Astronomer’s at NASA discovered a supermassive black hole that has a Death Star-like jet shooting out at the core of a huge galaxy and it appears that stars along the beam’s trajectory are exploding.

"We don't know what's going on, but it's just a very exciting finding," said Alec Lessing of Stanford University, lead author of the paper published in The Astrophysical Journal. "This means there's something missing from our understanding of how black hole jets interact with their surroundings."

Stars are exploding but not destroyed

The stars that are exploding along the trajectory of the giant blowtorch-like beam are called novae.

The Hubble found that twice as many novae near the beam of plasma are exploding twice as much as compared to anywhere else in the galaxy during the surveyed time period.

These stars typically erupt in a double-star system where an aging star begins to spill hydrogen into a burned out white dwarf star companion, NASA explained. 

When the dwarf star has its fill of hydrogen, it explodes like a giant nuclear bomb. But the dwarf is not destroyed in this process, it simply starts this cycle over again.

While it has been theorized that the heat from the jet is leading to the novae explosions, researchers said it is not nearly hot enough in the observed locations to have this type of impact on the stars.

Researchers are still trying to figure out what’s going on.

"There's something that the jet is doing to the star systems that wander into the surrounding  neighborhood. Maybe the jet somehow snowplows hydrogen fuel onto the white dwarfs, causing them to erupt more frequently," said Lessing. "But it's not clear that it's a physical pushing. It could be the effect of the pressure of the light emanating from the jet. When you deliver hydrogen faster, you get eruptions faster. Something might be doubling the mass transfer rate onto the white dwarfs near the jet."

What is the jet of light?

The jet is being shot out by a 6.5 billion-solar-mass central black hole which is engorged with infalling matter, NASA said.

The black hole is launching a 3,000-light-year-long jet of plasma that is blazing through space nearly at the speed of light.

Anything that is caught directly, or near, the jet "would be sizzled."

NASA engineers have successfully reactivated a set of thrusters on Voyager 1, unused for decades, to keep the 47-year-old spacecraft communicating with Earth. With the probe billions of miles from our planet, this maneuver was critical to ensuring it stays on course. The aging spacecraft continues to surprise with its resilience.

Voyager 1, launched in 1977, has far exceeded its expected lifespan, continuing to transmit data from interstellar space. Currently about 15 billion miles from Earth, the probe travels beyond the heliosphere, the Sun’s protective bubble of magnetic fields. As its components age, new challenges arise, requiring NASA engineers to find creative solutions to keep the mission alive. One such challenge emerged this year when the spacecraft’s thrusters started clogging, threatening its ability to communicate.

Turkey Kumburgaz UFO Videos Are 100% Real With Clear View Of Alien Entities Sitting Inside Craft

A series of UFO incidents occurred between 2007 and 2009 in the town of Kumburgaz, situated near Istanbul, Turkey. The events stunned the media and UFO enthusiasts after the images and  videos of the sightings went viral on the Internet. The  video evidence of UFOs shared by a nightwatchman named Yalcin Yalman could be another strong evidence of non-human technology.

Back in 2008, Yalcin Yalman worked as a night watchman at the Yenikent facility from where he shot all these amazing videos of UFOs, hovering over the Marmara Sea near Kumburgaz. He even showed his second-hand camera to the media in a press conference held at the Dedeman Hotel in Istanbul.

Yalman said he started recording the strange crafts as a hobby to pass his time in the night. Due to the shaky videos, some skeptics claimed that the mysterious objects over the skies of Turkey could have been a US stealth drone or other aircraft. However, numerous experts confirmed that the videos were authentic. Besides, many people witnessed the same unknown crafts in the sky. The sightings gained attention from locals, national media, and even CNN. Several videos were recorded between June 8 and 12, 2009, showing mysterious objects and lights.

Originally, the video was analyzed and made public by the Sirius UFO Space Sciences Research Center led by researcher Haktan Akdoğan. Haktan said the UFOs were often seen by civilians and military pilots during an International UFO Congress in 2009. (Source)

In 2009, after the conference, there were witnesses of 8-10 people including UFOlogist Dr. Roger Leir, who also witnessed and verified the Kumburgaz UFO sighting. Dr. Leir was present during the filming of one video on May 17, 2009, and confirmed that as the UAP turned, it was similar to the “Roswell” shaped craft (more boomerang-shaped) rather than a traditional disc. Dr. Leir discussed this incident that happened with him after the conference on Coast to Coast with George Knapp.

Dr. Leir told Knapp that he, Yalman and others went to Kumburgaz to film UFOs. The group stayed up from midnight to 4 o’clock in the morning to capture any possible sightings. The conditions were ideal, with clear skies and no obstructions. During the filming, they observed a bright object below the full moon, which initially appeared as a potential star or planet. As they focused on this object, they discovered a semi-circular craft with a multitude of lights, possibly shaped like a boomerang or a cylindrical saucer.

Dr. Leir said, 

“You’d think, ‘Well, gee, a bright sky, bright moon, you’re not going to see anything.’ But in this case, the moon was a big help. It essentially lit up the exterior portion of the craft, which initially, when we saw it, looked a bit like a boomerang because we weren’t seeing it straight on, so we couldn’t tell the exact shape of the craft. But then we went to full film on it, and we could see that it was either a boomerang, or we were looking at a certain portion of a cylindrical craft or a saucer.

Till this day, I don’t know, and I don’t know what the analysts said about the shape. But it was either one of the two: either a boomerang shape with a round front or a complete saucer. It did turn a couple of times, so we were able to see the side, and it looked like it could have been saucer-shaped. But then we got the biggest shock of our lives because we could see light that was emanating from the internal portion of the craft in three areas. One was directly in front, and one was on either side.

This was a full-on front view, and folks can look at the Coast website and they can not only see the  video but please go to the Chilean analysis because there are some still photos there which show what we saw when we looked in the central portion. That was a big shock to look and see, not a Rorschach-type thing, but actual entities that were, whatever they were doing, looking out the front of the craft, just the same as we were looking at them.”

Video Observation

From 2007 to 2009, Yalman recorded approximately 30  videos. The footage was taken with a MiniDV Canon DM-GR1-A based on the NTSC system with a diaphragm set at a maximum of 1.8. It is a 3CCD 20x optic 100x with a teleconverter mounted on a 58 mm adapter. The tele-objective is a Sony VCL HGD 1758 model lens, x 1.7. [2007 to 2009 Original Raw Footage]

The videos were examined by two influential state-sponsored organizations in Turkey, “The Scientific and Technology Research Board of Turkey” and “The TUG National Observatory.” Their objective was to identify any evidence of forgery, but the results supported the authenticity of the videos. The original film cassettes were also studied by individuals from Japan, Chile, Brazil, and Russia, and despite several attempts, no one has been able to conclusively demonstrate evidence of a hoax, fraud, or manipulation, leaving the case unidentified.

Yalman’s camera was equipped with a zoom option which allowed him to even capture the pilots, sitting in one of the crafts. The image is shaky due to the hand movements while zooming. However, with the editing software, the video was stabilized, and the result shocked everyone. Two humanoid figures could be seen in the image with large black eyes and oversized heads.

Haktan Akdoğan noted that these are the most important images in Turkey and in the world, saying: “After doing all the necessary analysis which went on for several weeks, the board came to a definite conclusion with no doubt that these are 100% genuine videos. The objects sighted in the aforementioned footage that have a structure that is made of specific material are definitely not made up by any kind of computer animation nor are they any form of special effects used for simulation in a studio or for a video effect therefore in conclusion it was decided that the sightings were neither a mock up or hoax. It is concluded that these objects in the sightings that have physical and material structures do not belong in any category such as; planes, helicopters, meteors, Venus, Mars, satellites, fireballs, Chinese lanterns, fireballs, weather balloons, natural or atmospheric phenomenon etc. and but rather fall into the category of UFOs.”

“We see the heads of not only one UFO but also of two beings in the images. This is the first in the world.” He further added that those images would have a great impact on UFOlogy. He had been researching UFOs for 22 years and had never seen something like this. He stated: “These are the most remarkable images taken in Turkish history.”

[In translation] Akdoğan stated that “these beings are generally seen in areas rich with resources, volcanic areas, and historical places. They started to come more frequently after nuclear tests. Maybe the released radiation also harms the cosmic neighbors, we disrupt the balance in the universe. Maybe they observe this dangerous process.” (Source)

According to the report issued by the Scientific and Technology Research Board of Turkey, the examination of these frames has yielded the following results:

• The images were recorded in digital NTSC format by the above-mentioned camera.
• The date on the  video indicates that the recordings were made during 2007, 2008, and 2009.
• The footage images of the object that visibly have a certain configuration are not computer animations, special video effects or studio-re-created images or models. The footage is genuine.
• The first observation made from the footage is that some of the images were recorded in the nighttime sky at a certain altitude from the horizon. The footage also covers images of the moon in some parts which proves that the video was shot in the nighttime and open air. But, the fact that digital date displays show AM in certain frames and PM in others, raises suspicion about the validity of the time in which the recordings were made.
• Since in some parts, there is no other object that can be featured as a reference in the close-up frames and no observable differences were found on background examination, the actual location, distance, dimensions and nature of the objects could not have been determined.
• Through the examination of shootings of multiple dates, it is a strong possibility that 2-3 different objects were captured. However, it is difficult to determine whether the objects are moving or not. Their movement is slow even if they do so.
• The reflections of light on the objects are sometimes caused by the moon which was in a convenient location at that time, and sometimes produced by some other sources of light.
• The light reflection from the left side of the object which is seen on the August 10th shootings is not produced by the moon. At that time, the moon was in a phase that was pretty close to the “new moon” phase and located approximately at a 10-degree proximity/angle to the horizon. Moreover, the image processing analysis conducted on some parts of the footage revealed that the center of the object has the same density as its background, namely is of a transparent nature.

Not Debunked

Adam Goldstack of UAP Media UK mentions that many debunkers try to explain the craft as cruise ships but according to former F-16 fighter pilot and researcher Chris Letho, it does not add up. Letho analyzed the  videos and case and calculated the object’s size, horizon distance, plus visual angles from the Marmara Sea. He concluded the logistics of a cruise ship did not match the reported UAP. (Source)

Additionally, the triangulation of the UAP in most video cases was calculated to be too high to be a cruise ship or boat, by other researchers. Alternatively, in the fixed/stabilized camera videos (as shown below), we can see that the objects are motionless against a black background in the vast majority of videos. The motionless aspect of the UAP could also discount the “small-boat theory,” given that even on calm waters/oceans floating objects will still move and rock around slightly. Additionally, despite the mass mainstream media coverage in Turkey at the time, no person has ever come forward to state that the objects/boats belonged to them or that they were sailing off the coast in the middle of the night.

Goldstack writes, “From an analytical perspective, the Turkey Kumburgaz UFO case is unique with regards to the clear and multiple  video footage obtained. Through this case, we also have sequential data that display behavioral patterns, times, and dates. We see all of the twenty-five video encounters/incidents at night-time/early morning (with one in the late evening), which is in keeping with the wider range of Ufology data that suggests UAP often appears at night-time.

We also see another significant pattern displaying the encounters around water – in this case, the Marmara Sea. The Sea of Marmara itself is a small sea with an area of 11,350 km2 (4,380 sq mi) and with dimensions of 280 km × 80 km (174 mi × 50 mi). The sea has a greatest depth of 1,370 m (4,490 ft). How significant the Sea of Marmara is to potential UAP has still not been explained. No connection to nuclear facilities or weapons has been linked in this case.”

Unveiling the Truth: The Roswell Alien Autopsy – Fact or Fiction?

The Roswell Incident of 1947 remains one of the most enduring mysteries in UFO lore. Central to this enigma is the so-called alien autopsy footage that captivated millions across the globe with its shocking images of extraterrestrial bodies. For decades, conspiracy theorists, skeptics, and believers have debated the authenticity of the footage, sparking curiosity, research, and government scrutiny. However, in recent years, new revelations and leaked documents have re-opened the debate about whether the footage is genuine or a sophisticated hoax.

A Brief History of the Roswell Incident

On July 8, 1947, headlines around the world reported the discovery of a “flying disc” in Roswell, New Mexico. Initial excitement quickly turned into speculation as the U.S. military retracted their statement, claiming the debris was merely from a weather balloon. This sudden shift in narrative only fueled suspicion, leading to numerous theories that the military had found and was covering up evidence of an extraterrestrial crash.

Years later, in 1995, the so-called alien autopsy footage was released to the public by British entrepreneur Ray Santilli. The grainy black-and-white footage appeared to show an autopsy being performed on an alien body, presumably from the Roswell crash. The footage reignited global interest in UFOs, and the debate over its authenticity has never truly subsided.

The Controversy Surrounding the Footage

For years, Ray Santilli adamantly defended the authenticity of the alien autopsy footage. According to Santilli, the film was genuine but had deteriorated over time. As a result, he claimed that some sections of the footage were “restored,” adding layers of confusion about its credibility. In 2006, Santilli admitted that much of the footage was a recreation based on the degraded original film, though he maintained that key elements were authentic.

This admission raised more questions than it answered. Why would there be two versions of the autopsy footage? If Santilli’s restoration was akin to restoring a historical painting, why were two films necessary? Skeptics quickly jumped on these inconsistencies, questioning whether the entire film was a fabricated hoax designed to capitalize on the public’s fascination with UFOs.

The Role of UFO Researchers and Skeptics

Even in the face of mounting skepticism, some researchers and believers remained convinced that there was more to the Roswell incident than met the eye. UFO researcher Philip Mantle, who had long investigated the alien autopsy footage, pointed out that despite claims of a hoax, many details surrounding the film still remain unexplained. According to Mantle, efforts to debunk the footage, including investigations by major television networks, had not definitively disproven its authenticity.

On the other hand, critics of the alien autopsy film pointed out the discrepancies in Santilli’s story over the years. As more inconsistencies emerged, particularly in relation to Santilli’s handling of the film’s authenticity, doubts increased. Kodak, the company whose film stock was allegedly used, offered to analyze the footage to verify its age, but Santilli never followed through. This further fueled the narrative that the footage was likely a hoax, driven by financial gain.

Government Involvement and the UFO Community

An additional layer to the Roswell story involves government secrecy. The U.S. military’s changing explanations for the crash have led many to believe that a cover-up has been in place since 1947. Initially described as a flying disc, the object was later dismissed as a weather balloon, and then as part of a top-secret project known as “Project Mogul.” This inconsistency has only strengthened suspicions among UFO researchers that the truth about Roswell has yet to be fully revealed.

The release of the alien autopsy footage in the 1990s further complicated matters. Researchers like Robert Bigelow, an American businessman and long-time advocate of UFO research, became deeply involved in examining the film. His organization, the National Institute for Discovery Sciences, conducted studies and employed scientists to investigate the UFO phenomenon, though no definitive conclusion about the alien autopsy footage was reached.

Despite the many doubts about the footage’s authenticity, some believers insist that Santilli’s film contains at least some elements of truth. They argue that if the footage were entirely fake, why have there been so many efforts to discredit it? Supporters of Santilli’s claims point to incidents like the mysterious burglary of his office as evidence that shadowy forces were at work to suppress the truth.

Impact on Popular Culture and the Ongoing Debate

Regardless of its authenticity, the alien autopsy footage has become a staple of popular culture. It has appeared in episodes of The X-Files, The Simpsons, and Seinfeld, and has even been recreated in museums around the world. The footage’s impact on the public’s perception of UFOs has been profound, raising awareness and interest in UFO phenomena across generations.

Interestingly, while the autopsy film itself remains in question, it has not damaged the credibility of the broader Roswell story. If anything, the film has kept the incident alive in public consciousness. Even as skeptics dismiss the footage as a hoax, the core mystery of what happened at Roswell in 1947 remains unsolved.

The alien autopsy footage continues to fascinate, provoke debate, and fuel conspiracy theories. The footage’s origin may be in dispute, but one thing is clear: it has become an inseparable part of the Roswell mythos. As new leaks and documents emerge, the truth behind the alien autopsy may one day come to light, though for now, the mystery lingers.

In the end, whether the footage is real or fake, the allure of the unknown continues to capture the imagination. The Roswell Incident remains one of the most compelling UFO mysteries in history, and the alien autopsy footage—whether a clever hoax or a glimpse into extraterrestrial life—will undoubtedly remain part of that legacy for years to come.

Een nieuwe studie werpt licht op het intrigerende mysterie van Mars’ ontbrekende atmosfeer. Want mogelijk verbergt die zich wel vol in het zicht…

Mars was niet altijd de kille woestijn die we nu kennen. Er zijn steeds meer aanwijzingen dat er miljarden jaren geleden water over het oppervlak van de rode planeet stroomde. En als er water was, dan moet er ook een dikke atmosfeer zijn geweest om te voorkomen dat het bevroor. Maar zo’n 3,5 miljard jaar geleden droogde het water op en de lucht, die ooit vol koolstofdioxide zat, werd aanzienlijk dunner. Hierdoor wordt onze naaste buur nu nog slechts omhuld door een flinterdunne atmosfeer. Een vraag waar wetenschappers zich al jaren het hoofd over breken, is wat er precies met de Martiaanse atmosfeer is gebeurd. Twee geologen komen nu in het vakblad Science Advances met een verrassende theorie.

Klei
Volgens de twee geologen zou het antwoord mogelijk te vinden kunnen zijn in de klei van de planeet. In hun artikel suggereren ze dat een aanzienlijk deel van de verloren atmosfeer van Mars mogelijk is opgeslagen in de kleiachtige korst. Ze stellen dat het vloeibare water dat ooit zo rijkelijk over Mars stroomde, door bepaalde soorten gesteente had kunnen sijpelen, wat een langzame kettingreactie zou hebben opgestart. Deze reactie zou geleidelijk koolstofdioxide uit de atmosfeer hebben onttrokken en omgezet in methaan — een vorm van koolstof die gedurende lange tijd in de klei van de planeet kan worden opgeslagen.

Aarde
Deze theorie is niet eens zo vergezocht. Vergelijkbare processen komen namelijk ook voor in bepaalde gebieden op aarde. De onderzoekers hebben dan ook hun kennis van de interacties tussen gesteenten en gassen op aarde gebruikt om te begrijpen hoe soortgelijke processen op Mars zouden kunnen werken. Ze ontdekten dat, rekening houdend met de geschatte hoeveelheid klei die het oppervlak van Mars bedekt, deze klei tot 1,7 bar koolstofdioxide zou kunnen vasthouden. Dit zou ongeveer 80 procent van de oorspronkelijke atmosfeer van de planeet vertegenwoordigen.

Deze afbeelding toont de geleidelijke verandering van ijzerrijke rotsen op Mars wanneer deze in contact komen met water dat CO2 uit de atmosfeer bevat. In de loop van miljarden jaren zou dit proces voldoende CO2 in de kleilaag hebben kunnen opslaan, in de vorm van methaan, om het grootste deel van het CO2 te verklaren dat uit de vroege atmosfeer van de planeet is verdwenen.

Smectiet
Concreet zou de Martiaanse atmosfeer weleens opgegaan kunnen zijn in een soort oppervlakte-klei mineraal genaamd smectiet, dat bekend staat als een zeer efficiënte opslagplaats voor koolstof. In een enkele korrel smectiet zitten talloze ‘plooien’ waarin koolstof miljarden jaren lang ongestoord kan blijven. De onderzoekers hebben aangetoond dat de aanwezigheid van smectiet op aarde waarschijnlijk het resultaat is van tektonische activiteit. Zodra het aan het oppervlak kwam, konden de kleimineralen genoeg koolstofdioxide uit de atmosfeer opnemen en opslaan, waardoor de planeet gedurende miljoenen jaren afkoelde. Ook Mars blijkt bedekt te zijn met dezelfde smectiet-klei. De onderzoekers vroegen zich daarom af of deze klei op Mars een vergelijkbare functie zou kunnen hebben gehad in het vasthouden van koolstof. En als dat het geval is, hoeveel koolstof zou de klei dan kunnen opslaan?

Smectiet-klei op Mars
Zoals je hierboven kunt lezen, ontstaat smectiet op aarde door de beweging van continentale platen en het naar boven brengen van rotsen uit de mantel. Mars kent echter geen soortgelijke tektonische activiteit. Hoe het kan dat Mars dan toch bedekt is met smectiet-klei? In de loop van ongeveer een miljard jaar zou het water dat door de korst sijpelde geleidelijk reageren met olivijn. Wetenschappers denken dat de Martiaanse korst voornamelijk uit stollingsgesteente bestaat dat rijk is aan olivijn, een mineraal dat een gereduceerde vorm van ijzer bevat. Zuurstofmoleculen in het water zouden zich aan het ijzer hechten, waardoor waterstof vrijkomt en het rode geoxideerde ijzer ontstaat dat de planeet zijn herkenbare kleur geeft. Deze vrijgekomen waterstof zou vervolgens met koolstofdioxide in het water hebben gereageerd om methaan te vormen. Naarmate deze reactie in de loop van de tijd vorderde, zou olivijn langzaam zijn omgevormd tot een ander soort ijzerrijk gesteente, bekend als serpentijn, dat daarna bleef reageren met water om smectiet te vormen.

Na een rekensommetje kwamen de onderzoekers tot een interessante ontdekking. Als Mars bedekt is met een laag smectiet van 1.100 meter diep, zou deze hoeveelheid klei in staat zijn om een enorme hoeveelheid methaan op te slaan. Dit zou overeenkomen met het merendeel van het koolstofdioxide in de atmosfeer dat sinds het opdrogen van de planeet verloren is gegaan. “We constateren dat de schattingen van de wereldwijde klei-volumes op Mars overeenkomen met een groot deel van de oorspronkelijke CO2 van de planeet, dat is vastgelegd als organische verbindingen in de kleirijke korst,” zegt onderzoeker Joshua Murray. “In zekere zin zou de ontbrekende atmosfeer van Mars zich weleens in het volle zicht kunnen verbergen.”

Kortom, de onderzoekers hypothetiseren dat de verloren koolstofdioxide mogelijk is opgeslagen in de kleiachtige oppervlakken van Mars. “Mogelijk hebben zich dus op de aarde en Mars soortgelijke processen voorgedaan,” denkt onderzoeker Oliver Jagoutz. “Grote hoeveelheden atmosferisch CO2 zouden kunnen zijn omgezet in methaan en in de klei zijn opgeslagen.” Deze ontdekking is niet alleen belangrijk voor de wetenschap van Mars, maar heeft ook implicaties voor toekomstige missies naar de planeet. Zo suggereren de onderzoekers dat deze opgeslagen Martiaanse koolstof op een dag weer kan worden teruggewonnen en omgezet in brandstof. “Mogelijk is er nog steeds methaan aanwezig,” stelt Jagoutz. “Dit zou in de toekomst als energiebron op Mars kunnen worden gebruikt.”

The brains of NASA's Europa Clipper spacecraft are stored in a metal vault.

It's where the large exploration vehicle — the length of a basketball court — safeguards its computers, software, and many electronics. The craft is about to launch to Jupiter's moon Europa, a world planetary scientists suspect harbors an ocean twice the volume of Earth's. With around 50 close swoops by Europa, NASA will be able to confidently answer the question of whether this ocean realm also hosts the ingredients, such as an energy source and telltale materials, to support life.

Credit: NASA / JPL-Caltech

Yet the radiation environs there are particularly harsh.

"The charged particle environment at Europa's location is immense," Cynthia Phillips, a NASA planetary geologist and project staff scientist for the space agency's Europa Clipper mission, told Mashable.

Jupiter, a gas giant planet 317 times more massive than Earth, generates a massive magnetic field shooting out between 600,000 to 2 million miles (1 to 3 million kilometers) toward the sun. It's created by the planet's liquid metal core, which spins and creates electrical currents (moving electric charges make magnetic fields). Crucially, this magnetic field grabs and then accelerates particles from the relentless solar wind — a stream of rapidly traveling charged particles emitted by the sun — which creates potent radiation belts around Jupiter.

"It bombards everything."

Any craft traveling around the planet will almost certainly pass through these hazardous zones and expose instruments to harmful particles, which can damage computer chips and electronics. "It bombards everything," Curt Niebur, Europa Clipper's program scientist, said at a press conference leading up to the mission's launch. Decades ago, during the Voyager mission, NASA's engineers were worried about the craft passing by Jupiter. A person hypothetically riding aboard Voyager as it passed Jupiter would have gotten hit with a radiation dose 1,000 times the lethal level.

A depiction of Jupiter's sprawling magnetic field. If was visible to the naked eye, "it would appear two to three times the size of the sun or moon to viewers on Earth," NASA explained.

Hence, the vault. "The vault seriously reduces the harmful radiation these electronics get," Phillips said. (NASA's Juno craft, exploring the greater Jupiter system, also carries a vault.)

Yet there are electronics outside this protective metallic box. And in May NASA received test data that suggested some transistors — which are electrical switches that control how electricity flows around the spacecraft — couldn't withstand the high radiation environs around Europa. Fortunately, intensive follow-up testing showed these switches will work as the craft makes some 50 flybys over three and a half years. "They unequivocally passed that review today," Nicola Fox, who heads NASA's Science Mission Directorate, said following a pivotal September decision to green-light the mission.

But mission engineers will be watching these transistors closely. As the New York Times reported, NASA bolted a late add-on to the craft, a small "canary box" holding the different types of transistors. If any show signs of damage or dysfunction as Europa Clipper swoops through belts of radiation, planners could adapt the mission.

In this graphic, the box illuminated in red shows the Europa Clipper's vault on the center of the spacecraft.

Already, the mission's orbital plan — which is to zip away from damaging regions after making close flybys of the ice-covered moon — minimizes the time the craft is exposed to high radiation zones. During each orbit around Jupiter, the craft will spend under a day in an irradiated zone, before swooping out. It won't return for between two to three weeks.

"You get out of there," Phillips told Mashable.

"You get out of there."

The robotic spacecraft's exposure to radiation, however, comes with rewards. When the probe dips close to Europa between 2031 and 2034, it will have the chance to view, scan, and investigate Europa in unprecedented detail. A ground-penetrating radar will look under the ice, and potentially see areas of liquid water or even where the ice meets the alien ocean. An instrument called the SUrface Dust Analyzer, or SUDA, will literally sample particles of Europa that have been ejected into space by tiny meteorites. And, of course, Europa Clipper will capture a bounty of images.

"The images are going to be spectacular," said Laurie Leshin, director of NASA’s Jet Propulsion Laboratory, the agency center that built the craft.

In sum, with this orbiting laboratory of instruments, NASA will be able to determine if the ocean moon has the right stuff — energy sources, a long-lived stable ocean, organic compounds (like carbon) — for life. If so, the agency plans to return to Europa and land on the icy crust. This time, they won't just be looking to see if it's habitable. They'll drill into the ice, looking to see if it's inhabited.

"We'll be knocking on the door for a second mission," Niebur said.

Experts reveal alarming theory for why UFOs appear to defy the laws of physics - and what we look like to them

• READ MORE:  Ex-Pentagon official claims US has recovered alien bodies

By Noa Halff For Dailymail.Com

Experts have theorized that UFOs appear to defy the laws of physics potentially thanks to an anti-gravity machine, and that as a result, humans look like we're moving in slow-motion.

Luis Elizondo, the former Pentagon insider who's been blowing the lid off the government's UFO secrets, has made shocking claims in his book, 'Imminent: Inside the Pentagon's Hunt for UFOs.'

In his bombshell memoir, he outlines a theory that gained steam during his time as part of the AATIP (Advanced Aerospace Threat Identification Program) group: UFOs harness anti-gravity to circumvent the laws of physics.

An anti-gravity device, forming what Elizondo's team calls a 'bubble' around a craft, would potentially make the object immune to Earth's gravitational forces - which might explain its incredible acceleration abilities.

And without any gravity affecting the craft, there would also be no time dilation taking place, meaning that while time for everyone on Earth would be slowed down by the Earth's gravity, time for anything operating a craft would be considerably faster.

This would mean anything looking outside a craft would see the entirety of humanity moving at a fraction of their speed.

Research by Sean Kirkpatrick, director of the Pentagon's All-domain Anomaly Resolution Office, and Harvard's Avi Loeb has shocked the scientific community when they concluded that recent UAP (Unidentified Aerial Phenomena) observations defy laws of physics

Physicist Erik Lentz from the University of Göttingen has similarly proposed a mind-boggling theory that could explain how these otherworldly visitors traverse the vast distances of space.

His research suggests a way to create the above mentioned 'warp bubble' that could allow spacecraft to travel faster than light without breaking Einstein's cosmic speed limit, as reported by Physics World. 

But the catch is that it would require energy equivalent to 'hundreds of times the mass of the planet Jupiter'

'A warp bubble traveling faster than light cannot be created from inside the bubble, as the leading edge of the bubble would be beyond the reach of a spaceship sitting at its center,' he said.

'The problem is that you need energy to deform space all the way to the very edge of the bubble, and the ship simply can't put it there.'

Erik Lentz suggests a 'warp bubble' could allow spacecraft to travel faster than light without breaking Einstein's cosmic speed limit

Meanwhile, a groundbreaking paper by Sean Kirkpatrick, director of the Pentagon's All-domain Anomaly Resolution Office, and Harvard's Avi Loeb also sheds light - or bends it - on how UFO seem to create optical illusions.

The paper states that these mysterious objects should create 'a bright optical fireball, ionization shell and tail' due to friction with air or water, as reported by Popular Mechanics. 

'The friction of UAP with the surrounding air or water is expected to generate a bright optical fireball, ionization shell and tail — implying radio signatures,' it wrote.   

On top of that, many of the observed UAPs show no signs of these telltale signatures.

This could mean that UFOs could be nothing more than 'sensor-induced optical illusions.' 

'The lack of all these signatures could imply inaccurate distance measurements (and hence derived velocity) for single site sensors without a range gate capability,' the authors wrote. 

'Typical UAP sightings are too far away to get a highly resolved image of the object and determination of the object's motion is limited by the lack of range data.'

Without any gravity affecting the craft, there would also be no time dilation taking place, meaning that while time for everyone on Earth would be slowed down by the Earth's gravity, time for anything operating a craft would be considerably faster

However, Elizondo points out in his book that the optical illusion could be generated by the 'bubble'.

Citing the Doppler effect, the former intelligence officer said that light moving in and out of the medium would skew based on if the object was moving away from you or toward you. 

Elizondo, risking his life, has alleged in his book that the US military has been running a top-secret program to retrieve and reverse-engineer alien craft for years.

He even has claimed they've recovered non-human specimens.

'We're not alone,' Elizondo told NewsNation. 'We are not alone in this universe, and it is a simple fact. The U.S. government has been aware of that fact for decades now. I think if the American public knew just how deep this lie went, that we would have a very significant constitutional crisis on our hands.'

• Ex-Pentagon official claims US has recovered alien bodies 

His book contains, among its many incredible revelations, details on a 2016 plan hatched by Elizondo and his military colleagues to catch a UFO in the ocean.

'The United States has been involved in the recovery of objects,' Elizondo told the outlet. 'Vehicles of unknown origin that are neither from our country or any other foreign country that we're aware of.'  

But it's not just conspiracy theories anymore.

In August, Elizondo told reporters that he can confirm one of two 'vehicles of unknown origin' were recovered from the now legendary Roswell UFO crash of 1947.

More shocking still, Elizondo said, 'We, as a nation have, been interested in not only the vehicles themselves but the occupants,' which he called 'biological specimens.'

Elizondo helped release three of the most famous UFO videos in history after leaving his role in the US Department of Defense in late 2017. 

Elizondo first rose to national prominence in late 2017 in the pages of the New York Times — where he blew the whistle on the US military and intelligence community's pervasive mismanagement and excessive secrecy on the topic of UFOs.

His public resignation and opaque role within the Pentagon's UFO-hunting portfolio, known to its Senate backers as the Advanced Aerospace Threat Identification Program (AATIP), brought fame and a lead role in a History channel docu-series.

In April 2020, the Pentagon officially released three videos that Elizondo had helped leak in 2017, each taken by US Navy fighter pilots who had reportedly witnessed 'unexplained aerial phenomena' (UAP) as UFOs are now more technically known.

Official US Navy video shows 'UFO' tracked off East Coast in 2015

Elizondo first rose to national prominence in 2017 in the pages of the New York Times, after he helped release three US Navy infrared UFO videos - including the GOFAST video (above)

The videos depict, as Elizondo told CNN, 'things that don't have any obvious flight surfaces, any obvious forms of propulsion [...] maneuvering in ways that include extreme maneuverability beyond, I would submit, the healthy G-forces of a human or anything biological.'

Despite corroboration from his peers and the late Senate Majority leader who helped create AATIP, Nevada Democrat Harry Reid, the Department of Defense has maintained that Elizondo's military role had no official UFO-hunting duties.

Pentagon officials denied the existence of any 'credible evidence of extraterrestrial activity,' in a statement responding to NewsNation's forthcoming interview.

'As we have stated previously, Luis Elizondo had no assigned responsibilities for the Advanced Aerospace Threat Identification Program (AATIP) while assigned to the Office of the Under Secretary of Defense for Intelligence and Security,' DoD spokesperson Sue Gough told NewsNation.

Critics of Gough have pointed to a 2003 research paper on psychological warfare that she wrote for the US Army War College, implying the Pentagon spokesperson might be part of a coordinated campaign to undermine Elizondo's credibility.

And, in May 2021, Elizondo filed a 64-page complaint to the DoD's Office of the Inspector General accusing high-ranking military officials of attempting to silence him by threatening his security clearances and obfuscating of his work with AATIP.

Elizondo said he endured 'malicious activities, coordinated disinformation, professional misconduct, whistleblower reprisal and explicit threats perpetrated by certain senior-level Pentagon officials.'

Above, veteran Australian TV news broadcaster and investigative reporter Ross Coulthart - who conducted the first televised interview with government UFO whistleblower David Grusch last year - conducted the new interview with Elizondo, which airs in full on Friday

Former intelligence agent spills secrets from Pentagon's UFO program

These actions, he and his attorneys said, suggested 'a coordinated effort to obfuscate the truth from the American people, while impugning my reputation as a former intelligence officer at the Pentagon.'

His new memoir, 'Imminent,' sees the former Pentagon official opening up about much more incredible personal accounts — including the story of his own family's disturbing experience with 'green orbs' floating through their house.

In the book, Elizondo also details he and another AATIP member's plan to catch UFOs on the high seas.

He told Dailymail.com in August that their investigations pointed to these craft having an apparent interest in military operations, nuclear power, and were often seen around bodies of water.

So they coordinated with the Navy and other branches to create 'Project Interloper': an attempt to lure the mysterious craft and record them with high-tech equipment.

New Map Reveals Impressive Megastructures in Local Universe

The newly-developed map of the local Universe is based on the motions of 56,000 galaxies, according to a team of astrophysicists from the Leibniz Institute for Astrophysics Potsdam.

This map shows the distribution of matter in the local Universe; it shows how matter flows, i.e. along which trajectories (thin lines) the galaxies move.

Image credit: Valade et al., doi: 10.1038/s41550-024-02370-0.

“Mapping the Universe has always been one of the most challenging tasks in astronomy,” said lead author Dr. Aurelien Valade and colleagues.

“Inaccurate observations, observational errors and incomplete data make this work extremely difficult.”

“In addition, the observed galaxies make up only a small part of the total mass in the Universe, as much of the matter exists in the form of invisible dark matter.”

“Furthermore, galaxies are not bound to be formed in such a way that they accurately trace the underlying matter well, which makes them an uncertain indicator of the matter distribution in the Universe.”

“Therefore, in order to create a map of our cosmic environment, we also look at the motion of galaxies.”

“On the one hand, galaxies move away from us with the expansion of the Universe, but on the other hand they also attract each other due to gravity.”

“These movements can be mapped and reveal the cosmic currents — the rivers and gulf-streams throughout the cosmos on which galaxies move.”

“Since the motion is caused by gravity, it can thus be used to see the invisible.”

To create a map of the local Universe, the authors used data on the motions of 56,000 galaxies from the Cosmic Flows-4 catalogue.

“Since the measurements of each galaxy’s velocity are error prone and fairly uncertain, there are various possible cosmographic maps that would fit the observational data,” they explained.

“Thus, we developed a new approach: a ‘probabilistic’ map of the Universe.”

“Such a map indicates how likely it is that a certain feature, such as a ‘basin of attraction,’ actually exists.”

“A basin of attraction is a region which, absent the cosmic expansion, would collapse to a single point.”

With this new method, the researchers obtained a reliable picture of the large-scale distribution of matter and revealed astonishing structures of our cosmic neighborhood.

“Laniakea, the supercluster to which many believed that our Galaxy belongs, is probably merely an appendage of the much larger Shapley basin. It may not even exist as a separate entity,” they said.

“Even more astonishing is the fact that the Sloan Great Wall — an immense wall composed of hundreds of thousands of galaxies — at around a thousand trillion trillion cubic light years is currently the largest known structure in this cosmic network of galaxies.”

“It is perhaps unsurprising that the further into the cosmos we look, we find that our home supercluster is more connected and more extensive than we thought,” said Dr. Noam Libeskind, co-author on the study.

“Discovering that there is a good chance that we are part of a much larger structure is exciting.”

Earth to Pass Through the Same Taurid Meteor Stream in 2032 That May Have Triggered a Mass Extinction 12,800 Years Ago

Earth will travel right in front of the same Taurid meteor stream in 2032 that caused a mass extinction and worldwide flood ~12,800 years ago, plunging Earth into a mini-Ice Age for 1,300 years. Graham Hancock was right all this time but we did not listen to him.

Our solar system is a dangerous place, and every month Earth inches closer to one of its riskier places, the “Taurid swarm” of meteors. Our planet is predicted to pass directly through the “Taurid swarm” in November 2032.

An ancient monument found in Turkey might be more than just a monument—it could be the world’s oldest solar calendar. Researchers from the University of Edinburgh studied symbols carved on the pillars of Göbekli Tepe, a large, ancient site in southern Turkey. They think these carvings were used to track days, seasons, and years, like a calendar. (Source)

The team noticed that each “V” shape carved on the pillars might represent one day. One pillar even had 365 “V”s, the same number as days in a year. They also found that a special “V” around the neck of a bird-like figure could represent the summer solstice—the longest day of the year. This might explain why the “V” symbol shows up on many other statues in the area, often around the necks of figures connected to time and creation.

Mini Ice Age

The ancient calendar focused on tracking day, night, and seasonal changes, which might have become more important after a major comet hit Earth around 10,850 B.C. This event likely caused a mini-ice age that wiped out many species. According to Martin Sweatman, a researcher from the University of Edinburgh, the people at Gobekli Tepe were careful observers of the sky, possibly because the comet strike had changed their world.

This disaster may have sparked the beginning of civilization by starting new religious beliefs and pushing people to develop agriculture to survive the colder climate. Their carvings might be some of the earliest attempts at writing. These carvings also tracked the cycles of the Moon and Sun, long before similar calendars were made. They may have even shown for the first time that comet strikes are more likely to happen when Earth crosses the path of comet fragments, something that modern scientists have confirmed.

To help support this theory, the team points to another pillar at the site appearing to picture the Taurid meteor stream lasting 27 days, which was quite possibly the source of the ancient comet strike. The researchers believe that the temple carvings show the ancient civilization was recording dates precisely, noting how the movement of constellations across the sky differed based on the time of the year. This would be 10,000 years before Hipparchus of ancient Greece documented the wobble in the Earth’s axis in 150 BC, making this newfound calendar well ahead of its time.

The Younger Dryas boundary (YDB) cosmic-impact hypothesis suggests that around 12,800 years ago, Earth was hit by pieces of a large comet, which broke apart as it entered the inner solar system. This event likely caused a chain reaction, leading to an “impact winter” (a period of intense cold) and a climate change episode called the Younger Dryas (YD). (Source)

The collision is also believed to have caused massive wildfires, the extinction of large animals like mammoths, and changes in human cultures and population decline. Evidence of this impact includes unusually high levels of platinum found at 26 sites across the Northern Hemisphere, including in ice cores from Greenland, which show platinum deposits over a 21-year period.

The start of the Younger Dryas also shows an increase in dust and chemicals linked to wildfires, like ammonium and other burning aerosols, found in ice cores from Greenland, Antarctica, and Russia. These signs point to one of the biggest wildfire events in over 120,000 years, with about 9% of Earth’s forests burned, covering 10 million square kilometers.

This large-scale burning and the cooling effect of the impact may have triggered the Younger Dryas climate change, according to the theory.

A 2021 study (Taurid complex smoking gun) found that 88 near-Earth asteroids, hidden in the debris that creates the Taurid Meteor Shower, likely came from the breakup of a single comet about 20,000 years ago. Astronomers at the University of Antioquia in Colombia studied the ‘Taurid complex’ to learn more about where these objects came from.

In the 1980s, scientists William Napier and Victor Clube noticed large asteroids in the Taurid stream. They suggested these asteroids had the same origin as Comet Encke, which orbits the Sun every three years. However, some asteroids are over a mile wide, meaning they couldn’t have come from Comet Encke itself. Scientists Ignacio Ferrín and Vincenzo Orofino reviewed old research and measured light reflected from the larger asteroids.

They found more evidence that both Comet Encke and the big asteroids came from the breakup of a huge ice comet, 62 miles wide, about 20,000 years ago. The team warned that these asteroids could be dangerous to Earth, and others from the ancient comet might have already hit our planet in the past. Every year, Earth passes through a stream of debris, causing shooting stars to appear in October in the southern hemisphere and November in the north.

Comet Encke, first seen in 1786, left a trail of debris as it got closer to the sun, like other comets. This trail, made up of rocks, dust, and debris, sometimes comes close to Earth, leading to lots of scientific study. Some studies focus on larger asteroids.

Experts think impacts from the Taurid stream may have contributed to the extinction of ancient cultures and global cooling during the Younger Dryas period. The 1908 Tunguska event, where a small asteroid exploded above Russia, destroying millions of trees, is believed to be connected to this debris stream.

In 2013, the Chelyabinsk meteor, which injured over 1,500 people in Russia, may have also come from the Taurid stream. In 2005, NASA astronomer Rob Suggs observed a flash from a meteor hitting the moon, which was part of the Taurid meteor shower.

A team of Colombian researchers, along with astronomers from Italy’s University of Salento, reviewed many studies on space impacts. They confirmed that a group of space objects contains up to 88 large pieces. Using a method called secular light curves, they noticed changes in the brightness of these objects and found that 67% showed signs of “comet-like” activity. This supported the idea that these objects came from a common origin.

Napier, another scientist, supported their findings. He said that these asteroids, which have orbits like Comet Encke, could either be affected by unknown forces or are pieces of a larger, older comet that lost its gases. This original comet may have been a “rubble pile” – a mix of rocks and other materials held together by ice. Over time, this pile could have broken apart, possibly due to forces from the Sun or another object, creating smaller fragments.

One asteroid, Oljato, is an example of a rubble pile. It’s still held together by ice, which gives it comet-like activity, but it’s much smaller than its parent. Bigger inactive objects like Morpheus are similar, but their ice is trapped inside. Smaller objects, like 2006 SO198, might be the original rocky pieces. The team explained that even if an object looks like a regular asteroid, it could still have a comet-like origin.

Taurid meteors, part of this group, are usually larger than normal meteors. They shine brightly and go deeper into the Earth’s atmosphere, sometimes creating fireballs. While this is mostly harmless, the discovery of larger asteroids in one “dangerous” part of the meteor stream could be a real threat.

Earth passes through this risky area every few years, leading to more shooting stars and possibly large objects hitting Earth instead of burning up in the atmosphere. Future encounters are expected in 2022, 2025, 2032, and 2039.

In 2021, David Asher, Armagh Observatory astronomer predicted that in 2032 and 2036 we are likely to pass through the centre of the Taurid complex, where there will be a ‘noticeable enhancement of fireballs.’ According to study [Taurid complex smoking gun] authors Ignacio Ferrín and Vincenzo Orofino, outgassing from comet-like objects within the complex could be hiding smaller, but still potentially dangerous, asteroids that might hit the Earth.

‘The Tunguska cosmic body was 60 to 90 meters in diameter,’ he told Discover Magazine, adding that we ‘now believe the complex may contain many more objects of that size. It is not the tame, simple and innocent complex we thought it was.’

Are we living in a simulation? Scientist claims we're simply characters in an advanced AI world - and says the proof is hidden in the BIBLE

• Passages from the Bible support the simulation hypothesis, physicist claims
• READ MORE: These everyday clues seem to suggest we're living in a simulation 

By Jonathan Chadwick For Mailonline 

If you feel like you're living in a convincing virtual reality akin to The Matrix, a scientist thinks you may well be right.

Melvin Vopson, an associate professor in physics at the University of Portsmouth, claims our entire universe may be an advanced computer simulation. 

And the proof that this so-called simulation hypothesis is correct may be hiding in plain sight in the Bible.

Professor Vopson told MailOnline: 'The bible itself tells us that we are in a simulation and it also tells us who is doing it.

'It is done by an AI – an artificial intelligence.' 

Professor Vopson points to the Gospel of John, one of the first four books of the New Testament, the second part of the Christian Bible

Professor Vopson points to the Gospel of John, one of the first four books of the New Testament, the second part of the Christian Bible. 

Gospel of John opens with the powerful statement: 'In the beginning was the Word, and the Word was with God, and the Word was God.'

The professor says this verse has 'deep theological significance in Christian doctrine', but it also carries 'intriguing implications' when considered in the context of the universe as a simulation. 

He argues that 'the Word' in this famous sentence refers to the underlying computer code that governs and controls the simulation. 

As anyone who has seen The Matrix will know, any computer simulation, big or small, consists of letters and numbers that write the rules for the entire creation. 

The academic further argues that 'the Word was God' could mean that God is part of the simulation, rather than separate from it. 

In other words, the entity that is controlling the whole thing – God – is written into the code too. 

Professor Vopson explains: 'The code running the simulation is not separate from the divine, but rather an integral part of it, perhaps an AI.'

In the blockbuster movie The Matrix, protagonist Neo, played by Keanu Reeves, discovers we're living in a simulated reality. By the end of the film, Neo is able to see the simulated world for what it is - computer code (pictured)

The simulated universe hypothesis proposes that what humans experience is actually an artificial reality, much like a computer simulation, in which they themselves are constructs. It formed the basis for the 1999 film The Matrix starring Keanu Reeves (pictured as his character wakes up in the real world)

Gospel of John goes on to say: 'All things were made by him, and without him was not anything made...'

Again, this statement supports the simulated universe theory, the professor suggests. 

'It implies a Creator who brought the simulated universe into existence through the Word (i.e. the code)' he says.

'It suggests that the act of creation, as described in the Bible, could be analogous to a divine act of programming and simulation.' 

Arguably, the theory offers an answer to a question that many Christians struggle with – how did God create the universe in six days?

If the theory's to be believed, he did so by creating a simulated reality encapsulated in a computer programme – something we know to be possible. 

The simulation theory 

Professor Vopson has outlined his hypothesis in his new book, 'Reality Reloaded: The Scientific Case for a Simulated Universe'. 

He says it is not even something he necessarily believes in, but a 'extraordinary observation that deserves attention'. 

'What is truly remarkable is that the interpretation given is fully aligned to the events of our times: the emergence of the AI, and also it is exactly what 'The Matrix' was projecting,' he told MailOnline. 

While the professor's thoughts may seem sacrilegious to some, he says it could have 'profound implications for Christian theology'. 

He believes there's an overlap where a belief in the simulated universe theory and the religious need for a almighty creator 'can coexist harmoniously'.  

'This perspective aligns with religious beliefs that hold human life to be meaningful and purposeful, even within the context of a larger design,' he says. 

'Instead of viewing the simulated universe hypothesis as antagonistic to religious beliefs, one can see it as offering a complementary perspective.'  

The professor has already said our lives contains several clues that suggest we're merely characters in an advanced virtual world. 

Melvin Vopson, an associate professor in physics at the University of Portsmouth, has outlined the clues that suggest we live in a simulated reality  

Professor Vopson thinks the prevalence of symmetry in the universe (pictured) suggests we are in a simulated reality because it's a way to save computational power 

For example, the fact there's limits to how fast light and sound can travel suggest they may be governed by the speed of a computer processor. 

The laws of physics that govern the universe are also akin to computer code, he says, while elementary particles that make up matter are like pixels. 

He also thinks the abundance of symmetry in the world – from flowers to butterflies and snowflakes – is a power-saving technique the machines use to render the digitally constructed world. 

The simulation theory is not unique to Professor Vopson; in fact, it's popular among a number of well-known figures including Tesla founder Elon Musk and American astrophysicist Neil Degrasse Tyson. 

At a 2016 conference, Musk said the odds that we're living in a 'base reality' – the real universe as opposed to a simulated one – are 'one in billions'. 

The term 'base reality' is part of an expansion on the theory that there are layers upon layers of fake realities that we need to somehow wake up from, akin to the film 'Inception'.

But as French philosopher René Descartes pointed out in 1637, 'Cogito, ergo sum', translated from the Latin as 'I think, therefore I am'. 

In other words, the ability to doubt the nature of our reality is essentially proof that we exist, in some shape or form.

China transformeerde maangrond in water: de eerste stap naar echte kolonisatie?

door Janine

NASA

Dat China plannen heeft om de maan en haar grondstoffen te gebruiken is zeker geen mysterie. Tegelijkertijd heeft het Aziatische land de afgelopen jaren verschillende sondes naar onze satelliet gestuurd, waaronder naar de verborgen kant. Meer recent is echter het nieuws dat een team van Chinese wetenschappers enkele monsters die door de Chang'e 5-missie naar de aarde zijn teruggebracht, heeft gebruikt om water te produceren. Zou dit de eerste stap kunnen zijn naar een toekomstige menselijke aanwezigheid op de maan? Laten we het samen uitzoeken!

Chang'e 5 en de maanmonsters teruggebracht naar de aarde

Zoals de naam al doet vermoeden, is de Chang'e 5-missie zeker niet de eerste die op de maan is gearriveerd. Het bijzondere aan deze missie is dat er voor het eerst in 44 jaar monsters van de maanbodem naar de aarde zijn teruggebracht. Ondanks de daaropvolgende Chang'e 6-missie, waarbij in plaats daarvan de verborgen kant van onze satelliet werd betrokken, zijn de resultaten van Chang'e 5 simpelweg buitengewoon. Zoals te lezen is in een recente studie gepubliceerd in het tijdschrift The Innovation, hebben Chinese wetenschappers ontdekt dat de mineralen waaruit de bodem van de maan bestaat rijk zijn aan waterstof en kunnen worden gebruikt om ter plekke water te produceren. Maar hoe?

De methode waarmee je water uit eenvoudige grond kunt halen, vereist het verwarmen van de mineralen waaruit het bestaat tot extreem hoge temperaturen, om een ​​chemische reactie van de elementen met waterstof te veroorzaken en daardoor tot de vorming van waterdamp te leiden.

Hoe je water van de Maan krijgt

Chen et al./The Innovation - 2024

Dankzij de innovatieve methode van Chinese wetenschappers kan uit elke ton maangrond ongeveer 50 liter water worden gewonnen. Het lijkt misschien niet veel, en het is ongetwijfeld een proces dat om verschillende redenen op aarde geen zin zou hebben. Op de maan verandert dit echter: 50 liter water kan voorzien in de dagelijkse behoeften van de leden van een hypothetische menselijke missie op een hypothetische maanbasis. De maanbasis vormt een concreet doel van de Chinese ruimteverkenning: het ter plekke kunnen produceren van water zou een enorm voordeel betekenen.

In feite wil China vòòr 2035 een permanent onderzoeksstation op de maan bouwen, terwijl China vòòr 2045 een ruimtestation in een baan rond de satelliet wil bouwen. Als Chang'e 5 na 44 jaar de eerste missie was die maanmonsters terugbracht, is de Chang'e 6-missie de eerste die monsters van de andere kant van de maan terugbracht. Kortom: China lijkt het serieus te nemen.

Naar een toekomstige maanbasis... en verder

Dat het mogelijk is om water rechtstreeks uit de maanbodem te halen is buitengewoon nieuws dat echter ook een aantal overwegingen met zich meebrengt. Allereerst moeten we begrijpen hoeveel energie er nodig is om de bodem te verwarmen en welke andere elementen betrokken zijn bij het proces van waterdampvorming. Ten tweede mogen we de geopolitieke implicaties niet vergeten van de belangstelling die China toont voor onze satelliet: de concurrentie om maanbronnen zal in de toekomst steeds levendiger worden. En mogelijk ook heviger.

Kortom, de resultaten van de Chinese Academie van Wetenschappen laten zien hoe het mogelijk is om steeds dichter bij het idee van een permanente aanwezigheid van de mens op de maan te komen. Aan de andere kant zijn er tientallen jaren verstreken sinds de laatste keer dat een astronaut een wandeling maakte op onze satelliet. De volgende zou wel eens een ruimtestation op de maan kunnen bewonen, op haar grond kunnen lopen... en haar water kunnen drinken.

Revolutie in de ruimtevaart: nieuw aandrijfsysteem maakt oneindige ruimtereizen mogelijk

Key takeaways

• Super Magdrive gebruikt direct beschikbare metalen in de ruimte als brandstof.
• Traditionele raketmotoren zijn afhankelijk van schaarse bronnen zoals xenon of krypton.
• Dit nieuwe systeem maakt gebruik van metalen zoals ijzer, aluminium en koper.

Onderzoekers van de Universiteit van Southampton ontwikkelen een baanbrekend aandrijvingssysteem dat direct beschikbare metalen uit de ruimte gebruikt als brandstof. Deze innovatieve technologie, bekend als Super Magdrive, zou ruimtetuigen in staat kunnen stellen om oneindige reizen door de kosmos te maken.

Traditionele raketmotoren zijn afhankelijk van schaarse grondstoffen zoals xenon of krypton, die overvloedig aanwezig zijn op aarde maar moeilijk te verkrijgen zijn in de diepe ruimte. Dit nieuwe systeem maakt daarentegen gebruik van metalen zoals ijzer, aluminium en koper, die in overvloed aanwezig zijn in ons zonnestelsel. Hoofdonderzoeker Dr. Minkwan Kim benadrukt in een gesprek met Sky News dat dit een revolutionaire benadering van ruimteverkenning is, waardoor ruimtetuigen zich ver in de kosmos kunnen wagen en gedurende langere perioden kunnen werken.

Kritische ontwikkelingen en samenwerkingsverbanden

Het team van Dr. Kim werkte samen met het Britse ruimtevaartbedrijf Magdrive aan de ontwikkeling van Super Magdrive. De Britse overheid heeft 1 miljoen pond beschikbaar gesteld om dit project te ondersteunen. Dr. Kim ziet deze technologie als een hoeksteen voor toekomstige missies in de diepe ruimte, die mogelijk tot ongekende ontdekkingen kunnen leiden.

Toekomstige implicaties en verwachtingen

Hij gelooft dat het een revolutie teweeg kan brengen in ons vermogen om nieuwe planeten te verkennen, naar buitenaards leven te zoeken en de grenzen van menselijke verkenning te verleggen door reizen mogelijk te maken die verder gaan dan eerder bedachte grenzen.

SpaceX launches mission to rescue astronauts stranded at ISS

A SpaceX spacecraft has lifted off to rescue two astronauts stranded at the International Space Station (ISS) due to technical issues.

NASA astronaut Nick Hague and Russian astronaut Aleksandr Gorbunov took off on Saturday from Cape Canaveral, Florida to bring back Suni Williams and Barry Wilmore.

The Dragon spacecraft, operated by SpaceX, the private company founded by billionaire Elon Musk, is set to arrive at the ISS on Sunday.

Originally, astronauts Zena Cardman and Stephanie Wilson were set to be part of NASA’s SpaceX Crew-9 mission.

However, they gave up their spots to accommodate Williams and Wilmore, astronauts stranded on the ISS due to technical issues with the Starliner spacecraft.

Williams and Wilmore were originally scheduled to return to Earth on June 13, after their Boeing Starliner capsule launched its first crewed flight from Florida’s Cape Canaveral Space Force Station on June 5. But the Starliner had been plagued with issues, even before the June 5 launch. A previous launch attempt was scrapped on June 1 just moments before launch because of a ground control computer performance issue.

During the 25-hour flight to the International Space Station, the spacecraft experienced several helium leaks and a malfunctioning thruster. Then, when the Starliner arrived on June 6 and attempted to dock at the ISS, four more of the 28 thrusters malfunctioned causing the ship’s arrival to be delayed.

Saturday’s launch of NASA’s mission had been delayed for several days due to the effects of Hurricane Helene. Weather concerns persisted until the last minute, with rain and storms posing risks to the mission.

“The crewmates will conduct more than 200 scientific investigations, including blood clotting studies, moisture effects on plants grown in space, and vision changes in astronauts during their mission,” read a NASA statement.

Williams and Wilmore are expected to return to Earth in February 2025, along with Hague and Gorbunov.

Canadian authorities have released an image of an unidentified object that was shot down over the country's Yukon Territory by a U.S. Air Force F-22 Raptor stealth fighter in February 2023.

Canadian authorities have released an image of an unidentified object that was shot  by a U.S. Air Force F-22 Raptor stealth fighter in February 2023. This is the first image of any of a trio of still-unidentified objects that were downed over the United States and Canada that month, details about which remain scant. The new disclosure continues to raise more questions about those incidents given that the picture appears to have been declassified within days of the shootdown, but was then withheld from release until now.

Canada’s CTV News first published the image of what is also known as Unidentified Aerial Phenomena (UAP) 23, seen at the top of this story and below, along with an accompanying string of partially redacted internal emails from members of the Canadian armed forces earlier today. UAP is the term U.S., Canadian, and other authorities currently use to refer to what have been commonly described as unidentified flying objects (UFOs) in the past. The outlet said it independently verified the records after recieving them from an unnamed source who had obtained them via an Access to Information request. Canada’s Access to Information Act is similar in many respects to the U.S. Freedom of Information Act (FOIA), but the former is only accessible to Canadian citizens.

UAP 23 was downed over the Yukon on February 11, 2023. This came two days after another unidentified object, also known as UAP 20, was shot down in U.S. airspace off the northern coast of Alaska. A shootdown of a third unidentified object as it passed over Lake Huron came on February 12. This all followed U.S. and Canadian authorities tracking a Chinese spy balloon passing through their airspace for days before deciding to destroy it as it soared out over the Atlantic Ocean off the coast of South Carolina on February 4.

The very low-resolution and grainy image we now have of UAP 23 shows a broadly doughnut-like shape with an open center, as well as an apparent notch or gap in its circumference on one side. It is possible that what is seen is light reflecting only from certain parts and that what is visible is not truly representative of its full shape.

The quality of the picture, which CTV News notes “appears to be a photocopy of an email printout,” makes it impossible to discern any definitive details. “The image appears to have been taken from an aircraft below it, although that has not been confirmed,” CTV News‘ report adds.

“The best description we have is: Visual – a cylindrical object. The top quarter is metallic, remainder white. 20 foot wire hanging below with a package of some sort suspended from it,” one of the associated emails, dated February 11, 2023, says. Looking at the released picture again with this description in hand it looks like it might show a balloon catching the sun with a payload underneath.

At the time, Canadian authorities described what had been shot down over the Yukon as a “small, cylindrical object.”

“It is unknown whether it [UAP 23] poses an armed threat or has intelligence collection capabilities,” according to a memo provided to Canadian Prime Minister Justin Trudeau on February 15, 2023, says. “The area in which the impact [after shootdown] occurred is a known (caribou) migration route, which opens the possibility of future accidental discovery by Indigenous hunters.”

CTV News published the heavily redacted document, which it also received from an unnamed source who obtained it first via an Access to Information request, in September 2023. The release of the memo had already raised new and still largely unanswered questions about what Canadian and U.S. authorities may or may not know about the trio of downed objects, as well as what other UAPs had been monitored in either country’s airspace before then, as you can read more about here.

No remains of any of the three still-unidentified objects brought down in February 2023 are known to have been recovered. The owners and/or operators of those objects, and whatever their purposes might have been, remain unknown, at least publicly. Past reports have suggested UAP 23, specifically, may have been a so-called “pico” balloon often launched by amateur radio enthusiasts.

U.S. officials subsequently said that the trio of objects appeared to be benign, which looks to have been a direct factor in withholding the image of UAP 23 from the public. The unredacted portions of the newly disclosed Emails, which you can find here, show a clear push between February 11 and February 15, 2023, including from then-Canadian Chief of the Defense Staff Gen. Wayne Eyre, to not only declassify the image, but also proactively release it, including on social media. However, by the end of February 15, the emails have taken a decidedly different tone.

“Should the image be released, it would be via the CAF [Canadian Armed Forces] social media accounts,” Taylor Paxton, then-acting Assistant Deputy Minister for Public Affairs with Canada’s Department of National Defense, writes in one Email. “Given the current public environment and statements related to the object being benign, releasing the image may create more questions/confusion, regardless of the text that will accompany the post.”

Major Doug Keirstead, Public Affairs Officer to Chief of the Defense Staff, subsequently sent another Email to his boss, Gen. Eyre, reiterating advice from acting Assistant Deputy Minister Taylor, as well as others, to hold off on releasing the image “pending U.S. engagement.”

The War Zone has reached out to the U.S. Office of the Secretary of Defense and the U.S.-Canadian North American Aerospace Defense Command (NORAD) for more information.

If the goal behind not releasing this image and any others from the Febraury 2023 shootdowns was to avoid confusion and speculation, it only appears to have had the opposite impact. The War Zone, along with others, has tried to obtain imagery from these incidents from the U.S. side on multiple occasions to no avail and we have called into question the puzzling optics of not doing so in the past.

Even before February 2023, many members of Congress in the United States with access to classified information had criticized and otherwise called into question the U.S. military’s attitude towards UAP issues, broadly. The Department of Defense did establish an All-domain Anomaly Resolution Office (AARO) in 2022 as a focal point for tracking and investigating all things UAP, but significant questions have been raised since about its resourcing and authorities. There have also been as yet unsubstantiated accusations of AARO and others within the U.S. government engaging in more active coverups.

“Data release and footage is prioritized based on the geopolitical environment at the time,” then-head of AARO Sean Kirkpatrick said in response to a question from The War Zone about why imagery from the February shootdowns had not been released at a press briefing in October 2023. “So engagements with Chinese fighters, Russian fighters have a much larger priority in getting it through the review process or declassification than UAPs or other similar engagements.”

“We are however, working through those processes, which all exist and we’ve got several of them actually already declassified and ready to update on our website [which] we’ll be doing on the next update to the website,” Kirkpatrick, who left AARO in December 2023, added at that time. “And we’re putting them out as quickly as we can get them through their proper steps.”

In a report released earlier this year, the Department of Defense’s own Office of the Inspector General (DODIG) went so far as to warn that a continued “lack of a comprehensive, coordinated approach to address” UAP issues “may pose a threat to military forces and national security.” The War Zone has repeatedly highlighted the significant evidence that a substantial number of UAP sightings are not only explainable, but are likely drones, high-altitude balloons, and other uncrewed aerial assets that hostile actors are using to gather intelligence on critical capabilities and installations in and round the United States.

A more recent Congressional effort to push for more UAP transparency through an amendment to the annual defense policy bill, or National Defense Authorization Act (NDAA), for the 2025 Fiscal Year looks to have collapsed, at least for now.

It will be interesting now to see whether or not the Canadian government’s decision to release the image of UAP 23, such as it is, and the accompanying emails, will lead to further disclosures about the February 2023 shootdowns by that country or the United States.

Image of Mysterious Object Shot Down Over Yukon Finally Released

In September 2024, a long-anticipated image of the mysterious object shot down over Yukon, Canada, in February 2023 was obtained by CTVNews.ca through a freedom of information request. The image, which has sparked significant public interest, shows a grainy, black-and-white representation of the object that was downed by a U.S. F-22 fighter jet after it crossed into Canadian airspace.

The object in question was one of three unidentified aerial objects shot down over North America within a short period, following the more widely reported downing of a Chinese surveillance balloon earlier that month. The object shot down over Yukon has been described in official documents as a “cylindrical” or “metallic” object with a tethered payload below it, although details have remained scarce, fueling speculation and public curiosity.

The Incident

The sequence of events leading to the downing of the object began when NORAD (North American Aerospace Defense Command) tracked the unidentified object as it entered North American airspace. After moving through Alaskan airspace, the object entered Canadian territory on February 11, 2023, prompting swift action from NORAD. Following discussions between Canadian Prime Minister Justin Trudeau, the Canadian Defence Minister, and U.S. authorities, the order to engage was issued.

At 15:41 Eastern Time, the object was shot down over the Yukon, and Canadian military personnel, in coordination with the RCMP (Royal Canadian Mounted Police), were deployed to recover the debris. However, due to challenging winter conditions in the remote and mountainous region, the recovery mission was ultimately called off just days later.

Description of the Object

Documents obtained by CTVNews.ca revealed some details about the object. In a memo dated February 11, 2023, a Canadian brigadier-general described the object as cylindrical, with a metallic upper portion and a long wire hanging beneath it, supporting a suspended package. Some officials speculated that it could be a balloon with a tethered payload, similar to other unidentified aerial objects encountered during that period.

Interestingly, these objects, including the one shot down over the Yukon, were described as being much smaller than the towering Chinese surveillance balloon that had drawn global attention just days before. Although there was much speculation about the nature of the Yukon object, U.S. President Joe Biden later stated that these unidentified objects were likely private or research balloons and posed no significant threat.

The Image and Public Reaction

The image obtained by CTVNews.ca, which was part of a heavily redacted set of documents, appears to be a low-resolution photocopy, making it difficult to discern specific details. Despite being cleared for public release shortly after the incident, the image was withheld due to concerns from public affairs officials, who believed its release could raise more questions than it answered. The image was discussed internally, with some military officials advocating for its release on social media. However, the public release was delayed, partly due to the lack of clarity in the image and its potential to fuel further speculation.

This image has now been made public, and while it adds a visual element to the mystery, it does little to clear up the questions surrounding the object’s origin or purpose. The shape of the object in the image has drawn comparisons to a balloon, with a horseshoe or crescent-like shape visible, but the lack of detail makes definitive conclusions difficult.

Secrecy and Speculation

The secrecy surrounding the object, its brief tracking, and the lack of debris recovery have all contributed to an air of mystery and speculation. While officials have publicly stated that the object posed no significant threat, the minimal information provided has led to various conspiracy theories and concerns about North American air defense vulnerabilities.

Experts have suggested that the U.S. and Canadian governments’ hesitation to release more information could be due to the sensitive nature of NORAD operations and a reluctance to disclose potential defense weaknesses. Iain Boyd, the director of the Center for National Security Initiatives at the University of Colorado, noted that withholding details may reflect concerns about how adversaries could exploit knowledge of such incidents.

Broader Context of Unidentified Aerial Phenomena

The Yukon object, referred to as “UAP 23” in some documents (with UAP standing for Unidentified Aerial Phenomena), was the 23rd such object tracked over North America in early 2023. The term UAP has largely replaced “UFO” (Unidentified Flying Object) in official circles, reflecting the shift toward a more scientific and data-driven approach to such sightings.

The February 2023 incidents of unidentified aerial objects prompted further scrutiny of UAPs by governments around the world. In Canada, the Sky Canada Project, led by the Office of the Chief Science Advisor, is expected to release its own report on UAPs later this year, as public interest in such phenomena continues to grow. In the U.S., the Pentagon and NASA have been more transparent about their investigations into UAPs, signaling a shift toward more open dialogue on the issue.

The release of the Yukon object’s image provides a glimpse into one of the more mysterious defense incidents of 2023. While the image adds to the body of evidence surrounding the event, the low quality and lack of detail leave many questions unanswered. As investigations into UAPs continue on both sides of the border, the public remains eager for further information about these objects and the implications they may have for air defense systems and international security.

Since Earth and the Moon have similar geological history, it made sense to look around on our planet for materials to simulate lunar dust. For LUNA, the agency partners created something called EAC-1. It’s based on volcanic powder spread out over the Eifel region in Germany some 45 million years ago. ESA has been working with this material for some years now, creating “moon bricks” that lunar colonists could use to build roads, launch pads, and habitats. Not only that, but lunar soil (like the EAC-1) contains a high percentage of oxygen. If astronauts can practice “cracking” that soil at LUNA, that would provide them with experience doing the same thing to tap in situ sources of oxygen they can use to survive.

More about LUNA

The LUNA main hall isn’t just a soil pit, however. It also has a specialized illumination simulator. That allows astronauts to recreate and practice their work under lunar day-and-night cycles. The Moon’s “day” is 14 Earth days long and a lunar night is the same length. Future astronauts and colonists will need to adapt their living and working conditions to those cycles.

Eventually, LUNA will also incorporate gravity off-loading systems. These are simulations of reduced gravity environments. Since the Moon’s gravity is one-sixth that of Earth’s, it’s important for astronauts to train in lower-gravity environments. Plans include a system similar to the Active Response Gravity Offload System (ARGOS) gravity system that NASA uses. It’s a device that suspends an astronaut trainee in a special trainer and uses sensors and other feedback that provide a simulated low-gravity environment.

In addition to astronaut training for low gravity and working with soil, LUNA will act as a testbed for operating robotic systems such as rovers and other tools. It will enable advanced science testing and activities, and teach astronauts how to build, manipulate, and operate energy systems. For example, researchers at the facility will test the regolith to understand the effects of moon dust on equipment space agencies plan to bring to the moon.

Preparing for Artemis and Beyond

All these activities should help future astronauts and mission planners develop solutions to challenges the Artemis and other explorers will face on the Moon. LUNA will also contain a unique habitat training area called FLEXHab. It is planned as a simulated habitat that will connect to the main facility.

Finally, ESA and DLR plan to repurpose a food production facility called EDEN-ISS. It’s actually a greenhouse that hosted a five-year-long food cultivation experiment. It will become part of the LUNA laboratory and is aimed at helping astronauts figure out how to grow and prepare food during their stay on the Moon.

Building accurate replicas of the lunar environment is a big training step toward permanent habitation on the Moon. The Artemis project will be one mission to take advantage of LUNA. Its mission timeline has slipped, but astronauts will still likely be headed toward the Moon within the decade. Test sites such as LUNA will play an important role in their training and eventual colonization activities.

This would seem to indicate that the Milky Way is rather typical. But then the team looked at those galaxies with a large companion, like the Large Magellanic Cloud we see in the southern hemisphere. For those galaxies the number of satellites is typically much larger than four. The Milky Way has an unusually low number of satellites. One reason for this may be that the Large Magellanic Cloud entered our sphere of influence rather recently on the cosmic timeline.

A second study based on the SAGA data looked at star formation in the satellite galaxies. It found that the closer a satellite is to the main galaxy the more likely it is to still be producing stars. This is similar to what we see among the Milky Way satellites. So it seems that while the Milky Way is a little unusual, it isn’t unique among galaxies of similar mass.

But it will always be our special spiral galaxy.
