Pillar UFO Over Japan Volcano Live Cam, Feb 27, 2022, UFO Sighting News.
I was hunting UFOs using live cams. This is an essential tool that allows a researcher to watch worldwide at any given moment. Sadly live cams are under used by researchers. Here I found two craft that are cylydrme shaped. One stands out well above the mouth of the volcano. The other is less obvious...its in front of the volcano and lower. This object is huge, about the size of a 747 standing on end! Clouds are seen passing over the UFO...this is 100% proof that it is real. At times the UFO disappears behind the clouds, other times its in front of them. Absolute amazing and brings back memories of a movie called Arivals. Wow! Just wow!
In every war there are often lesser known experiences floating about beyond the typical tales of fighting and heroism. Here in the background of all of the conflict and death often lurk outlandish accounts of something strange going on, something perhaps even more frightening than the enemy. The Vietnam War, also known as the Second Indochina War, fought between the years of 1955 and 1975, officially between North Vietnam and South Vietnam, but as most know America being pulled into it starting from 1964, also has such otherworldly tales. One aspect of the Vietnam War that has long slipped under the radar of the mainstream consciousness is that amongst the fighting and violence the conflict was absolutely rife with reports of strange things in the sky that defied conventional explanation. Reading like something out of a science fiction story or alien invasion flick, these frightening accounts of encounters with UFOs during the Vietnam War suggest that it was not only the North Vietnamese forces that were the spookiest things out there, but also decidedly more otherworldly forces as well.
By all accounts it seems that troops in the Vietnam War were absolutely plagued by UFO activity, and some of the most spectacular reports of alien encounters during the Vietnam War have to do with actual military engagements with UFOs. One such incident allegedly occurred on June 15, 1968, along the demilitarized zone (DMZ) between North and South Vietnam, where a patrol boat known as PCF-12, commanded by a Lieutenant Pete Snyder, was on a routine night patrol near Cua Viet. At 12:30AM, PCF-12 reportedly received a frantic distress call from another patrol boat in the vicinity, PCF-19, claiming that they were being attacked by unidentified lights they were calling “enemy helicopters,” which seemed odd because the North Vietnamese enemy were not known to utilize combat helicopters at the time.
Snyder ordered the PCF-12 to head for PCF-19’s position to offer assistance, and they as they closed in reported spotting in the sky two circular bright lights immersed in a “strange glow” hovering over PCF-19’s position. As they approached, one of the strange lights reportedly emitted a bright flash of light, after which PCF-19 exploded in a cascade of water and flying debris. Directly after the destruction of PCF-19, the two enigmatic lights were described as rapidly accelerating away towards the sea as PCF-12 scouted the area for any possible survivors of the carnage they had just witnessed. Two wounded men were found and recalled that the two UFOs had been trailing them for miles along the river. The survivors then claimed that they had decided to fire upon the threatening, mysterious objects, and that was when one of them had issued a piercing blast of light to obliterate the boat. At first it was thought by officials that the PCF-12 had been the victim of an enemy missile fired from shore, but a later AP dispatch from Saigon would quote a military spokesman as having attributed the loss of PCF-19 to an “unidentified object,” and not enemy coastal batteries or missiles.
The PCF-12 continued its patrol up the river and were soon approached by the same two unidentified lights, which took up positions hovering on the port and starboard sides around 300 yards away and 100 feet above the water. PCF-12 called in to headquarters to try and get an idea of what they were dealing with, but were met with the response that there were no aircraft in the area at the time. Realizing that these craft were not friendly, Snyder ordered his men to open fire on the lights, which apparently did little to faze or even slow them down, and PCF-12 began to retreat at full speed as the two mysterious aircraft tailed and stalked them, flickering in the night the whole time. Second engine man Jim Steffes would later claim that he got a good look at the craft and described them as having “a rounded front like an observation helo,” and what looked like “two crewman sitting side by side.”
Strangely, although no weapons could be seen mounted on the unidentified aircraft, PCF-12 nevertheless found itself being fired upon. Steffes remembered seeing tracer rounds piercing up into the night from the nearby base Point Dume, with their targets being what he said were other far-off blinking circular lights whizzing about in the sky above. Eventually, a group of Phantom F4 fighter jets arrived to converge upon and chase off the strange lights that were plaguing PCF-12 out to sea, leaving the crew to wonder what in the hell had just happened.
At roughly the same time, another very strange incident was unfolding out in the South China Sea with an Allied ship of the Royal Australian Navy, the HMAS Hobart, which was patrolling near Tiger Island, about 20kms off Cap Lay and reported sighting up to 30 unidentified slow-moving lights hovering in the night sky near their ship, which were at first thought to be Russian-built M-14 ‘Hound’ helicopters, but upon closer inspection it could be seen that they were not. US 7th Air Force Phantom fighter-bombers were sent to engage, supported by generous anti-aircraft fire from the ground. The lights flew out to sea as they were pursued by the fighters, which fired upon them mercilessly along with several other military ships in the area, which unfortunately contributed to the friendly fire incident in which a U.S. swift boat was sunk by missiles, killing 5 of the 7 crew.
The HMAS Hobart was prepped for battle when the radar room detected an incoming unidentified aircraft coming in fast with no identification number to mark it as friend or foe. Word soon came in that the craft was “friendly,” but it was then that a missile struck the ship to kill one and injure two others, followed by a barrage of two more missiles. Whatever the craft was swiftly fled the scene before it could be shot down. In the meantime, F4 jets scrambled about firing upon the lights, joined by a hail of anti-aircraft fire from the ground, with attempts to communicate with whoever was onboard the mystery craft going unanswered. Eventually, the lights floated off and the fighter pilots were ordered back to base. The following morning, a complete search of the area turned up not a single shred of wreckage of an enemy helicopter, or any other enemy aircraft for that matter, despite the intense fighting that had occurred. The complete and utter lack of any wreckage of any aircraft was baffling considering that these enemies had come under such resistance and been met with so much concerted, relentless fire. The Royal Australian Navy News would later confirm:
No physical evidence of helicopters destroyed has been discovered in the area of activity nor has extensive reconnaissance produced any evidence of enemy helicopter operations in or near the DMZ.
There was little confidence among the men engaged in the incident that the aggressors had been “enemy helicopters” as was at first claimed. After all, if that were the case they should have been decimated by the potent retaliatory force displayed upon their arrival and attacks. There was also no trace whatsoever of helicopters at the time in the area before or during the incident and no wreckage afterwards. A skipper aboard the Hobart during the baffling engagement would later claim that it was certainly not enemy helicopters, expressing his doubt of such a theory by saying:
Neither before nor after the incident … was there any report by any of the ships of a helicopter being there [around Tiger Island]. Now having said that, the captain of one of the American ships told me later at Subic Bay that he thought there were helicopters there, but the fact is he didn’t report, and if he believed there was a helicopter … it was his duty to report it at the time, but there was no report.
Whatever the lights were that caused so much chaos continued to be sighted sporadically for months afterwards along the DMZ, furtively skirting around the area, wandering back and forth over the line, and baffling those who saw them. They were often sighted by radar roaming up and down the coast, and apparently no one could quite figure out what they were. They appeared on radar to be low, slow moving objects just like helicopters, but often there would be no visible confirmation or they would not look at all like helicopters. They were also prone to just disappearing into thin air, and jets scrambled to intercept the objects would arrive to find nothing there. Troops on the ground would sometimes witness the lights appear and disappear out of nowhere, and in one such case American artillerymen reported seeing a group of mysterious lights along the Ben Hai River, but when they had opened fire on them the objects had suddenly vanished as if they had never been there at all. At no point did anyone report seeing an actual helicopter, and the strange objects were always described as moving lights, often hovering erratically or moving in sudden bursts of speed inconsistent with a helicopter.
The origin of the strange lights remains unknown to this day. There were theories at the time that somehow a misreading of radar signals had occurred, which had then made other friendly vessels appear to be slow moving flying blips, or that the North Vietnamese had more helicopter power than had been previously assumed. In the end the official explanation was that it was all due to atmospheric disturbances or possible enemy helicopter activity, coupled with panicked friendly fire, and there have also been theories that it was all due to bird flocks or even insect swarms, but does any of this really match up to what occurred? Would trained Navy and fighter jet personnel go to engage such mundane phenomena? What hit the Hobart? Indeed what attacked the PCF 12 and 19 at precisely the same time? If there were enemy helicopters involved where was all the wreckage, why were they never successfully shot down, and wouldn’t these trained men know helicopters when they saw them? It is also strange that an enemy helicopter would so brazenly venture over the heavily defended DMZ, and it would be strange that they should fly around with their lights on all of the time for hours on end. In the case of the Hobart it seems obvious that this was some sort of concerted attack, but by who or what remains open to debate and speculation.
It is interesting that these reports make mention of “enemy helicopters,” as this was a term used so often to describe any unidentified lights in the sky in Vietnam that it became sort of a code word for “UFO,” regardless of any relation the object had to an actual helicopter, becoming sort of a catch-all phrase for anything weird in the sky. The fact that the Viet Cong were not known to use helicopters made it a perfect way to explain discreetly when men were seeing something in the sky that shouldn’t be there. On October 16, 1973, the USAF Chief of Staff, General George S. Brown, gave a press conference in Illinois where he addressed this terminology to some extent when asked about UFOs in Vietnam, saying:
I don’t know whether this story has ever been told or not. They weren’t called UFOs. They were called enemy helicopters. And they were only seen at night and they were only seen in certain places. They were seen up around the DMZ [demilitarized zone] in the early summer of ’68. And this resulted in quite a little battle. And in the course of this, an Australian destroyer took a hit and we never found any enemy, we only found ourselves when this had all been sorted out. And this caused some shooting there, and there was no enemy at all involved but we always reacted. Always after dark.
Another comment on the matter was made by a patrol boat captain by the name of Bill Cooper, who served in Vietnam from 1967 to 1969. During a UFO conference in Los Angeles in 1989, Cooper would say of his own experiences:
After about five months I was sent up north to the DMZ, to a place called Qua Vieaf [perhaps Qua Viet] on the Tacan [sic] river …. It was while there that I discovered that there was a tremendous amount of UFO and alien activity in Vietnam. It was always reported in official messages as ‘enemy helicopters’. Now any of you who know anything about the Vietnam war know that the North Vietnamese did not have any helicopters especially after our first couple of air raids into North Vietnam [during 1965]. Even if they had, they would not have been so foolish as to bring them over the DMZ, because that would have ensured their demise.
Another American ship was not directly attacked, but nevertheless allegedly had a very intimidating and threatening encounter with an Unidentified Underwater Submersible, or USO. In 1974 the ammunitions ship the USS Kilauea was operating in the Indian Ocean along with a destroyer and a carrier, and the witness claims that one evening at around 9PM he had been on deck with two friends looking up at the brilliant array of stars in the night sky. Their attention was drawn to the eerie beauty of the shifting light trails formed by phosphorus algae in the wake of the ship in formation in front of them, yet as they watched this light display of nature something else began glowing in the depths, becoming brighter and brighter until it became a blinding orange/yellow ball just under the surface. The mysterious blazing orb then spectacularly burst forth from the water to arch right over the top of the destroyer, just missing smashing into it, before crashing back into the ocean on the other side and sinking back into the dark depths. The witness would say of the puzzling, frightening incident:
We all just stared at each other with our mouths open. We could not believe what we saw, but I asked friends of mine who were on watch on the bridge if they saw it and they all did. There was nothing ever reported that I know of though and we just quit talking about it. I bet the destroyer got a good look at it. It went right over the bridge of that ship and it was big. Maybe 150 to 200 feet in diameter. That was my big encounter.
It is all a very intriguing peek into some of the more mysterious aspects of this conflict. Such tales lurk beyond the known history of the Vietnam War, hiding in the cracks and shadows and invisible, lost to the mists of time save for the few who are willing to share their bizarre tales. What went on out there in the skies above all of the fighting? What were these troopers dealing with? Were these cases some sort of experimental aircraft, the stresses of combat playing tricks on the imagination, or something altogether more bizarre? The true answers have been buried by history and lost to the mists of time.
I often hear people say that the UFO phenomenon is a strong one and that “they” are here to help us. Well, that might be the case. On the other side of the coin, however, a case can be made that the mystery isn’t as quite as friendly as so many might think it is. In fact, the visitors might actually be weak entities that fear us – but who have found intriguing ways to make themselves appear way ahead of us. For example, consider the number of UFO encounters that have occurred over military bases. There are more than a few cases of this particular type. And, that’s what I’m going to share with you today. We know for sure that the Summer of 1947, in the United States, was swamped with reports, sightings and encounters – and many of them involving military installations. For example, during that same 1947 wave (in New Mexico), there were a number of significant sightings of UFOs at what used to be called the White Sands Proving Ground (and that, today, is titled the White Sands Missile Range). What if the real truth of these events was something much stranger? Consider this: just because the “visitors” may have had technology way ahead of ours in 1947 (and now, too), it doesn’t mean they had a huge armada of craft. Perhaps, it was the exact opposite: that they had a limited number of ships, but carefully managed to make it look like they were all over the place by placing one incident here, one there, and so on.

Perhaps, the various – and famous – cases of UFO sightings in the direct vicinity of military and government facilities over the decades have been nothing but staged events designed to show their power, when, in reality, they might be quite vulnerable when it comes to numbers and power. Let’s look at some other examples of UFO “invasion” with military connections. The curious and fantastic UFO events of July 1952, over Washington, D.C., deeply troubled the CIA and the Air Force. And, for very intriguing and alternative reasons that had very little to do with literal alien invasions or visitations. On December 2, 1952 the CIA’s Assistant Director H. Marshall Chadwell noted in a classified report on UFO activity in American airspace: “Sightings of unexplained objects at great altitudes and traveling at high speeds in the vicinity of major U.S. defense installations [italics mine]are of such nature that they are not attributable to natural phenomena or known types of aerial vehicles.”
A similar wave hit the U.K. in 1957. On March 26 of that year, there was an amazing encounter. The U.K. Air Ministry documentation (now in the public domain at the National Archives) states in part: “A report was received from Royal Air Force Church Lawford on 26th March, 1957 of a sighting of an unusual nature. The object moved at a speed timed at exceeding 1400mph. This in itself was unusual as the object had accelerated to this speed from a stationary position [italics mine]. No explanation has yet been found for this sighting but a supplementary report, including a copy of the radar plot, was requested and has been received from Church Lawford this afternoon.” The craft came perilously close to the base and was described as a Flying Saucer. On the morning of April 4, 1957 – according to now-declassified British Royal Air Force documents housed at the National Archives, Kew, England – radar operators at Balscalloch, Scotland reported to RAF West Freugh, Wigtownshire that they had detected a number of “unidentified objects on the screens of their radars.” And it quickly became apparent this was no Cold War penetration of British airspace by Soviet spy-planes or bombers. As the mystified radar-operators watched their screens, they were amazed to see a large, stationary object hovering at 50,000 feet that then proceeded to ascend vertically to no less than 70,000 feet. The U.K. was also hit with a similar UFO wave in 1967.
Moving on, there is the UFO deluge that occurred in the United States from 1973 to 1974. At the time of the encounters, the U.S. Department of Defense (DoD) took a significant interest in them. The most interesting file is titled “Spanish UFO Sightings.” It surfaced, in the 1980s, from the archives of the U.S. Defense Intelligence Agency (DIA). It’s a collection of data that the DoD secured specifically from Spanish newspapers and that provides a notable and useful look at that large wave of activity. In part, the DoD said: “During the period September 1973 to June 1974 a rash of UFOs appeared over Spain and sightings were reported by various types of people. The following table summarizes these sightings. Date: 11 Sep 73. Location: El Ferrol del Caudillo. Description: Bright, circular, with two hoops, appeared to have feet on bottom part. Emitted a very powerful light. Observer: Various. Remarks: Was immobile during time of observation. Date: 11 Dec 73 (early morning). Location: Malaga. Description: Circular, like a flying saucer, had an intense red light. Observer: Various residents of Salitro and Cuarteles Streets, Malaga. Remarks: Remained quiet for about 15 minutes, then departed suddenly towards Torremolinos.” And, one year later – in 1975 – there was a strange wave of mysterious helicopters seen near U.S. bases – a matter that was never fully resolved. Some might say that the Rendlesham Forest incident of December 1980 was such an example, too: a theoretical, careful ruse to make aliens look powerful in the midst of trained military personnel. Extremely notable, too, is the 1989/1990 sightings of “Black Flying Triangles” that got the Belgium military in states of confusion and concern.
In all of these cases we can theorize that whoever was behind them, they deliberately put on spectacular shows for us. They wanted to be seen. They wanted to demonstrate a power they might not actually have had. But, for our wide eyes, and by flying over top secret installations, it did look like they were all-powerful. And, surely, there must have been a high degree of dicey gambling on their part. The alien phenomenon – if that is really what it was/still is – may not be what it appears to be. Our strange visitors might be doing their best to make it look as if we are here, there and everywhere and are armed with technology way ahead of us. And, by successfully manifesting around sensitive sites time and again, our world leaders probably believe the invaders are the stronger ones. But, in reality, we might have the upper hand – if only we knew it.
Curiosity Finds a Bizarre Rock on Mars that Looks Like a Flower
Curiosity Finds a Bizarre Rock on Mars that Looks Like a Flower
The Curiosity rover took a picture of something pretty enticing this week on the surface of Mars. While the object in question looks like a tiny little flower or maybe even some type of organic feature, the rover team confirmed this object is a mineral formation, with delicate structures that formed by mineral precipitating from water.
Curiosity has actually seen these types of features before, which are called diagenetic crystal clusters. Diagenetic means the recombination or rearrangement of minerals, and these features consist of three-dimensional crystal clusters, likely made of a combination of minerals. Curiosity deputy project scientist Abigail Fraeman said on Twitter that these features that were seen previously were made of salts called sulfates.
From studies of previous features like this found on Mars (you can read a paper on them here), originally the feature was embedded within a rock, which eroded away over time. These mineral clusters, however, appear to be resistant to erosion.
Another name for these features is concretion, which you may remember from the Opportunity rover, who saw features that were nicknamed ‘blueberries,’ since they were small and round. You can see round concretions next to the flower-like feature in this image.
The rover science team saw this feature earlier this week and named it ‘Blackthorn Salt’. They used the rover’s Mars Hand Lens Imager, called MAHLI, to take these close-up images. This camera is the rover’s version of the magnifying hand lens that geologists usually carry with them into the field. MAHLI’s close-up images reveal the minerals and textures in rock surfaces.7
Here you can see a 3-D model of the object, thanks to Simeon Schmauss:
Curiosity found another flower-like feature back in 2013, and the Spirit rover found similar-looking rocks that were nicknamed ‘cauliflower’ features because of their knobby protuberances.

In Australia first creator of men is Biame, he has other names like thoth, thats what the Egyptians named him as all people had different words for him in different tribes, mean same thing. He gave Natives Australians lore, written on standing stones that were destroyed by a farmer threatened by the government in the 1900s. Lucky they were recorded, get the book, forgotton origins.
Then the second son of blame is called the nameless one, he died because land dried up and he didnt want to eat meat and died, he is now the southern cross, our brother. Ea didnt make the southern cross, as you have mentioned, our first brother to die became stars. This is the first stars in the sky, before that, no stars at all. Very old old old old old true story.

Fireball Lights Up Colorado Sky; But Astronomers Reveal the Meteor Was Moving Surprisingly Slow
When a meteoroid crashes through the Earth's atmosphere, it heats up due to friction from the air, creates a streak of light in the sky, and becomes a meteor. People often refer to meteors as fireballs, shooting stars, or falling stars because of the bright light they create. National Geographic said that even the smallest meteors could be visible from miles away because of their brightness and how fast they travel.
The fastest meteor they recorded traveled at 44 miles (71 kilometers) per second. The faster and larger a meteor is, the brighter it glows. But the meteor that lit up Colorado's night sky last Friday, February 18, seemed to deviate from the typical speed of a meteor based on the analysis conducted by astronomers.

Fireball Lights Up Colorado Sky; But Astronomers Reveal the Meteor Was Moving Surprisingly Slow
Atypical Speed for A Meteor
Last Friday night, the American Meteor Society was flooded with 30 reports of a bright and long-lasting fireball across the Colorado sky at around 8:30 PM.
UPI reported that astronomers had analyzed the speed at which the meteor streaked across the night sky and discovered it had an unusually long path and was moving at a slower rate than a meteor would typically travel. Fiske Planetarium director John Keller said that the meteor that sparked the dozens of reports was a bolide or a large meteorite.
Astronomer Chris Peterson from the Cloudbait Observatory also told local news outlet CBS Denver that the instruments that tracked the meteor's path seen in Colorado started to follow it from Steamboat, Colo to the border of New Mexico. He added that it was unusually slow and had an atypical long path.
Peterson gave two possible explanations: the meteor might have bounced off the atmosphere and headed back to space, or the meteor may have burned up completely. The space rock is estimated to have traveled about 60,000 miles per hour, which is considered unusually slow for a fireball. He believes that none of the meteor's fragments could have landed on Earth.
According to National Geographic, meteors can be categorized based on their size, brightness, and proximity to Earth. Meteors are earthgrazers that bounce off the upper atmosphere and re-enters the space, while some break up and streak through the sky in bright light.
The most famous earthgrazer "1972 Great Daylight Fireball," entered Earth's atmosphere and streaked through the sky of Utah and traveled at 9 miles per second (15 kilometers per second). The meteor exited the atmosphere over Alberta, Canada, witnessed by thousands of people.
One of the types of meteors is the fireballs, which could range in size from a basketball to a small car and are probably the most common type. Some experts claim that fireballs are bright and longer-lasting than any planet.
Meanwhile, a bolide is even brighter and more massive and often explodes in the atmosphere, where sounds can be heard and felt on Earth's surface. Some of them are classified as fireballs that produce a sonic boom as they streak through the sky.
Lastly, a superbolide is brighter than a bolide and creates a large explosion that can become a natural hazard and pose a danger to people. In 2013, a superbolide passed over Chelyabinsk, Russia, wherein the explosion could be compared to 500 kilotons of TNT.
Meteorite older than Earth likely came from a “protoplanet”
Meteorite older than Earth likely came from a “protoplanet”
The rock, found in the Sahara, likely comes from a long-lost baby protoplanet.
Erg Chech 002 is a meteor not like any other ever found.
It’s older than the Earth, and its composition raises interesting possibilities.
The meteor likely comes from an early baby planet in our solar system.
Scientists are discovering all sorts of amazing told by the meteorites found scattered across the Earth’s surface. Now a team led by Jean-Alix Barrat, a geochemist from the University of Western Brittany in France, have announced in a study that one such rock is apparently incredibly ancient, predating the Earth altogether. They believe it comes from a long-gone protoplanet, a baby planet that never got the chance to grow up, so to speak.
Its name is EC 002, and it may provide new insights into the early days of our solar system.
Erg Chech 002, or EC 002, was found in Adrar, Algeria last May in the nearly uninhabited Erg Chech region of the Sahara Desert. It was one of several chunks of meteorite discovered — together they weighed 32 kilograms (about 70 lbs). The Lunar and Planetary Institute describes EC 002 as being “relatively coarse grained, tan and beige appearance with sporadic larger green, yellow-green and less commonly yellow-brown crystals.”
A rough identification of EC002 classified it as an achondrite, which immediately differentiated it from most meteorites, which are chondritic.
Chondritesare pre-planetary stony rocky formed billions of years ago from dust and mineral grains of the early solar system.
Achondritesare rocks blasted off the face of planetary bodies, so they are newer. Their composition can provide clues to the formative processes of their sources since they they exhibit characteristics consistent with the period of internal melting that separates the core from the crust of a young planet. They’re also relatively uncommon. Of the tens of thousands of meteorites listed in the Meteroitical Bulletin Database, just 3,179 of them are achondrites.
Most of the meteorites found, about 95 percent, come from just two bodies out there in space, and about 75 percent may come from a single, large asteroid called 4 Vesta.
Here’s where we go from unusual to very unusual. Achondrites are usually basaltic, originating in a planetary body’s basaltic crust. EC 002 is not. It’s volcanic, a type of rock called andesite. The scientists have measured the radioactive isotopes of aluminum and magnesium it contains and concluded the minerals crystallized about 4.566 billion years back. Earth, by contrast, dates back only 4.54 billion years.
This chunk of cooled magma is a lonely survivor of that long-ago past. The authors write that “no asteroid shares the spectral features of EC 002, indicating that almost all of these bodies have disappeared, either because they went on to form the building blocks of larger bodies or planets or were simply destroyed.”
The andesite in EC 002 is interesting. On Earth, andesite’s sodium-rich-silicates are found in subduction zones where one tectonic plate sinks under another. (The basalt-like material in most chondrites forms when magnesium- and iron-rich lava cools.)
Still, EC 002 isn’t the first andesite meteor found, and a study of two of them (Graves Nunataks 06128 and 06129) discovered in Antarctica raises the possibility that they form from the melting of planetary bodies comprised of chondrites.
Some have theorized that if this is so, and since chondrites are so common, it could be that their melting into an andesite crust was a common occurrence during planetary formation. Indeed, Barratt’s study says, “It is reasonable to assume that many similar chondritic bodies accreted at the same time and were capped by the same type of primordial crust.”
It’s an interesting notion, albeit with two problems.
First, the light-reactive properties of EC 002 aren’t like anything else in the universe among the 10,000 objects in the Sloan Digital Sky Survey database.
Second, not that many andesite meteors have been found, making one wonder where they all might’ve gotten to. They might have gotten smashed up and broken apart. Or maybe they were subsumed in the formation of later planets. Like our Earth.
Venus’ clouds may harbor ‘aerial’ aliens, MIT scientists say
Venus’ clouds may harbor ‘aerial’ aliens, MIT scientists say
Scientists have detected within the Venusian atmosphere a chemical known to be a byproduct of life.
KEY TAKEAWAYS
A team of researchers has detected significant amounts of phosphine within the cloud deck of Venus.
Computer simulations suggest that the amount of phosphine in the Venusian atmosphere couldn't have been produced by known inorganic processes.
The findings aren't conclusive evidence of alien life, but they do suggest Venus shouldn't be overlooked in the search for alien life.
The skies of Venus may contain signatures of alien life, according to scientists at the Massachusetts Institute of Technology.
In the search for alien life, the second planet from our Sun has long been ignored. It’s easy to see why: the Venusian surface reaches temperatures exceeding 800 degrees Fahrenheit; its dense atmosphere applies nearly 100 times more pressure to objects than Earth’s atmosphere; and the planet rains sulfuric acid, a corrosive chemical that causes severe burns to humans.
As such, most scientists have focused on finding signs of ancient alien life on Mars, or current life on moons like Europa or Enceladus. But Earth’s closest neighbor might have been the place to look all along.
A new paper published in Nature Astronomy shows that the Venusian atmosphere seems to contain significant amounts of phosphine, a chemical that’s known to be a byproduct of life.

It’s not conclusive evidence of life: Phosphine (PH3) can be produced through inorganic processes, like interactions involving sunlight, surface minerals, volcanic activity, and lightning.
But the study authors considered these and other potential sources, and they created computer models to test whether they could simulate the production of phosphine on Venus. The results produced small amounts of the chemical, but not nearly as much as multiple observatories have detected within the cloud decks of Venus.
So, for now, scientists don’t know what’s producing the phosphine. Alien life remains a plausible explanation.
“Technically, biomolecules have been found in Venus’ atmosphere before, but these molecules are also associated with a thousand things other than life,” study co-author Clara Sousa-Silva told MIT News. “The reason phosphine is special is, without life it is very difficult to make phosphine on rocky planets. Earth has been the only terrestrial planet where we have found phosphine, because there is life here. Until now.”
If life really is producing the chemical, it’s likely anaerobic life, which are organisms that don’t require oxygen. Interestingly, such lifeforms would probably be “aerial” aliens, floating within a relatively thin slice of habitable atmosphere, surrounded by otherwise hellish conditions.
How would those lifeforms have gotten there? Sousa-Silva explained:
“A long time ago, Venus is thought to have oceans, and was probably habitable like Earth,” Sousa-Silva told MIT News. “As Venus became less hospitable, life would have had to adapt, and they could now be in this narrow envelope of the atmosphere where they can still survive. This could show that even a planet at the edge of the habitable zone could have an atmosphere with a local aerial habitable envelope.”

The researchers emphasized that the detection of phosphine in the Venusian atmosphere isn’t necessarily evidence of life, but rather of “anomalous and unexplained chemistry.” Still, they hope to confirm their findings with additional observations, including a potential probe mission, which would be NASA’s first since Pioneer Venus 2 entered the Venusian atmosphere in 1978.
Theoretical inventions known as the “UFO patents” have been inflaming worldwide curiosity. A product of the American engineer Dr. Salvatore Cezar Pais, the patents were filed during his work for the U.S. Navy and are so ambitious in their scope and imagination that they continue to draw interest despite any clear evidence that they are feasible. The patents include designs for a futuristic hybrid vehicle with a radical propulsion system that would work equally well in the air, underwater, and in space, as well as a compact fusion reactor, a gravitational wave generator, and even a “spacetime modification weapon”. The technology involved could impact reality itself, claims its inventor, whose maverick audacity rivals that of Nikola Tesla.
The patents
How real are these ideas? While you can read the patents for yourself, it's evident that the tech necessary to actually create the devices described is beyond our current capabilities. Yet research into many of these fields has gone on for years, which may explain why the Navy expressed an interest. Another likely influence is the fact that the Chinese government seems to be working to develop similar technology.
One of the most attention-grabbing designs by Dr. Pais is the2018 patent for a cone-shaped craft of unprecedented range and speed. The amazing vehicle would be able to zoom around with ease both high in the air and deep in the sea. It would travel through air, water, and space by generating a quantum vacuum with an energy field. This vacuum around its body would help it push away any molecules it encounters, regardless of the medium. The craft would also not leave any heat signature, making it virtually undetectable. Controlling the “quantum field fluctuations” in the vacuum would counteract inertia and resistance, resulting in “extreme speeds.” Reducing a craft’s inertial and gravitational mass in this way could be transformational for space travel. It sounds like an enticing design. However, as noted, it’s not something we could actually create with current technologies.
Another futuristic patent with far-reaching ramifications is Pais’ Plasma Compression Fusion Device. It would be relatively small, less than two meters in length, and house fusion reactions generating power in the gigawatt (one billion watts) to terawatt (one trillion watts) range. By comparison, a coal plant or a nuclear reactor generate energy in the one to two-gigawatt range.
Notes from researchers who worked on vetting Pais’ ideas indicate that a possible outcome of the plasma fusion device and the high energy levels it may generate is the "Spacetime Modification Weapon” (SMW). Research documents refer to it as “a weapon that can make the Hydrogen bomb seem more like a firecracker, in comparison."
Among Pais’s other inventions with military applications is a patent for an electromagnetic field generator. It could create “an impenetrable defensive shield to sea and land as well as space-based military and civilian assets” which would be used against ballistic and cruise missiles that avoid radars and other defenses. The shield would also be a barrier against dangers from space like coronal mass ejections and wayward asteroids.
Another device that could deflect asteroids is the high-frequency gravitational wave generator conceived by Pais. It would work to intersect generated electromagnetic fields and create waves of gravity. These could be used to propel spaceships to the far reaches of the galaxy, among other uses.
The Pais Effect
The fantastical inventions devised by Dr. Pais largely build upon an idea that he calls “The Pais Effect.” In his patent write-ups and in an interview with The Drive, he described it as “the generation of extremely high electromagnetic energy fluxes (and hence high local energy densities) generated by controlled motion of electrically charged matter (from solid to plasma states) subjected to accelerated vibration and/or accelerated spin, via rapid acceleration transients.”
This effect amounts to the ability to spin electromagnetic fields to contain a fusion reaction. The electromagnetic energy fields would be so powerful that they could “engineer the fabric of our reality at the most fundamental level,” writes Pais.
In practical terms, this invention could lead to a veritable revolution in propulsion, quantum communications, and create an abundance of cheaply-produced energy. Certainly, an extraordinary claim that requires extraordinary evidence, as posits the Sagan standard.
The critics
The assertions by Dr. Pais have drawn a fair share of criticism and incredulity from fellow scientists. The nuclear engineer and researcher Carl Willis, who is also a reactor supervisor at the University of New Mexico, called Dr. Pais’s work, "a classic case of pathological science" that’s heavy on jargon and ”nonsensical statements” while providing little evidence that his ideas, which seem to contradict established physics, can bear fruit.
Physicist Stephen Webb of the University of Portsmouth in England was equally blunt, saying that, “I find it puzzling frankly that the patents were awarded.“ He called Pais’s ideas a, “wonderful wish list of things that we want,” which, “doesn’t make sense in terms of physics.”
Dr. Charles Collett, who teaches Physics at Muhlenberg College, did acknowledge that in theory, the Pais Effect may not be “outlandish” but in practice, there are "significant engineering challenges” in fashioning a device that would be able to produce the kind of electromagnetic forces Dr. Pais envisions in his patents.
The trials
Despite the well-founded unease at Dr. Pais’s inventions, the Navy took them seriously enough to run experiments for three years and even found some of them “operable”, although the extent of that alleged operability is under debate. In the patent documents, two Navy officials seemed to assert the operability of the inventions.
Furthermore, in correspondence with The Drive’s “War Zone,” Timothy Boulay of NAWCAD, stated that Pais’s High Energy Electromagnetic Field Generator was, in fact, tested from 2016 until 2019, at a cost of $508,000. The team working on the project consisted of at least 10 technicians and engineers and put in some 1,600 hours of work. But upon the conclusion of the testing, the Pais Effect “could not be proven,” shared Boulay.
What happened subsequently with the tested device and further investigations is not known at this point. There are indications in documents obtained by The Drive’s WarZone through the Freedom of Information Act that the inventions could be moved to another research department in the Navy or the Air Force, or possibly even to NASA or DARPA, but whether that really happened is not clear.
Who is Dr. Pais?
As a creator of such potentially pioneering designs, Dr. Pais has understandably drawn scrutiny from internet denizens and skeptical scientists but as he rarely gives interviews (partially due to classified research for the military), he has remained largely enigmatic.
His author bio in a 2019 concept paper on the Plasma Compression Fusion Device, published by the peer-reviewed engineering journal IEEE Transactions on Plasma Sciences, provides some clues. The paper proposes a compact plasma compression fusion device that seeks to generate tremendous energy through nuclear fusion and describes Dr. Pais as a mechanical and aerospace engineer who currently works for the Navy’s Strategic Systems Programs (SSP) in the Department of Defense in Washington, DC. According to its website, the SSP is “the Nation's premier provider of cost-effective, safe and secure sea-based strategic deterrent systems and related technologies.” It works to develop advanced submarines and weapons for the stated mission “to prevent nuclear war.”
Dr. Pais’s education includes a Ph.D. from Case Western Reserve University in Cleveland, Ohio and his prior credentials include work as a NASA Research Fellow, working for the Naval Air Warfare Center Aircraft Division (NAWCAD) in Maryland, and work as a general engineer as well as an advanced concept analyst for Northrop Grumman Aerospace Systems, one of the world’s top companies for next-generation aerospace and defense technologies.
Dr. Pais, claims the bio, utilizes his “advanced knowledge” in aerodynamics, with particular expertise in designing hypersonic missiles and vehicles. His wide-ranging research interests also extend to electrical engineering, room temperature conductivity, and new quantum technologies with a concentration on laser power generation and high-energy electromagnetic field generation.
The inventor’s credentials are definitely impressive. Did he come up with devices that not only defy known physics and physicists but will radically change our life through limitless energy and high-speed all-medium vehicles? Time will tell, but in his exchanges with The Drive, Dr. Pais stands by his technological visions and asks the skeptics to “try to keep an open mind in regard to my work.”
A supermassive black hole 13.1 billion light years from Earth is driving the earliest known example of a titanic storm with winds travelling at 1.1 million miles per hour.
Researchers using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile discovered the winds driven by the black hole 800 million years after the Big Bang.
This titanic storm is a telltale sign these huge black holes at the centre of galaxies have a 'profound effect' on the growth of galaxies from the early universe, say astronomers from the National Astronomical Observatory of Japan (NAOJ)
The team say this is the earliest-yet-observed example of this type of storm coming from a black hole that is millions to billions of times more massive than the Sun.
A supermassive black hole 13.1 billion light years from Earth is driving the earliest known example of a titanic storm with winds travelling at 1.1 million miles per hour
SUPERMASSIVE BLACK HOLES ARE AT THE HEART OF GALAXIES
Supermassive black holes are objects found at the heart of most galaxies.
They have a mass millions to billions of times the mass of the Sun and allow nothing to escape, not even light.
In the Milky Way the supermassive black hole is known as Sagittarius A*.
There is also a class of ultramassive black holes, with a mass of at least 10 billion times the mass of the son.
Even larger ones, with 100 billion times the mass of the sun have been dubbed stupendously large black holes.
Sitting at the centre of many large galaxies, including our own Milky Way, there is a supermassive black hole and some are more active than others.
They found that the mass of the black hole is roughly proportional to the mass of the central region - or bulge - of the galaxy it inhabits.
'At first glance, this may seem obvious, but it is actually very strange,' the authors of the study explained, adding that the sizes of galaxies and black holes differ by 10 orders of magnitude - with galaxies significantly larger.
'Based on this proportional relationship between the masses of two objects that are so different in size, astronomers believe that galaxies and black holes grew and evolved together through some kind of physical interaction,' they wrote.
A galactic wind can provide this kind of physical interaction between black holes and galaxies - with larger winds impacting galactic growth.
A supermassive black hole swallows a large amount of matter. As that matter begins to move at high speed due to the black hole's gravity it emits intense energy, which can push the surrounding matter outward. This is how the galactic wind is created.
'The question is when did galactic winds come into existence in the Universe?' says Takuma Izumi, the lead author of the research paper.
'This is an important question because it is related to an important problem in astronomy: how did galaxies and supermassive black holes coevolve?'
Using the Subaru Telescope's wide-field, they found more than 100 galaxies with supermassive black holes in the Universe more than 13 billion years ago.
Then, the research team utilised ALMA's high sensitivity to investigate the gas motion in the host galaxies of the black holes.
Researchers using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile discovered the winds driven by the black hole 800 million years after the Big Bang
WHAT IS ALMA?
Deep in the Chilean desert, the Atacama Large Millimetre Array, or ALMA, is located in one of the driest places on Earth.
At an altitude of 16,400ft, roughly half the cruising height of a jumbo jet and almost four times the height of Ben Nevis, workers had to carry oxygen tanks to complete its construction.
Switched on in March 2013, it is the world's most powerful ground based telescope.
It is also the highest on the planet and, at almost £1 billion ($1.2 billion), one of the most expensive of its kind.
ALMA observed galaxy HSC J124353.93+010038.5, and captured radio waves emitted by the dust and carbon ions in the galaxy.
Detailed analysis of the ALMA data revealed that there is a high-speed gas flow moving at 500 km per second in J1243+0100 or 1.1 million miles per hour.
This gas flow has enough energy to push away the stellar material in the galaxy and stop stars from forming.
It is the oldest observed example of a galaxy with a huge wind of galactic size. The previous record holder was a galaxy about 13 billion years ago; so this observation pushes the start back another 100 million years.
The team also measured the motion of the quiet gas in J1243+0100, and estimated the mass of the galaxy's bulge, based on its gravitational balance, to be about 30 billion times that of the Sun.
The mass of the galaxy's supermassive black hole, estimated by another method, was about 1 per cent of that, suggesting the new method could be more accurate.
The mass ratio of the bulge to the supermassive black hole in this galaxy is almost identical to the mass ratio of black holes to galaxies in the modern Universe.
This titanic storm is a telltale sign these huge black holes at the centre of galaxies have a 'profound effect' on the growth of galaxies from the early universe, say astronomers from the National Astronomical Observatory of Japan (NAOJ)
This implies that the coevolution of supermassive black holes and galaxies has been occurring since less than a billion years after the birth of the Universe.
'Our observations support recent high-precision computer simulations which have predicted that coevolutionary relationships were in place even at about 13 billion years ago,' comments Izumi.
'We are planning to observe a large number of such objects in the future, and hope to clarify whether or not the primordial coevolution seen in this object is an accurate picture of the general Universe at that time.'
BLACK HOLES HAVE A GRAVITATIONAL PULL SO STRONG NOT EVEN LIGHT CAN ESCAPE
Black holes are so dense and their gravitational pull is so strong that no form of radiation can escape them - not even light.
They act as intense sources of gravity which hoover up dust and gas around them. Their intense gravitational pull is thought to be what stars in galaxies orbit around.
How they are formed is still poorly understood. Astronomers believe they may form when a large cloud of gas up to 100,000 times bigger than the sun, collapses into a black hole.
Many of these black hole seeds then merge to form much larger supermassive black holes, which are found at the centre of every known massive galaxy.
Alternatively, a supermassive black hole seed could come from a giant star, about 100 times the sun's mass, that ultimately forms into a black hole after it runs out of fuel and collapses.
When these giant stars die, they also go 'supernova', a huge explosion that expels the matter from the outer layers of the star into deep space.
A new study finds the oldest galactic wind yet detected, from 13.1 billion years ago.
The research confirms the theory that black holes and galaxies evolve together.
The galactic wind was spotted using the Atacama Large Millimeter/submillimeter Array in Chile.
An enormously powerful galactic wind generated by a supermassive black hole 13.1 billions years ago has been discovered by researchers. The scientists used the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, which combines 66 radio telescopes, to make the find. The results are published in the Astrophysical Journal.
This is the earliest example of this type of wind yet spotted that underscores the role of black holes in the formation of galaxies. Research has shown that galactic winds affect redistribution of metals around the galaxy and impact start formation.
Black holes and galaxies evolve together
In previous studies, scientists have noticed an unexpected proportional relationship between the mass of a supermassive black hole at the center of a large galaxy, which can grow up to billions of times more massive than the sun, and the mass of the galaxy’s central area (known as a “bulge”). The proportionality of the masses is especially unusual considering that galaxies and black holes are so different in size, with the bulge generally being orders of magnitude larger. This led the researchers to conclude that galaxies and black holes developed together through coevolution, which involved some physical interaction courtesy of the galactic wind.
As ALMA’s press release explains, a galactic wind starts coming into existence when a supermassive black hole gobbles up giant quantities of matter. It is then moved at such a high speed by the black hole’s gravity that it radiates intense energy, which in turn, pushes surrounding matter away, creating the galactic wind.
Takuma Izumi, the paper’s lead author and a researcher at the National Astronomical Observatory of Japan (NAOJ), says an important question is: “When did galactic winds come into existence in the universe?” Finding this out can lead to understanding how galaxies and supermassive black holes coevolved.
The researchers used NAOJ’s Subaru Telescope to locate over 100 galaxies that existed more than 13 billion years ago that featured supermassive black holes. They then used the high sensitivity of ALMA to analyze the gas motion in these galaxies, finding that the dust and carbon of one of them (dubbed J1243+0100) emitted radio waves. This allowed the scientists to detect the presence of an intense galactic wind that rushes forth from the supermassive black hole at about 1,118,468 miles per hour (500 km/second). The energy of the wind, the oldest found so far, is so strong that it pushes away stellar materials, preventing stars from forming.
Interestingly, the mass of the bulge in J1243+0100 was found to be about 30 billion times larger than that of the sun, while the mass of the galaxy’s supermassive black hole was estimated to be about 1 percent of that. This ratio is essentially the same as the mass ratio of black holes to galaxies in today’s universe. To the scientists, this demonstrates how essential black holes are in affecting the growth of galaxies, supporting the notion of coevolution from the early period of the universe.
“Our observations support recent high-precision computer simulations which have predicted that coevolutionary relationships were in place even at about 13 billion years ago,” explained Izumi.
The scientists are planning to observe a large pool of space objects in the future, with the goal of clarifying “whether or not the primordial coevolution seen in this object is an accurate picture of the general universe at that time,” further commented Izumi.
Verblijf in de ruimte verandert je hersenen voor langere tijd: "Had niemand verwacht”
Verblijf in de ruimte verandert je hersenen voor langere tijd: "Had niemand verwacht”
De hersenen van astronauten veranderen als ze voor een lange tijd in de ruimte verblijven. Dat blijkt uit een studie van het European Space Agency (ESA) en het Russische ruimteagentschap Roskosmos. “Astronauten moeten nieuwe vaardigheden aanleren door de gewichtloosheid en dat zie je in hun hersenen.”
Glenn Haex
Het internationale onderzoeksteam bestudeerde de hersenen van twaalf mannelijke astronauten die een langere tijd in de ruimte hadden verbleven. Hun hersenen werden vóór de vlucht, vlak na de vlucht en zeven maanden na hun terugkeer onderzocht met MRI-scans. “De veranderingen die het team waarnam, waren heel nieuw en onverwacht”, zegt prof. Floris Wuyts van de UAntwerpen.
Zowel de neuronen als de verbindingen tussen de neuronen in de hersenen waren toegenomen. Ook was er heel wat hersenvloeistof verschoven. Die vloeistof zorgt bovendien voor hervormingen in onder andere het corpus callosum, “de centrale snelweg die beide hersenhelften verbindt”.
Gewichtloosheid
Ook zeven maanden na de ruimtereis, waren de veranderingen nog steeds zichtbaar: “De veranderingen zijn weliswaar verminderd, doordat de astronauten opnieuw gewend geraken aan de zwaartekracht. Maar dat de effecten van de ruimtereis zo lang na terugkomst nog duidelijk te zien zouden zijn, dat had niemand verwacht”, aldus Wuyts.
We weten niet wat deze veranderingen op lange termijn zullen betekenen
Floris Wuyts, Labo voor Evenwichtsonderzoek en Aerospace (LEIA)
Oorzaak van de veranderingen is de gewichtloosheid tijdens de ruimtereis, waardoor de astronauten nieuwe vaardigheden moeten aanleren. Dat zie je namelijk in de hersenen. Of die veranderingen effect hebben in hun dagelijks leven – of ze bijvoorbeeld slimmer zijn geworden of vloeiender gaan bewegen – is nog niet geweten.
Langetermijneffecten
Ook het effect die de veranderingen in de hersenen op de langere termijn hebben, is nog niet bekend. “De onderzochte groep is te klein om daar al informatie over te hebben of voorspellingen te kunnen doen”, vertelt Wuyts. “Op termijn zullen we mensen voor langere tijd de ruimte insturen, zoals voor een verblijf op Mars. Het is essentieel dat we op voorhand al een nauwkeurige inschatting kunnen maken van de verwachte effecten, zodat we de nodige tegenmaatregelen kunnen treffen om deze effecten te minimaliseren.”
Onderzoekers hebben ontdekt dat microzwaartekracht de hersenen kan doen opzwellen en de hypofyse kan vervormen.

Dino’s stierven uit in de lente: “Was op een gevoelig moment”
Dino’s stierven uit in de lente: “Was op een gevoelig moment”
De meteoor die 66 miljoen jaar geleden bijna alle niet-vliegende dinosauriërs uitroeide, stortte op de aarde neer in de lente. Dat blijkt uit het groei- en eetpatroon van vissen die meteen na de meteoorinslag stierven. “We konden het duidelijk zien bij röntgenfoto’s van enkele fossiele steuren”, zegt de Belgische onderzoeker Koen Stein.
Glenn Haex
Paleontologen zijn het erover eens dat een meteoorinslag op het huidige schiereiland Yucatán in Mexico zo’n 66 miljoen jaar geleden het eind inluidde van de niet-vliegende dinosauriërs. Dit staat ook bekend als de vijfde massa-uitsterving.
“Die inslag deed de continentale plaat beven en veroorzaakte grote golfslagen in rivieren en andere waterlichamen. Dat maakte enorme hoeveelheden sediment los die vissen levend begroeven”, zegt Melanie During van de VU Amsterdam en Uppsala University. “Intussen regende het kleine glasachtige bolletjes: gesmolten steentjes die uit de inslagkrater waren weggeschoten, in de lucht verglaasden en een paar duizend kilometer verder neerkwamen.”
Bewijs voor lente
Die bolletjes vonden de onderzoekers terug in de kieuwen van enkele fossiele steuren in de Amerikaanse site Tanis, in North Dakota. Dat is onmiddellijk bewijs van hun dood kort na de meteoorinslag. “Ze waren heel duidelijk te zien op röntgenscans”, zegt VUB-onderzoeker Koen Stein. Op de scans konden de wetenschappers bovendien zien in welk seizoen de vissen stierven: “We bestudeerden de interne botstructuur van zes fossiele steuren. Daaraan kun je de seizoensgebonden groei aflezen, net zoals bij bomen. Deze vissen stierven toen het op het noordelijk halfrond lente was.”
Ook de botcellen van de vissen bevestigen deze theorie: hun grootte en dichtheid veranderen ook onder invloed van de seizoenen. “In alle visfossielen konden we de botceldichtheid en -grootte over verschillende jaren heen analyseren. In het jaar van de meteoorinslag waren ze groter aan het worden, maar hadden ze de piek nog niet bereikt”, zegt Dennis Voeten van Uppsala University.
Gevoelig moment
“We mogen hieruit echt concluderen dat ‘de grote dood’ in de lente kwam”, zegt During. “Dat was op een gevoelig moment, want in de lente start bij veel dieren de voortplantingscyclus. De incubatietijd bij reptielen zoals dinosauriërs en pterosauriërs is ook langer dan bij andere diergroepen, zoals vogels, dus waren zij mogelijk gevoeliger voor die plotse verstoring van hun omgeving.”
Ook verklaart het waarom sommige diersoorten de vernietigende meteoorinslag wel overleefde. In het zuidelijk halfrond was het namelijk herfst: “Dieren die toen al ondergronds aan hun winterrust begonnen waren, onder meer sommige vroege zoogdieren, kunnen zo de eerste maanden na de meteoorinslag, met grootschalige bosbranden, hebben overleefd”, aldus During.

Awesome Glowing UFO Seen Off Coast Of Sicily, Italy Feb 24, 2022, Video, UFO Sighting News.
Awesome Glowing UFO Seen Off Coast Of Sicily, ItalyFeb 24, 2022, Video, UFO Sighting News.
Date of sighting: Feb 24, 2022
Location of sighting: Trabia Commune in Sicily, Italy
The eyewitness was on the coast of Sicily when he noticed a huge flashing sphere. The sphere would appear normal and then suddenly flash as if it were trying to communicate to the person. The UFO is over far out over the ocean, hovering low, yet the object is powerfully lit up. Very cool and rare sighting in Italy.
What most people don't know is that they are just a few hundred km from the location of the famous Rocca Pia, Italy UFO case which lasted three decades...a case that involved human alien meetings and interactions. As you see Trabia city is facing the ocean...where part of the alien base exists. Aliens said the base holds about ten thousand people of different species. They also said the base is so big, it extends from below Rocca Pia all the way out into the ocean for 20km. Thats one big underground base! Just food for thought. More info on the Rocca Pia case here...

Flashing Orb Seen Over Yukon, Canada On Feb 24, 2022, video, UFO Sighting News.
Date of sighting: Feb 24, 2022 Location of sighting:Yukon, Canada
This eyewitness noticed a brightly glowing and fluctuating orb in the sky in Canada yesterday. The object seemed to be very close. I estimate it to be about 100-150 meters away from the eyewitness. As he watches and records it, you can hear his excitement when it flashes to him. The UFO does this to tell the person that it too noticed you. Kind of amazing experience, sadly the video is very short, but even a short video gives us great evidence. Undeniable proof that UFOs exist.
Possible craft parked on landing platform in Antarctica
Possible craft parked on landing platform in Antarctica
It could just be just a natural formed part of Antarctica's ice sheet but it looks like a craft parked on a rectangular landing platform in front of an entrance.
The Magellan probe sent to Venus that operated in the late 80s and 90s, collected an enormous amount of images that have finally been published by NASA in which huge cities, artificial structures and all kinds of elements that seem to obey constructions appear intelligent effected by some kind of alien race that inhabited or colonized the second planet in our solar system.
In the following video, we show those buildings that we have found and their interpretations in 3 Dimensions of them.
