Dit is ons nieuw hondje Kira, een kruising van een waterhond en een Podenko. Ze is sinds 7 februari 2024 bij ons en druk bezig ons hart te veroveren. Het is een lief, aanhankelijk hondje, dat zich op een week snel aan ons heeft aangepast. Ze is heel vinnig en nieuwsgierig, een heel ander hondje dan Noleke.

    Super-Earths and Sub-Neptunes Contain Much More Water than Previously Thought

    Water is an important component of exoplanets, with its distribution, that is, whether at the surface or deep inside, fundamentally influencing the planetary properties. According to new research, for Earth-size planets and planets more massive than 6 times the mass of Earth, the majority of water resides deep in the cores of planets.

    The majority of water can be stored deep within the exoplanet’s core and mantle, and not at the surface. Image credit: Sci.News.

    The majority of water can be stored deep within the exoplanet’s core and mantle, and not at the surface.

    “Most of the exoplanets known today are located close to their star,” said ETH Zurich’s Professor Caroline Dorn.

    “This means they primarily comprise hot worlds of oceans of molten magma that have not yet cooled to form a solid mantle of silicate bedrock like the Earth.”

    “Water dissolves very well in these magma oceans — unlike, for instance, carbon dioxide, which quickly outgasses and rises into the atmosphere.”

    “The iron core is located beneath the molten mantle of silicates. So how is the water distributed between the silicates and the iron?”

    “The iron core takes time to develop. A large share of the iron is initially contained in the hot magma soup in the form of droplets.”

    “The water sequestered in this soup combines with these iron droplets and sinks with them to the core. The iron droplets behave like a lift that is conveyed downwards by the water.”

    Until now this behavior had only been known to be the case for moderate pressures of the sort that also prevail in the Earth.

    It was not known what happens in the case of larger planets with higher pressure interior conditions.

    “This is one of the key results of our study,” Professor Dorn said.

    “The larger the planet and the greater its mass, the more the water tends to go with the iron droplets and become integrated in the core.”

    “Under certain circumstances, iron can absorb up to 70 times more water than silicates.”

    “However, owing to the enormous pressure at the core, the water no longer takes the form of water molecules but is present in hydrogen and oxygen.”

    This study was triggered by investigations of the Earth’s water content, which yielded a surprising result four years ago: the oceans on the Earth’s surface only contain a small fraction of our planet’s overall water.

    The content of more than 80 of the Earth’s oceans could be hidden in its interior.

    This is shown by simulations calculating how water behaves under conditions of the kind that prevailed when the Earth was young. Experiments and seismological measurements are accordingly compatible.

    The new findings concerning the distribution of water in planets have dramatic consequences for the interpretation of astronomical observation data.

    Using their telescopes in space and on the Earth, astronomers can under certain conditions measure the weight and size of an exoplanet.

    They use these calculations to draw up mass-radius diagrams that permit conclusions to be drawn about the planet’s composition.

    “If in doing so — as has been the case so far — the solubility and distribution of water are ignored, the volume of water can be dramatically underestimated by up to ten times,” Professor Dorn said.

    “Planets are much more water-abundant than previously assumed.”

    Water distribution is also important if we wish to understand how planets form and develop. The water that has sunk to the core remains trapped there forever.

    However, the water dissolved in the magma ocean of the mantle can degas and rise to the surface during mantle cooling.

    “So if we find water in a planet’s atmosphere, there is probably a great deal more in its interior,” Professor Dorn said.

    Water is one of the preconditions for life to develop. There has long been speculation about the potential habitability of water-rich super-Earths.

    Then calculations suggested that too much water could be hostile to life. The argument was that in these water worlds a layer of exotic high-pressure ice would prevent the exchange of vital substances at the interface between the ocean and the planet’s mantle.

    The current study reaches a different conclusion: planets with deep water layers are likely to be a rare occurrence as most of the water on super-Earths is not located on the surface, as has been assumed until now, but is trapped within the core.

    This leads the astronomers to assume that even planets with a relatively high water content could have the potential to develop Earth-like habitable conditions.

    “Their study thus casts a new light on the potential existence of water-abundant worlds that could support life,” the authors said.

    Cretaceous Amber Fossils Shed New Light on Evolutionary Origin of Tardigrades

    Tardigrades are a diverse group of microscopic invertebrates widely known for their extreme survival capabilities. Molecular clocks suggest that tardigrades diverged from other panarthropods (arthropods, tardigrades, velvet worms and lobopodians) before the Cambrian period, but their fossil record is extremely sparse. Now, paleontologists have described a new species of tardigrade and redescribed a previously known species, Beorn leggi, both from Canadian Cretaceous-aged amber.

    First discovered in 1773, tardigrades are a diverse group of microscopic invertebrates that are best known for their ability to survive extreme conditions.

    Also known as water bears or moss piglets, these creatures can live for up to 60 years, and grow to a maximum size of 0.5 mm, best seen under a microscope.

    They are able to survive for up to 30 years without food or water, for a few minutes at temperatures as low as minus 272 degrees Celsius or as high as 150 degrees Celsius, and minus 20 degrees Celsius for decades.

    Tardigrades withstand pressures from virtually 0 atm in space up to 1,200 atm at the bottom of the Marianas Trench, and are also resistant to radiation levels up to 5,000-6,200 Gy.

    They survive by entering a state of suspended animation called biostasis, using proteins that form gels inside of cells and slow down life processes.

    “Tardigrades are microscopic invertebrates characterized by a compact body plan with four pairs of typically claw-bearing lobopodous legs that are closely related to onychophorans and euarthropods as members of Panarthropoda,” said Harvard University Ph.D. candidate Marc Mapalo and colleagues.

    “Tardigrades are popularly known for the cryptobiotic ability of some species that allow them to survive extreme conditions, such as space vacuum, ionizing radiation, and low subzero temperatures, as well as their worldwide distribution in marine, freshwater, and terrestrial habitats.”

    “Despite their ubiquitous nature in the present-day biosphere, tardigrades have a notoriously scarce fossil record, which limits the study of their macroevolution including the origin of their body plan, and the timing of their terrestrialization and acquisition of cryptobiotic capabilities.”

    “Currently, there are only four known crown-group tardigrade fossils, all of which are preserved as amber inclusions, but only two of them have well-established taxonomic positions relative to extant tardigrades.”

    Aerobius dactylus. Image credit: Mapalo et al., doi: 10.1038/s42003-024-06643-2.

    Aerobius dactylus.

    Image credit: Mapalo et al., doi: 10.1038/s42003-024-06643-2.

    In their study, the authors looked at a piece of amber found in Canada in the 1960s that contains the known fossil tardigrade Beorn leggi and another presumed tardigrade that couldn’t be substantively described at the time.

    Using confocal laser microscopy, a method usually employed for studying cell biology, they were able to examine the tiny structures of the fossil tardigrades in stunning detail.

    The study provides not only a definitive classification of Beorn leggi in the tardigrade family tree, but the identification of a new species: Aerobius dactylus.

    “Both of them are found in the same piece of amber that dates to the Cretaceous period, which means that these water bears lived alongside dinosaurs,” said Dr. Javier Ortega-Hernández, also from Harvard University.

    “The images of Beorn leggi show seven well-preserved claws, with the claws that curve toward the body being smaller than those curving away from it, a pattern found in modern-day tardigrades.”

    “The second, previously unidentified specimen, had claws of similar length on each of its first three pairs of legs, but longer outer claws on its fourth set of legs.”

    Both species serve as critical calibration points for what’s called molecular clock analysis, which help scientists estimate the timing of key evolutionary events.

    For example, the latest findings suggest that modern tardigrades likely diverged during the Cambrian period over 500 million years ago.

    The study also sheds light on the origin of the remarkable ability of tardigrades to survive extreme conditions by entering a state of stasis.

    “The study estimates that this survival mechanism likely evolved during the mid to Late Paleozoic, which may have played a crucial role in helping tardigrades endure the end-Permian mass extinction, one of the most severe extinction events in Earth’s history,” Dr. Ortega-Hernández said.

    The results appear in the journal Communications Biology.

    Guys, I decided to use ai to focus this old sighting from 2016 and wow it blew my mind! The detail is amazing, but I have to admit, I have never seen anything like it. This is different, it's unique unlike anything ever. And it's flying slowly over top secret USAF land that is dangerous to enter.

    Hey all, I was asked by many followers of mine on Youtube to use my ai focusing program on something different. So here we go. This is a ship I discovered in the Florida Keys, USA back in 2023. Watch the video, see for yourself if ai is capable of focusing all photos or just human faces. The proof is in the pudding.

    Ancient mysteries of Russia's sacred Mountain Vottovaara

    The world is full of mysterious places, and Vottovaara Mountain in Russia's Republic of Karelia is one of them. This site has been revered for thousands of years by ancient Saami tribes and shamans, who considered it a sacred place surrounded with powerful energy.

    Vottovaara is home to numerous strange megalithic structures and ruins that many believe couldn't have formed naturally. Among these are around 1,600 sacred stones, known as "seids," arranged in a puzzling pattern. These stones, often unusually shaped, are precariously balanced on small rocks in ways that defy simple explanations. While scientists suggest that this was the result of natural processes during the Ice Age, the sheer number and precision of these balanced stones challenge the idea that they occurred by chance. 
    Another intriguing feature of Vottovaara is a structure referred to as "the well," which locals believe to be an ancient, man-made water reservoir. 
    As you climb Vottovaara, you'll notice an eerie transformation in the trees. None of the trees on the summit are older than a few decades, and while young pines and firs start growing normally, they soon begin to twist and deform in bizarre ways. This phenomenon is thought to be caused by some unknown energy affecting the trees. 
    Known as Death Mountain, Vottovaara also is believed to be connected to ancient spirits that are said to inhabit the area, adding to its aura of mystery.

    An eye-popping video of seven suns taken from a hospital in China has captured the attention and baffled viewers around the world.

    A woman was recording the sun’s descent over the horizon when something spectacular occurred - the image showed more than one sun in the sky.

    However, the minute-long video which seemed like a cosmic miracle was actually an optical illusion created by the glass window through which it was filmed.

    The phenomenon was caused by the light refracting through the window’s layered glass.

    The video was captured from the 11th floor of a hospital in Chengdu, China southwest of Sichuan on August 18, showing the sun duplicated with varying levels of intensity.

    The woman who reportedly captured the video, known as Wang, said viewers were transfixed by the surreal display, according to Jam Press, as many have offered theories about how the phenomenon occurred.

    ‘This happened because of a magnetic field glitch that made parallel universes visibly manifest,’ one person wrote on the Chinese social media platform Weibo.

    ‘The Cosmic Bureau has fixed the issue, and those responsible have been reprimanded,’ they added.

    Others argued on Reddit that the fragmented suns were a sign of ‘immense pollution’ in China and another person wrote: ‘The truth about global warming has finally been revealed.

    Meanwhile, one person simply joked: ‘Will the real Sun shady please rise up?’ in a nod to rapper Eminem’s famed hit ‘The Real Slim Shady.’

    However, one commenter did correctly address the question of how a video showed seven suns, writing: ‘This is caused by the reflection/refraction in glass in a multi-pane window. Light from the sun bounces between layers causing the distinct visual separation of the reflections.’

    Similar to how you would see a reflection in a mirror, the light refracted and reflected off the layered glass, with each layer creating another copy of the image.

    Except for the brightest sun in the center, which is the real one, the others are part of the optical illusion.

    Although there is a scientific explanation for the seven suns, some people still preferred to believe that the spectacle fell under the story of Hou Yi.

    In Chinese mythology, Hou Yi was portrayed as the god of archery who was sent from the Heavens to help humans.

    He is said to have stopped 10 suns from burning up the earth and according to the tale, shot them down with his magic bows and arrows.

    The tenth sun begged for its life and agreed to separate the day from the night as punishment for attempting to burn up the earth.

    EXCLUSIVE*Scientists demand the Shroud of Turin to be re-analyzed amid growing evidence it could be authentic

    Scientists are calling for a new analysis of the Shroud of Turin amid a seemingly growing body of evidence that challenges the idea it's a fake.

    There are also claims that bad data was used in a landmark 1988 UK study which found the shroud was a Medieval forgery and not the cloth Jesus was buried in.

    A new review by researchers from France and Italy has revisited those 30-year-old findings and claims to have discovered discrepancies in the data which were not made public and raise doubts about the definitiveness of the results.

    Tristan Casabianca, a French independent researcher, who made the find, told DailyMail.com that his findings do not confirm the shroud is older or the burial cloth used to lay Jesus to rest.

    But Casabianca - who was an atheist until he began investigating the shroud 20 years ago - said those factors could not be ruled out 'without a re-analysis.' 

    The research in question is a 1988 study that conducted radiocarbon dating on a piece of the shroud. Pictured are the sample containers that held strips of the cloth

    The 1988 study used a technique known as carbon dating to determine the age of the controversial Shroud of Turin

    The team determined with '95 percent confidence' the relic was manufactured sometime between 1260 and 1390 AD, long after the time of Christ's resurrection. 

    The conclusion was reached after analyses performed on a corner of the ancient fabric by three different labs - at the universities of Arizona, Zürich and Oxford.

    But after obtaining the raw data, Casabianca found the results varied by decades.

    One of Zürich's estimates in the Nature study said the cloth was up to 733 years old, but 595 years in the raw data.

    Oxford's shroud sample was between 730 and 795 years old, but the raw data featured estimates that were off by up to 55 years.

    Arizona's linen was between 591 and 701 years old, with the raw data showing a difference of up to 59 years.

    Even though that would still places the cloth in the Middle Ages, hundreds of years after Jesus, Casabianca said it raises doubts.

    He continued to explained that 'the lack of precision seriously affects the reliability of the 95 percent,' suggesting it was no more than 41 percent.

    Anything lower than 60 percent suggests that there is a lot of disagreement or inconsistency among the results, according to the 2019 study published in Archaeometry

    'We can say with confidence that the 1988 radiocarbon dating process led to a failure,' said Casabianca, who is an independent researcher in France.

    'It was supposed to close a book, and it has only opened a new chapter. This failure could have been avoided with a better protocol.'

    The raw data obtained by Casabianca showed it varied by decades than what was published in the Nature study. The red are changes made by the laboratories between their raw radiocarbon dates and the radiocarbon dates mentioned in the Nature article

    But Dr AJ Timothy Jull, who worked on the 1988 analysis, told DailyMail.com that even if the teams did re-run the analysis, 'The results would be the same, but the data would be less scattered.' 

    Dr Jull was part of the team at the University of Arizona.

    'Zürich was close to ours, but Oxford was a bit different,' Dr Jull said.

    'But that does not change the results. Others use this argument to say there is something wrong with the measurements, Casabianca tries to do this.'

    The Shroud of Turin is a 14-foot-long piece of linen featuring a faint image of the front and back of a man who Christians believe to be Jesus.

    The cloth was first presented to the public in the 1350s when it was exhibited in the small collegiate church in Lirey, a village in northern France.

    Christians believe those wounds were miraculously imprinted on the burial shroud after Jesus was resurrected from the dead, scorched into the fibers by a burst of energy when he came back to life.   

    Some believe it to be a Medieval fake, which Dr Jull and his team determined in the 1980s.

    The piece was cut from the bottom corner on the back of the shroud, which experts said was not mended in the Middle Ages

    The 1988 study saw scientists take a 10 mm by 70 mm piece of the shroud from the corner, which was cut into smaller pieces and distributed to the different labs.

    Co-author Emanuela Marinelli, an independent researcher in Italy, told DailyMail.com: 'The sample was not representative of the full cloth because it is different [from one corner from another].

    'The [1988] study found dating was more or less 150 years, so it is impossible to say the age of the entire 14-foot cloth.

    'But for us, it was the statistical analysis that is the reason to reject to carbon dating.'

    This technique estimates the age of organic materials based on the amount of radioactive isotope of carbon in them. 

    The results were collected and collated by London's British Museum, which held on to the raw data until Casabianca and his team issued a legal request under the Freedom of Information Act to obtain the raw information for the first time.

    'I received a reply from the British Museum with more than 200 pages of documents,' Casabianca said.

    'Our access to the documentation kept in the archives of the British Museum showed that the statistical analysis is supported by the documentation. 

    'In it, we find that the samples were contaminated (including cotton and rogue fibers). This suggests that the sampling was suboptimal, to say the least.'

    Dr Jull told DailyMail.com that he conducted another in 2010 to characterize the shroud samples, finding 'odd bits of cotton.'

    EXCLUSIVE New blood analysis of the Shroud of Turin 'supports Biblical story about Jesus' crucifixion'

    The agonizing crucifixion of Jesus from the Bible details how he endured severe beatings, punctures and nails driven into his hands and feet.

    Christians believe those wounds were miraculously imprinted on the burial shroud after Jesus was resurrected from the dead, scorched into the fibers by a burst of energy when he came back to life.

    Now, a new analysis of the Shroud of Turin - also known as the Holy Shroud - claims to have uncovered evidence that the crucifixion may be historically accurate.

    An engineer from the University of Padua in Italy used modern technology to reanalyze samples taken from the cloth in the 1970s, finding tiny blood particles showing signs of organ failure, trauma, disease and radiation. 

    Materials that were typical in ancient Jerusalem were also said to be discovered, suggesting that the shroud may have originated in the region and not in Europe where many skeptics think it was created as a medieval forgery.

    The new study analyzed blood samples taken from the shroud in 1978, which were collected using adhesive tape. This blood, according to the study, showed signs of disease, trauma and radiation

    Independent experts dismissed the findings, however, saying blood could have contaminated the cloth at any point in the past 700 years.

    The Shroud of Turin is a 14-foot-long piece of linen featuring a faint image of the front and back of a man who Christians believe to be Jesus.

    The cloth was first presented to the public in the 1350s, when it was exhibited in small collegiate church in Lirey, a village in northern France. Some believe it to be a Medieval fake.

    It was not until 1978 when the first physical samples were removed from the cloth, done using adhesive tape to carefully lift particles from the front fibers and a vacuum to collect dust from the back.

    But, back then, the results were inconclusive about whether or not blood had been present in the samples.

    Now, University of Padua professor Giulio Fanti has placed those samples under modern-day microscopes capable of highlighting details down to the size of individual particles.

    His study was published in Archives of Hematology Case Reports and Reviews, which peer-reviewed his research.

    The reanalyzed particles showed the presence of hemoglobin, which is a key component of blood, and also two different types of blood that Fanti labeled Type A and Type B. 

    Fanti says this suggests the cloth was used on someone with bloody injuries, rather than forged using ink, dye, paint or other techniques.

    Traces of creatine were also identified in the shroud sample, which is released into the blood stream when a person undergoes muscle breakdown or some type of trauma.    

    Your body produces creatine from amino acids in your liver, kidneys, and pancreas. It is also present in foods.

    The body releases the chemical into the bloodstream when cells in the brain, heart or skeletal muscles are damaged.

    It was not until 1978 when the first physical samples were allowed to be taken from the cloth, which was done using adhesive tape to carefully remove particles off the front fibers. Dr. Max Frei, a Swiss criminologist, can be seen taking samples from the shroud

    The expert found another type of blood that was shed while Jesus was still alive. It also contained signs of radiation, which Christians believe was released when Jesus rose from the dead

    'The high percentage of creatinine found in [the sticky tape samples], may be explained, especially during Jesus' last hour before dying on the cross, by a reduced blood flow to the kidneys also caused by hypovolemia and by severe dehydration,' the study reads.

    Fanti claimed that his findings align with John 19:28 that states 'Jesus said, I thirst.'

    The samples also featured signs the person whose blood allegedly stained the shroud had suffered from uremic syndrome which occurs when the kidneys are unable to eliminate waste products.

    While the condition typically happens from kidney disease, it can also be brought on by blunt trauma to the organ, which Fanti believes may have occurred when Jesus was whipped. 

    John 12:1 reads, 'Then Pilate took Jesus and had him flogged.'

    'I would refer to Type A blood as that which came out of the corpse and therefore postmortem blood; it consists of microcytes which indicate the respiratory suffering of Jesus on the cross,' Fanti, a Christian who has been studying the shroud for 25 years, told DailyMail.com.

    While the testing cannot prove whose blood litters the cloth, a new recent study claimed to find evidence that the shroud dates back 2,000 years

    This new finding came in stark contrast to a 1988 study which found the shroud to be a fake, after researchers determined it had been produced between 1260 and 1390 AD.

    The study analyzed samples taken from the 1970s. Researchers collected particles using adhesive tape. Pictured are the samples zoomed in 1,500 times

    In his study, Fanti found the blood particles he labled 'Type B' to mostly have a darker color than the 'Type A' blood and sharper edges.

    He claims this suggests Type B came from before Jesus had died, with the differences being due to clotting characteristics.

    'Type B consists of coagulated blood crusts probably formed when Jesus was on the cross or ascended Calvary,' said Fanti.

    Both types of blood also had traces of earth materials that Fanti said are typically found in Jerusalem, such as clay and limestone, suggesting that the shroud may have originated in the region.

    Mark 15:46 explains how Joseph, one of Jesus' disciples, removed Christ from the cross and 'bought a linen shroud, and taking him down, wrapped him in the linen shroud and laid him in a tomb that had been cut out of the rock.'

    Some believe that Jesus' body was not washed during that time, but quickly placed in the tomb, which means he was not cleaned of earthy materials before being wrapped.

    'When I went to Jerusalem to analyze the earthy material taken from the Holy Shroud, geologist Amir Sandler of the Geological Survey Of Jerusalem recognized among other things, like smectite and illite, which are typical of the Jerusalem soil as well as other material coming from the Sahara winds,' Fanti explained. 

    The blood detected by Fanti was also said to have evidence of possible radiation in different forms.

    The Type A blood contained Beta particles that are electrons of great kinetic energy emitted by some radioactive nuclei, such as Potassium-40 used in explosives and fireworks.

    Photon radiation particles were identified in the Type B samples - these are also known as Gamma rays, which are typically formed by a nuclear reaction.

    However, Dr Lawrence Kobilinsky, a forensic scientist who is a professor emeritus at John Jay College, told DailyMail.com that the 'blood' was likely a 'secondary thought.'

    'Earlier work... found a pigment [coloring agent] constituted the image,' he said.

    Indeed, American chemist Dr Walter McCrone, who analyzed the tape strips in 1978, found the image consisted of red ochre and a gelatin solution.

    'The simplest explanation is that this shroud was placed over a statue covered with pigment in certain areas, which transferred to the cloth, and gave it this three-dimensional configuration when you do the right kind of photography,' Dr Kobilinsky said.

    The shroud features a faint image of a man with long hair and a beard, which many believe is the face of Jesus

    study in 2018 also determined the shroud to be a fake after a new forensic investigation showed that its bloodstains were left by someone who had been standing – rather than crucified.

    Researchers concluded that the bloodstain patterns were also not consistent with a face-down corpse.

    Dr Matteo Borrini, a forensic scientist at Liverpool John Moores University, worked with chemist Luigi Garlaschelli, of the University of Pavia in Italy, looking at the orientation of the shroud's stains. 

    They sought to answer whether the crucifixion shown on the shroud was T-shaped, Y-shaped, or revealed another type of ancient Roman execution.

    What they found, however, was that the bloodstains were not consistent with any one pose in particular. This suggested that someone who had been standing was used to imprint the famous patterns at different angles for the hands, chest and back.

    Christians have claimed the imprints were created by energy released from Christ's body at the moment of resurrection.

    Scientists analyse the famous 'WOW!' signal first detected in 1977 - and finally reveal the truth about the mysterious flash

    • Scientists have new found evidence that the signal was not sent by aliens
    • The signal could have been caused by a natural microwave laser hitting Earth  

    In 1977, the Ohio State University's Big Ear radio telescope captured a signal from space so strange that scientists are still baffled by it almost 50 years later.

    For decades, scientists have struggled to find any natural process capable of producing the 72-second burst which prompted astronomer Jerry Ehman to write 'WOW!' on the telescope's readout.

    Now, new analysis of the so-called WOW! signal has revealed that it might have been caused by a hugely powerful laser slamming into Earth.

    Experts say this was not the first salvo of an alien invasion, but rather the entirely natural product of a rare alignment between a collapsed star and a cloud of cool hydrogen.

    Unfortunately for alien-hunters, scientists from the University of Puerto Rico at Arecibo say this new evidence shows that the WOW! signal is not evidence of life beyond Earth.

    For decades, scientists have struggled to find any natural process capable of producing the 72-second burst which prompted astronomer Jerry Ehman to write 'WOW!' on the telescope's readout

    What are the theories to explain the WOW! signal?

    There have been many theories over the years for what could have been the source for the short-lived, narrow band radio signal that became known as the Wow! signal.

    At the time, it was seen has having all the traits of having come from a distant planet, but the inability to pick it up again has frustrated astronomers.

    While some have taken it to be a radio message broadcast by an alien beacon into space, others have looked for other astronomical sources. 

    Theories have included collisions between asteroids and stars, flares from stars, merging white dwarfs and colliding neutron stars. 

    Now, experts suggest that it could have been caused by energy from a neutron star trigger a cloud of atomic hydrogen gas to release a laser burst. 

    When the WOW! signal hit Earth, many scientists put forward the idea that this could have been the first 'hello' from a distant alien civilisation.

    The signal was not only uniquely powerful but also arrived in an unusually narrow band of frequencies around 1420 MHz - similar to those produced by atomic hydrogen.

    Since hydrogen is so abundant in the universe, some suggested that advanced civilisations might be using its frequency as a calling card for signalling to other intelligent species.

    Other natural explanations for the signature have been proposed, such as passing comets releasing clouds of gas.

    In the absence of any good natural explanation, the idea that the WOW! signal was a 'technosignature' from another world became widespread.

    Now, Professor Abel Méndez and his colleagues believe they have identified a series of similar signals which could explain the WOW! signal's origin.

    The made the discovery by combing through the archives of the now-collapsed Arecibo Observatory's Radio Emissions from Red Dwarf Stars (REDS) project.

    Since this telescope had a similar experimental set-up to the Big Ear radio telescope, he hoped that it would be able to reveal if anything like the WOW! signal had ever been spotted.

    The researchers spotted several signals which appeared to be extremely similar to the WOW! signal, albeit considerably fainter.

    Researchers have used data from the now defunct Arecibo Observatory (pictured) to find signals that match the original WOW! signal. This evidence suggests it could be been the product of a giant space laser

    Four of those originated from the tiny red dwarf star, Teegarden's Star, which is just 12.5 light-years from Earth.

    Professor Méndez says: 'Our latest observations, made between February and May 2020, have revealed similar narrowband signals near the hydrogen line, though less intense than the original Wow! signal.'

    What makes Teegarden's star unique, however, is that it is surrounded by clouds of cool atomic hydrogen.

    When intense light from the red dwarf hits these clouds of hydrogen atoms, they are stimulated to produce a powerful burst of microwave energy in the 1420 MHz. 

    Researchers spotted similar bands of energy (pictured) being produced at fainter levels from a nearby red dwarf star called Teegarden's Star. Importantly this star is surrounded by clouds of atomic hydrogen

    The result is an entirely natural microwave laser, or maser, within the hydrogen range which looks extremely similar to that of the WOW! signal.

    The researchers argue that the WOW! signal was likely produced when an even more powerful burst of energy collided with a similar hydrogen cloud, producing an even bigger maser.

    A burst that powerful is rare, but could have been produced by a type of neutron star called a magnetar.

    These are formed when a star collapses and explodes into a supernova, leaving behind an ultra-dense, fast-spinning core with an extremely powerful magnetic field.

    If the burst from a neutron star hit a cloud of cool hydrogen gas it could trigger a colossal maser burst just like the WOW! signal.

    The signal may have been produced by a microwave laser triggered by the collision of energy from a magnetar (artists impression pictured) and a cloud of hydrogen gas. This means that the Wow! signal is not evidence for alien life

    The signal may have been produced by a microwave laser triggered by the collision of energy from a magnetar (artists impression pictured) and a cloud of hydrogen gas. This means that the Wow! signal is not evidence for alien life 

    Since it would be extremely rare for a magnetar to line up with a hydrogen cloud in just the right way, this also explains why we haven't heard the signal again.

    If true, this would mean there is no need to suppose that the WOW! signal is evidence of alien life.

    In their paper, published on arXiv, Professor Méndez and his colleagues write: 'Our hypothesis accounts for all observed characteristics of the Wow! signal introduces another source of false positives in technosignature searches, and suggests that this signal represented the first recorded astronomical maser flare in the hydrogen line.

    'We will continue with Arecibo Wow! exploring our extensive sets of observations from Arecibo REDS. Future studies will incorporate archival data from the Arecibo Observatory.'

    WHAT IS THE FERMI PARADOX?

    The Fermi Paradox questions why, given the estimated 200bn-400bn stars and at least 100bn planets in our galaxy, there have been no signs of alien life. 

    The contradiction is named after its creator, Italian physicist Enrico Fermi.

    He first posed the question back in 1950.

    Fermi believed it was too extraordinary that a single extraterrestrial signal or engineering project has yet to be detected in the universe — despite its immense vastness. 

    Fermi concluded there must a barrier that limits the rise of intelligent, self-aware, technologically advanced space-colonising civilisations.

    This barrier is sometimes referred to as the 'Great Filter'.

    Italian physicist Enrico Fermi devised the so-called Fermi Paradox in the 1950s. It explores why there is no sign of alien life, despite the 100 billions planets in our galaxy

    If the main obstacle preventing the colonisation of other planets is not in our past, then the barrier that will stop humanity's prospects of reaching other worlds must lie in our future, scientists have theorised.  

    Professor Brian Cox believes the advances in science and engineering required by a civilisation to start conquering the stars ultimately lead to its destruction.

     He said: 'One solution to the Fermi paradox is that it is not possible to run a world that has the power to destroy itself and that needs global collaborative solutions to prevent that.

    ‘It may be that the growth of science and engineering inevitably outstrips the development of political expertise, leading to disaster.'

    Other possible explanations for the Fermi Paradox include that no other intelligent species have arisen in the universe, intelligent alien species are out there — but lack the necessary technology to communicate with Earth.

    Some believe that the distances between intelligent civilsations are too great to allow any kind of two-way communication.

    If two worlds are separated by several thousand light-years, it's possible that one or both civilisation will be extinct before a dialogue can be established. 

    The so-called Zoo hypothesis claims intelligent alien life is out there, but deliberately avoids any contact with life on Earth to allow its natural evolution.

    I witnessed a UFO crash and aliens flee the ship - and I have a piece of the craft to prove it

    A man from Los Angeles claims that he witnessed aliens fleeing from a UFO after it crashed landed in the desert - and he has a piece of the spacecraft to prove it.

    Jose Padilla was just a nine-year-old boy growing up in San Antonio, New Mexico, when he and his friend discovered the 'avocado-shaped' UFO.

    To this day, he swears that what he witnessed was real. 

    Jose Padilla claims to have had a real alien encounter as a young boy living in San Antonio, New Mexico - he even has a piece of the UFO to prove it.

    Jose Padilla claims to have had a real alien encounter as a young boy living in San Antonio, New Mexico - he even has a piece of the UFO to prove it. 

    The encounter occurred while the two boys were horseback riding in the desert just 13 miles from the Trinity nuclear test site, Robert Oppenheimer and other members of the Manhattan Project detonated the world's first nuclear bomb in 1945.

    The encounter occurred that very same year, and at first, Padilla thought the sound of the crash was just another bomb test, he told CBS News Los Angeles. 

    'I told my friend, 'it must be another test from the bomb' and he said, 'no, it's not a bomb, look at the smoke coming out of the ground,'' Padilla said.

    Upon closer inspection, the smoke appeared to be coming from a crashed aircraft.

    Then, all of a sudden, three extraterrestrials emerged from the aircraft and began 'sashaying and running in circles,' he said. 

    But Padilla wasn't afraid of these creatures. 

    'They had crashed at my father's ranch, and they needed help,' he said. 

    Over the next ten days, the military cleaned up the wreckage while Padilla and his friend watched from a nearby ridge, despite being warned to stay away.

    'We were hiding behind cactuses,' he said.

    When the soldiers took a break from cleaning up the wreckage, Padilla and his friends entered the aircraft.

    The 'extraterrestrials' were gone, giving Padilla the perfect opportunity to extract a souvenir from inside. 

    He pulled a small 'dial' off the wall, brought it home and hid it in his garage. 

    Frontier Analysis, a chemical testing lab based in Ohio, analyzed the artifact in 2015. Their report revealed that it was made of aluminum mixed with silicon and copper, CBS Los Angeles reported.

    This mix of metals is commonly found in engine parts, and the report stated that the isotopic ratios were terrestrial.

    But an extraterrestrial source for the metals could not be ruled out, the report stated.

    'No one knows what it is,' Padilla said.

    The years passed, and Padilla moved from San Antonio to Rowland Heights, an unincorporated area of Los Angeles, California, and quietly raised a family.

    But he always held onto that strange artifact from his childhood.

    Padilla has held onto the strange metal artifact for all these years, claiming that it's proof of his alien encounter.

    In 2012, Padilla and the friend who was with him when he witnessed the UFO were interviewed by investigative journalist and UFO researcher Paola Harris. 

    At the time, Harris was investigating a claim by the son of World War II army pilot William Brophy.

    Brophy's son told Harris that one of his father's last missions was to fly over the area that Padilla claims the UFO crash landed in. During one such flight, he saw two young boys on horseback, Harris told CBS Los Angeles.

    She believes those two little boys were Padilla and his friend.

    What’s That? Look at What NASA’s Lunar Reconnaissance Orbiter Just Spotted on the Far Side of the Moon

    NASA’s Lunar Reconnaissance Orbiter (LRO) has captured new images of the far side of the Moon that have revealed the location of a Chinese spacecraft.

    The images obtained by the LRO on June 7 reveal the position of China’s Chang’e 6 sample return spacecraft, which was parked within the Apollo basin. This geologically rich region on the lunar surface features an abundance of basalt resulting from ancient lava flows on Earth’s natural satellite.

    Since landing on June 1, Chang’e 6 has been carrying out a robotic lunar exploration mission launched by China’s National Space Administration. The Chinese probe was initially launched in early May.

    Nearly a week after Chang’e 6 touched down in the Apollo basin, NASA’s LRO passed above its landing site, allowing it an opportunity to capture images that revealed the Chinese spacecraft’s location near the rim of a 50-meter crater.

    (Credit: NASA/GSFC/Arizona State University).

    With the new imagery in hand, LRO imaging experts were quickly able to determine the coordinates of Chang’e 6’s position to be roughly 42 degrees south latitude, 206 degrees east longitude, and placing the probe at an elevation of about minus 5,256 meters.

    The new imagery obtained by the LRO was released amid a flood of recent social media posts that falsely link earlier imagery obtained by NASA, some dating as far back as 2010, to the recent landing of Chang’e 6.

    Land of the Ancient Lunar Lava Flows

    Billions of years ago, the area where Chang’e 6 is carrying out its mission was the site of basaltic lava flows that made their way to the area, where they likely subsided once they met a geological fault believed to exist in the area.

    Chang’e 6’s landing site is roughly halfway between a pair of prominent dorsum or “wrinkle ridges,” features that are ubiquitous on lunar basalt plains and can sometimes reach several hundreds of kilometres in length. The basaltic flow in this region appears to overlap with an earlier one located to the west, which lacks the iron oxide and titanium dioxide that is evidenced by the adjacent younger basaltic formation.

    NASA’s Spy in Lunar Orbit

    Since June 18, 2009, the Lunar Reconnaissance Orbiter (LRO) has been observing the moon from its unique eccentric mapping orbit, providing crucial imagery for creating a 3D map of the lunar surface.

    Although the LRO was initially planned for a two-year mission, its operation was extended to gather data addressing various scientific questions, including the evolution of the moon’s crust and regolith.

    The recent photos the LRO obtained of China’s Chang’ e 6 spacecraft aren’t the first time NASA’s ever-watchful eye in lunar orbit has successfully spotted operations on the lunar surface undertaken by other countries. Last September, the LRO captured images of India’s Chandrayaan-3 spacecraft at its landing site. Also, in April of this year, the LRO managed to capture images of the Korea Pathfinder Lunar Orbiter (KPLO), an orbital spacecraft operated by the Korea Aerospace Research Institute (KARI).

    Mapping the Moon and Beyond

    Apart from photographing spacecraft sent to the Moon by other nations, the LRO has provided an unprecedented amount of information that has helped scientists expand our knowledge of Earth’s natural satellite. With a suite of high-resolution cameras and other powerful instruments, the LRO has succeeded at mapping the surface of the Moon with an impressive amount of detail, imagery which NASA has made available for viewing online.

    The LRO has played a significant role in several major discoveries, including the confirmation of water ice in craters on the Moon that remain in permanent shadow. Last December, the LRO also transmitted a laser beam from its laser altimeter instrument toward a tiny device on the Indian Space Research Organization’s (ISRO) Vikram lander, proving that the LRO could be used to locate retroreflectors on the surface of the Moon.

    Currently, Chang’e 6 is carrying out China’s second sample return mission. The samples collected by the lander were transferred to an ascender module and carried to an orbiter where it docked on June 6 for their transfer back to Earth. The Chang’e 6 lander and its associated rover have also conducted experiments while operating on the lunar surface.

    Additional information on China’s Chang’e 6 mission can be found here, and more about the ongoing operations of NASA’s Lunar Reconnaissaince Orbiter can be found on NASA’s official LRO mission webpage.

    The Universe is on the Move

    Our universe is defined by the way it moves, and one way to describe the history of science is through our increasing awareness of the restlessness of the cosmos.

    For millennia the brightest scientific minds in Europe and the Middle East believed that the Earth was perfectly still and that the heavens revolved around it, with a series of nested crystal spheres carrying each of the heavenly objects. Those early astronomers busied themselves with attempts to explain and predict the motion of those objects – the Sun, the Moon, each of the known planets, and the stars. Those predictions were excellent, and their systems able to explain the data well into the 16th century.

    But that cosmological system of motion, initially developed by Claudius Ptolemy in the 2nd century, wasn’t perfect. In fact, it was an ungainly mathematical mess, relying on small circular orbits nested within larger ones, with some centered on the Earth and some centered on other points. On his deathbed in 1543, the Polish astronomer Nicolas Copernicus published On the Revolutions of the Heavenly Spheres, a radical reformulation of the old Ptolemaic system that put the Sun at the center of the universe – still and motionless – with the Earth set in motion around it along with all the other planets.

    The reaction to the work of Copernicus was mixed and muted. On one hand, it was a bold and controversial reshaping of the universe. On the other, it was arguably just as messy and complicated as the Ptolemaic system it was trying to replace. And it introduced more than a few questions that had no easy answer. First and foremost, if the Earth was moving, how could we tell?

    We know we are moving on the surface of the Earth through a variety of ways. We can feel the wind against our face when we run, or watch as a distant goal draws nearer. So why don’t we feel a great rush of wind as the Earth orbits around the Sun? Or why aren’t we flung off into the void of space due to the incredible rotation of our planet?

    To all this, there were no ready answers. It would take another century and the development of Newton’s theory of gravity for the full picture to come together and make sense of the Earth in motion. Today we know that we don’t feel the motion of the Earth because we are in motion along with it, and since the vacuum of space is just that – a vacuum – there’s nothing for us to push against and betray that motion.

    Comparing Two Proposed NASA Missions to Jupiter’s Moon Io

    Thanks to NASA’s Juno mission to the Jupiter system, we’re getting our best looks ever at the gas giant’s volcanic moon Io. Even as Juno provides our best views of the moon, it also deepens our existing questions. Only a dedicated mission to Io can answer those questions, and there are two proposed missions.

    Io is well-known as the most geologically active world in the Solar System, and it’s not even close. It has over 400 active volcanoes. Io is the closest moon to Jupiter, and the planet’s powerful gravity is largely responsible for Io’s volcanoes. As the planet pulls on Io, the friction creates tidal heating in the moon’s interior. This creates magma and drives its volcanic eruptions. Sulphur compounds in the eruptions paint the moon’s surface in shades of red, yellow, white, black, and green.

    There’s never been a dedicated mission to Io, only missions that captured images as they passed by, including Galileo, Voyager 1, Cassini, New Horizons, and Juno, NASA’s current mission to Jupiter. But Io is intriguing and unique, and it can teach us a lot.

    Planetary scientists want to know more about the moon’s geological processes. Io is considered a high heat flux world, and scientists want to learn more about its tidal dissipation. Studying Io can also tell us more about primitive planetary bodies that were once more volcanic, which Earth likely was early in its history.

    Io can also tell us more about volcanogenic atmospheres, which can play a vital role in shaping a planet’s environment. This 2020 paper draws a link between Earth’s volcanic activity and the Great Oxygenation Event, a critical period when oxygen accumulated in Earth’s atmosphere. A better understanding of the link between volcanic activity and atmospheric evolution will help us better understand exoplanets and habitability.

    Scientists know that the Galilean moons exchange material with Jupiter’s atmosphere and magnetosphere. They also know that material ejected from Io’s volcanoes can reach the surfaces of the other moons. Some of it can be turned into plasma by Jupiter’s powerful magnetosphere, forming Io’s plasma torus. They’re curious about this mass exchange in the Jupiter system and how it’s shaped the moons.

    These are the reasons for a dedicated mission to Io.

    In 2010, scientists at the University of Arizona and Johns Hopkins University’s Applied Physics Laboratory first proposed the Io Volcano Observer (IVO) as part of NASA’s Discovery Program. IVO was proposed as a low-cost mission to explore Jupiter’s volcanic Moon. It was proposed again in 2015 and in 2019. In 2020, IVO was selected with two other missions for further study but ultimately lost out to the DAVINCI+ and VERITAS missions to Venus.

    Now, there’s another proposal for the Io Volcano Observer, but this time, it’s under NASA’s New Frontiers Program. The new proposal shows that the desire for an Io-focused mission won’t go away. Instead, it’s gaining steam.

    In a new paper still subject to peer review, a group of mostly American scientists present their case for the New Frontiers IVO. It’s titled “Comparing NASA Discovery and New Frontiers Class Mission Concepts for the Io Volcano Observer (IVO).” The first author is Christopher Hamilton from the Lunar and Planetary Laboratory, University of Arizona.

    The IVO NF would address our scientific questions by reaching three goals, according to the authors:

    • Determine how and where tidal heat is generated inside Io;
    • Understand how tidal heat is transported to the surface of Io;
    • Understand how Io is evolving.

    The original IVO proposal had the spacecraft encounter Io ten times in four years after reaching the moon in 2033. It would’ve carried five instruments, with a sixth under consideration. The IVO would’ve crossed Io from pole to pole, passing over the equator at an altitude of between 200 and 500 kilometres (124 and 310 miles.)

    The closest approaches were carefully designed to give the spacecraft the best observations of the moon’s magnetic field, gravity field, and libration amplitude. The approaches also would’ve allowed for both sunlit and dark views of volcanoes, allowing the spacecraft to study the composition of lava. The polar perspective would’ve provided new views of heat emanating from the moon that were unavailable to Galileo and unobservable from Earth.

    The new IVO NF proposal maintains the polar orbit of the original IVO but improves it in several ways. Universe Today talked with lead author Christopher Hamilton about the new proposal. His remarks have been lightly edited for clarity.

    The first change in the new proposal concerns the number of flybys, which would increase from 10 to 20.

    Both IVO and IVO-NF are great missions, but doubling the number of flybys more than doubles the scienctific return from an Io mission!

    Christopher Hamilton, Lunar and Planetary Laboratory, University of Arizona.

    “10 flybys for the original Discovery-level IVO mission would fill important gaps in image coverage that remain unfilled after the Voyager and Galileo era,” Hamilton said. So why double it?

    “The new tour not only doubles the image coverage of Io’s surface with high-resolution imaging but also enables more flybys of active volcanoes, like Loki, Loki Patera, and Pillian Patera,” Hamilton said. “These are highly dynamic volcanic systems that include active lava lakes and explosive eruptions—one pass over the volcanic systems is simply not enough to constrain their time-variability and eruption dynamics.”

    Like Earth’s Moon, Io is tidally locked to Jupiter, with one side more readily available for study than the Jupiter-facing side. But Jupiter’s effect on Io is much stronger than Earth’s effect on the Moon. “However, tidal interactions between Jupiter and Io are much stronger, exciting tides in solid rock with an amplitude of about 100 m (328 feet), which is taller than the Statue of Liberty!” Hamilton said. These tidal interactions drive Io’s powerful volcanism. “However, studies of the past decade have suggested that this heat has also melted a layer within Io to form a subsurface ‘”‘magma ocean,'” Hamilton said.

    The original IVO’s ten orbits, with its magnetometer instrument, would have confirmed or excluded this hypothesis. The new proposal will carry an improved version of this instrument, and with more orbits, it could answer questions about Io’s magma ocean.

    “IVO-NF would also carry a fluxgate magnetometer and with the repeat passes, carefully timed to measure Io’s induced magnetic field at different times in its orbit, would greatly reduce the uncertainty in estimating a potential magma oceans depth,” Hamilton said. The current uncertainty is ±10 km, but IVO NF would reduce it to ±3 km. This “would revolutionize our understanding of Io’s interior and the links between tidal heating and volcanism,” Hamilton told Universe Today.

    “Both IVO and IVO-NF are great missions, but doubling the number of flybys more than doubles the scienctific return from an Io mission!” Hamilton said.

    IVO-NF would also approach Io much closer than the original IVO. The original mission called for an altitude of 200 and 500 kilometres (124 and 310 miles) above Io’s surface. IVO-NF would begin its mission with high-altitude fly-bys, but as the mission progressed and objectives were reached, it would come much closer.

    “With 20 flybys, IVO-NF can be more daring, flying closer to Io’s surface and even flying through its volcanic plumes to determine the chemistry of its erupted products in unprecedented detail,” Hamilton told Universe Today.

    Initial flybys would be at about 200 km, “but as the mission progresses and Baseline objectives are achieved, we will be able to lower the altitude of later flybys over active volcanoes like Pele Patera,” Hamilton said.

    “Nonetheless, we would image and analyze these volcanoes first, making use of repeat coverage to further constrain the safety of the close approach, and take precautions like reorienting the spacecraft’s solar panels so that they fly through the plume side-on rather than exposing the full cross-sectional area,” Hamilton told Universe Today. “Plume flythroughs for Io would also open the door to other sampling opportunities for plumes on Saturn’s active moon, Enceladus.”

    “This may seem dangerous, but even at altitudes of 50 km, there would be very few particles,” Hamilton said. But before the spacecraft comes that close, it’ll use its Surface Dust Analyzer to understand the hazard. This instrument was added to the IVO-NF as a top priority. It will measure surface dust composition and the composition of nanograins in the volcanic plumes. Overall, it will give scientists a better understanding of Io’s dust environment and inform them if it’s safe to approach within 50 km.

    According to Hamilton, we’re experiencing a renaissance in exploring the Jovian system.

    “This is an important time in Planetary Exploration, and exploration of the Jupiter System is undergoing a renaissance, with Juno, Europa Clipper, and JUICE examining Jupiter, Europa, and Ganymede at the same time,” Hamilton told Universe Today. Io is a critical part of Jupiter’s moon system. It’s at the heart of the orbital resonance configuration between Io, Europa, and Ganymede, and the resonance drives geological activity on all three moons, including volcanism, tectonic activity, and the formation of surface features.

    “Juno has filled some important gaps left after the end of the Galileo mission (1995–2003), but IVO and IVO-NF would be the first to have an instrument suite that is optimized specifically for Io,” said Hamilton.

    To the intellectually curious, everything in nature is worthy of study and deeper understanding. An extraordinary world like Io is certainly no exception, with everything it has to tell us about itself, its sibling moons, and even about the early Earth and Moon.

    “Our paper makes the case that Io is a priority target for exploration that should be considered in the next New Frontier Announcement of Opportunity,” Hamilton told Universe Today. He acknowledges that the original IVO mission at the Discovery level is possible, but the IVO New Frontiers mission would accomplish a lot more and would more thoroughly address our outstanding questions about Io.

    “A larger mission to Io via New Frontiers would more than double the scientific return of the mission and would offer the best approach to understanding not just Io, but the Jupiter System as a whole, and the origins of high-heat flux worlds like the early Earth, early Moon, and other terrestrial planets in the Solar System and beyond,” Hamilton concluded.

    A former top Pentagon spy claims that the US has recovered 'aliens.'

    Former US counterintelligence official and onetime Pentagon UFO investigator Luis 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. His new explosive allegations come amid the ex-spy's press tour for his new memoir. They'll be broadcast in NewsNation's Special Report: Confessions of a UFO Hunter at 9PM ET on Friday August 23. 

    'We're not alone,' former Pentagon official Luis Elizondo (pictured) told Australian investigative journalist Ross Coulthart in an advanced clip of TC channel NewsNation's upcoming special. 'It is a simple fact,' he added. 'The US government has been aware of that fact for decades'

    'We're not alone,' former Pentagon official Luis Elizondo (pictured) told Australian investigative journalist Ross Coulthart in an advanced clip of TC channel NewsNation's upcoming special. 'It is a simple fact,' he added. 'The US government has been aware of that fact for decades' 

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

    The 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 cable network NewsNation in the new interview, 'vehicles of unknown origin that are neither from our country or any other foreign country that we're aware of.'

    'We're not alone,' the former Pentagon official told Australian investigative journalist Ross Coulthart in an advanced clip of the channel's upcoming special report.

    'We are not alone in this universe and it is a simple fact,' Elizondo continued. 'The US government has been aware of that fact for decades.. 

    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.

    The videos depict, as Elizondo told CNN, 'things that don't have any obvious flight sufaces, 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.' 

    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 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.

    'You take a nuclear carrier strike group, a nuclear powered aircraft carrier, you have a nuclear powered submarine and other nuclear equities in the area, and you put it on the water,' he told DailyMail.com.

    The idea was to gather warships in the ocean, focusing their radar, sonar, and cameras where they believed the UFOs would appear.

    'There was an official plan that had support. It got briefed all the way to the Joint Staff,' Elizondo said. 'We had a lot of interest from the intelligence community. A lot of agencies were part of this. They were ready to put their effort and assets into it. And at the last minute it got denied.'

    'That, for me, was one of the last straws,' he told DailyMail.com this past Saturday.

    600,000 Years Ago, A Transfer of Ancient Knowledge Kicked Off a Sudden and Rapid Advance in Technology

    Early humans appear to have experienced a sudden and rapid advance in technology around 600,000 years ago, according to new findings by a team of anthropologists exploring the use of ancient stone tools.

    The researchers behind the findings say this likely represents a key inflection point in ancient human development, where the transfer of ancient knowledge from generation to generation, known as cumulative culture, resulted in increasing advances in society that propelled humanity’s biological, cultural and technological development.

    “Our species, Homo sapiens, has been successful at adapting to ecological conditions — from tropical forests to arctic tundra — that require different kinds of problems to be solved,” said associate professor Charles Perreault, an anthropologist from Arizona State University’s School of Human Evolution and Social Change. and a research scientist with the Institute of Human Origins.“Cumulative culture is key because it allows human populations to build on and recombine the solutions of prior generations and to develop new complex solutions to problems very quickly.”

    Toolmaking Suddenly Underwent a Rapid Advance in Technology

    In their published study, “3.3 million years of stone tool complexity suggests that cumulative culture began during the Middle Pleistocene,” which appeared in the journal PNAS, Perreault and fellow author Jonathan Paige, a University of Missouri anthropologist, explain how their analysis of stone tools dating back to 3.3 million years ago revealed this sudden and unexpected technological leap.

    The researchers analyzed tools collected from 57 separate ancient hominin sites. The oldest tool, dating back over 3 million years, came from an African site. However, the researchers also studied ancient stone tools discovered at ancient hominin sites in Eurasia, Greenland, Sahul, Oceania, and the Americas.

    Next, the team ranked the tools’ complexity. This meant analyzing how many steps would need to be taken to create the tool in question. The researchers characterized and ranked 62 distinct tool-making sequences.

Levallois Core, Algeria. Museum of Stone Tools. LINK).

    After charting the tools’ complexity, the team saw some unexpected patterns. Tools made between 3.3 million years ago and 1.8 million years ago required somewhere between two and four procedural units to manufacture. The complexity of stone tools steadily increased over the next 1.2 million years, with the top samples requiring an impressive seven steps. While significantly more complex than tools made over a million years earlier, the researchers say this is still within the range of complexity for a single craftsman. This means knowledge from previous generations of toolmakers had most likely not been passed down over that span.

    However, the researchers discovered that when they looked at tools made around 600,000 years ago, in the Middle Pleistocene, they began to see a sudden and unexpected increase in complexity. Tools from this time period were not only more complex, but more complex manufacturing processes were required to make these tools.

    “We analyzed the stone tools made during the last 3.3 million years,” the researchers explain. “We found that these stone tools remained simple until about 600,000 B.P. After that point, stone tools rapidly increased in complexity.”

    Where previous tools had required only a handful of procedural steps to manufacture, tools from this time often required as much as 18 steps. According to Paige and Perreault, this is way too many steps for a single generation of craftsmen to achieve without the knowledge passed down from previous generations.

    This evidence, the researchers write, is consistent with findings from other research teams, suggesting that such a rapid transition “signals the development of cumulative culture in the human lineage.”

    “By 600,000 years ago or so, hominin populations started relying on unusually complex technologies, and we only see rapid increases in complexity after that time as well,” said Paige. “Both of those findings match what we expect to see among hominins who rely on cumulative culture.”

    Dawn of Cumulative Culture and the Evolution of Modern Humans

    Although the evolution of stone toolmaking provides evidence for the dawn of cumulative culture, the researchers behind the findings say such a leap likely affected all aspects of early humans. This likely included changes in human culture, biology, and even the ability to adapt to a range of environments and habitats found across the globe.

    “The human dependence on cumulative culture may have shaped the evolution of biological and behavioural traits in the hominin lineage,” Paige and Perreault explain, “including brain size, body size, life history, sociality, subsistence, and ecological niche expansion.”

    Such changes can increase in complexity as genetic and cultural evolution happen concurrently. According to the researchers, this “gene-culture coevolution process” may explain increases in relative brain size, a prolonged life history, “and other keystone traits underlying human uniqueness.”

    Notably, the researchers point out that the Middle Pleistocene shows many other examples of evolving technology. For example, studies of this era reveal consistent evidence of the controlled use of fire, hearths and other domestic spaces. This era also features the evolution of wooden structures constructed with logs hewn using hafted tools, which, the researchers explain, “are stone blades affixed to wooden or bone handles.”

    In their conclusion, Paige and Perreault note that toolmaking is just one measure of cumulative culture, and further study could spot other increases in this behaviour that may have occurred in the past but are not immediately evident in the archaeological record. “It is possible that early hominins relied on cumulative culture to develop complex social, foraging, and technological behaviours that are archaeologically invisible,” they write.

    Ultimately, the research team believes that their findings show how knowledge can be passed down through the generations without each successive generation having to rediscover the knowledge of the past. When enough knowledge makes it through, like what appears to have happened 600,000 years ago, this process can result in an ever-increasing and adaptive knowledge pool that allows for a consistent upward progression in cultural and technological evolution.

    “Generations of improvements, modifications, and lucky errors can generate technologies and know-how well beyond what a single naive individual could invent independently within their lifetime,” the researchers conclude. “When a child inherits her parent’s generation’s culture, she inherits the outcome of thousands of years of lucky errors and experiments.”

    “The result is, our cultures — from technological problems and solutions to how we organize our institutions — are too complex for individuals to invent on their own,” Perreault adds.

    U.S. Air Force and Lockheed Martin Test Advanced Mk21A Missile Reentry Vehicle Over the Pacific

    The United States Air Force (USAF) and Lockheed Martin have announced the successful completion of tests involving their future intercontinental ballistic missile reentry vehicle, the Mk21A.

    The planned test flight of the Mk21A vehicle took place over the Pacific Ocean on June 17, demonstrating a significant step forward in the development of future intercontinental ballistic missile (ICBM) technology.

    The unarmed reentry vehicle was launched from Vandenberg Space Force Base, California, aboard a Minotaur I rocket at 11:01 p.m. Pacific Time.

    In a press release, the American aerospace company said the test allowed engineering teams to evaluate several of the Mk21A’s technological capabilities and primary design components. The development of the Mk21A is part of a broader initiative that forms a critical component of the U.S. Air Force’s strategy to modernize its ICBM weapon systems.

    “Test launches like these are crucial for protecting our nation’s defense,” said Col. Mark Shoemaker, Commander of Space Launch Delta 30, in a statement following Monday’s launch.

    Presently, the Mk21A reentry vehicle represents the cutting-edge ICBM weapon technologies of the future, providing the basis for technologies that are already becoming integral to the U.S.’s deterrent posture.

    Jay Watson, vice president of Strategic Reentry at Lockheed Martin, said his company’s more than six decades of involvement in the development of aerospace systems has “demonstrated exceptional performance in reentry technologies and a pioneering digital engineering approach on this program from its beginning.”

    “We remain focused on delivering this capability for the warfighter as a trusted partner to the U.S. Air Force for ICBM reentry systems and modernization of the deterrent triad,” Watson said.

    Monday’s test was part of an Engineering and Manufacturing Development contract the aerospace company presently has with the Air Force Nuclear Systems Center, based at Kirtland Air Force Base, New Mexico.

    The company says that the data it collected during the test flight will provide potentially crucial information that it will use in the ongoing development and future testing of the Mk21A.

    Presently, the reentry vehicle’s development remains on schedule, with assistance from modelling and simulation and the implementation of advanced digital engineering capabilities that have helped Lockheed Martin maintain an economical approach to the system’s development.

    The Mk21A’s unique design includes the arming and fuzing subsystem and support elements, which contribute to ensuring the vehicle’s operational performance and overall effectiveness.

    “As global threats evolve, it’s essential to support these launches and maintain access to space to safeguard our nation,” Col. Shoemaker said following Monday’s launch.

    Lost ancient Greek temple found drawn in 2,500-year-old graffiti ...

    2,500-Year-Old Graffiti Points to Existence of a Lost Ancient Greek Temple

    Researchers have uncovered unique graffiti on Barako Hill near Vari, Attica that may indicate there once stood a massive ancient Greek temple or structure on Athen’s famous Acropolis that has since been lost to history. 

    According to a new study published in the American Journal of Archaeology, this ancient drawing, attributed to a shepherd named Mikon, depicts a building identified as “the Hekatompedon,” a term historically associated with large temples

    “Mikon is not otherwise known, but he was most likely a shepherd who made the graffito while grazing his flocks,” explained Janric van Rookhuijzen, an archaeologist and co-author of the study, in a recent article. “The version of the Greek alphabet used is very ancient, making it clear that the drawing was made as early as the 6th century BCE.”

    The graffito (a term sometimes used to describe a singular piece of graffiti) was found among over 2,000 ancient engravings on marble outcrops in the hills north and east of Vari. These engravings, typically created by local herders, include simple drawings of animals, ships, and buildings, as well as short inscriptions. The particular graffito in question looks like a building facade, showing at least five columns, and is accompanied by an inscription identifying it as “the Hekatompedon.” 

    The term “Hekatompedon” refers to a structure approximately 100 feet in length. In ancient Greek architecture, this term was often used to describe large temples. But, it also means something else.

    “The term is known to be the official ancient name of the famous temple dedicated to the Greek goddess Athena – later known as the Parthenon,” van Rookhuijzen explained. “It is likely that Mikon wanted to depict a building on the Acropolis of Athens.”

    However, the inscriber, Mikon, pre-dated the Parthenon by several decades.

    “Because the alphabet he used can be firmly dated to the 6th century BCE, the drawing must be at least 50 years older than the Parthenon, which was begun around 450 BCE,” van Rookhuijzen wrote.

    According to the researchers, they believe that the graffito likely depicts an archaic temple on the Acropolis of Athens, possibly the so-called Bluebeard Temple or the Gigantomachy Temple. These temples are thought to have stood on the Acropolis at the end of the sixth century BCE, but were destroyed by the Persians in 480 BCE.

    Utilizing high-resolution photographs and detailed sketches, the work of this long-dead shepherd was analyzed for the various letter forms, orthography, and layout to determine its authenticity. The team compared this drawing and writing style to other known examples, as well as other known architectural drawings and inscriptions from the area.

    Based on their research, they note this is the earliest written record of the term “Hekatompedon” being used to describe a large temple or building. Moreover, noting the style of the graffito, as it features lines for columns and a cross line that represents an entablature (the horizontal lintel that sits on top of the columns), the study argues that this was probably some kind of symbolic gesture of admiration for the temple.

    In simple terms, Mikon probably just dug big buildings, and shepherds and herders were notorious for their graffiti. The hill where this drawing was discovered is covered in ancient shepherd graffiti, including images of horses, boats, and, of course, ancient erotica. 

    “Why the shepherds produced so many graffiti is not known – it may have simply been a form of escapism during the dull moments of their job,” van Rookhuijzen mused.

    “However, the graffito made by Mikon shows how a small scribble may be the key to tackling the historical riddles behind one the world’s most iconic archaeological sites.”

    Mogelijke verklaring gevonden voor één van de meest raadselachtige radiosignalen die ooit zijn gedetecteerd: het Wow!-signaal
    © Scientias.nl

    Een koude waterstofwolk die plotseling oplicht door intense straling van een ster zou wel eens kunnen verklaren waar het signaal, dat onderzoekers al bijna 50 jaar in zijn greep houdt, vandaan kwam.

    In de jaren zeventig van de vorige eeuw speuren astronomen van het Ohio State University Radio Observatory de hemel af, op zoek naar radiosignalen afkomstig van buitenaards leven. En op 15 augustus 1977 gebeurt het ongelofelijke: astronoom Jerry Ehman onderzoekt de gegevens die de radiotelescoop heeft verzameld en ziet plotseling een krachtig, smalbandig radiosignaal. Het signaal trekt onmiddellijk zijn aandacht. In zijn enthousiasme omcirkelt hij het signaal en schrijft in de kantlijn het veelzeggende ‘Wow!’ erbij. En zo is het Wow!-signaal geboren.

    Wow!-signaal

    Al tientallen jaren zoeken astronomen naar radiosignalen die mogelijk van (intelligent) buitenaards leven afkomstig zijn. Maar tot nu toe zonder resultaat. Behalve dan dat ene mysterieuze radiosignaal: het beruchte Wow!-signaal. Hoewel het al bijna vijftig jaar geleden is, blijft het Wow!-signaal, dat slechts één keer is opgevangen en waarvan de oorsprong nooit is achterhaald, de gemoederen bezighouden. Het is zelfs één van de meest raadselachtige radiosignalen die ooit zijn opgevangen. De sterke intensiteit en smalle bandbreedte nabij de 1420 MHz waterstoflijn maakten het tot een mogelijk teken van buitenaardse intelligentie. Maar was dit signaal écht afkomstig van een buitenaardse beschaving, of is er misschien toch een andere verklaring voor?

    Wow! Aliens?

    Hoewel men ‘hoopte’ dat het Wow!-signaal van buitenaardse wezens afkomstig zou zijn, is er nooit bewijs gevonden dat het signaal daadwerkelijk (opzettelijk) door aliens is verstuurd. Belangrijkste tegenargument voor dat idee is wel dat het slechts eenmalig is opgevangen. Als aliens het radiosignaal uitzenden om contact te maken, zou je verwachten dat ze dat herhaaldelijk doen. “Een andere mogelijkheid is dat het signaal niet bedoeld was voor de aarde, maar ‘weg is gelekt’ uit de communicatie tussen een beschaving en één van diens ruimtevaartuigen,” vertelde amateur-astronoom Alberto Caballero eerder. Het is trouwens ook niet de eerste keer dat wordt gesuggereerd dat het signaal misschien helemaal niet van buitenaardse wezens afkomstig is. Zo verscheen er een paar jaar geleden nog een studie die suggereerde dat kometen de oorzaak van het signaal waren – iets wat overigens door veel wetenschappers direct alweer in twijfel werd getrokken.

    Om het Wow!-signaal te duiden, zijn onderzoekers het zogenoemde Arecibo Wow!-project, gestart; een ambitieus plan om naar soortgelijke signalen te zoeken in oude gegevens van het voormalige Arecibo-observatorium. Dit observatorium was één van de grootste en krachtigste radiotelescopen ter wereld. Van 2017 tot 2020 bestudeerde het team verschillende hemellichamen op frequenties van 1 tot 10 GHz met de beroemde 305-meter telescoop van het observatorium. In 2023 zette het project de waarnemingen voort met een 12-meter telescoop op 8 GHz, met een focus op rode dwergsterren die mogelijk bewoonbare planeten herbergen.

    Soortgelijk signaal

    En nu komen onderzoekers met groot nieuws. “Onze meest recente waarnemingen, uitgevoerd tussen februari en mei 2020, hebben soortgelijke smalbandige signalen nabij de waterstoflijn opgeleverd,” vertelt onderzoeker Abel Méndez. “Deze signalen waren overigens wel minder intens dan het oorspronkelijke Wow!-signaal.”

    Geen ‘hallo’

    Na analyse van de nieuwe gegevens, denken de onderzoekers dat het Wow!-signaal (helaas) geen ‘hallo’ van een alien was. Zo suggereert hun onderzoek dat het raadselachtige signaal is ontstaan door een bijzondere astrofysische gebeurtenis. Mogelijk is het signaal het gevolg van een plotselinge helderheid van een koude waterstofwolk door sterke straling van een tijdelijke bron, zoals een uitbarsting van een magnetar of een ‘soft gamma repeater’ (een astronomisch object dat af en toe, met onregelmatige tussenpozen van meerdere jaren, krachtige uitbarstingen van röntgen- en gammastraling produceert). Dergelijke zeldzame gebeurtenissen kunnen ervoor zorgen dat waterstofwolken tijdelijk veel feller stralen, wat de kortdurende aard van het Wow!-signaal zou kunnen verklaren.

    Koude waterstofwolken in de Melkweg zenden zwakke radiosignalen uit, zoals te zien op deze foto van het Arecibo-observatorium uit 2020. Een plotselinge helderheid van zo’n wolk, veroorzaakt door sterke straling van een andere ster, zou het Wow!-signaal kunnen verklaren. Afbeelding: Planetary Habitability Laboratory

    Buitenaards leven

    Deze hypothese verklaart niet alleen de unieke kenmerken van het Wow!-signaal. Het laat ook zien dat we voorzichtig moeten zijn om elk raadselachtige signaal meteen als een teken van buitenaards leven te bestempelen. “Ons onderzoek suggereert dat het Wow!-signaal waarschijnlijk de eerste keer was dat we een ‘maser-achtige’ emissie van de waterstoflijn hebben geregistreerd,” stelt Méndez. “Deze hypothese zou ons begrip van dergelijke signalen kunnen herdefiniëren en invloed kunnen hebben op hoe we in de toekomst naar buitenaards leven zoeken.”

    Sisser

    Al met al loopt het verhaal van het Wow!-signaal, als de onderzoekers het bij het juiste eind blijken te hebben, met een sisser af. De studie biedt namelijk een nieuwe, ‘natuurlijke’ verklaring voor het mysterieuze Wow!-signaal, dat onderzoekers al bijna 50 jaar in zijn greep houdt. Het team vermoedt zelfs dat de precieze bron van het Wow!-signaal – of soortgelijke signalen – kunnen worden opgespoord door te kijken naar de sterren en andere objecten in de buurt van koude waterstofwolken.

    Het betekent dat we nog altijd geen bewijs hebben gevonden voor het bestaan van buitenaards leven. Voorlopig lijken we dus nog steeds alleen te zijn in de uitgestrektheid van het universum.

    A rare landing on the south pole of the moon led to this scientific discovery

    There was once a magma-filled ocean on the south pole of the moon, scientists recently discovered after analyzing lunar soil that revealed ancient information about the moon's origin.

    The study of soil taken from a less-studied region of the moon suggests the presence of remnants of a former ocean of magma, according to a study published Wednesday in Nature.

    The researchers analyzed lunar soil extracted from high-latitude regions on the southern portion of the moon -- taken as part of the Chandrayaan-3 mission when India’s Vikram lander module made a historic touchdown near the south pole of the moon in August 2023. The mission is the southern-most landing that has ever taken place on the moon -- a difficult feat considering the lack of sunlight, which can create visibility and communication issues, Anil Bhardwaj, director of Physical Research Laboratory in Ahmedabad and co-author of the study, told ABC News. Most lunar landings, especially human landings, have taken place in the equatorial or low-latitude regions.

    The mission embarked the use of new technology -- a particle access spectrometer -- an instrument aboard the rover that was able to make observations and collect data very close to the lunar surface, M. Shanmugam, the lead engineer of the alpha particle X-ray spectrometer at the Physical Research Laboratory in Ahmedabad, told ABC News.

    The composition of the soil found on Vikram’s landing site is consistent with an ancient magma ocean, the authors conclude.

    When analyzing the soil, the researchers found a relatively uniform elemental composition among 23 measurements at various spots along the lunar surface, primarily containing the rock-type ferroan anorthosite. The spectrum of elements also included all of the major and minor elements of the presence of magma, including sodium, aluminum, magnesium, carbon, silicon, sulfur, potassium, iron, titanium, chromium and manganese, Bhardwaj said.

    The moon is believed to have formed after a body the size of Mars struck Earth about 4.24 billion years ago, Bhardwaj said. The material that formed as a result of the volatile impact was likely magma that was thrown into space that remained within the Earth's gravitational pull and eventually began forming a planetary-mass object.

    The magma ocean is likely to have existed for tens to hundred million years, Santosh Vadawale, a professor in the Physical Research Laboratory and lead author of the study, told ABC News.

    Researchers believed the magma disappeared as the moon cooled throughout its formation, hypothesizing that, less dense ferroan anorthosite floated to the lunar surface while heavier minerals sank to form the mantle during the cool-down -- forming the lunar highlands as a result of the floatation of lighter anorthositic rock.

    Previous research into the Moon’s geology has primarily relied on samples taken by missions to lunar mid-latitudes, such as the Apollo program, giving scientists a more nuanced look into the history of the moon's formation, according to the paper.

    While the lunar magma ocean hypothesis has existed for decades, ever since the Apollo mission placed humans on the moon in 1969, the new research has allowed researchers to confirm the evolutionary history of the moon from billions of years ago, Vadawale said.

    "Our next mission, we would like to try to go as close as possible to poles, where there are these permanently shadowed regions where there is water is supposed to be there," he said.
