Life After Death? Study Reveals Near-Death Experiences Are Not Hallucinations!
Life After Death? Study Reveals Near-Death Experiences Are Not Hallucinations!
Anew study exploring what people experience when they’re close to death has come to one important conclusion — “near-death experiences” are a real thing, even if we can’t explain them. Kinda like Madona's latest Instagram duckface selfie.
Countless people have claimed that their life “flashed before their eyes” or that they actually left their body and traveled somewhere else while close to death.
Critics have called these experiences hallucinations or illusions, but researchers from NYU Grossman School of Medicine say something else is actually happening.
A team of researchers from several medical disciplines — including neurosciences, critical care, psychiatry, psychology, social sciences, and humanities — have come up with a number of conclusions after reviewing unexplained –lucid – episodes which involve a heightened state of consciousness.
So really trying to find out what exactly a near-death experience is...
The main finding is that these events don’t have much in common with the experiences someone has if they’re hallucinating or using a psychedelic drug. Instead, people who have a near-death experience typically report five different events taking place:
A Separation from their body with a heightened, vast sense of consciousness and recognition that they’re dying
Or They “travel” to a different location
Some have said They have a meaningful and purposeful review of their life, involving a critical analysis of all their past actions — basically, their life flashes before their eyes
Some say they feel they are Going to a place that feels like “home”
And the feeling of Returning back to life
Researchers note that the near-death experience usually triggers a positive and long-term psychological transformation in the person. The team notes that people who had negative and distressing experiences while near-death did not experience these kinds of events.
The team found – It turns out that scientists can actually see physical changes taking place in the brain when someone is close to death.
Researchers found the presence of gamma activity and electrical spikes when people are technically dying. This is typically a sign of a heightened state of consciousness when scientists measure it using an electroencephalography (EEG).
The findings further back up the claims from people who say they “left their body” while dying.
Study authors note that advances in medicine over the last century have brought back countless people from death's door.
Lead author Sam Parnia said – QUOTE – “The advent of cardiopulmonary resuscitation (CPR) showed us that death is not an absolute state, rather, it’s a process that could potentially be reversed in some people even after it has started.”
Parina continued... “What has enabled the scientific study of death is that brain cells do not become irreversibly damaged within minutes of oxygen deprivation when the heart stops. Instead, they ‘die’ over hours of time. This is allowing scientists to objectively study the physiological and mental events that occur in relation to death.”
Study authors conclude that neither physiological nor cognitive processes completely end at the moment of death. While prior reports haven’t been able to prove what people are saying about their near-death experiences, the new report finds it’s also impossible to disprove what they’re saying.

UFO Bombshell: Pentagon forced to release secret study into UAP
Breaking UFO news from the Pentagon.. where officials have been forced to release an explosive report about UFOs under freedom of information laws. The new documents lift the lid on a secretive intelligence program, which was run by the United States Defence Force and employed more than 50 agents. The ‘UFO hunters’ researched health impacts on humans who reported paranormal experiences… and the findings are spooky.

“”A new spacefaring species… that’s the time they can meet and greet us without any need for permission from governments or presidents,…””

The blogger argued that this supposed UFO sighting was the result of aliens’ interest in data “about the newest rocket technology”.
Scott C. Waring, a prolific blogger with a penchant for seeking out information related to suspected signs of extraterrestrial activity, has announced the discovery of yet another UFO sighting that was apparently filmed in Florida in the vicinity of Playalinda Beach.
The video in question shows what Waring describes as “two tic-tac UFOs shooting behind the SpaceX Falcon rocket” prior to the launch on 9 March.
As the blogger explained, the original video was tweeted by his friend, while Waring himself produced a “close up video of it” and “slowed it down 8X” so that viewers could see the flying “object” which is “long, cylinder shaped, and metallic”.
“There is also another object above it that matches its speed,” he wrote in his blog. “Very strange, especially so close to a rocket launch site.”
The blogger also went on to speculate that this supposed UFO sighting was the result of aliens’ interest in data “about the newest rocket technology”, as such information can “help aliens predict the exact year that humans will begin migrating off Earth onto other planets and moons to live”.
“A new spacefaring species… that’s the time they can meet and greet us without any need for permission from governments or presidents,” he added.
No, no, this is NOT a broadcast from Moonbat Central! False fossils are objects that look like fossils but aren’t
As we sift more and more of the surface of Mars, we’d love to find fossils. But then we may run into a problem that dogs paleontologists on Earth. From the University of Edinburgh:
Rocks on Mars may contain numerous types of non-biological deposits that look similar to the kinds of fossils likely to be found if the planet ever supported life, a study says.
Telling these false fossils apart from what could be evidence of ancient life on the surface of Mars — which was temporarily habitable four billion years ago — is key to the success of current and future missions, researchers say.
A group of astrobiologists from the Universities of Edinburgh and Oxford have identified dozens of processes that “can produce structures that mimic those of microscopic, simple lifeforms that may once have existed on Mars.”
Dr Sean McMahon, Chancellor’s Fellow in Astrobiology at the University of Edinburgh’s School of Physic and Astronomy, said: “At some stage a Mars rover will almost certainly find something that looks a lot like a fossil, so being able to confidently distinguish these from structures and substances made by chemical reactions is vital. For every type of fossil out there, there is at least one non-biological process that creates very similar things, so there is a real need to improve our understanding of how these form.”
The paper goes into considerable detail; for example, for Mars:
The difficulty of correctly determining the biogenicity of life-like geological substances and structures has continued to plague palaeontology, and the new field of astrobiology, often despite laudable efforts to practice the ‘care, patience, and critical attitude’ recommended by Cloud. For example, McKay et al. (1996) reported multiple lines of evidence in the martian meteorite ALH84001 that were suggestive of past life on Mars, making news bulletins around the world. These included carbonate globules and magnetite crystals resembling bacteriogenic precipitates, polyaromatic hydrocarbon compounds and worm-like microstructures interpreted as morphological fossils. The origins of these features are still unclear today, but abiotic explanations have been offered for all of them, and the overall case for life in ALH84001 no longer seems compelling (Martel et al. 2012). This example warns us that it is not enough to have ‘multiple lines of evidence’ for biogenicity (an oft-repeated mantra) if each line of evidence is ambiguous.

and for Earth:
Other ongoing debates concern the oldest fossil and geochemical evidence of life on Earth. Schopf (1993) presented fossil ‘cyanobacteria’ from the 3.5-Gyr-old Apex Chert of Western Australia, which were later reinterpreted as abiotic carbon organized around spherulitic quartz growth and/or worm-like delaminated clay booklets (Brasier et al. 2002, 2005; Wacey et al. 2016a). Recent work highlights the possibility that organic matter in such cherts might be biogenic even if it has been abiotically redistributed (Duda et al. 2018), while Schopf et al. (2018) have claimed that morphology-specific carbon isotope values confirm the biogenicity of the Apex microstructures and reveal them to include methane-cycling archaea; this controversy continues (e.g. Alleon and Summons 2019). Nutman et al. (2016) described triangular features exposed on 3.7-Gyr-old metasedimentary rocks from the Isua supracrustal belt in Greenland and interpreted them as fossil stromatolites; these have been reinterpreted by some researchers as abiotic deformation features on the basis of 3D imaging and geochemical analysis (Allwood et al. 2018; Zawaski et al. 2020), although Nutman and co-workers stand by their original view (Nutman et al. 2021). Dodd et al. (2017) described hematite tubules in a c. 4-Gyr-old hydrothermal chert from the Nuvvuagittuq Greenstone Belt in Canada as the mineralized sheaths of ancient Fe-oxidizing bacteria; these have been queried as possible chemical gardens (McMahon 2019), but furtheranalyses are needed.

The trouble is, simple life forms leave only evidence, not messages so it can sometimes be hard to be sure.
On Earth, we can also be fooled about human tools or footprints. For example, from New Scientist we learn that sometimes, stones smashed by horses or monkeys can be mistaken for fragments of ancient tools.
Or it can go the other way: Just recently, it was discovered that footprints thought to be made by a bear were more probably made by humans 3.7 million years ago:
As bears walk, they take very wide steps, wobbling back and forth,” says senior author Jeremy DeSilva, an associate professor of anthropology at Dartmouth. “They are unable to walk with a gait similar to that of the Site A footprints, as their hip musculature and knee shape does not permit that kind of motion and balance.” Bear heels taper and their toes and feet are fan-like, while early human feet are squared off and have a prominent big toe, according to the researchers. Curiously, though, the Site A footprints record a hominin crossing one leg over the other as it walked — a gait called “cross-stepping.”
“Although humans don’t typically cross-step, this motion can occur when one is trying to reestablish their balance,” says McNutt. “The Site A footprints may have been the result of a hominin walking across an area that was an unlevel surface.”
Other researchers urge caution about the footprints — which reinforces the difficulty of certainty.
It won’t be surprising if we hear heated controversies about whether new finds on Mars are really fossils. But it’s a step in the right direction if astrobiologists have something concrete to argue about.
Mars may be dotted with "signs of life," but we've been fooled before.
Researchers urge caution in a new paper detailing the history of false "biosignatures."
Those include archaeological deposits that only look like bacterial cells and carbon-based molecules.
If we find fossils on Mars, there's a good chance that they're actually fakes, scientists warn in a new paper, published last week in the Journal of the Geological Society. And while it's easy to see how such a thing happens in the foreign atmosphere of space, the researchers say there are centuries of false fossil finds here on Earth, as well. It turns out it's easy to see something and draw the wrong conclusions—so will we get fooled again?
The paper, a review of existing research, looks at evidence of all known processes that could have created life on Mars. "It is often acknowledged that the search for life on Mars might produce false positive results, particularly via the detection of objects, patterns or substances that resemble the products of life in some way but are not biogenic," the authors note. "The success of major current and forthcoming rover missions now calls for significant efforts to mitigate this risk."
To reduce the risk of false positives, called "false biosignatures," we must look closely at the different processes that can give rise to deposits that appear to be fossils. These types of samples date back as long as people have been discovering geological artifacts on Earth. "In the nineteenth century, intricate layered and tubular structures found in rocks from the Canadian shield were interpreted as ancient forams, designated the 'dawn animal of Canada,'" the researchers explain. Experts later showed that these samples were inorganic, or non-living. This is a common theme. During the 20th century, paleontologists in other places around the world also mistook drag marks for "worm trails," for example, and natural pyrite crystallizations for organisms they named "medusae."

During the 20th century, paleontologists in other places around the world also mistook drag marks for "worm trails," for example, and natural pyrite crystallizations for organisms they named "medusae."
All these examples suggest that we should use caution with samples from Mars. "[T]he return of samples from Mars will not necessarily solve once and for all the problem of the existence of (ancient) life on that planet," the researchers explain. "Although we must hope for definitive results, candidate biosignatures are likely to be at least somewhat ambiguous." In fact, Mars itself has already hosted examples that are rather inconclusive, and Occam's razor—a philosophical principle that states that the simplest explanation is usually the best one—says these should still be taken as ambiguous rather than suggestive.
It's uncomfortable to live with ambiguity, especially when one possible explanation is so cool, like life on Mars. But the scientists urge caution and encourage other researchers to stay in the zone of ambiguity if that's what the evidence suggests. "To give an extreme example from Earth, the biogenicity of the filamentous mineral networks found in 'moss agates' has been unclear for more than 200 years," they explain.
So what are the potential red flags on Mars? Space programs already plan to do a more thorough exploration of Mars than we've seen from even very successful space probes and surface rovers, so there will almost definitely be new examples from those programs in the future. But to date, there are a couple of well-known examples: "These included carbonate globules and magnetite crystals resembling bacteriogenic precipitates, polyaromatic hydrocarbon compounds, and worm-like microstructures interpreted as morphological fossils."
All, the researchers say, are still ambiguous, with life as just one of many possible explanations. "Environments conducive to the origin and maintenance of life may also, by their very nature, be conducive to the formation of false biosignatures," the researchers say. Indeed, it makes sense that using caution in the beginning could lead to more believable and conclusive outcomes down the line.

Last year NASA announced that there were oceans on Mars and that it did look a lot like Earth in many ways. I guess this petrified fish is proof of that. Look closely and you will see the tail fin and the fin ridge that starts at the lower back fin and moves all the way to the fishes stomach. I colored the fish to make it easier on the eyes. The fish is also about half a meter long. About the size of a bass or small salmon. This also explains the three different boats we have found last year. This is 100% proof of ancient oceans on Mars.
I do feel NASA went overboard with their 2 billion dollar fishing equipment to catch this one, but its defiantly worth mounting on the wall. I hope they brought the tartar sauce. Lets see how NASA gets off the hook with this one, shall we?
“FUSION IS A SOURCE OF NEAR-LIMITLESS, CLEAN POWER,” NICK HAWKER TELLS INVERSE.
It sounds fantastic — an answer to the dire need to quickly transition to clean and sustainable energy. But is nuclear fusion our way out of the energy crisis?
Nuclear fusion is essentially the opposite of nuclear fission. That process, most commonly known as “nuclear power,” involves splitting atoms to release energy. Fusion instead involves smashing atoms into each other to create larger atoms — theoretically releasing vast amounts of energy. But unlike nuclear fission, this process comes without the same safety concerns over meltdowns or radioactive waste.
Hawker, CEO of First Light Fusion, a company currently developing a fusion energy system, sees the potential — and the money.
“More and more investment is flowing into the industry month-by-month, and this is helping us to help bring this potentially revolutionary technology closer to fruition,” he says.
He’s not wrong: The U.K. Atomic Energy Authority reported in 2021 that 18 companies worldwide had received a total of $1.9 billion in funding — $85 million of which came from official sources. Of all the companies dealing in nuclear fusion surveyed, 15 were founded in the last decade and 12 over the previous five years.
Yet the bounding enthusiasm is tempered by a history of false starts. No public or private organization has yet demonstrated a fusion reaction that generates more energy than went in to the reaction.
FUSION ENERGY: FOREVER 20 YEARS AWAY
Smashing atoms together sounds easy, but their forces repel the other. Fusion energy experiments typically involve smashing two hydrogen isotopes called deuterium and tritium. Mashing them together can release a lot of energy. But these two hydrogen atoms are both positively-charged, which means they repel each other.
Heat gets atoms moving. As the International Atomic Energy Agency explains, the goal is to heat them so much that they can move past their magnetic repulsion. They can collide and let a nuclear force overcome that repulsion.
Peter Norreys, professor of inertial fusion science at the University of Oxford, tells Inverse that recent breakthroughs show great promise. However, that does not mean that fusion energy is just around the corner.
“There are still big challenges remaining,” Norreys says. “I think there is an exciting future ahead for fusion energy, but the energy source will only be realized from mid-21st century onwards.”
In a February 1955 speech, Indian physicist Homi J. Bhabha says that controlled fusion energy would arrive within the next two decades: “When that happens, the energy problems of the world will truly have been solved forever.”
Even British prime minister Boris Johnson alluded to these delays during an October 2019 speech, when he promised £200 million ($262 million) in funding for the technology.
“They are on the verge of creating commercially viable miniature fusion reactors for sale around the world,” Johnson says — although it is unclear what he meant by “miniature” — before adding: “now I know they have been on the verge for some time…it is a pretty spacious kind of verge.”
It sounds like a dream for a world aiming to limit global average temperature rises to well below two degrees Celcius, as outlined in the Paris Agreement. In the last year, this permanently coming-soon form of zero-carbon electricity generation has made strides toward becoming a reality that can’t be written off. Here’s a quick timeline of some significant fusion breakthroughs:
In August 2021, the National Ignition Facility announced it was able to generate more than 70 percent of the energy inputted to reach 1.3 megajoules.
In January 2022, China’s Experimental Advanced Superconducting tokamak set a world record by reaching a temperature of over 70 million degrees Celsius for around 17 minutes — crucial for sustaining a fusion reaction.
In February, the Joint European Torus facility in the U.K. announced that it had produced an impressive 59 megajoules of energy over five seconds.
In March, British private company Tokamak Energy announced that its spherical ST-40 reactor reached a temperature threshold of 100 million degrees Celsius, which could enable commercially viable fusion.
Progress is good, but it is not the same as a proven technology that already works well. Wind and solar are proven technologies that exist today. Why invest in fusion?
The fusion energy process is similar to how the Sun burns material and unleashes energy. Elon Musk, whose company Tesla sells solar panels, describes the Sun in a 2020 Twitter post as a “free fusion reactor in the sky.” It may not be enough to solve our energy crisis, however.
Hawker’s company commissioned research into power usage over the coming decades and found that wind and solar could produce 19,900 Terawatt-hours per year. That’s an eight-fold increase from current rates but less than half of what’s needed to meet the 2050 net-zero target set by many countries.
The world will need to find power from clean sources of energy.Shutterstock
Other analyses have sketched out more ambitious rollouts of renewables, ones that don’t rely on fusion. The International Energy Agency’s “Net Zero by 2050” report, released in 2021, detailed a bold roadmap to meet climate targets. It describes how renewable energy could account for 90 percent of global electricity production by that date, with nuclear power accounting for less than 10 percent. Fusion does not receive a mention in the report — but advocates like Hawker say this is short-sighted.
One benefit of fusion is that it offers electricity generated on-demand, rather than only when the Sun is shining or the wind is blowing — a potential “complement” to renewable energy sources.
“To mitigate the impact of climate change, a large global market for baseload clean power will open up to complement renewables, and that is where fusion energy will play a key role,” he says.
The International Thermonuclear Experimental Reactor (ITER) project, a 35-country consortium that is currently developing the world’s largest fusion energy experiment, cites these major benefits of fusion:
6. Energy: The same amount of fuel as a traditional nuclear reactor generates four times as much energy in a fusion plant
5. Sustainability: Lithium in the ocean — an element necessary for fusion energy — could offer enough fuel for millions of years
4. Emissions: Zero carbon dioxide emissions
3. Waste: Fusion produces zero long-term radioactive waste
2. Risk: Fusion can’t be a precursor to nuclear weapons, and there is no meltdown risk
1. Cost: Fusion costs similar per kilowatt to a traditional nuclear reactor
We shouldn’t depend on fusion to save us — but it is another potential tool in our kit as we adapt to our climate reality.
Ultimately, the U.K.’s Atomic Energy Authority finds most fusion companies operating today in the world believe fusion will not power any grid anywhere in the world until the 2030s at the earliest. For a skeptical public that’s heard “two decades from now” for the past seven decades, it’s now down to the developers to prove that this time it’s different.
HOW WE GET THERE
Fusion energy involves colliding two, light, extremely hot atoms together to create a heavier atom. The colliding atoms heat beyond 100 million degrees Celsius to become plasma. The energy released when the atoms eventually fuse together is then transferred as heat through a water loop system to produce steam. The steam spins a turbine, and the turbine generates electricity.
There are two main methods that keep the fusion reaction going:
Magnetic confinement: Imagine a giant, hollow doughnut surrounded by magnets — that’s what’s being used to control all that hot plasma. This is the most popular method.
Inertial confinement: Facilities like the National Ignition Facility use a method to contain the plasma through its own inertia — in other words, a target gets hit and falls into itself, so the reaction is controlled by that motion instead of magnets.
The biggest hurdle to fusion energy actually working is that it is yet to generate more energy than goes into the reaction. Heating atoms up to temperatures similar to the Sun takes a lot of energy.
As we still haven’t gotten there yet, researchers continue to explore multiple avenues to see if we can make a breakthrough anywhere.
Inertial fusion is the less developed of the two. But a recent National Ignition Facility breakthrough — the first demonstration of burning inertial confinement fusion in a laboratory setting — shows it still has promise, Norreys says.
“[The results] are a really big deal, in my opinion,” Norreys says. “They show that the pursuit of an inertial fusion reactor is a realistic possibility for the future, one that is not built upon difficult and insurmountable physics.”
On the magnetic confinement side, the success of the Joint European Torus project bodes well for the upcoming ITER project. ITER, which will use the same fuel mix and wall materials as JET, aims to power the machine for the first time by December 2025.
"For the ITER Project, the JET results are a strong confidence builder that we are on the right track as we move forward toward demonstrating full fusion power," Bernard Bigot, director-general of ITER, said in a statement on the JET announcement.
“They [JET] are at the forefront of culture and are an outstanding example to the next generation on how to selflessly dedicate their energy and talent to the betterment of humankind,” Norreys says.
Exploding stars — or 'supernovae' — a mere 65 light years from Earth may have triggered the devastating mass extinction event around 359 million years ago.
The Late Devonian extinction saw vanish 50 per cent of all genera — groups of species — and 19 per cent of all families, the next largest grouping on the tree of life.
Among the groups to be worst impacted were the jaw-less fish, reef-building 'rugose' corals and the trilobites — iconic marine arthropods that look like woodlice.
This episode mass dying has previously been blamed on asteroid impacts, climate change, sea level changes and large-scale volcanic activity.
Researchers from the US, however, examined the boundary in the rock record between the Devonian and the next period, the Carboniferous.
Here lie hundreds of thousands of generations of plant spores that were sunburnt by ultraviolet light — suggesting a long-term weakening of the ozone layer.
This may have been caused by the impact of one or more nearby supernovae explosions on the solar system — and would have been catastrophic for life.
Exploding stars — or 'supernovae' — a mere 65 light years from Earth may have triggered the devastating mass extinction event around 359 million years ago. Pictured, an artists impression of a local supernova as seen from Earth orbit
'We propose that one or more supernova explosions, about 65 light-years away from Earth, could have been responsible for the protracted loss of ozone, said paper author and astronomer Brian Fields of the University of Illinois at Urbana-Champaign.
'Earth-based catastrophes such as large-scale volcanism and global warming can destroy the ozone layer too, but evidence for those is inconclusive for the time interval in question.'
Professor Fields and his colleagues also ruled out other space-based events that could have potentially caused ozone depletion — such as deadly gamma-ray bursts, meteorite impacts and solar eruptions.
'These events end quickly and are unlikely to cause the long-lasting ozone depletion that happened at the end of the Devonian period, said paper author and astronomer Jesse Miller, also of the University of Illinois.
In contrast, the researchers explained, a supernova has the potential to have a more lasting impact — especially given how they can deliver a 'one-two punch'.
Should a nearby star have gone nova, the Earth would shortly have been bathed in damaging ultra violet, X-ray and gamma ray radiation.
This would have be followed up by the debris blast from the explosion slamming into the solar system and subjecting our planet to irradiation from the cosmic rays accelerated by the supernova.
Together, the damage to the Earth's ozone layer would have likely lasted up to some 100,000 years, the researchers said.
Although this is not as long as the 300,000-year-spanning decline in biodiversity that led up to the end of the Devonian period, the supernova could have occurred in tandem with other catastrophes — or even multiple nova explosions.
'This is entirely possible. Massive stars usually occur in clusters with other massive stars, and other supernovae are likely to occur soon after the first explosion,' explained Mr Miller.
Should a nearby star have gone nova, the Earth would shortly have been bathed in damaging ultra violet, X-ray and gamma ray radiation. This would have be followed up by the debris blast from the explosion slamming into the solar system. Pictured, a simulation of a nearby supernova explosion battering and compressing the solar wind — with the Earth's orbit shown in blue and the Sun itself as the central red dot
Proof for the supernovae hypothesis, however, would need to come from finding evidence of the radioactive isotopes plutonium-244 and samarium-146 within the rocks and fossils deposited during the time of the mass extinction.
'Neither of these isotopes occurs naturally on Earth today and the only way they can get here is via cosmic explosions,' said paper author and astronomer Zhenghai Liu.
Or, as Professor Fields explains it, they are like green bananas.
'When you see green bananas [here] in Illinois, you know they are fresh, and you know they did not grow here.'
'Like bananas, Pu-244 and Sm-146 decay over time. So if we find these radioisotopes on Earth today, we know they are fresh and not from here — the green bananas of the isotope world — and thus the smoking guns of a nearby supernova.'
The search for these metaphorical bananas, however, will be a task for the future, the researchers explained.
The Late Devonian extinction saw vanish 50 per cent of all genera — groups of species — and 19 per cent of all families, the next largest grouping on the tree of life. Among the groups to be worst impacted were the jaw-less fish (pictured in this artist's impression) reef-building 'rugose' corals and the trilobites — iconic marine arthropods that look like woodlice
'The overarching message of our study is that life on Earth does not exist in isolation,' Professor Fields concluded.
'We are citizens of a larger cosmos, and the cosmos intervenes in our lives — often imperceptibly, but sometimes ferociously.'
Traditionally, scientists have referred to the 'Big Five' mass extinctions, including perhaps the most famous mass extinction triggered by a meteorite impact that brought about the end of the dinosaurs 66 million years ago.
But the other major mass extinctions were caused by phenomena originating entirely on Earth, and while they are less well known, we may learn something from exploring them that could shed light on our current environmental crises.
The Late Ordovician: This ancient crisis around 445m years ago saw two major waves of extinction, both caused by climate change associated with the advance and retreat of ice sheets in the southern hemisphere. This makes it the only major extinction to be linked to global cooling.
The Late Devonian: This period is now regarded as a number of 'pulses' of extinction spread over 20m years, beginning 380m years ago. This extinction has been linked to major climate change, possibly caused by an eruption of the volcanic Viluy Traps area in modern-day Siberia. A major eruption might have caused rapid fluctations in sea levels and reduced oxygen levels in the oceans.
The Middle Permian: Scientists have recently discovered another event 262m years ago that rivals the 'Big Five' in size. This event coincided with the Emeishan eruption in what's now China, and is known to have caused simultaneous extinctions in the tropics and higher latitudes.
The Late Permian: The Late Permian mass extinction around 252m years ago dwarfs all the other events, with about 96% of species becoming extinct. The extinction was triggered by a vast eruption of the Siberian Traps, a gigantic and prolonged volcanic event that covered much of modern day Siberia, which led to a cascade of environmental effects.
The Late Triassic: The Late Triassic event, 201m years ago, shares a number of similarities with the Late Permian event. It was caused by another large-scale eruption, this time of the Central Atlantic Magmatic Province, which heralded the splitting of the supercontinent Pangaea and the initial opening of what would later become the Atlantic Ocean.
Researchers from the University of Munich find evidence of a supernova near Earth.
A star exploded close to our planet about 2.5 million years ago.
The scientists deduced this by finding unusual concentrations of isotopes, created by a supernova.
If you wanted some more shattering news, we now know that a supernova exploded very close to Earth about 2.5 million years ago. That might sound like a long time ago, but in the life of our 4.5 billion-year-old planet, that’s just yesterday.
Supernovas are amazingly bright explosions of stars at the end of their lives. A recent study found a blast 4.5 million light-years away could release as much as 10 times the amount of energy that a sun can emit in its lifetime. It also spreads a tremendous amount of chemicals all throughout the cosmos. Just-released research looked at such a spread and found that concentrations of particular elements point to a supernova near Earth just 2.5 million years ago.
The scientists found an unusual amount of 53Mn, a radioisotope made by supernovas. Previous studies looked for such traces in concentrations of 60Fe, an isotope of iron.
The scientists, led by Dr. Gunther Korschinek from the Technical University of Munich, focused their study on ferromanganese crusts. These marine sediments, composed mainly of iron and manganese oxides, grow in time and jut out from the water. This makes them great record-keepers of chemicals in the water around them. While examining these ferromanganese crusts from locations in the Pacific Ocean, the team found not only the isotope 60Fe, but also 53Mn. The samples came from 1,589 meters (5,213 feet) down to 5,120 meters (3.18 miles) down.
What does the presence of 60Fe tell the researchers? It’s half-life of 2.6 million years indicates that it was created in a nearby supernova explosion in relatively recently times. Otherwise, 60Fe would have decayed into nickel.
One other explanation for the presence of the isotope is its possible creation in the death throes of asymptotic giant branch (AGB) stars. But the presence of 53Mn, which cannot be produced by such stars, clearly points to supernovae as the origin, think the scientists.
This Manganese crust started to form about 20 million years ago. Growing layer by layer, it resulted in minerals precipitated out of seawater.Elevated concentrations of 60 Fe and 56 Mn in layers from 2.5 million years ago hints at a nearby supernova explosion around that time.

“The increased concentrations of manganese-53 can be taken as the ‘smoking gun’ – the ultimate proof that this supernova really did take place,” shared Dr. Korschinek in a press release.
The researchers used accelerator mass spectrometry to locate the 53Mn atoms in the crust that looks like hardened chocolate cake.
“This is investigative ultra-trace analysis,” said Korschinek. “We are talking about merely a few atoms here.” He explained further that the technique is also very useful in figuring out the sizes of the original stars, adding “accelerator mass spectrometry is so sensitive that it even allows us to calculate from our measurements that the star that exploded must have had around 11 to 25 times the size of the sun.”
If there was a supernova in Earth’s relatively recent history, what effect did it have on the planet? The scientists think it likely caused cosmic ray showers and affected the climate. It might have also caused a partial extinction event – the Pliocene marine megafauna extinction
Our Sun’s days are numbered. In about 5 billion years the Sun will expand into a red giant, casting off its outer layers before settling down to become a white dwarf. It’s the inevitable fate of most sunlike stars, and the process is well understood. But as a recent study shows, there are still a few things we have to learn about dying Suns.
This recent study looks at a star known as V Hydrae or V Hya for short. It’s a red giant star about 1,300 light-years away with a mass roughly the same as the Sun. It’s what the Sun might look like in a few billion years. There are, however, a couple of things that make it different from our home star.
For one, it has a companion star. The companion is too faint for us to see, but based on the motion of V Hya, we know it is likely a red dwarf star that orbits V Hya once every 8.5 years. For another, V Hya seems to be dying in an unusual way.
In its current state, V Hya is categorized as a Mira variable star. It varies in brightness by about 1 – 2 magnitudes every 530 days, give or take. This is typical for dying red giant stars. As they fuse heavier elements in their core trying to survive, red giants often enter a period of oscillation, driven by the heating and cooling of the core. What’s more unusual is the fact that it is also a carbon star. This means that carbon fused in its core has been dredged up to the atmosphere of the star. So when astronomers look at V Hya’s spectrum, they see a strong presence of carbon. Basically, the star’s atmosphere is very “sooty.”
These two characteristics combined make V Hya an Asymptomatic Giant Branch star or AGB. About 90% of sunlike stars will enter an AGB period toward the end of their life. Astronomers have generally thought that the AGB epoch is a gradual process of stellar death, where the outer layers of the star are cast off over a period of about 100,000 years. After which, the remaining core collapses into a white dwarf. But V Hya shows this is either partly or sometimes incorrect.

If an AGB gradually cast off its outer layers, then we would expect to see an ever-expanding nebula known as a [planetary nebula](/post/cold-embers/) surrounding most white dwarfs. And we do see many planetary nebulae as the remnants of sunlike stars. But observations by the Atacama Large Millimeter/submillimeter Array (ALMA) show that V Hydrae isn’t creating such a nebula. Instead, it has been casting off thick rings rich in carbon. The star has ejected six rings over the course of about 2,100 years. The team also observed jets of gas ejected from the star perpendicular to the rings. This suggests that V Hya undergoes an unusually active period every few hundred years, which is very different from the common AGB model.
This period of active bursts is likely short lived compared to the full AGB epoch, so astronomers are fortunate to capture a dying star in this stage. It isn’t known whether most AGB stars experience such active periods, or whether V Hya is particularly unusual. To solve that mystery, it will take more observations of other dying red giant stars.
It’s Been Three Months in Deep Space, and Webb’s Mid-Infrared Instrument is Still Cooling Down
It’s Been Three Months in Deep Space, and Webb’s Mid-Infrared Instrument is Still Cooling Down
The James Webb Space Telescope continues to cool down out at its location at Lagrange Point 2, about 1.5 million kilometers from Earth. Since JWST is an infrared telescope, it needs to operate at extremely low temperatures, about 40 k (-223 degrees Celsius, -369.4 degrees Fahrenheit). But one instrument needs to be even colder.
To operate at peak efficiency, Webb’s Mid-Infrared Instrument (MIRI) must be cooled to a chilly 7 K (-266 C). And it will need a little help to reach those frigid temps.
Most of the telescope and its instruments rely on JWST’s massive sunshield as well as passive cooling, taking advantage of the frigid temperatures in deep space. The near-infrared instruments (NIRCam, NIRSpec, FGS-NIRISS) have now reached their target range from 34 to 39 K by cooling passively.
MIRI carries detectors that need to be at less than 7 kelvins to be able to detect longer wavelength photons of infrared light. This temperature is not possible on Webb by passive means alone, so Webb carries an innovative cryocooler, dedicated to the task of cooling MIRI’s detectors so that it can see farther into the infrared than the other instruments.
Previous infrared missions, such as the Spitzer Space Telescope, used a tank of cryogenic liquid helium that acted as a coolant by producing a freezing vapor that cooled the entire telescope assembly. But the vapor was vented to space, and once the supply helium was gone, the ability to cool the telescope was over. Spitzer launched in 2003 and the mission ended in 2020.
But MIRI’s cooler reuses its helium, just like the refrigerator in your kitchen continuously recycles its own coolant.
“Over the last couple weeks, the cryocooler has been circulating cold helium gas past the MIRI optical bench, which will help cool it to about 15 kelvins,” explained Konstantin Penanen and Bret Naylor, cryocooler specialists, NASA JPL, in a JWST blog post. “Soon, the cryocooler is about to experience the most challenging days of its mission. By operating cryogenic valves, the cryocooler will redirect the circulating helium gas and force it through a flow restriction. As the gas expands when exiting the restriction, it becomes colder, and can then bring the MIRI detectors to their cool operating temperature of below 7 kelvins.”

This type of recycling cooler also means the lifetime of MIRI instrument, as well as the entire JWST could be even longer than Spitzer’s 16 years. Webb engineers have mentioned a possible 20-year lifetime, or even longer.
Once MIRI reaches the final temperatures, engineers can begin the final phase of commissioning the telescope.
“Getting this instrument cold is one of the last major challenges faced by Webb before the MIRI team can truly relax,” wrote Alistair Glasse, Webb-MIRI Instrument Scientist, UK Astronomy Technology Centre and and Macarena Garcia Marin, MIRI Instrument and Calibration Scientist, ESA. They said the cryogenic cooler will “pull out almost all of the heat left in MIRI’s 100 kilograms (220 pounds) of metal and glass from that tropical launch day morning, three months ago. MIRI will be the last of Webb’s four instruments to open its eyes on the universe.”
Astronauts are Practicing Landing at the Moon's South Pole
Astronauts are Practicing Landing at the Moon's South Pole
The European Space Agency (ESA) is learning how to touch down safely at the South Pole of the Moon, without ever leaving Earth. Actual Moon landings seem to be on the horizon in the next decade via the Artemis program, and astronauts are going to have to learn to handle the unique challenges of landing in the Moon’s polar environment. With low angle sunlight and deep, permanently shadowed craters, the Moon’s South Pole poses difficulties no Apollo mission ever faced. To get hands-on experience with this environment without risking human life, ESA is putting astronauts through their paces on high-tech simulators.
Simulators have long been a part of space exploration. Movie fans probably remember Gary Sinise – playing astronaut Ken Mattingly in the classic 1995 film Apollo 13 – denying himself sleep and rest to run test after test in the simulator, searching for a way to bring the mission’s endangered crew home safe. In real life, NASA used a variety of simulators during the Apollo era to test different aspects of the program.
The most visceral Apollo testbed was the rocket-powered Lunar Lander Research Vehicle (LLRV), designed to simulate landing in a low-gravity environment. The LLRV gave Neil Armstrong and his colleagues valuable practice on Earth before testing the real thing on the Moon. but the LLRV came with its own risks. It crashed several times, forcing Armstrong and other pilots to make use of the built-in ejection seat and parachute to safety. Still, it was better to crash on Earth than on the Moon!
A Lunar Landing Research Vehicle (LLRV) being tested in 1964. This simulator recreated the low gravity conditions of landing on the Moon, and was used to train Apollo astronauts.
ESA’s new simulator, part of the ‘Human-In-the-Loop’ flight vehicle Engineering study, doesn’t leave the ground or rely on rockets – it’s built onto a large-scale robotic arm, which is able to move and shift at extreme angles to simulate the effects of the commands the astronaut gives the computer. Based at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), the Robotic Motion Simulator is a feat of engineering in its own right.
ESA astronaut Robert Vittori, who has been to space three times before, put the simulator through its paces. “The simulator is an incredible machine, probably one of the best I have experienced,” he said. “This experiment today is for me showing that Europe can play a key role in the future of exploration.”
ESA astronaut Robert Vittori stands in from of the DLR Robotic Motion Simulator.
Vittori tested various scenarios, including overriding the autopilot that was set to land in a field of boulders, and switching to manual control when the computer developed a fault.
The philosophy of ESA’s Human-In-the-Loop program is that hardware engineering and software design choices for spacecraft ought to be made in cooperation with the humans who will be flying the machines. The human-machine interfaces need to be user-friendly and intuitive, so that at critical moments, like landing on the Moon, there are no surprise design flaws or pilot confusion over the controls.
A similar philosophy enabled the success of the early days of spaceflight, when the Mercury astronauts worked closely with the engineering teams building the capsules and systems. Astronaut Wally Schirra, for example, specialized in life support systems and space suit development, while his colleague Scott Carpenter worked with the team building navigational equipment. In the present day, ESA is taking this philosophy to the next level. “We’re establishing a preliminary design and the preliminary requirements for human lunar landing, with astronauts in the loop to improve robustness and reliability of the flight system,” says project manager Luca Ferracina.
ESA has been heavily involved in the Artemis program since the beginning. It designed and built the service module of the Orion capsule, which will take astronauts to lunar orbit, working closely with NASA and other international partners. ESA astronauts will be on board at least three of the Artemis missions to the planned Lunar Gateway space station in the coming decade.
Guys, you gota check out the video I made below, I explain everything. A UFO was seen burning and falling slowly over Alaska at the Lazy mountain area. The object was depending slowly because one eyewitness said the photos were taken 45 seconds apart! Thats slow! Way too slow to be a meteor. If it was space junk, NASA would have alerted the public. Had it been a US hypersonic missile test, the US gov would admit to it, because they want to get in the news and frighten China and Russia with new weapons. However, this is a UFO and I reveal it to you in the video below. The UFO was caught in some of the photos, so...let me show you a close up of it to prove that it was a damaged UFO depending into an entrance on the mountain to enter an underground alien base.

News states:
When Mattias Ahlvin walked out of his house in Palmer to start his car Thursday morning, he saw something unusual in the sky. “I looked up and I saw this strange — I mean, I would just call it a smoke column. It was a dark, gray streak across the sky that was going straight vertical,” he said. Ahlvin pulled out his phone, zoomed in, and snapped a few photos of what he saw. His first thought was that it was a plane, but what surprised him was the direction the streak or plane seemed to be headed. “It looked like it was going straight down,” he said. Law enforcement and a meteorologist with the National Weather Service say that what Ahlvin saw was likely a condensation trail from an airplane that was illuminated by the rising sun. Ahlvin reached out to Alaska State Troopers to share the images of what he saw just in case it was an aircraft in distress, and his wife, Elisabeth, posted the photos to a local Facebook page asking if anyone knew what it was. Others posted similar photos and speculated whether they were looking at a rocket launch, a meteor, a plane crash, a volcano or perhaps a military operation.

Ancient Alien Face Found In Mars Crater, Google Map, UFO Sighting News
Location of discovery: Mars
Coordinates: 44°22'16.95"S 100° 3'31.39"W
I was checking out Google Mars...a free program to download and use, when I found this face. I have never reported on it before and it looks really big. Its hidden inside a crater and has a lot of similarities to the ancient China statues from thousands of years ago. If you know the name of the crater this is in, please tell us in comments. Google Mars ruler which is not extremely reliable, says that the diameter of the crater is 18.9km or 11.7 miles. The face itself is 8.9 miles (13km) by 5.9 miles (9.5 miles). That is one monumental undertaking to make, even making Mount Rushmore look like child's play. This face is highly detailed. No doubt is the face of a very notable historical figure in this species culture.

Alien Craft Seen Entering Side Vent Of Volcano In Mexico, April 2020, Video, UFO Sighting News.
Alien Craft Seen Entering Side Vent Of Volcano In Mexico, April 2020, Video, UFO Sighting News.
Date of sighting: April 1, 2022
Location of sighting:Volcano Popocateptl, Mexico
Omg! This UFO is trying to disguise itself as a meteor as it enters the side vent of the volcano. Yes, there is a well known side vent in the location that it hit. This UFO really lights up as it enters the side vent, making it appear as if it exploded, but it's actually traveling down the side vent into the underground alien base 6km below the base of the volcano. Look at the incredible speed it has as it enters the volcano. It's just extraordinary that it could move so fast in such a close proximity to hitting the tunnel walls it was traveling through. Only alien technology could make a craft travel so fast, so accurately and with such precision.

Dark Disk Over Tokyo, Japan, Creates Ring Of Light, Video, UFO Sighting News.
Date of sighting: April 1, 2022
Location of sighting: Tokyo, Japan
A UFO video emerged this week of an unknown object over Tokyo, Japan. The object pulses creating a ring of light around it, almost like lighting and then the UFO disappears.
Such UFOs have been frequently seen around Japan, but most often near Mt Fuji and near the Fukushima nuclear reactor. So aliens do have an extreme interest in Japan.
