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.

This is our new dog Kira, a cross between a water dog and a Podenko. She has been with us since February 7, 2024 and is busy winning our hearts. She is a sweet, affectionate dog who quickly adapted to us within a week. She is very quick and curious, a very different dog than Noleke.

    Inside the mystery of one of America's deadliest roads - as experts find 'evidence' of UFOs and portals at spot where 15 people have died

    A team of investigators have claimed to have discovered evidence of interdimensional portals under a bridge where a staggering number of drivers have been killed. 

    Ex-CIA agent Andy Bustamante and journalist Paul Beban, who delve into paranormal and extraterrestrial activity on their show Beyond Skinwalker Ranch, alleged that they found the cause of the mysterious motor deaths. 

    The bridge, found on the Miller Ranch in Colorado, has seen at least 15 drivers lose their lives, alongside 16 cattle mutilations across the past 25 years. 

    Using LIDAR ground laser technology, they claimed to find evidence of underground vacuums under the bridge that were highly strange.

    In fact, by the end of the episode, a 3-D model of the bridge constructed from the LIDAR had some points located completely underground - something the investigators say might be due to time-slowing anomaly. 

    A bridge nearby to the Miller Ranch in Colorado has seen over a dozen deaths just a short walk from mysterious cattle mutilations - which a team of investigators claim may be linked to secret 'portals' underground

    In the show, the team of investigators said the bridge at the ranch is 'one of the deadliest stretches of road in the country, and we just have no idea why.' 

    They claimed that after using LIDAR technology to survey the ground underneath the bridge, they potentially found 'portals' that could lead to another dimension. 

    The team also used electromagnetic pulses through the bridge, which they claim were interrupted by radio waves. 

    Describing the radio waves as 'data packets', they alleged that the frequent pulses may form part of an encrypted message from beyond. 

    'What's fascinating is that one is electrical energy, one is radio frequency, so there should be no relationship here,' one investigator pointed out. 

    The bridge came under scrutiny not only because of the high number of deaths, but also its proximity to the cattle ranch where a number of livestock have been mutilated. 

    At least 16 cattle have been killed and dismembered over the past 25 years, with no explanation. The cows are often found without any blood or tracks around them, missing organs and limbs that have been cut with neat precision.  

    The experiment came as part of the show's delving into the UFO-hotbed site Skinwalker Ranch in Utah, and claim that unexplained phenomena in other parts of the country are linked to the site.  

    Scientists found strange radio wave pulses emanating from the bridge when they ran electromagnetic current through it

    In another recent experiment at the Skinwalker Ranch, the group attempted to understand what is causing a radar blip in the middle of Utah wilderness where a number of 'UFOs' have been reported. 

    The ground penetrating radar (GPR) they used sends radio signals into the ground, but some are also sent up into the sky, enabling the detection of objects that might be lingering above.

    The team noted how in the past, when they were scanning the area using GPS, there were times when all data would suddenly be lost, and the GPS signal would give readings that were below the surface of the ranch.

    Although the team had been attempting to uncover an underground tunnel that may lie below, the scientists were perplexed when the data they received appeared to have been altered by an unknown force. 

    In a series of experiments at Skinwalker Ranch, the group used both ground penetrating radar and rockets, they try to determine what may also be causing the electromagnetic disturbance from above

    The testing at the ranch comes as Skinwalker Ranch has grown in infamy in recent decades, particularly due to eerie UFO sightings and cattle mutilations. 

    Rancher Terry Sherman, who bought the property in the '90s, has revealed several mysterious phenomena at the ranch, that spooked him so much that he eventually sold the property and moved his family of four away.

    In one instance, Sherman found several heads of his cattle mutilated after purchasing the land in 1996.

    Additionally, Sherman witnessed unexplainable encounters, one in which Sherman saw a wolf-like creature three times the size of a normal wolf.

    Another researcher saw an bizarre creature with piercing yellow eyes surveilling him from a tree, among other mysterious instances.

    The ranch later became the focus of Pentagon investigations into UFOs through programs like the Advanced Aerospace Threat Identification Program (AATIP).

    Guys I found this on May 9, 2024, but finally got my things unpacked so that I can make a video of it. There are two structures about 250 meters across in the center of this crater. If you want a clear focused screenshot, then watch this video carefully or you wont be able to get it. When you enlarge the map, NASA blurs and pixelates your image so it's no longer clear. In this video, I teach you how to beat that. 100% proof of intelligent life on Earths moon.

    Fragment van een papyrus met verhalen over Jezus' kindertijd ontdekt: het onthult nieuwe details

    Janine imageDoor Janine

    Biblioteca statale e universitaria di Amburgo

    Jarenlang bewaarde een bibliotheek in Hamburg, Duitsland, een oude papyrus, in de veronderstelling dat het een onbelangrijk document was. De waarheid is echter heel anders, althans volgens de twee experts die het fragment lange tijd hebben bestudeerd en de inhoud ervan hebben onthuld. Het zou de oudst bekende kopie zijn van een van de apocriefe evangeliën, die vertelt over de wonderen die Jezus verrichtte toen hij nog een kind was.

    Het oudste exemplaar van het Kindheidsevangelie van Thomas bevindt zich in Hamburg: niemand wist het

    We zijn in de Carl von Ossietzky Staats- en Universiteitsbibliotheek in de stad Hamburg, in Noord-Duitsland. Jarenlang werd gedacht dat een van de bewaard gebleven papyri niets anders was dan een alledaags document, een privébriefje of een boodschappenlijstje. In werkelijkheid, zeggen twee experts die de gelegenheid hebben gehad om het fragment van de papyrus te analyseren, zou het een van de belangrijkste documenten zijn om de eerste eeuwen van het christendom te begrijpen.

    De studie, gepubliceerd in de Journal of Papyrology and Epigraphy, beweert dat dit fragment de oudste kopie is die ooit is gevonden van het Kindheidsevangelie van Thomas. Terwijl de eerdere versie dateert uit de 9e eeuw, zou de papyrus die in Hamburg bewaard werd minstens 1600 jaar oud zijn en geschreven zijn tussen de 4e en 5e eeuw. Toch bewaarde de bibliotheek het document jarenlang en niemand realiseerde zich ooit het belang ervan, totdat prof. Lajos Berkes het woord “Jezus” in de tekst opmerkte. En hij besloot op onderzoek uit te gaan.

    Dit is wat de papyrus zegt over de kindertijd van Jezus

    Het fragment bevat 13 regels geschreven in het Grieks en komt uit het laat-oude Egypte, toen het christendom al een wijdverspreide en waarschijnlijk staatsreligie was geworden. Zoals bevestigd door de twee geleerden die de papyrus analyseerden, Lajos Berkes en Gabriel Nocchi Macedo, gaat de inhoud niet over boodschappen of andere alledaagse zaken. In plaats daarvan vertelt het een verhaal uit de kindertijd van Jezus dat bekend staat als het levend maken van mussen van klei.

    De episode is al bekend, omdat hij voorkomt in recentere kopieën van het Kindheidsevangelie van Thomas, en vertelt over het tweede wonder van de jonge Jezus. Op 5-jarige leeftijd is Jezus aan het spelen aan de oever van een rivier en maakt hij kleine musjes met klei. Jozef berispt hem omdat hij op een ongepaste dag werkt, waarop Jezus in zijn handen klapt en leven geeft aan de musjes, die wegvliegen van de rivier.

    Een deel van de apocriefe evangeliën

    Er wordt weinig gesproken over het Kindheidsevangelie van Jezus, dat wordt toegeschreven aan de apostel Thomas maar in werkelijkheid in de 2e eeuw is geschreven. Het is in feite één van de apocriefe evangeliën, teksten die zijn uitgesloten van de officiële bijbelse canonvorming van de Katholieke Kerk omdat ze vaak als onbetrouwbaar werden beschouwd of in ieder geval in tegenspraak zijn met de vier testamentaire evangeliën. Het Kindheidsevangelie vertelt bijvoorbeeld over een reeks wonderen die Jezus tussen zijn 5e en 12e levensjaar verrichtte, maar andere evangelies verzamelen gezegden, weer andere episoden uit het leven, enzovoort.

    Het belang van de Hamburgse ontdekking ligt niet alleen in de oudheid van het handschrift, dat hoe dan ook een essentieel element is. Naast dit aspect stelt het bestuderen van een papyrus uit de 4e tot 5e eeuw ons in staat de verspreiding van deze evangeliën in de eerste eeuwen van het christendom te begrijpen. De ontdekking schuift de oudste kopie van het Kindheidsevangelie van Thomas daarom niet simpelweg enkele eeuwen terug, maar biedt nieuwe informatie over de context van het kopiëren en bestuderen van deze teksten. Die toen al buiten de traditionele canon werden beschouwd, maar die ons op de een of andere manier hebben bereikt.

    Something’s Always Been Off About the Crab Nebula. Webb Has Revealed Why!

    The Crab Nebula has always fascinated me, albeit amazed me that it doesn’t look anything like a crab! It’s the result of a star that exploded at the end of its life back in 1054 CE, leaving behind what is known as a supernova remnant. Back then the explosion would have been visible to the naked eye, even in daytime. It was thought that the supernova that led to the cloud was from a less evolved star with a core made from oxygen, neon and magnesium. Recent studies by the James Webb Space Telescope reveals that it may actually be the core collapse of an iron rich star. 

    The Crab Nebula can be found in the constellation Taurus measuring 11 light years across. Deep inside the cloud, which expands at a rate of 1,500 kilometres per second, lies a rapidly rotating neutron star known as a pulsar. It emits a beam of electromagnetic radiation that sweeps across space much like a lighthouse sweeping out across the ocean. It has been the subject of many studies to learn about the dynamics of stellar evolution. 

    Previous studies have attempted to understand the total kinetic energy of the original explosion based upon the velocity of the expanding cloud. The data suggested that the supernova was relatively low energy so the progenitor star was likely to be in the range of 8 to 10 times the mass of the Sun. If it had been more massive it would have experienced a more violent supernova which would be revealed in higher velocity of the expanding gas cloud. But there was a problem. 

    The Fred Lawrence Whipple Observatory’s 48-inch telescope captured this visible-light image of the Pinwheel galaxy (Messier 101) in June 2023. The location of supernova 2023ixf is circled. The observatory, located on Mount Hopkins in Arizona, is operated by the Center for Astrophysics | Harvard & Smithsonian.
    Hiramatsu et al. 2023/Sebastian Gomez (STScI)

    The observations of the Crab Nebula, particularly the high rotational speed of the pulsar, seemed to conflict with current supernova theory. In the model for lower mass stars like that which was the progenitor star of the Crab Nebula, the oxygen in the core ignites as the core collapses. This process does not have sufficient energy to generate such a fast rotating pulsar. 

    A team of astronomers have addressed this curiosity using MIRI (Mid-Infrared Instrument) and NIRCam (Near-Infrared Camera) onboard the James Webb Space Telescope to collect data from the Crab Nebula. The team was led by Tea Temim from the Princeton University in New Jersey. They report that the gas composition of the cloud suggests the star may have been more evolved with some iron in the core which could have led to a higher energy supernova than previously thought.

    With Webb’s sensitive infrared instruments, the iron and nickel emission lines can be seen with more clarity than ever before. Studying the bright lines in the spectrum of the nebula has allowed a much more reliable estimate of the iron and nickel ratio to be deduced. They found it was a higher percentage compared to the Sun which was expected for a more energetic supernova. 

    The results are promising but the readings were taken from two small regions of the nebula so to rule out variations across the entire 11 light years further readings are needed. If the data from Webb is representative from the entire nebula then it’s possible one of the mysteries of the nebula may finally be solved.

    Lake Shorelines on Titan are Shaped by Methane Waves

    Distant Titan is an oddball in the Solar System. Saturn’s largest moon—and the second largest in the entire Solar System—has an atmosphere denser than Earth’s. It also has stable lakes and seas of liquid hydrocarbons on its surface.

    New research shows that waves on these seas are eroding Titan’s coastlines.

    The research is “Signatures of Wave Erosion in Titan’s Coasts,” and it’s published in Science Advances. The lead author is Rose Palermo, an MIT graduate and research geologist at the U.S. Geological Survey.

    In 2007, the Cassini spacecraft spotted lakes and seas of liquid hydrocarbons, mostly methane and ethane, on Saturn’s moon Titan. Titan and Earth are the only two bodies in the Solar System known to have surface liquids. Scientists have only Cassini data from Titan to work with, and they’ve been poring over the data in an effort to understand this strange world.

    The moon’s seas are one of the most intriguing features throughout the entire Solar System. But they’re difficult to observe because of the thick atmosphere. Researchers have wondered if waves shape the coastlines, but there are conflicting signs about the nature of the seas. They could be rough, or they could be smooth. A paper from 2014 suggested that transient features in Titan’s northern sea, Ligeia Mare, could be waves.

    But there’s no certainty.

    “We found that if the coastlines have eroded, their shapes are more consistent with erosion by waves than by uniform erosion or no erosion at all.”

    Rose Palermo, lead author, U.S. Geological Survey

    “Some people who tried to see evidence for waves didn’t see any, and said, ‘These seas are mirror-smooth,'” lead author Palermo said in a press release accompanying the research. “Others said they did see some roughness on the liquid surface but weren’t sure if waves caused it.”

    It seems likely that there would be waves on Titan. To investigate this question, researchers at MIT compared Titan’s shorelines to shorelines on Earth to see if they match.

    The seas and lakes on Titan look much like some on Earth. They appear to be flooded valleys and depressions. But scientists are uncertain if these bodies of water are eroding their coastlines like those on Earth. “Spacecraft observations and theoretical models suggest that wind may cause waves to form on Titan’s seas, potentially driving coastal erosion, but the observational evidence of waves is indirect, and the processes affecting shoreline evolution on Titan remain unknown,” the authors write in their paper.

    The problem is that there’s no reliable way to connect shoreline morphology directly to the mechanisms that shape it, even on Earth. To try to understand how erosion affects Titan’s coastlines, the researchers started with Earth. They examined how different coastal erosion mechanisms shape Earth’s coastlines, then applied the framework to Titan.

    There are basically two types of coastal erosion: wave-driven erosion and uniform erosion. Each type produces different coastlines.

    Wave erosion is driven by wind and produces a change proportional to the strength of the waves. Waves are usually stronger the farther they travel before they hit a coast. Wave erosion creates long, smooth stretches of coast where the coast is fully exposed and bays in protected areas where less erosion occurs. The distance the wind can blow to generate waves on a particular water body before striking a coast is called ‘fetch.’

    “Wave erosion is driven by the height and angle of the wave,” Palermo explained. “We used fetch to approximate wave height because the bigger the fetch, the longer the distance over which wind can blow and waves can grow.”

    Uniform erosion is different. It doesn’t rely on mechanical wave action. The compositional differences between Earth and Titan are apparent when it comes to uniform erosion. “Titan’s crust consists mainly of water ice, but its surface solids may also include heavy hydrocarbon molecules, such as benzene, that are soluble in liquid methane and ethane, such that the liquid lakes and seas may slowly dissolve the solid coasts of the north polar terrain,” the authors explain in their research.

    Over a long enough period of time, uniform erosion occurs at the same rate in all locations, producing distinct morphological features: shorelines that are generally smooth even inside bays with sharp headlands that punctuate them.

    “Here, we test the hypothesis that coastal erosion has shaped Titan’s seas by investigating whether coastline shapes are most consistent with wave-driven erosion, uniform erosion, or no coastal erosion,” the authors write.

    This figure from the research illustrates how the two types of erosion would shape shorelines. The images are based on simulated Titan landforms and shorelines. A shows the initial condition of Titan's water bodies, where rivers carved out channels, and rising seas flooded them. B shows the morphology that wave erosion would produce, where the erosion rate depends on fetch. C shows the morphology that Uniform erosion would produce, where the erosion is uniform in all locations. Darker blue indicates deeper water and lighter yellow indicates higher land.

    The different morphological features produced by wave-driven erosion and uniform erosion are obvious. Wave-driven erosion tends to smooth exposed sections of the coastline where fetch is large and preserve the coastline where fetch is small inside embayments.

    Uniform erosion is different. It widens embayments and smooths out small-scale roughness on the coastline regardless of fetch. Headlands are the exception, which sharpen into thick-necked points that stick out into the main basin.

    “We had the same starting shorelines, and we saw that you get a really different final shape under uniform erosion versus wave erosion,” said co-author Taylor Perron, Professor of Earth, Atmospheric and Planetary Sciences at MIT. “They all kind of look like the Flying Spaghetti Monster because of the flooded river valleys, but the two types of erosion produce very different endpoints.”

    “We found that if the coastlines have eroded, their shapes are more consistent with erosion by waves than by uniform erosion or no erosion at all,” Perron said.

    But these are just simulations, and they have to be tested rigorously. The team’s next step was to quantify these differences in the real world. The researchers explain that they “developed a technique focusing on local relationships between shoreline roughness and fetch area” to understand and quantify the differences. Specifically, they quantified what they call “roughness” to differentiate wave-driven erosion from uniform erosion. “Simply put, a lower roughness means a smoother stretch of shoreline compared to the rest of the lake, and a higher roughness means a comparatively rough stretch of shoreline,” they write.

    This figure from the research shows roughness and fetch area for two of Titan's seas: Kraken Mare and Ligeia Mare. C and D show roughness for each sea. E and F show the normalized fetch area, assuming waves are fetch-limited. Fetch-limited means waves continue to grow as long as the fetch length increases. G and H show normalized fetch area assuming a saturation fetch length of 20 km. That means that waves only grow up to a certain fetch length and then saturate. In that case, the system is saturation-limited, and the "fetch length in all directions is truncated to a maximum value." Image Credit: Palermo et al. 2024.

    The researchers say that “… shoreline roughness and normalized fetch area can be used to fingerprint wave-driven and uniform erosion and distinguish them from a coastline consisting only of flooded river valleys,” as shown in the first image.

    So, what does this all boil down to?

    “Our results suggest that the coastlines of Titan’s largest liquid bodies are most consistent with shorelines that have been modified by wave erosion and river incision,” the researchers write in their paper. They analyzed four coastlines and found a less than 5% probability of uniform erosion in a saturation-limited scenario and a less than 20% probability of uniform erosion in a fetch-limited scenario. That leaves wind-driven erosion as the most likely cause of erosion, which seems to confirm that Titan’s lakes and seas experience waves. “Therefore, our results suggest that the largest seas and lakes are not consistent with erosion by uniform processes (i.e., dissolution), as previously hypothesized for some of Titan’s landscapes,” they conclude.

    That’s the scientific way of presenting their results, and their paper is like part of a long conversation with other scientists. In the press release, they state their conclusion more plainly for the rest of us.

    “We can say, based on our results, that if the coastlines of Titan’s seas have eroded, waves are the most likely culprit,” said Perron, Professor of Earth, Atmospheric and Planetary Sciences at MIT. “If we could stand at the edge of one of Titan’s seas, we might see waves of liquid methane and ethane lapping on the shore and crashing on the coasts during storms. And they would be capable of eroding the material that the coast is made of.”

    “Waves are ubiquitous on Earth’s oceans. If Titan has waves, they would likely dominate the surface of lakes,” says Juan Felipe Paniagua-Arroyave, associate professor in the School of Applied Sciences and Engineering at EAFIT University in Colombia, who was not involved in the study.” It would be fascinating to see how Titan’s winds create waves, not of water, but of exotic liquid hydrocarbons.”

    The next step is to determine how strong Titan’s winds have to be to create coastal erosion. The researchers also hope to decipher which directions the wind is predominantly blowing from.

    “Titan presents this case of a completely untouched system,” Palermo said. “It could help us learn more fundamental things about how coasts erode without the influence of people, and maybe that can help us better manage our coastlines on Earth in the future.”

    It’s Not Just Rocks, Scientists Want Samples Mars’s Atmosphere

    Mars holds a very special place in our hearts. Chiefly because of all the other planets in the Solar System Mars is probably the place we are going to find some tantalising clues or maybe even evidence of prehistoric life. NASA Perseverance Rover has been trundling around the Jezero Crater looking for evidence that it was once hospitable to life. To that end it has not only been collecting rock samples but air samples too and scientists can’t wait to get their hands on them. 

    The Mars Perseverance Rover is part of NASA’s Mars 2020 mission. It launched on 30 July 2020 and landed in the Jezero Crater successfully on 18 February 2021. The site was picked because it’s a dried up river bed and if there is any evidence of ancient primitive life on Mars, it is a likely location. Perseverance is equipped with a host of instruments including a drone named Ingenuity to survey the planet.

    One exciting element of the mission is the collection of rock samples as part of the Mars Sample Return Campaign. Twenty four core samples have been collected to date and deposited on the surface ready for collection by a future mission. It’s not just rock samples that have been collected though. Known as ‘headspace’ there is air in the space around the rock samples and it is this that has got scientists excited. 

    Not only do the rocks hold secrets about Mars but the atmosphere does too. It’s an atmosphere rich in Carbon Dioxide but is expected to have trace amounts of other gasses  too. Information about the current climate can be gained from the trapped gasses but it’s also possible to learn about the evolution of the atmosphere through analysis of the rocks. There is one particularly important tube that has been filled entirely with gas from the atmosphere.

    With the sample sat on the surface of Mars potentially for many years, the gas trapped will interact with the rock in the sample tube. It will only be when the tubes are opened up when they arrive back here on the Earth that the interaction will cease. It’s hoped to understand more about the levels of water vapour near the Martian surface. 

    It isn’t just the water vapour that is of interest but the levels of trace gas too are of interest. Through analysing the gas samples we can tell if there are gasses like neon, argon and xenon which are non reactive gasses. Because these gasses do not react then there presence in the tube samples may suggest that Mars stated with an atmosphere. We know that it had a much thicker atmosphere in the past but we don’t know whether it has always been there or whether it developed later.  

    There are many benefits that will come from analysing the samples even, the prevalence of dust that will help future human exploration. As Justin Simon from NASA’s Johnson Space Center in Houston said “The gas samples have a lot to offer Mars scientists, even those who don’t study Mars would be interested because it will shed light on how the planet forms and evolves.”

    Existence of lost temple dedicated to the Greek goddess of war is discovered in 2,500-year-old graffiti

    Archeologists have discovered a lost ancient Greek temple dedicated to the goddess of war, after translating a newly found case of 2,500-year-old graffiti. 

    Among over 2,000 remnants of ancient Greek graffiti, one scholar has uncovered a diagram of this lost temple to Athena, ancient Greece's goddess of war and wisdom.

    The graffiti, which experts said was made by a shepherd or herder, depicts a now bygone temple on the very same site as Athens' historic, still-standing Parthenon.

    'The structure,' according to the University of Tennessee classics professor who made the discovery, 'is identified by its inscription as 'the Hekatompedon' and was produced by an individual named Mikon.'

    Hekatompedon was once the official ancient name for the temple to Athena, but it translates literally to '100-footer' in ancient Greek, a reference to the temple's size.

    Crucially, however, the alphabet used in this graffiti dates it back to the 6th century BC — at least 50 years before the construction of the Parthenon structure, also dedicated to Athena, even began.

    'Mikon's graffito supports the scenario that the Hekatompedon in the decree was an operational temple on the south side of the Acropolis,' classics professor Merle Langdon wrote in his new study, published in the American Journal of Archaeology.

    This earlier temple would have been dismantled, and many of its columns and other structures could have been reused, for the ancient Greek structures still standing atop the hill where the Parthenon rests today, within the Acropolis of Athens. 

    Translated from this ancient Greek alphabet, the engraved inscription simply reads 'the Hekatompedon [—] of Mikon,' according to Langdon who was the first to discover the graffiti.

    The professor noted that there are two possible temple 'candidates' known to archeologists that could match the diagram that Mikon drew in his graffiti.

    One nicknamed 'the Bluebeard Temple' by archeologists and another called 'the Gigantomachy Temple,' a neutral temporary term used while scholars still debate what the remnants of these historic structures might have once really been.

    The Bluebeard Temple, which is theorized to have been built on the north side of the Acropolis around the second quarter of the 6th century, was named by archeologists for a prominent three-headed serpent with a blue beard, found among in its ruins.

    The Gigantomachy Temple, also called the Old Temple of Athena by some scholars, dates back to roughly the same 6th century period. 

    It's remnants were also found on the Acropolis in Athens, but its exact original location is still debated by scholars.

    Langdon and his co-author, archeologist Jan van Rookhuijzen, said they would stop short of trying to definitively identify 'the drawn temple' any further, as 'the debate on the architectural history of the Archaic Acropolis has not come to a resolution.'

    Hekatompedon, ancient Greek for '100-footer,' was the official ancient name for the temple to Athena. But the alphabet used in this graffiti dates it back to the 6th century BC, over 50 years before construction on the Parthenon even began. Above, on the hill, the Parthenon today

    In other words, the complete history of the lost temple to Athena, that Mikon called 'the Hekatompedon' is still shrouded in mystery and remains yet to be written. 

    For years, the team has studied the 6th century BC sketches, scrawlings and graffiti made by the ancient Greek's in this region — drawings that include ships, horses, and 'erotic scenes.'

    'Why the shepherds produced so many graffiti is not known,' van Rookhuijzen wrote in an article at The Conversation, discussing he and Langdon's new study.

    'It may have simply been a form of escapism during the dull moments of their job.'

    The hill where Mikon's graffiti was located, along the north and east of Vari, Attica, is now a southern suburb of Athens. 

    The landscape has become a boon to scholars as it is literally covered in ancient shepherd graffiti.

    Langdon and van Rookhuijzen employed high-resolution photographs and detailed reproductions to analyze the long-dead shepherd's writing style, hunting for clues in his letter forms, handwriting, and spelling to better date and authenticate the find.

    The team compared the Mikon drawing and its writing style to other previously discovered architectural drawings and inscriptions from the wider Athens area.

    Mikon's sketch of the temple, they concluded is 'the earliest known testimony of admiration of the architecture of the Acropolis,' based on its faithful and favorable depiction of the structure's columns and roof-like entablature.

    They also noted that Mikon's graffiti is now the earliest recorded instance of a person using 'Hekatompedon' to mean a large temple or building.

    'Our occurrence is earlier than the 37 other known examples of this name in the Greek world,' the team wrote in their new study, 'including 12 from Attica.'

    But the ancient graffiti still has some mysteries left to decode, as the shepherd's inscription — made on the exposed marble of Vari's Barako Hill — has now suffered from over two millennia's worth of erosion

    'This impedes a full appraisal of both the drawing and the inscription,' the researchers noted, 'of which some letters are illegible.'

    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

    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.”

    James Fox UFO Landing At Holloman AFB

    Footage Of UFO Landing At Holloman AFB With Aliens Walking Out Exists, Producer Told James Fox

    There is a UFO/alien controversy surrounding Holloman Air Force Base in New Mexico, where one of three UFOs allegedly landed in May 1971. The incident has been recently discussed by “Moment of Contact” filmmaker James Fox, who says the full  video of the UFO landing exists, including the alien entities walking out of the craft.

    However, as it is so often in such cases, instead of the government releasing a film of the entire incident to author/filmmaker Robert Emenegger as promised, it only released 8 seconds of this special footage that ultimately made it into the film. Holloman Air Force Base is the United States Air Force base established in 1942 and located six miles southwest of the central business district of Alamogordo, New Mexico.

    The story begins in 1971 when Emenegger and producer/director Allan Sandler were invited by US intelligence to Norton Air Force Base in California to discuss the significant UFO phenomenon that had occurred previously and create a documentary film about it.

    Apparently, Mr. Fox recalls the Holloman incident on Julian Dorey Podcast, published on February 25, 2023. He says that he interviewed Sandler and Emenegger about it and they as well believe the UFO landing film footage exists. He points out this happened not far from Socorro, where Lonnie Zamora had his famous sighting roughly a year prior of a similarly shaped “tic tac” white craft and beings walking around the UFO.

    There is no official record of the reason why the US government allowed giving secret UFO footage for a documentary film. It is believed that the administration of President Nixon did it to look strong in the science field for the upcoming 1972 re-election campaign.

    Emenegger said that he was promised by the USAF officials to get the authentic UFO landing footage that happened at Holloman Air Force Base in New Mexico in 1971. It showed the alien visitors emerging out of the craft that met with the US military. Even though Emenegger was skeptical about it, the Air Force assured him that the footage was authentic.

    One of the military’s officials named Paul Shartle, who was in charge of the audio-video department, said in a 1988 national television broadcast with Mike Farrell that he had watched the 16mm film of three disc-shaped craft. One of them landed and the others flew away.

    “I saw footage of three disc-shaped crafts one of the crafts landed and two of them went away. It appeared to be in trouble because it oscillated all the way down to the ground. However, it did land on three pods, a sliding door open a ramp was extended, and out came three aliens. They were human-sized. They had an odd gray complexion and a pronounced nose. They wore tight-fitting jumpsuits, thin headdresses that appeared to be communication devices, and their hands in their hands they held a translator I was told.”

    Mr. Fox revealed on the podcast that Allan Sandler told him on the phone call that he had seen three discs escorted by a military jet. “He was not sure of the altitude, but he estimated that they were at roughly 10 to 12,000 feet,” Mr. Fox said. He continued: “Paul Shartle (One of the military’s officials at Norton Air Force Base in California who was in charge of the audio-video department) admitted that he had seen it and that it was not of Earth origin.”

    Sandler told Mr. Fox that two of the discs peeled away while one wobbled to the ground. He said it was like a leaf floating down from the sky, and it looked like it was in trouble. Mr. Fox said that the wobbling movement was similar to the footage he had seen of a UFO before. He does not think that Allan knew how the UFO hovered. The disc eventually went to the ground.

    “He said James, just like in a sci-fi movie, the seamless door opens and out come these beings that had very large noses, slits for mouths, and their eyes were almost like a vertical slit, like a cat’s eye, very, very big. They had… I’m just like… I [Fox] need to make this abundantly clear to your audience. I’m not saying what’s true or what’s not true, or if it happened or if it’s alien or whatever it is. I’m just telling you what I was told by people who saw it, and claimed to have seen it. They came out and they met with the base commanders, and then they either got into a Jeep or were about to get into a Jeep or do something and then the film footage just cuts.”

    Emenegger claimed that he personally visited the landing site and inspected the area where the extraterrestrial craft had been stored, and that the US military and the alien visitors had held meetings that lasted for several days.

    Additionally, Emenegger’s production team was granted access to highly classified documents at DoD facilities, and they received assistance from military officials who had expertise in UFO-related matters, such as Col. William Coleman of Project Blue Book and Col. George Weinbrenner, who headed Foreign Technology at Wright Patterson Air Force Base.

    Paul Shartle, who showed the footage to Allan Sandler, faced some men in dark suits that showed up from an unknown location and warned him not to speak of the incident. They confiscated the footage, stating that it was not supposed to have happened. Sandler did not inform Emenegger for over 40 years.

    Emenegger completed extensive research and film production only to feel cheated when the authorization to use real footage was withdrawn. Despite this setback, he went ahead and released his documentary “UFOs: Past, Present, and Future,” which was nominated for a Golden Globe in 1974. The documentary was groundbreaking because it provided information from the Department of Defense (DoD).

    The United States Air Force (USAF) required Emenegger to add animated footage of the alleged Holloman UFO landing. According to Emenegger, some frames from the original footage were used during the editing stage with USAF authorization, which was not entirely missing from the frames. The viewers spotted a genuine bright disc coming down slowly in the distance against the backdrop of Holloman’s surrounding landscape.

    David Cameron, a UFO researcher, shared in an interview that he was involved in confirming that the Pentagon was not covering up UFO sightings. He recounted the story of the Holloman Air Force Base film, where the government allowed producers to use eight seconds of footage of a landed alien ship in a documentary, but the classified part where an alien got out was removed.

    Mr. Fox explains that the point of the story is that there is compelling evidence of an event occurring involving an unidentified object and that there may be film footage of the incident. Despite the existence of this evidence, the story has been overshadowed by other sensational claims, such as secret meetings between President Eisenhower and aliens.

    While it is unclear what exactly happened, there is substance to the story and it should not be dismissed outright. However, the addition of other claims has muddied the waters and made it difficult to investigate the case of the president making contact with extraterrestrial life.

    ASTRONOMERS SAY THEY JUST WITNESSED A MASSIVE BLACK HOLE APPEAR OUT OF NOWHERE

    Astronomers using the Zwicky Transient Facility (ZTF) telescope in the US say they have witnessed a massive black hole appear out of nowhere.

    The incident occurred back in December 2019, when astronomers who were observing a distant galaxy they termed “unremarkable” suddenly began to increase in brightness rapidly.

    “Imagine you’ve been observing a distant galaxy for years, and it always seemed calm and inactive,” explained Paula Sánchez Sáez, an astronomer at ESO in Germany and lead author of the study accepted for publication in Astronomy & Astrophysics. “Suddenly, its [core] starts showing dramatic changes in brightness, unlike any typical events we’ve seen before.”

    Follow-up analysis by a host of the most advanced space observatories confirmed the incredible event while pointing to a likely culprit: a massive black hole lying at the heart of galaxy SDSS1335+0728, which is located 300 million light-years away in the constellation Virgo, had seemingly awakened from a long slumber and was devouring the gas in its immediate surrounding. This activity resulted in the massive and growing glow witnessed by astronomers.

    Of course, people in this field regularly observe unexpected changes in the cosmos. However, events like supernova explosions or other tidal disruption events which generate large amounts of light typically last for a very short time, ranging from a few days to a few hundred days, before their brightness runs out. In this case, the researchers behind the discovery say they knew something was different when the increase in brightness first spotted in 2019 not only persisted but began to increase over time.

    Since then, they have spent half a decade pouring through archived data collected by other space observatories, including the European Southern Observatory’s Very Large Telescope (ESO’s VLT), to search for an explanation. That analysis found that SDSS1335+0728 was emitting more light in the visible spectrum and ultraviolet, optical, and infrared wavelengths. Then, in February 2024, the galaxy started emitting X-rays. According to Sánchez Sáez, who is also affiliated with the Millennium Institute of Astrophysics (MAS) in Chile, such behaviour is “unprecedented.”

    The team followed up on their findings by studying archival data from NASA’s Wide-field Infrared Survey Explorer (WISE) and Galaxy Evolution Explorer (GALEX), the Two Micron All Sky Survey (2MASS), the Sloan Digital Sky Survey (SDSS), and the eROSITA instrument on IKI and DLR’s Spektr-RG space observatory. That work, along with supporting data collected by the Southern Astrophysical Research Telescope (SOAR), the W. M. Keck Observatory, NASA’s Neil Gehrels Swift Observatory and the Chandra X-ray Observatory, confirmed the original findings: astronomers had indeed witnessed a black hole appear out of nowhere.

    “The most tangible option to explain this phenomenon is that we are seeing how the [core] of the galaxy is beginning to show (…) activity,” says co-author Lorena Hernández García from MAS and the University of Valparaíso in Chile. “If so, this would be the first time that we see the activation of a massive black hole in real-time.”

    This artist’s impression shows two stages in the formation of a disc of gas and dust around the massive black hole at the centre of the galaxy SDSS1335+0728. The core of this galaxy lit up in 2019 and keeps brightening today — the first time we observed a massive black hole become active in real-time.

    “These giant monsters usually are sleeping and not directly visible,” added study co-author Claudio Ricci, from the Diego Portales University, also in Chile. “In the case of SDSS1335+0728, we were able to observe the awakening of the massive black hole, [which] suddenly started to feast on gas available in its surroundings, becoming very bright.”

    Hernández García says this process was so rare that it had “never been observed before.” Some previous studies had reported galaxies that were thought to be inactive suddenly becoming active, but this was the first time astronomers had seen it unfolding in real-time.

    While the team of astronomers admits they don’t exactly know what makes a black hole appear out of nowhere, they believe it is unlikely to be a one-time event. They even believe it could happen much closer to home, at the center of our own Milky Way galaxy.

    “This is something that could happen also to our own Sgr A*, the massive black hole (…) located at the centre of our galaxy,” said Ricci.

    Moving forward, the team says that additional observations and data analysis should shed even more light on their discovery. They also believe that collecting more data on SDSS1335+0728, which the Chilean-led Automatic Learning for the Rapid Classification of Events (ALeRCE) broker has classified as having an ‘active galactic nucleus’ (AGN), could benefit other researchers trying to understand the life cycle of black holes.

    “Regardless of the nature of the variations, [this galaxy] provides valuable information on how black holes grow and evolve,” Sánchez Sáez said. “We expect that instruments like [MUSE on the VLT or those on the upcoming Extremely Large Telescope (ELT)] will be key in understanding [why the galaxy is brightening].”

    Wetenschappers zien mogelijk een zwart gat wakker worden (en dat is een primeur)

    Artist’s impression: het sterrenstelsel SDSS1335+0728 licht op

    Eind 2019 begon het tot dan toe onopvallende sterrenstelsel SDSS1335+0728 plotseling helderder te stralen dan ooit tevoren. Om te begrijpen waarom, hebben astronomen gegevens van diverse instrumenten in de ruimte en op de grond, waaronder de Very Large Telescope (VLT) van de Europese Zuidelijke Sterrenwacht (ESO), gebruikt om bij te houden hoe de helderheid van het stelsel is veranderd. In een vandaag gepubliceerd onderzoeksartikel komen ze tot de conclusie dat ze getuige zijn van veranderingen die nog nooit eerder in een sterrenstelsel zijn waargenomen – waarschijnlijk als gevolg van het plotselinge ontwaken van het enorme zwarte gat in diens kern.

    Nog nooit zijn astronomen er getuige van geweest dat een zwart gat ontwaakt. Tot nu, zo lijkt.

    Want onlangs hebben onderzoekers mogelijk gezien hoe het zwarte gat in het hart van het verder heel onopvallende sterrenstelsel SDSS1335+0728 opeens actief werd. Dat is te lezen in het blad Astronomy & Astrophysics.

    Helderheidsverandering
    “Stel je voor dat je een ver sterrenstelsel al jaren waarneemt en dat het altijd rustig en inactief leek te zijn,” vertelt onderzoeker Paula Sánchez Sáez. “En dan begint zijn kern plotseling dramatische helderheidsveranderingen te vertonen – op een manier die je nog nooit eerder hebt gezien.” Het klinkt misschien als het begin van een spannende sciencefictionfilm, maar voor Sánchez Sáez en collega’s was het het begin van een opwindend onderzoek. Want de helderheidsveranderingen die de onderzoeker beschrijft, zagen zij in werkelijkheid plaatsvinden.

    Lastig te duiden
    En die helderheidsveranderingen waren in beginsel niet zo gemakkelijk te duiden. Want hoewel onderzoekers sterrenstelsels wel vaker zien oplichten – bijvoorbeeld door toedoen van een supernova-explosie of een tidal disruption event (waarbij een ster zich te dicht bij een zwart gat in de buurt waagt en uit elkaar wordt getrokken) – was de helderheidsverandering die SDSS1335+0728 onderging, duidelijk anders. Want waar een supernova of tidal disruption event de helderheid doorgaans enkele tientallen of hooguit honderden dagen beïnvloedt, duurde de helderheidsverandering in SDSS1335+0728 maar voort. Zelfs zo’n vier jaar nadat de onderzoekers de helderheid van het sterrenstelsel voor het eerst zagen toenemen, nam de helderheid nog steeds toe!

    Ongekend
    Ook spotten de onderzoekers nog niet eerder waargenomen helderheidsvariaties. Zo blijkt SDSS1335+0728 nu veel meer licht op ultraviolette, optische en infrarode golflengten af te geven dan een paar jaar geleden. En in februari van dit jaar begon het sterrenstelsel ook röntgenstraling uit te zenden. “Dit gedrag is ongekend,” stelt Sánchez Sáez.

    Primeur
    En eigenlijk is er maar één verklaring voor. Namelijk dat het zwarte gat in het hart van dit sterrenstelsel actief begint te worden. “Als dat inderdaad zo is, zou het voor het eerst zijn dat we een enorm zwart gat zien ontwaken,” stelt onderzoeker Lorena Hernández García.

    Zwarte gaten: hoe zit het ook alweer?
    Een zwart gat is een gebied in de ruimte waar de zwaartekracht zo immens sterk is dat niets – zelfs licht niet – eraan kan ontsnappen. Hierdoor zijn zwarte gaten volslagen donker en in feite dus onzichtbaar. Dat verandert echter als zo’n zwart gat ‘actief’ wordt, oftewel gas naar zich toe gaat trekken. En dat is wat onderzoekers in SDSS1335+0728 – een sterrenstelsel op zo’n 300 miljoen lichtjaar afstand – gezien denken te hebben. “In het geval van SDSS1335+0728 waren we er getuige van hoe het centrale zwarte gat zich plotseling tegoed begon te doen aan gas dat in zijn omgeving voorhanden was, waar het heel helder van werd,” legt onderzoeker Claudio Ricci uit. Dat gat verdwijnt namelijk niet direct in het zwarte gat, maar begeeft zich eerst in een baan rond het zwarte gat en vormt daar een zogenoemde accretieschijf. Het gas in zo’n accretieschijf wordt heel heet en begint te gloeien. Hierdoor neemt de helderheid van het sterrenstelsel waarin het zwarte gat zich bevindt, toe. Eerder hebben onderzoekers wel vastgesteld dat zwarte gaten die eerder inactief waren, actief zijn geworden. Maar tot voor kort waren ze nog nooit daadwerkelijk getuige geweest van het actief worden – of ontwaken – van een zwart gat.

    Hoewel de waargenomen helderheidsverandering van SDSS1335+0728 het beste te verklaren is door het feit dat het zwarte gat in het hart van dit sterrenstelsel is ontwaakt, houden de onderzoekers nog een kleine slag om de arm. En dat komt doordat er ook nog andere – maar wellicht minder plausibele – verklaringen denkbaar zijn voor de helderheidsverandering die SDSS1335+0728 ondergaat. Zo zou er bijvoorbeeld ook een ongekend traag verlopend tidal disruption event aan ten grondslag kunnen liggen. Of misschien wel een ander proces dat we op dit moment helemaal niet kennen. Vervolgwaarnemingen zijn dan ook nodig om met zekerheid te kunnen stellen dat onderzoekers zojuist – voor het eerst – getuige zijn geweest van het ontwaken van een zwart gat. “We verwachten dat instrumenten zoals MUSE van de VLT (Very Large Telescope, red.) of die van de komende Extremely Large Telescope (ELT) van cruciaal belang zullen zijn om te begrijpen waarom de helderheid van dit sterrenstelsel toeneemt,” zo stelt Sánchez Sáez.

    Alsof het nooit anders is geweest: wetenschappers geven mensen een extra duim - en die wennen daar vervolgens bizar snel aanpixel.

    Matched Twin Stars are Firing Their Jets Into Space Together

    Since it began operating in 2022, the James Webb Space Telescope (JWST) has revealed some surprising things about the Universe. The latest came when a team of researchers used Webb‘s Mid-Infrared Instrument (MIRI) to observe Rho Ophiuchi, the closest star-forming nebula to Earth, about 400 light-years away. While at least five telescopes have studied the region since the 1970s, Webb’s unprecedented resolution and specialized instruments revealed what was happening at the heart of this nebula.

    For starters, while observing what was thought to be a single star (WL 20S), the team realized they were observing a pair of young stars that formed 2 to 4 million years ago. The MIRI data also revealed that the twin stars have matching jets of hot gas (aka stellar jets) emanating from their north and south poles into space. The discovery was presented at the 244th meeting of the American Astronomical Society (224 AAS) on June 12th. Thanks to additional observations made by the Atacama Large Millimeter/submillimeter Array (ALMA), the team was surprised to notice large clouds of dust and gas encircling both stars.

    Given the twins’ age, the team concluded that these may be circumstellar disks gradually forming a system of planets. This makes WL 20S a valuable find for astronomers, allowing them to watch a solar system take shape. As noted, the Rho Ophiuchi nebula has been studied for decades by infrared telescopes, including the Spitzer Space Telescope and the Wide-field Infrared Explorer (WISE), the Infrared Telescope Facility (IRTF) at the Mauna Kea Observatory, the Hale 5.0-meter telescope the Palomar Observatory, and the Keck II telescope.

    Infrared astronomy is necessary when studying particularly dusty nebulae since the clouds of dust and gas obscure most of the visible light of the stars within them. Thanks to its advanced infrared optics, Webb was able to detect slightly longer wavelengths using its MIRI instrument. Mary Barsony, an astronomer with the Carl Sagan Center for the Study of Life in the Universe (part of the SETI Institute), was the lead author of a new paper that describes the results. As she related in a recent NASA press statement.

    Our jaws dropped. After studying this source for decades, we thought we knew it pretty well. But we would not have known this was two stars or that these jets existed without MIRI. That’s really astonishing. It’s like having brand new eyes.

    Radio telescopes are another way to study nebulae, though they are not guaranteed to reveal the same features as infrared instruments. In the case of WL 20S, the absorbed light was visible in the submillimeter range, making ALMA the ideal choice for follow-up observations. However, the high-resolution mid-infrared data was needed to discern WL 20S as a pair of stars with individual accretion disks. This allowed the team to resolve stellar jets composed of ionized gas that is not visible at submillimeter wavelengths.

    The power of these two telescopes together is really incredible. If we hadn’t seen that these were two stars, the ALMA results might have just looked like a single disk with a gap in the middle. Instead, we have new data about two stars that are clearly at a critical point in their lives, when the processes that formed them are petering out.”

    The combined MIRI and ALMA results revealed that the twin stars are nearing the end of their formation period and may already have a system of planets. Future observations of these stars with Webb and other telescopes will enable astronomers to learn more about how young stars transition from formation to their main sequence phase. “It’s amazing that this region still has so much to teach us about the life cycle of stars,” said Ressler. “I’m thrilled to see what else Webb will reveal.”

    Astroscale Closes Within 50 Meters of its Space Junk Target

    Space debris is a major problem for space exploration. There are millions of pieces up there in orbit from flecks of paint to defunct satellites. It is a known challenge to space exploration creating a shell of uncontrolled debris which could cause damage to orbiting craft or astronauts. A team at Astroscale have a spacecraft in orbit whose singular purpose has been to rendezvous with a defunct Japanese upper-stage rocket module. On arrival it is to survey the debris to test approach and survey techniques to ultimately inform how we can remove them from orbit.

    Space debris, or space junk, is exactly what it says; pieces of human made objects orbiting Earth that are no longer required. It’s not just unwanted items though, many pieces are the result of collisions and at speeds in excess of 28,000 kilometres per hour they pose a real threat to astronauts and operational spacecraft in low earth orbit.

    Taking a bleak view, NASA scientists Donald Kessler proposed a scenario where the shear volume of debris is high enough that collisions could cascade into a chain reaction. The chain reaction of collisions could ultimately lead to an exponential growth in debris and even cut off our access to space. It may seem a pessimistic view but some computer modelling of the scenario does give strong indications that this may be the case if we don’t act now.

    There have been numerous, almost fanciful ideas proposed from great big balloons covered in sticky stuff like giant fly paper in orbit to pickup bits and bobs floating around. Nets have also been proposed even lasers to piece by piece destroy the offending objects. If I were a betting man I would go for something along the lines of a net travelling through space at similar velocity, scooping up the debris and controlling its gentle deorbit until either landed safely for collection or burnt up in the atmosphere. 

    The ideas are there, what we are lacking, is data to assess their feasibility. Enter Astroscale, a company that was founded in 2013 and develops in-orbit solutions. They have been selected by the Japan Aerospace Exploration Agency – JAXA – for the first phase of Commercial Removal of Debris Demonstration. The purpose to demonstrate how the technology for removing large pieces of debris. This has led to the development of ADRAS-J (Active Debris Removal by Astroscale-Japan.)

    ADRAS-J was launched on 18 February and started its rendezvous phase four days later. On 9 April it began its approach from a few hundred kilometres and from 16 April it began its automated relative navigation approach taking it to within a few hundred metres using the onboard infrared camera. On 23 May it approached to 50 metres, a first for any spacecraft to arrive in such proximity to a large piece of debris. 

    The item is the upper stage of a Japanese rocket that measures 11 metres long and 4 metres in diameter. Now the two are so close, ADRAS-J will demonstrate proximity operations and collect images of the rocket to assess its movements. This is a particularly interesting object for ADRAS-J to study becausey it has no technology or infrastructure to enable docking or servicing so is a challenging piece of debris to remove.

    Wetenschappers knoeien met DNA van beerdiertjes om te achterhalen hoe ze aan hun superkrachten komen

    A tardigrade, or water bear.

    En als we meer leren over hoe beerdiertjes extreme omstandigheden kunnen overleven, kan deze kennis worden toegepast in biomedische technologieën, zoals het behoud en transport van menselijke organen.

    Beerdiertjes zijn nagenoeg onverwoestbaar. Je kunt ze blootstellen aan extreme hitte, bevriezen, in een vacuüm plaatsen of zelfs volledig uitdrogen: het lijkt ze allemaal weinig te deren. Deze buitengewone eigenschappen maken beerdiertjes tot een fascinerend onderwerp voor onderzoekers, die niet alleen uit nieuwsgierigheid, maar ook vanwege de mogelijke toepassingen geïnteresseerd zijn in het ontrafelen van hun geheimen. En in een nieuwe studie richtten onderzoekers zich op de kern van hun bizarre eigenschappen: het genoom.

    Genoom

    We weten dus dat sommige soorten beerdiertjes extreem en ongewoon bestand zijn tegen omstandigheden die voor de meeste andere levensvormen fataal zouden zijn. De genetische basis van dit bijzondere vermogen blijft echter een mysterie. “Om de superkrachten van beerdiertjes te doorgronden, moeten we eerst begrijpen hoe hun genen werken,” legt onderzoeker Takekazu Kunieda uit. “Mijn team en ik hebben een methode ontwikkeld om genen te bewerken – toevoegen, verwijderen of overschrijven -, zoals je zou doen met computergegevens, bij de zeer tolerante beerdiertjessoort Ramazzottius varieornatus. Hierdoor kunnen we nu de genetische eigenschappen van beerdiertjes bestuderen, vergelijkbaar met de manier waarop we dat doen bij gevestigde laboratoriumdieren zoals fruitvliegjes of rondwormen.”

    CRISPR
    Het team paste een recent ontwikkelde techniek toe, genaamd direct parental CRISPR (DIPA-CRISPR), gebaseerd op de bekende CRISPR-genbewerkingstechniek (zie kader). Deze methode fungeert als een genetische scalpel om specifieke genen nauwkeuriger dan ooit te knippen en te wijzigen. DIPA-CRISPR heeft het vermogen om het genoom van nakomelingen van een doelorganisme te beïnvloeden en heeft eerder effectief gewerkt bij insecten. Nu pasten de onderzoekers deze techniek voor het eerst toe op een ander organisme. En met succes. Ramazzottius varieornatus, een volledig vrouwelijke soort die zich aseksueel voortplant, produceerde consequent nakomelingen met twee identieke kopieën van dezelfde bewerkte genen, waardoor deze soort ideaal is voor DIPA-CRISPR.

    Wat is CRISPR ook alweer?
    CRISPR staat voor Clustered Regularly Interspaced Short Palindromic Repeats en maakt onderdeel uit van een bijzonder efficiënt verdedigingsmechanisme dat bacteriën inzetten in de strijd tegen piepkleine virusdeeltjes (ook wel bacteriofagen genoemd). Deze virusdeeltjes kunnen een bacterie letterlijk kapot maken. Dat doen ze als volgt: ze klampen zich vast aan de bacteriële cel en pompen hun DNA naar binnen, waarna ze de bacterie gebruiken om zichzelf duizenden keren te kopiëren. Zodra dat gelukt is, laten de virusdeeltjes de bacterie uiteenspatten en gaan de duizenden kopieën op zoek naar andere bacteriën waarin ze dat trucje nog eens kunnen herhalen. Gelukkig voor de bacterie is deze in dit hele scenario niet weerloos; hij beschikt over een verdedigingsmechanisme dat CRISPR-Cas wordt genoemd en uit twee onderdelen bestaat. Het ene deel jaagt op vijandelijk DNA en het andere knipt dat DNA kapot. Jaren geleden kwamen onderzoekers tot de briljante conclusie dat dit bacteriële verdedigingsmechanisme ook gebruikt kan worden om specifieke genen in levende cellen uit te schakelen. Of ‘foute’ stukjes DNA op te sporen, weg te knippen en te vervangen door een alternatief stukje DNA. Kortom: CRISPR-systemen bieden ons een relatief gemakkelijke, snelle en bijzonder precieze manier om DNA te bewerken. En niet alleen DNA van virussen, maar ook in planten, dieren en mensen. Naar verwachting kan CRISPR in de toekomst worden ingezet om genetische ziekten, maar bijvoorbeeld ook retrovirussen die zich in het DNA ophouden – denk aan HIV – te bestrijden.

    Kortom, met behulp van de CRISPR-techniek hebben onderzoekers nu met het DNA van het beerdiertje geknoeid. En dat leverde direct genetisch gemodificeerde nakomelingen op. “We hoefden alleen maar de met CRISPR geprogrammeerde gereedschappen, die gericht waren op specifieke genen voor verwijdering, in het lichaam van een ouder te injecteren om gemodificeerde nakomelingen te verkrijgen,” legt onderzoeker Koyuki Kondo uit. “We konden ook genetisch gemodificeerde nakomelingen verkrijgen door extra DNA-fragmenten toe te voegen via injectie. Dit stelt ons in staat om nauwkeurig de genomen van beerdiertjes te bewerken. Op deze manier kunnen we bijvoorbeeld bepalen hoe individuele genen tot uiting komen of welke specifieke functies deze genen vervullen.”

    Een beerdiertje ontvangt een dosis CRISPR-gereedschappen om een van zijn genen te veranderen, evenals die van de eieren die het binnenkort zal produceren.

    Superkracht
    Door specifieke genen van beerdiertjes te bewerken, kunnen onderzoekers bestuderen welke van deze genen verantwoordelijk zijn voor de veerkracht van beerdiertjes en hoe deze veerkracht precies werkt. En de meest opmerkelijke ‘superkracht’ van Ramazzottius varieornatus, is dat deze soort langdurig extreme uitdroging kan overleven. Dit kan deels wordt toegeschreven aan een specifiek gel-eiwit in hun cellen. En dat heeft interessante implicaties. Zo geloven Kunieda en andere beerdiertjesonderzoekers dat het de moeite waard is om te bestuderen of een volledig menselijk orgaan ooit succesvol kan worden uitgedroogd en weer gehydrateerd zonder dat dit tot degradatie leidt. Als dit haalbaar blijkt te zijn, zou het een revolutionaire impact kunnen hebben op de manier waarop organen worden gedoneerd, getransporteerd en gebruikt tijdens chirurgische ingrepen om levens te redden.

    Al met al zijn onderzoekers er dus in geslaagd om het genoom van beerdiertjes te bewerken. En dat markeert een belangrijke doorbraak in ons begrip van de genetische basis van hun opmerkelijke overlevingsvermogen. Tegelijkertijd kan dit voor sommigen als ‘sciencefiction’ en manipulatie klinken. “Ik begrijp dat sommige mensen zich zorgen maken over genbewerking,” zegt Kunieda. “Maar we hebben de genbewerkingsexperimenten uitgevoerd onder strikt gecontroleerde omstandigheden en de genetisch bewerkte organismen veilig opgeslagen in een afgesloten compartiment. CRISPR kan een buitengewoon krachtig instrument zijn om het leven beter te begrijpen en om praktische toepassingen te ondersteunen die positieve veranderingen in de wereld kunnen teweegbrengen. Beerdiertjes bieden niet alleen inzicht in mogelijke medische doorbraken, maar hun opmerkelijke eigenschappen vertellen ook een fascinerend evolutionair verhaal. We hopen dit verhaal verder te verkennen door hun genomen te vergelijken met die van nauw verwante organismen, gebruikmakend van onze nieuwe DIPA-CRISPR-techniek.”

    More mummified 'alien corpses' uncovered as shock DNA tests 'prove they aren't human'

    Jaime Maussan, a Mexican journo and UFO boffin who reckons he's got the extraterrestrial cadavers, is on the hunt for Yank and Euro scientists to prove they're real.

    Two unearthed 'alien' mummies from Peru have sparked a firestorm of debate after x-ray and ultrasound data was revealed in March, with experts worried they might be ancient humans nicked by grave robbers.

    Jaime Maussan, a Mexican journo and UFO boffin who reckons he's got the extraterrestrial cadavers, is on the hunt for Yank and Euro scientists to prove they're real.

    Chatting to the Daily Mail, Maussan spilled the beans that more "analyses are being done", and he's taking the Peruvian Government to court for the rights to cart the bodies off to top-notch labs in the States.

    READ MORE: 

    Maussan, no stranger to controversy and having ruffled feathers for the best part of ten years, is floating the theory that these mummies could be alien-human "hybrids", with his team claiming the new finds are packing "30 percent unknown" DNA.

    But the sceptics aren't buying it, with history buff Christopher Heaney telling the Daily Mail: "Personally, I am not convinced that they are humanoid. I think they're human".

    Over the past twelve months, Maussan and his squad have been banging the drum for more scientific eyeballs on the remains, even causing a stir with a contentious showcase to Mexico's bigwigs in Congress and butting heads with Peru's Ministry of Culture.

    In April, the drama hit fever pitch when cops busted into a press conference hosted by Maussan in Peru, aiming to nick one of the bodies on show known as "Montserrat".

    Maussan let slip it's going to be an eight-month wait for any news on the courtroom front

    Now, Maussan is hitting back with a whopper of a lawsuit against Peru's government, demanding damages and the right to cart the strange specimens off to the States for some poking and prodding by independents.

    "The lawsuit is already in for $300 million (£235.5 million)," Maussan dished out to the Daily Mail.

    On his Sunday show "No Humano", Maussan let slip it's going to be an eight-month wait for any news on the courtroom front. This isn't about lining his pockets though, he's keen to splash the cash on a museum showcasing the mummies.

    Expert Claims Test On Roswell Metal Fragment Yielded Proof UFO Crash In 1947

    BY 

    pure aluminum

    I’m typically an extreme skeptic when it comes to evidence of extra terrestrial life on earth. But evidence from a new Discovery channel show has at least piqued my curiosity and bolsters the theory that a UFO crash landed in Roswell, New Mexico back in 1947.

    In a short clip released from the show (video below), they reveal that they tested the metal allegedly found at the crash in Roswell in 1947 which people have for generations claimed to be a UFO. The man on camera claims the test results came back as 100% aluminum.

    Why is this important? Because no matter how hard we’ve tried, humans have simply been unable to make 100% pure aluminum. We consider ‘pure aluminum’ to be 99% aluminum and our highest possible purity is 99.9999% but for aluminum to be 100% suggests it came from a UFO at Roswell.

    Skeptic as I am, I’m inclined to think that whatever test was used to evaluate this aluminum was highly accurate but probably not accurate enough to test out to the .0001%.

    Is it possible this is actually 100% aluminum? Sure. Is it more likely that the test simply wasn’t precise enough to detect that it was 99.9999% aluminum and not 100%? That seems more likely than it being a UFO.

    Furthermore, given that the Roswell UFO crash was all the way back in 1947, I’m inclined to think that (1) it’s highly unlikely those crash fragments still exist and (2) corrosion might be playing a role here but that’s just me throwing darts at the wall to see what sticks.

    There is an interesting Reddit thread where people posit other theories. The top comment also points out that it’s been 80 years and quite possible the military “pulled a switcheroo” between then and now. But there is also the option that is truly 100% aluminum and it came from a UFO. What do you all think? I’m inclined to think it’s 99.999% aluminum and the test was wonky.

    UFOs Are Invading Japan's Airspace—and Authorities Are Digging Deep to Find the Truth

    Do the aircraft come from foreign adversaries, or somewhere more extraterrestrial?

    • Japanese lawmakers will investigate sightings of so-called Unidentified Aerial Phenomena (UAP) taking place in the skies over Japan.
    • Japan is following the U.S. lead of conducting a government-level investigation into sightings.
    • The concern is that the sightings may be of Chinese aircraft intruding into Japanese airspace.

    Members of the Japanese government will investigate recent sightings of unidentified aerial phenomena (UAP), to determine if the sightings are credible. The group will work to determine if the spotted craft are in any way a threat to Japan’s security.

    While the Japanese group is open to exploring all sightings, their focus is very much on the possibility of earthbound threats, especially from neighboring China, rather than extraterrestrial ones.

    A High-Level Effort

    According to Jiji Press, the group consists of approximately 80 Japanese lawmakers, including the ruling Liberal Democratic Party’s parliamentary affairs leader, and three former defense ministers. The group, mostly drawn from Japan’s legislative body, or Diet, believes the UAP phenomenon is under-scrutinized by the government, especially in light of recent sightings of unidentified objects in and around Japan.

    The as-yet-untitled group has decided to include the term “unidentified anomalous phenomena” in its name. “UAP” is a term recently promulgated by the U.S. Department of Defense to differentiate its own investigative effort from past efforts to study unidentified flying objects, or UFOs, which have strong associations with flying saucers and possible extraterrestrial sightings.

    So far, the group lacks any direct government or agency support, like the Ministry of Defense or the Japan Aerospace Exploration Agency (JAXA), the Japanese equivalent of NASA. That said, as lawmakers, the investigators can approve spending to involve those agencies in UAP analyses.

    A New Threat?

    A television at Seoul’s Yongsan Railway Station displays news about North Korea conducting a drill to launch the Hwasal-2 strategic cruise missile off its west coast. A low-flying, subsonic cruise missile like Hwasal-2 could be mistaken for a UFO.

    Like most countries, Japan has traditionally not paid a lot of attention to UFO sightings. A number of factors have boosted awareness of UAPs: a number of high-profile sightings reported by U.S. military pilots, radar operators, and other personnel; the development of unmanned aerial vehicles, or drones; and China’s use of balloons to collect intelligence regarding foreign countries.

    The broad concern is that China or Russia could be behind the sightings. The greatest concern is that either country might have experienced a technological breakthrough that allows its aircraft to conduct aerial maneuvers that are impossible by today’s standards. In 2004, for example Navy personnel reported monitoring craft that could fly up to 7,200 miles an hour, faster than the fastest-known aircraft, and quickly changing altitude, going from 20,000 feet to 80,000 feet in a matter of moments. Any military aircraft capable of such maneuvers would have a decisive advantage over an American or Japanese aircraft.

    A Chinese spy balloon flies over Charlotte, North Carolina, February 2023, shortly before it was shot down.

    Another possibility is that a foreign power might conduct espionage against Japan using drones or balloons, and that sightings of such devices could be chalked up to sightings of alien craft—and as a result, not be taken seriously. A Chinese drone could literally operate in plain sight, with eyewitnesses ridiculed by the authorities, as it gathered sensitive intelligence about Japanese political, military, and economic targets.

    In 2020, the Ministry of Defense ordered the Self Defense Forces to create a reporting protocol for UAPs. In February 2023, shortly after a Chinese spy balloon flew over the United States, the Japanese government reported that three previous sightings of unidentified flying objects were “strongly suspected” to have been of Chinese origin. The sightings, in 2019, 2020, and 2021, took place across Japan and involved overflying Japanese airspace, a breach of international law under the Chicago Convention on International Aviation.

    After the incidents were made public, Japanese Defense Minister Yasukazu Hamada told the press that the Self-Defense Forces, Japan’s armed forces, will be allowed to use weapons, including air-to-air missiles, in dealing with craft that violate Japanese airspace. In 2021, the Asahi Shimbun reported that members of the Air Self Defense Force had on at least two occasions reported seeing unusual flying craft.

    An SM-3 missile is launched from the Japan Maritime Self-Defense Force destroyer JS Kirishima, October 2010. The SM-3 is capable of intercepting targets in low Earth orbit.

    Japan is an island archipelago of 14,125 islands, and relies on air and sea routes for trade with the outside world. It also imports most of its food and energy from abroad, vital to keeping the world’s fourth largest economy humming. As a result, Japan maintains strong air and naval forces to keep those routes open, and its alliance with the United States means it has a powerful partner against aggressive neighbors such as China, Russia, and North Korea.

    The Self Defense Forces of Japan are some of the most technologically advanced in the world. Japan is set to purchase 147 F-35 Lightning II fighter jets, which will be the second largest F-35 fleet outside of the United States. Meanwhile, the two countries co-fund the SM-3 exoatmospheric ballistic missile interceptor, which shoots down incoming missile warheads, and Japan operates what is generally considered the most advanced non-nuclear powered attack submarines in existence, the Taigei class. Japan is also set to double its spending on security, including defense spending, by 2027.

    All of that spending is focused on countering known, specific threats, such as North Korean Hwasong ballistic missiles, Chengdu J-20 fighters of the Chinese Air Force, and missile submarines of the Russian Navy. If, like the balloons that flew over Japan from 2019 to 2021, there are other threats that are being reported, but disregarded because they are catalogued as “UFOs”, that creates a blind spot for the Self Defense Forces that an adversary can continue to exploit.

    As UAP study group chairman and former Defense Minister Hamada said, “Leaving something unknown is a problem for national security.”

    The new Japanese effort to study UAPs is several steps behind the United States, whose All-Domain Anomaly Resolution Office, or AARO, is currently investigating UAP sightings. Like the U.S., Japan is more interested in the possibility of enemies from China piloting mysterious craft instead of little green men from Mars.

    Now this is a report released by NUFORC. An object similar to what I found years ago...the world calls my discovery the Black Knight Satellites in the NASA index. Well, this looks just like one of the ones I found. The silver metallic reflections also indicate a metal hull of the craft. The evidence is building up more and more by the day.

    Eyewitness states:
    A black winged like object started to the west that appeared to be just above the tree line. At first it looked liked a floating balloon or some kind of large bird circling. Then we noticed 3 flashing lights on the object that flashed in sequence. As it drifted and spun it gained altitude as it moved to the east over Charlotte, NC. It passed the flight path of incoming planes to the Charlotte airport. It drifted much higher and out of sight to the east over Charlotte. Even though it looked to be spinning and drifting it traveled very high and very far quickly. We recorded a video.

    From UFO Disclosure to UAP Transparency: Richard Dolan Explores the Evolution

    Richard Dolan, a prominent UFO historian, delves into the evolving terminology and its implications in his insightful analysis on “The Richard Dolan Show.” The shift from “UFO” to “UAP” and from “Disclosure” to “Transparency” is more than mere semantics; it reflects broader societal and institutional attitudes toward these phenomena and attempts at narrative control.

    The Evolution of Terminology

    In the early days of UFO sightings, the term “flying saucers” was commonly used. This term carried connotations of science fiction and public hysteria, which often overshadowed serious investigations. Over time, the term evolved to “unidentified flying objects” (UFOs), a phrase coined by the United States military to bring a veneer of scientific objectivity and bureaucratic stability to the study of these phenomena.

    In recent years, however, there has been a notable shift toward the term “unidentified aerial phenomena” (UAP) and more recently, “unidentified anomalous phenomena.” This transition reflects an ongoing effort to rebrand and destigmatize the subject, making it more palatable for scientific study and public discussion. Dr. Richard Haynes, a NASA scientist and active UFO researcher, is credited with popularizing the term UAP in the 1990s, aiming to strip away the cultural baggage associated with UFOs and encourage serious investigation.

    From Disclosure to Transparency

    For decades, the UFO community has championed the concept of “disclosure,” which implies a revealing of hidden or secret information about UFOs by an established authority, often envisioned as a dramatic, definitive revelation by the President or another high-ranking official. This notion of disclosure suggests a moment of truth, where the existence and nature of UFOs would be laid bare for public scrutiny.

    In contrast, the term “transparency” has recently come into vogue, particularly in political and military circles. Transparency implies an ongoing process of openness and accountability but lacks the promise of a complete or final revelation. This shift from “disclosure” to “transparency” can be seen as a form of virtue signaling, providing a semblance of accountability while still allowing those in power to control the narrative and the extent of information released.

    The Role of Language in Shaping Perception

    Dolan emphasizes the power of language in shaping public perception and controlling narratives. He draws parallels with George Carlin’s critique of “soft language,” which dilutes the truth and makes serious issues seem less immediate and real. Similarly, George Orwell’s exploration of political jargon and euphemisms in “Politics and the English Language” highlights how language can obscure harsh realities and manipulate public thought.

    The rebranding of UFOs to UAPs and the shift from disclosure to transparency can be seen as modern examples of these linguistic strategies. By changing the terminology, authorities can influence how the public perceives and discusses these phenomena, often reducing the urgency and altering the nature of the conversation.

    Implications for the Future

    While the shift to UAP and the emphasis on transparency have opened the door to broader discussions and bipartisan support in Congress, they also come with potential pitfalls. The term UAP encompasses a wide range of phenomena, including any airborne objects that cannot be immediately identified. This broad definition can dilute the focus on truly unexplained phenomena and make it easier for authorities to dismiss or downplay significant sightings.

    Moreover, the promise of transparency without the commitment to full disclosure may lead to continued obfuscation and control of the narrative. As Dolan notes, the institutional structures that have grown around the UFO secret over the past 80 years are deeply entrenched, involving significant financial interests and powerful players. Genuine disclosure, if it ever comes, is likely to be disruptive and challenging to the status quo.

    In conclusion, Richard Dolan’s analysis on “The Richard Dolan Show” sheds light on the significant shifts in language and terminology surrounding UFOs and UAPs. Understanding these changes is crucial for anyone interested in the study of unidentified phenomena and the broader societal and institutional forces at play. The transition from UFO disclosure to UAP transparency reflects deeper efforts at narrative control and highlights the ongoing challenges in achieving true openness and understanding in this enigmatic field.

    Fragmented Facts: AARO Report Unearths Odd Claims Involving U.S ...

    FRAGMENTED FACTS: AARO REPORT UNEARTHS ODD CLAIMS INVOLVING U.S. RECOVERY OF MATERIAL FROM 1952 UFO INCIDENT

    During the summer of 1952, the United States was on high alert as UFO sightings over the nation’s capital were making frequent headlines. Buried amid the otherworldly clamor occupying the minds of Americans around that time, an obscure report conveyed that one of the objects—a small, glowing disc—was pursued and shot at by a military aircraft, blasting off a fragment that fell into a field near Washington D.C., which a naval officer later retrieved.

    More than a decade later, an official government-funded scientific inquiry into UFOs—or what the United States government now calls unidentified anomalous phenomena (UAP)—would investigate the incident, ultimately determining claims involving the 1952 UFO incident were unlikely to be true.

    Without question, the notion that a fragment might have been recovered after a shoot-out with a flying saucer in the 1950s offers a textbook example of what most would call a dubious claim. Yet a deeper look into this Cold War-era rumor reveals, surprisingly, that there could potentially be more to this odd story than past assessments would seem to indicate.

    However, you would never have gleaned that from reading the latest report issued by the U.S. Defense Department’s official UAP investigative office.

    Last week, the All-domain Anomaly Resolution Office (AARO) released a long-awaited historical report on its findings involving the United States government’s involvement with UAP and related programs since the end of World War II.

    In the report, AARO investigators maintained the U.S. federal government’s longstanding position that it has never found any convincing evidence of extraterrestrial technologies operating near Earth, nor of any secret programs involving the acquisition or reverse engineering of crashed exotic technologies that have remained hidden from Congress.

    The report was met with heavy criticism following its publication, partly due to a number of errors it was revealed to contain. Despite this, there were also a few intriguing inclusions made by AARO’s investigators, based on their relevance to the question of whether UAP materials have ever crashed on Earth and been studied.

    One of these appears in a section of the AARO report that discusses the University of Colorado UFO Project, more commonly called the Condon Committee, a U.S. Air Force-funded evaluation of cases that were collected under its long-running Project Blue Book investigations that studied UFOs during the 1950s and 1960s.

    According to AARO’s recent report, the Colorado scientific panel, led by American physicist Edward U. Condon, “investigated a claim made by radio broadcaster Frank Edwards in a 1966 book that a piece of a UFO was recovered near Washington, D.C. in the summer of 1952 during the spike in UFO sightings over the U.S. Capitol in July and August.”

    The account in question appeared in Edwards’ book Flying Saucers: Serious Business, of which AARO’s investigators recount that Edwards “claimed that a USN jet fired on a two-foot diameter glowing disc and dislodged a one-pound fragment that was recovered by a ground team.” At the time of their study, the Condon Committee’s investigators inquired about the incident with Project Blue Book, who told the University of Colorado team that they were unaware of the purported 1952 incident.

    Frank Edwards

    Above: Excerpt from Frank Edwards’ 1966 book, Flying Saucers: Serious Business, where the author discussed the alleged 1952 UFO incident.

    “The USAF and USN found no incident report of weapons engagement with a UFO that summer, no USN aircraft were present, and the retired officer who was the original source of the claim had retired before the summer of 1952, when the event allegedly occurred,” the AARO report’s summary reads.

    The report then attributes another claim to Edwards, this time involving fragments from a UFO that were loaned by the United States to the Canadian government. “It is not clear if this claim was linked to the alleged Washington, D.C. incident,” the AARO report’s authors state, adding that “The Condon panel determined that these claims most likely were false.”

    The reason any connections between the 1952 UFO incident and Frank Edwards’ claims of a flying saucer fragment being loaned to the Canadian government remained unclear to AARO’s investigators is probably very simple. In likelihood, their investigation of these claims took them no further than the Condon Committee’s report (as evidenced by the relevant source citations found at the end of AARO’s document). Indeed, the two events are connected, as a deeper examination of the literature regarding this alleged 1952 incident readily reveals.

    Additionally, much like other assertions that appeared in the recent AARO report, some of the facts about this case have been misrepresented. However, this may not be entirely the fault of AARO’s team in this instance; a closer look at this case also reveals how much of the confusion arises from the Condon Committee’s original investigation, and problems involving their main source for the claims.

    THE CONDON COMMITTEE’S CONFUSION

    In the late 1960s, under contract No. 44620-67-C-0035 with the United States Air Force, the University of Colorado conducted an extensive analysis of UAP incidents collected by Project Blue Book, which resulted in the publication of its findings in a lengthy report titled Scientific Study of Unidentified Flying Objects.

    Despite the title of the Condon Committee’s report, many viewed it as being anything but a truly scientific evaluation of existing data on aerial mysteries. As British physicist Peter Sturrock later noted in his analysis of the Condon Committee’s findings, “most case studies were conducted by junior staff, the senior staff took little part, and the director took no part, in these investigations.” Additionally, after concerns were raised by some of the Committee’s members over apparent biases and other issues they identified with its leadership, several either resigned or were dismissed, resulting in the final report being partly assembled by staff who had only joined the project as it neared completion.

    Condon Committee

    Above: Original title from John G. Fuller’s article, “Flying Saucer Fiasco,” published in Look Magazine, May 14, 1968

    The saga of the 1952 UFO shoot-down over Washington was addressed in a section of the Condon Committee’s final report titled “Parts of UFOs, or UFO Equipment,” where the Colorado team’s investigators wrote that “Representatives of Air Force Project Blue Book claimed no knowledge of the disc fragment discussed by Edwards, who claimed the successful search for this fragment was confirmed by Lt. Cdr. Frank Thompson of the U.S. Navy.”

    “The fragment, said to have been dislodged by gunfire from a Navy jet, reportedly fell to the ground, where it was found, still glowing, an hour later by U.S. military ground search crews,” the Committee’s report states. “Reports of UFO events over Washington, D.C., in 1952 contain no reference to such a gunfire incident,” they add, though noting that had the fragment ever really existed “and was classified ‘Secret’ as was claimed, its existence and whereabouts would not necessarily be revealed to this project.”

    On the outside chance that such an incident might have occurred, the Committee’s members reached out to U.S. Air Force headquarters for clarification. A response came from J.W. Clinton “by direction of the Chief of Information, Department of the Navy,” who indicated that a search of all Navy records revealed no documentation related to the purported incident, nor could they find any records involving the retrieval of fragments at any time that were believed to have come from a UFO.

    That wasn’t the only damning revelation that came from a search of the Navy’s records. “Perhaps more significant, however, were the facts that Navy records of the year 1952 carried only one Frank Thompson, an individual who had retired from active duty several years before 1952 with the rank of lieutenant, not lieutenant commander,” the Condon Committee’s report states. In addition to this, the Committee’s investigators were told that it was unlikely that U.S. Navy aircraft would have participated in any shoot downs of objects over the nation’s capital, since in doing so they “would have been usurping an Air Force function if they had been present over Washington, D. C., as interceptors.”

    “The incident is not beyond the realm of possibility,” Clinton nonetheless conceded to the Colorado team, though ultimately concluding that the incident was “very highly unlikely” given the jurisdictional issues limiting any Navy aircraft’s involvement.

    Although Clinton had admitted that the incident reported by Edwards might at least have been possible, the fact that there had been no evidence of a “Frank Thompson” with the rank of lieutenant commander in active service at the time seemed to pour cold water on Edwards’ claims.

    However, a closer look at Edwards’ sources for this account reveals something that may help to clarify the matter, since it turns out the name of the Lieutenant Commander in question was not “Frank Thompson” at all.

    In the relevant chapter of Flying Saucers: Serious Business, Edwards states that one of his sources regarding the 1952 affair had been an earlier book from 1955 by Major Donald E. Keyhoe, titled The Flying Saucer Conspiracy. In Edwards’ book, he even provides the page number (272) for Keyhoe’s account of the incident, a review of which helps to shed some light on the situation.

    “I also listed a recent report given me by Lieutenant Commander Frank Thomas,” Keyhoe wrote in his brief account of the 1952 incident, immediately revealing that the “Frank Thompson” Edwards had been referencing was, in fact, instead a Lieutenant Commander Frank Thomas.

    1952 UFO

    Above: Excerpt from Donald Keyhoe’s 1955 book, later cited by Frank Edwards, where the actual name of Keyhoe’s source is shown as “Frank Thomas.” Edwards mistakenly wrote this individual’s name as “Frank Thompson” in his 1966 book.

    “According to Thomas, a peculiar object had fallen near Washington during the mass saucer sightings in 1952,” Keyhoe writes. “Retrieved by a naval officer, it was later analyzed by the Bureau of Standards.”

    Keyhoe goes on to describe the object, noting that “one side of it was flat with odd markings, as if it had been milled. During tests the unknown substance proved to be fire-resistant. But the analysis, Thomas said, had failed to determine whether it was an artificially constructed object or a fragment of some unknown type of meteorite.”

    Keyhoe concluded the brief account by adding that “Afterward the object had been sent to W. B. Smith at Ottawa for further analysis by Project Magnet engineers.”

    One must wonder whether the Condon Committee might have had better success locating the Lieutenant Commander in question if only they had asked the Navy to search for Frank Thomas, rather than Frank Thompson, as Edwards later mistakenly spelled the individual’s name.

    However, further adding to the confusion is the fact that nowhere in the original account written by Keyhoe is it stated that the fragment was dislodged from the UAP during the purported 1952 incident by fire from an aircraft. In Keyhoe’s account, the author only conveys that “a peculiar object had fallen near Washington during the mass saucer sightings in 1952,” though adding that it was “Retrieved by a naval officer.”

    Although Edwards initially only referred to a “military jet” in his retelling of the account in 1966, later in the same chapter he makes passing references to “the fragment collected by gunfire from that Navy jet.” It seems likely that Edwards had merely inferred that a Navy jet had been involved; confusion that may have stemmed from his misreading, again, of Keyhoe’s original account involving a “naval officer” who retrieved the fragment, as well as his primary source, a USN lieutenant commander.

    Based on this, it would appear the insinuation that a Navy jet had been involved was another error made by Edwards, which ultimately the Condon Committee’s investigators relied on without attempting to validate the author’s sources (more on where the idea of a jet’s involvement may have come from will be addressed in the following section). Add to this the fact that they had the wrong name of the alleged lieutenant commander they were looking for, and it becomes quite clear why the Navy was unable to corroborate any of the details in Edwards’ 1966 account.

    THE WILBERT SMITH INTERVIEW

    Although the recent AARO historical report only provides a cursory summary of the alleged 1952 incident based primarily on the Condon Committee’s findings (which, as demonstrated above, were doomed to fail from the outset based on inaccuracies in Frank Edwards’ account), there is still more to this bizarre story of alleged UAP debris. Much of this involves the Canadian engineer and UFO researcher Wilbert Smith, who eventually received the alleged flying saucer fragment according to Keyhoe’s original 1955 narrative.

    A Canadian Department of Transport engineer, Smith ran Project Magnet, a UFO investigative effort that formally ran out of the Canadian government from December 1950 until mid-1954, although Smith’s informal studies involving UFOs continued for many years after the project ended.

    “Smith assessed that UFOs were of extraterrestrial origin and that they flew by magnetism,” the recent AARO historical report states in a summary of Project Magnet that appears in a section addressing Foreign and Academic Investigatory Efforts. “Smith believed he was in personal contact with extraterrestrial beings through telepathy and ‘tensor beams’,” AARO’s investigators add, noting that in a 1961 interview Smith had “claimed that in 1952, the USAF lent him a piece of a UFO to study. He also claimed it was composed of magnesium orthosilicate.”

    A rather revealing transcript of this interview with Smith appeared in Edwards’ 1966 book, based on a recording supplied to the author by Ohio-based researchers C.W. Fitch and George Popovitch, who conducted the 1961 interview. At one point while speaking with Smith, Fitch asked Smith about his association with the retired U.S. Navy Admiral Herbert B. Knowles, to whom Smith had reportedly shown the fragment of the saucer that the U.S. government had loaned him:

    FITCH: You’re a friend of Admiral Knowles, Mr. Smith? [Rear Admiral H. B. Knowles, U.S. Navy, Retired.]

    SMITH: Oh, yes. Admiral Knowles and I have been very good friends for many years.

    FITCH: I have been told by a mutual friend that in 1952 you showed Admiral Knowles a piece of a flying saucer. Is that statement correct, sir?

    SMITH: Yes. It is correct. I visited with Admiral Knowles and I had with me a piece which had been shot from a small flying saucer near Washington in July of that year—1952. I showed it to the Admiral. It was a piece of metal about twice the size of your thumb which had been loaned to me for a very short time by your Air Force.

    FITCH: Is this the only piece you have handled which definitely had been part of a UFO, Mr. Smith?

    SMITH: No. I’ve handled several of these pieces of hardware.

    FITCH: In what way, if any, do they differ from materials with which we are familiar?

    SMITH: As a general thing they differ only in that they are much harder than our materials.

    FITCH: What about this particular piece from that UFO near Washington . . . did it differ from conventional materials? Was there anything unusual about it, sir?

    SMITH: Well, the story behind it is this: The pilot was chasing a glowing disc about two feet in diameter—

    FITCH: Pardon me, sir. But did you say two feet . . . ?

    SMITH: That is correct. I was informed that the disc was glowing and was about two feet in diameter. A glowing chunk flew off and the pilot saw it glowing all the way to the ground. He radioed his report and a ground party hurried to the scene. The thing was still glowing when they found it an hour later. The entire piece weighed about a pound. The segment that was loaned to me was about one third of that. It had been sawed off.

    FITCH: What did the analysis show?

    SMITH: There was iron rust—the thing was in reality a matrix of magnesium orthosilicate. The matrix had great numbers—thousands—of I5-micron spheres scattered through it.

    Fitch then questioned Smith about the whereabouts of the sample the U.S. Air Force had loaned him, to which he responded by providing the following very intriguing remarks:

    FITCH: You say that you had to return it—did you return it to the Air Force, Mr. Smith?

    SMITH: Not the Air Force. Much higher than that.

    FITCH: The Central Intelligence Agency?

    SMITH: [Chuckles] I’m sorry, gentlemen, but I don’t care to go beyond that point. I can say to you that it went to the hands of a highly classified group. You will have to solve that problem—their identity—for yourselves.

    Smith’s insinuations about “a highly classified group” within the United States government that the alleged UFO fragment had been returned to is certainly intriguing, although for more reasons than merely those which are immediately obvious. Another has to do with a memorandum dated November 21, 1950, addressed to the Canadian Controller of Telecommunications, in which Smith discussed inquiries he made at the Canadian Embassy in Washington shortly after acquiring a copy of author Frank Scully’s book Behind the Flying Saucers, an early book on UFOs that recounted a dubious story involving the alleged crash of a flying saucer near Aztec, New Mexico (the incident was later deemed to have been a hoax).

    Smith’s 1950 memo included a series of intriguing remarks that eventually became widely discussed in UFO circles, following the rediscovery of the memorandum in the Canadian National Archives decades later. Specifically, Smith stated that:

    I made discreet enquiries [sic] through the Canadian Embassy staff in Washington who were able to obtain for me the following information:

        1. The [UFO] matter is the most highly classified subject in the United States Government, rating higher even than the H-bomb.
        2. Flying saucers exist.
        3. Their modus operandi is unknown but concentrated effort is being made by a small group headed by Doctor Vannevar Bush.
        4. The entire matter is considered by the United States authorities to be of tremendous significance.

    The entire 1950 memorandum can be read online via the Computer UFO Network here, and a scan of the original 1950 Smith memorandum can be found here via Metabunk, with an additional lengthy thread discussing Smith and his involvement with early UFO research available here.

    The reference to Vannevar Bush in the 1950 memorandum is noteworthy, particularly because Bush’s name would later appear in an infamous series of documents sent to filmmaker Jaime Shandera in 1984, which consisted of briefing papers describing “Operation Majestic 12,” an alleged secret U.S. investigation into UFOs and extraterrestrials that began in the aftermath of the supposed crash said to have occurred at Roswell, New Mexico, in 1947. The Majestic 12 documents, as they have since become known, also later appeared in British researcher Timothy Good’s book Above Top Secret.

    Despite a few intriguing references from over the years like the one in the Smith memorandum, no evidence verifying the existence of “Operation Majestic 12” has ever surfaced. The documents were deemed to be hoaxes in a series of separate investigations, including one conducted by the Federal Bureau of Investigation, which concluded the documents were “completely bogus.”

    It is worth noting that in the recent AARO report’s summary of the Condon Committee’s findings regarding the alleged 1952 saucer fragment affair, the AARO authors state that Frank Edwards “claimed that Dr. Vannevar Bush, a prominent inventor, defense industry scientist, and founder of the National Science Foundation, led the effort to study the fragment.” The citation given for this in the AARO report, number 49, lists “The Condon Report” (Scientific Study of Unidentified Flying Objects) as the source for this, although a search of both the PDF linked to by the AARO report’s authors, as well as an online text version of the Condon Report, reveals no references to Vannevar Bush. This could represent another error on the part of AARO’s investigators, who may have mistakenly attributed Wilbert Smith’s alleged knowledge that a “concentrated effort is being made by a small group headed by Doctor Vannevar Bush,” as stated in the 1950 memorandum, with details in the Condon Committee’s final report.

    THE LETTER FROM REAR ADMIRAL KNOWLES

    There is a final addendum to the story of the 1952 Washington saucer fragment, which involves testimony from the man who was allegedly shown the sample of the object while it was in Smith’s possession. As conveyed earlier in the transcript of C.W. Fitch and George Popovitch’s interview with Wilbert Smith, the latter had confirmed his friendship with U.S. Navy Rear Admiral Herbert B. Knowles, an individual with whom Fitch also corresponded about the alleged 1952 UFO incident.

    In the March 1986 edition of Just Cause, the newsletter of the FOIA activist group Citizens Against UFO Secrecy (CAUS), a letter provided to the editor, Barry Greenwood, from none other than C.W. Fitch lent additional corroboration to the story of the saucer sample Wilbert Smith claimed the U.S. Air Force had loaned him in the 1950s.

    “We must thank long-time UFO investigator C. Wesley Fitch for the following information, which CAUS regards as of great historical interest to our subject,” an entry at the end of the newsletter stated. “Fitch is one of a shrinking group of researchers who knew many of the pioneers of UFOlogy. We regard ourselves as fortunate that he chose to give this impressive little tid-bit to us.”

    The item in question had been a series of then-25-year-old correspondences shared with CAUS, revealing “that former Navy Rear Admiral Herbert B. Knowles was involved in the examination of fragments of a UFO shot at over Washington, D.C. in 1952.” As it turned out, in addition to recording the interview where Wilbert Smith acknowledged his friendship with Admiral Knowles, Fitch had also corresponded with Knowles about the saucer fragment Smith claimed to have shown him while on loan from the United States.

    As explained in the CAUS newsletter, Fitch, a member of the National Investigations Committee on Aerial Phenomena (NICAP) had been told by one of the organization’s board members, the Reverend Albert Baller, about a visit he received from Admiral Knowles (also a board member of NICAP at the time) during which the two men discussed UFOs. Throughout their discussion at Baller’s home, Knowles recounted how he was allowed to examine the purported UFO fragment in Smith’s possession, which he said had been shot off a small glowing disk in 1952.

    Fitch managed to track down Admiral Knowles, who at the time (1961) had been living in Eliot, Maine, and wrote to him asking for confirmation as to whether he had indeed examined the alleged saucer fragment. In a response dated August 27, 1961, Knowles wrote back to Fitch, divulging the following intriguing account of his recollections about the visit with Smith:

    Yes, I have had a piece of a small disc in my hands. It was shown me by Mr. Wilbert Smith (address given- Ed.). At that time (1952), Mr. Smith was heading the “Flying Saucer” research of the Canadian government and working in very close cooperation with our authorities in Washington, D.C. He is still very much interested in this matter and does independent research. The Canadian Govt. has “officially” abandoned the project.

    To the best of my recollection the object was shot down by a plane and seen to fall in the yard of a farmer across the river in Virginia. Upon searching the area several pieces were found, one of which was turned over to Mr . Smith for independent research. In one of his trips down to see me he brought the piece along for my inspection.

    It was a chunk of amorphous metal-like structure, brownish in color where broken, with a curved edge indicating the whole thing to have been not over 2′ in diam. The edge was rounded in cross section, perhaps a quarter inch thick and obviously swelled to a considerably greater thickness at the center. The outer surface was smooth but not polished, and at the broken sections there were obviously iron particles and even evidence of iron rust. I would say that the weight was somewhat lighter than if of solid iron, but it was not extremely light.

    Mr. Smith told me that a chemical test had been made of the piece at hand, that iron had been found in it but little if anything else could be identified.

    Concluding his account, the retired Admiral then asserted his belief that the fragment he examined had belonged to a “remotely-controlled observation disc,” the likes of which have been “seen many times, most often in the vicinity of defense installations.”

    A follow-up letter from Knowles, dated October 11, 1961, included a sketch of the alleged UFO fragment, a version of which was redrawn and included in the CAUS newsletter based on faded originals provided to Fitch (see below).

    Update: Another interesting piece of this puzzle was brought to our attention by historical researcher Jeff Knox, involving samples purportedly collected in Virginia by Commander Alvin E. Moore in 1952. Like the original account by Donald Keyhoe from 1955, Moore also claimed his sample was analyzed by the Bureau of Standards, referring to it and others in his possession as “stones,” along with associated “materials” that he believed to have been related to UFOs.

    In a letter to Condon Committee project coordinator Robert Low dated January 5, 1968, Moore offered to produce a report based on his investigations into UFOs and the materials in his possession. Following a brief response sent to Moore, Low subsequently wrote to Dr. J. Thomas Ratchford at AFOSR Headquarters, expressing doubts about the relevance of Moore’s samples, although noting that there was “a good deal that is strange about Moore’s experience.” Specifically, a UFO report Moore said he sent to Wright-Patterson AFB could not be located by Project Blue Book staff, according to Low, who added that an analysis of the “artifact” Moore found in 1952, “which he says was done by the National Bureau of Standards, was never written down.” Intriguingly, Low then speculated to Ratchford about the possibility that Captain Edward J. Ruppelt, the first director of Project Blue Book, could have “made off with some of the files of sightings,” though conceding that Moore’s sighting report might simply have been lost, or may never have been sent to Blue Book. For further details on this, copies of the exchanges between Moore and Low, as well as Low’s letter to Ratchford, can be read here.

    CONCLUSIONS

    As a deeper analysis into this alleged 1952 incident has revealed, the DoD’s recent investigations into the matter amounted to little more than a rehashing of the flawed conclusions of the Condon Committee from decades ago, whose investigators, as we have now seen, relied on incorrect data provided in a popular book on UFOs from the 1960s as the basis for their investigations.

    Thus, to briefly summarize:

    1. AARO’s recent historical report features a short entry on the University of Colorado UFO Project (i.e., the Condon Committee) and its findings, including its investigation into claims made in a 1966 book by Frank Edwards involving a fragment allegedly shot off a UFO by a U.S. Navy aircraft near Washington, D.C., in 1952.

    2. While the Condon Committee determined the incident had likely never occurred, the information used as the basis for its investigations had been incorrect details from Edwards’ book, resulting from his probable misreading of information in an earlier 1955 book by author Donald Keyhoe. The Condon Committee’s investigators seemingly did not scrutinize this information before providing it to the U.S. Navy, which, understandably, was unable to verify the erroneous claims.

    3. AARO’s report attributes unverified claims involving American defense industry scientist Dr. Vannevar Bush to statements from Frank Edwards in 1966, although his book published that year makes no references to Bush, nor does the Condon Committee’s final report, which AARO cites as its source for this assertion in its recent report. It seems likely that a possible origin for the claims involving Bush may have been a 1950 memorandum attributed to Wilbert Smith, who was allegedly loaned a portion of the UFO fragment by the U.S. Air Force two years later.

    4. A recording of a 1961 interview the Ohio-based researcher C.W. Fitch conducted with Smith, partially transcribed in Edwards’ 1966 book, details Smith’s recollections about the purported UFO fragment he was loaned and insinuated that it was returned to a “highly classified group” within the United States government. Additional correspondences between Fitch and Rear Admiral Herbert B. Knowles from 1961, and later supplied to the activist organization CAUS, confirmed that Knowles had been shown the object during a meeting with Smith in 1952, corroborating Smith’s claims of having once had the fragment in his possession. A possible origin for the sample Smith reportedly borrowed and studied had been Commander Alvin Moore, who later approached the Condon Committee about potentially collaborating with the project.

    If the AARO report had indeed conducted an “exhaustive analysis” of U.S. government records associated with UAP, one would expect they would have also easily spotted errors in the publicly accessible resources like the Condon Committee report, as well as Frank Edwards’ 1966 account involving the alleged UFO fragment from 1952.

    Instead, as indicated by AARO’s contention that “it is not clear” whether the alleged 1952 incident had been associated with claims that the Canadian government was loaned a sample from a UFO, it is hard to see past the fact that the AARO’s investigators performed little more than a cursory examination of the 1952 UFO case… just like the Condon Committee had done decades ago. Thus, one wonders: what else might they have overlooked?

    This all may seem inconsequential to some, especially since the present analysis alone cannot “prove” that a fragment was indeed blasted off a small, drone-like UFO near Washington in 1952. However, what this analysis does help to illustrate, taken alongside the numerous other factual errors within AARO’s recent report, is that questions regarding the merit of AARO’s broader historical investigations are indeed warranted. It is also not impossible that, if such problems as those addressed here were taken into further consideration by AARO in advance of the publication of Volume II of its historical report, perhaps they may be better equipped to satisfactorily resolve some of these lingering questions.

    Altogether, maybe these decades-old claims about a fragment shot off of a flying saucer, which past studies (and more recent ones) have claimed “were most likely false,” should warrant further attention after all.

    And if nothing else, perhaps, given such considerations, we can better understand why many Americans remain skeptical about their government’s latest proclamations regarding the long-reviled subject of UFOs.
