remains symbolic or serves as advance notice before midnight arrives for real.

Created in 1945 by Manhattan Project Scientists, the 'Doomsday Clock' is a constant reminder of impending global catastrophe. In 2026, the clock ticked closer to midnight than ever before.

NASA’s Hubble Space Telescope continues to reveal the secrets of the universe, three and a half decades after its launch, as a new AI technique from the European Space Agency (ESA) identifies more than 800 previously unreported space objects.

Launched in 1990 and still in operation, the Hubble Space Telescope has amassed a vast archive of data over its decades spent scanning the universe. Now, a recent paper in Astronomy & Astrophysics reports the identification of 1,300 unusual objects by AI in just two and a half days, many of which have never appeared in the astronomical literature.

Hubble Image Analysis

The astronomers behind the new research fed their AI neural network 100 million image cutouts from the Hubble Legacy Archive. These cutouts are tiny—only dozens of pixels wide—yet the AI was able to meaningfully determine what they contained.

Galaxies accounted for most of the anomalous cutouts, typically undergoing mergers or other unusual interactions that distorted their morphologies or left them trailing long streams of stars and gas. Other cutouts were identified as spacetime distortions that bent light from distant galaxies into arcs or rings before it reached Hubble.

More unusual cosmic features were also identified, including galaxies resembling jellyfish with strange tentacle-like streams of gas, and edge-on planet-forming disks that appear like hamburgers in the images (several of which can be seen above).

Perhaps most notably, dozens of the objects were so bizarre that they did not fit any existing classification.

Developing AnomalyMatch

The sheer scale of data amassed in the continually expanding archives of Hubble and other telescopes has become so large that it defies traditional human-led analysis. These advanced space observatories generate data at a rate far exceeding that of earlier eras in astronomy. Prior attempts to open the data to citizen scientists have met with some success, but the backlog has grown too large for those initiatives to fully address. Until now, astronomers have relied on manual analysis and the occasional fortunate discovery made while examining specific targets.

While Hubble was constructed by NASA, ESA researchers David O’Ryan and Pablo Gómez developed the solution leveraged by the team for its analysis of this torrent of data. Specifically, the pair created a neural network called AnomalyMatch, which is designed to examine collections of imagery far more quickly than humans can. Still, AnomalyMatch was trained to perform pattern recognition similar to that of humans, allowing it to “learn” to identify rare and unusual objects hidden in the data.

“Archival observations from the Hubble Space Telescope now span 35 years, offering a rich dataset in which astrophysical anomalies may be hidden,” said lead author David O’Ryan.

Among the objects discovered was a collision ring galaxy, a type of disrupted or bent ring-shaped galaxy.

Exploring Hubble and Other Telescopes

Although the team’s initial paper focuses on data retrieved using the Hubble Space Telescope, the technique can be applied more broadly as well. Other platforms, such as ESA’s Euclid mission, are generating vast amounts of data that AnomalyMatch could help process. Crucially, O’Ryan and Gómez’s neural network results have been manually reviewed by astronomers, who have so far confirmed 1,300 of the anomalies flagged by AnomalyMatch.

“This is a powerful demonstration of how AI can enhance the scientific return of archival datasets,” co-author Pablo Gómez said. “The discovery of so many previously undocumented anomalies in Hubble data underscores the tool’s potential for future surveys.”

Future advanced space observatories will also benefit from the implementation of AnomalyMatch. For instance, NASA’s upcoming Nancy Grace Roman Space Telescope will provide a wider field of view than the James Webb Space Telescope, offering yet another enormous data set for astronomers to search through in the years ahead.

The paper, “Identifying Astrophysical Anomalies in 99.6 Million Source Cutouts from the Hubble Legacy Archive using AnomalyMatch,” appeared in Astronomy & Astrophysics on December 16, 2025.

EXCLUSIVE - I've seen possessed children scream like beasts and strung up like puppets... these chilling exorcism cases PROVE hell is real

By STACY LIBERATORE, US SCIENCE & TECHNOLOGY EDITOR

There is a hidden battlefield within our world, where forces of light and darkness collide, believers say, in a conflict that sometimes spills into everyday life. 

In its most extreme form, the clash is described as possession: a person seemingly seized by demonic beings, their body overtaken, their voice and movements warped into something not quite human. 

For Anglican reverend Chris Lee, 43, this is not a theological abstraction but a reality he has lived with for nearly two decades. 

Speaking to the Daily Mail, Lee said he first began witnessing exorcisms after moving to rural Tanzania aged 24 for mission work while training to become a priest. 

It was there, he said, that he encountered what he described as 'profound things, miracles and movements of darkness and light' that convinced him he was being called into ministry. 

Within just a month of arriving, Lee said he received an urgent call about a student who was violently ill, screaming, vomiting and convulsing in a way he believed went far beyond any normal sickness. 

Other encounters followed, as Lee recalled a teenage boy inside a church who suddenly 'leapt up into the sky,' screamed like a beast, and bolted into the woods, his body moving in a 'puppet-like' way, as if controlled by an unseen force. 

In another case, one that left a deep impression on him, Lee said a girl from a Muslim family began convulsing and speaking in a male voice, declaring, 'I'm one of nine here… this is my house,' as pastors struggled to drive out what they believed was an entity. 

Reverend Chris Lee shared chilling exorcism causes, detailing how the experiences gave him a purpose since giving his life to God at the age of 24

Despite the intensity of these encounters, Lee said he does not feel afraid. Instead, he described feeling purposeful, and at times angry, at what he sees as an invasion of something sacred. 

'It's like a burglar in a house,' he said. 'Get out. You don't have this right.' 

For Lee, prayer and faith are not symbolic gestures but sources of authority, and he believes he is standing on the side of Christ in a spiritual battle he says is as real as any physical one.

His early spiritual awakening began after he abandoned a conventional life at age 21 and moved to Tanzania. 

'I was 24 when I was ordained, so I was one of the youngest in the Church of England at the time,' Lee said, explaining how quickly his calling took root. 

He left a career in property development, sold his house and moved into a remote Maasai region without electricity or running water. 

While his new home was far from a lap of luxury, it was where he knew he wanted to dedicate his life to the ministry. 

'It was there that I was able to ask big, profound questions of life, and it was there that I discovered my love for God, and felt His presence so much more in my life,' said Lee. 

He moved from England to Tanzania for mission work and within only a month, he performed his first exorcism (stock) 

When he asked his bishop if he could begin theological training, he was told to start almost immediately. 'He said, yes, you can start on Thursday,' Lee recalled, noting this moment marked the beginning of a long ministry in which he repeatedly confronted spiritual forces he believes are very real.

His first encounter came when he was in charge of students in Tanzania, and was called to see a student who was very ill. 

'I came into the room of this person, and I was expecting them to be lying down and being sick, but the person was screaming around the room and vomiting at the same time,' he said. 

The sight caught Lee completely off guard, as he was not witnessing a normal sickness. 

'I didn't have a spectrum of understanding of what was going on,' the reverend admitted. 'So in that moment I just prayed, "Lord, give me what I need to help this girl."'

After praying in the room, Lee contacted a German missionary who was in the area, hoping to get assistance. 

'When he arrived, just before we went in, I said, "Be aware, it's very disturbing. She's screaming, moving around the room, and vomiting,"' said Lee. 

'He said, "Okay, fine." We walked in, and she was suddenly completely normal. She was sitting up and talking. I was actually quite embarrassed. I thought, "What is going on?"'

He believes possession come after some kind of trauma that opens a dark door into the person's life, allowing demonic beings to take over 

The German missionary asked other students about the girl, who said she was someone afflicted by the demonic. 

Lee believes this was his first encounter with evil, but by no means his last. 

He recalled another chilling case that occurred while he was traveling to another church in the area, a church made of sticks. 

The bishop at the time was performing baptisms for the children, laying his hands on their heads for a blessing. 

'He was going along the line, laying his hands to bless the children,' said Lee. 'It was a teenage boy who suddenly leapt up into the sky just before the bishop was about to lay his hands on him.

'He started screaming, like a beast, like a lion, and then he ran into the wall.'

The boy was taken out of the church and placed on the ground with a blanket pulled over his head. 

As Lee and others approached quietly across the sand to pray, he said the boy began to tremble. Lee said the shaking intensified the closer they came, which he interpreted as a sign that whatever was afflicting the child was aware of their presence and reacting to it. 

'He picked up and ran away from us, screaming, into the woods. As he was running, it was very strange, because the way he moved was not like a normal person,' Lee said.

'It was as if he were one of those puppets on strings, his limbs were being used, but not in the correct way. 

'It was a very surreal experience, watching him flee in this almost puppeteered way, as if something inside him was controlling him, but not the way a normal human being would be controlled.'

The boy was brought back to the church, where the crowd surrounded him in prayer.

'I remember his eyes burning, with a real blackness, a darkness in his eyes, and we were commanding the spirit in him to leave, and he was growling, and barking at us,' the reverend recalled. 

Lee and the bishop laid their hands on the boy, commanding the demonic entity leave his small body, and in a moment, the child fell to the ground and began hyperventilating.

Then there was his experience with the young Muslim girl who would stay at his church.

 One day, the girl mysteriously fell to the floor and began shaking and screaming. 'What was interesting was that voices were speaking out of her,' Lee said. 

'The main voice was a male voice speaking in Swahili to the pastor who was leading the deliverance at that moment. 

'It said, "I'm one of nine here, and she's let us in." The language the demon used was, "This is my house. You have no claim over her. She's ours." 'We were saying, "No, in the name of Jesus, you need to get out."'

Another pastor came, telling Lee and the others to stop the exorcism. 

'He said she hadn't yet accepted Christ in her heart, and if we delivered her now, it could be made worse,' said Lee. 

'Biblically, he explained, if you clear the house, seven more can come back in unless the person has received Christ. His concern was that we might clear space for more to enter her. 

'So it was stopped in that moment. Her parents were informed, and they collected her. 

'My understanding is that she returned to school a few weeks later, which suggests her parents took her to a deliverance expert in Dar es Salaam or Morogoro, where I believe she was delivered. 

'She was an interesting case because she would come off the ground in violent surges, then stand up and contort, speaking in a male voice. That was one of the more severe cases.'

Lee suggested that these children may have suffered some kind of trauma in their lives, which opened a dark door for the demonic entities. 

'These experiences have made the realities of what I read in the Bible more real to me, the realities of the spiritual realm and the fact that we aren't just physical beings,' he explained. 

'We are spiritual beings, and our spirit is wrapped up in the physical. We are both of these things held as one.'

'The realities of darkness and light became more pronounced. In a world where we're struggling to seek and find truth, and where people say 'my truth' and 'your truth,' this cuts through that. It's quite clear: there is evil, there is good, there is truth, and there are lies.'

'I think it wakes you up to that reality, and it makes my faith more pronounced in myself. In a way, it strengthened my faith rather than wounded it.'

Lost tomb of the mysterious 'cloud people' unearthed after 1,400 years in 'discovery of the decade'

By STACY LIBERATORE, US SCIENCE & TECHNOLOGY EDITOR

It has been hailed as 'the most significant archaeological discovery in a decade.'

Archaeologists in Mexico have uncovered a 1,400-year-old tomb in the Central Valleys of Oaxaca that had been lost to history.

The stone structure, built by the Zapotec culture, known as Be'ena'a, or 'The Cloud People', is adorned with sculptures, murals and carved symbols that suggest ritual significance.

The Zapotec believed their ancestors descended from the clouds and that, in death, their souls returned to the heavens as spirits.

At the entrance sits a massive carved owl, its open beak revealing the face of a Zapotec lord, a symbol the National Institute of Anthropology and History said represented death and power.

The doorway is framed by a stone threshold and lintel, above which a frieze of engraved slabs displays ancient calendrical names.

Flanking the entrance are carved figures of a man and woman wearing headdresses and holding ritual objects, likely guardians of the tomb.

Inside the burial chamber, preserved sections of a vibrant mural remain intact, showing a procession of figures carrying bundles of copal as they move toward the tomb's entrance.

Mexico's president, Claudia Sheinbaum Pardo, said: 'It is the most important archaeological discovery of the last decade in Mexico due to its level of preservation and the information it provides.'

The Zapotecs have a history spanning over 2,500 years. 

They established a major pre-Columbian civilization centered at Monte Albán, which featured advanced agriculture and writing.

The Zapotec civilization mysteriously declined in the area around 900 AD.

However, the people did not completely disappear, as there are at least 400,000 living today.

Mexico's Secretary of Culture, Claudia Curiel de Icaza, said the 'exceptional discovery' of the tomb was due to its preservation. 

She added that it reveals how the Zapotec culture was a social organization with funerary rituals.

'It is a compelling example of Mexico's ancient grandeur, which is now being researched, protected, and shared with society,' she continued.

An interdisciplinary team from the INAH Oaxaca Center is currently working to conserve and protect the tomb, focusing on stabilizing the fragile mural painting. Experts say the mural’s condition is delicate due to root growth, insect activity, and sudden shifts in temperature and humidity.

At the same time, researchers are conducting ceramic, iconographic and epigraphic studies, along with physical anthropology analyses, to better understand the rituals, symbols and funerary practices connected to the tomb.

In 2024, archaeologists announced the discovery of tunnels that the ancient Zapotec civilization believed to be the 'entrance to the underworld' had been found beneath a centuries-old church.

Mitla, meaning place of the dead, was a city in southern Mexico known for its association with Pitao Bezelao, the Zapotec god of death.

But the Spanish arrived in the 16th Century and razed the city, building a church on the ruins of its most important temple.

A priest later wrote that 'the back door of hell' lay under the city – huge caverns believed to be the entrance to the Zapotec underworld.

But they were walled up, he said, and later excavations failed to find anything matching the scale of his description – until now.

Using non-invasive techniques, archaeologists recently revealed a series of chambers and tunnels beneath the city.

Five different sets of ruins were probed: the church group, the arroyo group, the adobe group, the south group, and the group of the columns.

Marco Vigato, founder of the ARX Project, which is leading the search, said: 'Some of the tunnels and chambers extend to a considerable depth, in excess of 50 feet.

The underground tunnels were revealed using a combination of ground penetrating radar, electric resistivity tomography, and seismic noise tomography. 

The first method uses radar waves to model the subsurface, while the second detects buried structures by measuring the flow of electricity through the earth.

Instead of electricity, the final method measures the speed at which seismic waves move through the ground.

Just how old the tunnels are is yet to be established.

'Natural caves in the area of Mitla have been occupied and partially modified by humans for thousands of years,' Vigato said:

'The earliest evidence of crop domestication in the area of Mitla dates back almost 10,000 years.

'There is no indication at the moment as to the possible age of the tunnels under the church or the other groups of structures at Mitla.

'They may have been created by the Zapotecs, or they could be much older.'

He added: 'The findings from the geophysical scans will have to be confirmed with archaeological methods.

'This could determine the nature of the cavities identified under the site and whether they contain any artifacts of archaeological significance.'

A military‑grade device capable of projecting a deafening, focused sound was deployed during a tense anti‑ICE protest in Minnesota Monday night.

State patrol troopers faced off with activists outside the SpringHill Suites in Maple Grove, where demonstrators believed federal immigration agents were staying.

Officers threatened to engage a long‑range acoustic device (LRAD), giving the crowd a countdown before deployment. 

The system, a highly directional loudspeaker, can emit piercing deterrent tones or amplified voice commands over long distances and was originally developed for military and crowd‑control use.

Experts warn that exposure to the device at close range can cause permanent hearing loss, ruptured eardrums, constant ringing in the ears, migraines, nausea, balance problems and even panic responses.

Marine Colonel Mark Cancian, a senior adviser for the Center for Strategic and International Studies, said, 'We used it in Iraq … if you're in the cone, it sounds like the voice of God is speaking to you.'

State patrol officials said they checked the device's volume, issued dispersal notices and did not actually use tones or sirens, despite reports circulating on social media.

The night ended with 26 arrests, whom the police said were allegedly taking part in 'unlawful assembly and riotous conduct.'

Minnesota police threatened protesters on Monday with a long‑range acoustic device (LRAD), giving the crowd a countdown before deployment

Monday's demonstration came on the heels of a shooting on Saturday.

Alex Pretti, 37, was killed shortly after 9am local time after an altercation involving multiple federal officers. 

The protest in the Minneapolis suburb came as federal law enforcement leadership in the state was in flux, with Border Patrol Commander Gregory Bovino and some agents expected to soon leave Minnesota after intense public scrutiny of recent actions by immigration authorities.

It was not immediately clear whether Bovino or other federal agents were staying at the hotel where demonstrators gathered. 

The department issued a statement saying: 'While we respect First Amendment rights, we will not tolerate property damage or violence in our community.'

The protest was declared unlawful after demonstrators caused property damage and engaged in violent behavior, which is not protected under the First Amendment. Officers deployed the LRAD after the crowd failed to comply with a dispersal order.

The military-grade loudspeaker can project spoken commands at intense volumes or emit piercing tones designed to get attention and deter movement. 

Even when only issuing voice commands, the device can be overwhelming.

'I think we saw that in the video there of the system, because it's so loud, I mean, it pushes you back,' Cancian told CBS News.

The system was developed as a non-lethal alternative to traditional crowd-control methods such as pepper spray, tear gas, and rubber bullets. 

'In some situations where you might end up using force, kinetic force, or even lethal force, you know this can avoid that and avoid permanent damage to people,' said Cancian. 

LRAD uses an array of high-frequency speakers to produce highly directional sound, concentrating audio into a narrow beam rather than dispersing it broadly.

This technology allows sound to travel long distances while maintaining clarity, so spoken messages or warning tones can be heard over ambient noise.

The LRAD system can switch between voice communication and a high-decibel deterrent tone, with volume and frequency precisely controlled by the operator.

The device is portable and can be mounted on vehicles, tripods or handheld platforms, and operators can adjust range, angle, and intensity depending on the situation.

It has been suggested that this is the same 'secret sonic' weapon President Donald Trump said US special forces used during the daring capture of the Venezuelan President Nicolas Maduro earlier this month.

Police did not active the system but used voice commands to deter the crowd

The night ended with 26 arrests, whom the police said were allegedly taking part in 'unlawful assembly and riotous conduct'

Trump bragged last week that 'nobody else' has it, while glorifying the capabilities of the US military.

The exact nature of the weapon and how it was used is unknown. Trump was coy when giving details during an interview with NewsNation anchor Katie Pavlich.

Pavlich asked Trump whether Americans should be 'afraid' of these sonic devices.

'Well, yeah,' Trump responded.

He then added that only the US military has access to the sonic weapons by noting, 'It's something I don't wanna… nobody else has it.'

'But we have weapons nobody else knows about.' Trump continued. 'And, I say it's probably good not to talk about it, but we have some amazing weapons.'

Following the capture of Maduro, reports surfaced that special forces used unknown sonic weapons to disable the Cuban bodyguards assigned to protect the Venezuelan dictator.

Press Secretary Karoline Leavitt took to X to share an interview with an unnamed security guard who claimed to be working the night the US struck Venezuela and took Maduro on drug trafficking charges.

'Stop what you are doing and read this,' she wrote, alongside five American flag emojis.

The interview saw the security guard reveal the terrifying capabilities of the mysterious new US military weapon, which he described as a 'very intense sound wave' that disabled Venezuelan forces. 

'Suddenly I felt like my head was exploding from the inside,' the security guard reportedly said. 'We all started bleeding from the nose. Some were vomiting blood. We fell to the ground, unable to move. 

'We couldn't even stand up after that sonic weapon or whatever it was.' 

The security guard claimed moments before the raid that snatched Maduro, 'all our radar systems shut down without any explanation.' Then eight helicopters arrived and around 20 soldiers descended.

'They didn't look like anything we've fought against before,' the guard claimed.
