Chinese Rover Discovers It’s Sitting on 39 Feet of Moon Dust
Chinese Rover Discovers It’s Sitting on 39 Feet of Moon Dust
Researchers at the Chinese Academy of Sciences in Beijing have started analyzing data collected by the country’s Yutu-2 Moon rover’s ground-penetrating radar. The instrument peered 40 meters (131 feet) below the lunar surface — and found it was sitting on top of a mountain of fine dust.
China’s Chang’e 4 lander touched down on the far side of the Moon in January 2019, becoming the first man-made object to do so. Shortly after, it deployed the rover Yutu-2 from its belly. The rover has been exploring the South Pole-Aitken basin, the largest and oldest crater on the Moon, ever since.
Using high-frequency radar to look beneath the surface, it found that it was sitting on top of 12 meters (39 feet) of fine Moon dust, as detailed in a paper published in the journal Science Advances on Wednesday.
“That’s a lot of regolith,” David Kring, senior scientist at the Lunar and Planetary Institute in Houston who was not involved in the research, told The New York Times. “That’s food for thought.”
The fine particles were likely the result of many small meteorite collisions and a ton of solar radiation, as New Scientist reports.
Below the dust, between 12 and 24 meters (39 and 79 feet), the rover spotted larger rocks, likely what’s left of larger asteroid and meteorite impacts. Further below that, the rover detected alternating layers of fine and coarser soil.
Most noteworthy is the striking difference between the new readings and the ones taken at Chang’e 4’s landing site, where measurements suggested it landed on top of a dense lava layer buried below the surface, the remains of a volcanic event.
“The subsurface structure at the Chang’e 4 landing site is more complex, and suggests a totally different geological context,” Yan Su, co-author from the Chinese Academy of Sciences, told New Scientist.
Nasa films mystery UFO following the International Space Station for 20 minutes
Nasa films mystery UFO following the International Space Station for 20 minutes

The strange ‘cone-shaped’ UFO following the ISS
(YouTube/ET Data Base)
Cameras on board the International Space Station (ISS) have picked up a strange, cone-shaped object in orbit around Earth.
The unexplained object seemingly keeps pace with the space station as the cameras remain locked on it for over 20 minutes.
Naturally, the footage has been picked up and circulated around parts of the internet dedicated to discussing alien technology. Fanning the conspiracy flames even further, the camera zooms in on the object at one point suggesting that Nasa is aware of its presence.
For the bus-sized object to keep pace with the ISS, it would need to be travelling at around 7.8 kilometers-per-second.
The footage was picked up and shared on a YouTube channel called ET Data Base hosted by noted UFO-watcher Scott C. Waring
‘That is NASA zooming in on the UFO, not me,’ Waring notes of the footage. ‘They are as baffled by it as I am. They don’t know what it is or why it is there.’
While it’s highly unlikely to be evidence of any kind of alien encounter, the idea of it being military technology isn’t that far fetched.
The US Air Force has a small, autonomous plane called X-37B that conducts intelligence operations from orbit. Built by Boeing and flown remotely, the craft – also known as Orbital Test Vehicle – is on a mission the U.S. will only describe as ‘classified’.
It is able to stay aloft for months at a time and comes down infrequently for servicing.

In Britain, the RAF took the decision to wind up its UFO unit in 2009, after concluding that in more than 50 years, no received report had ever disclosed any evidence of a potential threat.
Nothing scares the powers that be who create the power that’s being consumed by everyone more than free power for all. Well, if you’re one of those powers, get ready for the non-electrical shock of your life … engineers at the University of Massachusetts Amherst have invented a generator that runs on air. Air is still free … right? Better start filling up some balloons, just in case.
“It’s the most amazing and exciting application of protein nanowires yet.”
Who knew there were ANY applications for protein nanowires? This is truly a ‘making something from almost nothing’ story from the very beginning. As described in an article in the journal Nature, electrical engineer Jun Yao and microbiologist Derek Lovely were actually working on something else two years ago when a graduate student working with protein nanowires in their lab noticed that nanometer-width rod-shaped proteins called Geobacter sulfurreducens (created by the bacteria Geobacter) seemed to be emitting electrical current without being connected to a power source. These Geobacter sulfurreducens had a truly humble beginning – they were first isolated in Norman, Oklahoma, from materials found around the surface of a contaminated ditch.
After further experimentation, Yao and Lovely determined that the nanowires were pulling moisture from the air and pushing it through a film of nanowires pressed between two electrodes. That push varied the amount of electrical charge in the film, which generated a charge that the electrodes picked up. The team found that between 40-50 percent relative humidity is ideal for the nanowire generators, but they can produce detectable voltages between 20-100 percent relative humidity (even the Sahara Desert falls in that range). According to their summary in Device & Materials Engineering, one pair of electrodes generates .5 volts and a string of five puts out 2.5 volts. Would that scale hold true if thousands or even millions were chained together?
Yes … provided that could find sufficient amounts of Geobacter sulfurreducens nanowires. There aren’t enough contaminated ditches in Norman, so Lovely is leading separate research to use E. coli for something good for a change – growing protein nanowires. So far, the E. coli nanowires are as conductive as those produced with G. sulfurreducens. With E. coli everywhere, how far are we from giant air-sucking generators?
“The ultimate goal is to make large-scale systems. For example, the technology might be incorporated into wall paint that could help power your home. Or, we may develop stand-alone air-powered generators that supply electricity off the grid. Once we get to an industrial scale for wire production, I fully expect that we can make large systems that will make a major contribution to sustainable energy production.”
Lovely predicts this will happen soon. The team is so confident, they’ve already named the environmentally-friendly nanowire device “Air-gen.” All they need now is funding for the development, funding for the marketing and funding for the inevitable lawsuits by the conventional non-renewable energy power companies.
Did the whale oil makers sue when oil was discovered? Probably.
It hasn’t been six months since the fiasco that was Storm Area 51 – even if you personally enjoyed the music portion of what was originally (albeit satirically, at least in its initial form) supposed to be a mass human mob crashing the gates of the secret base in numbers that the military could not deal with nor exterminate without raising some suspicions. The movement’s mission was to free captive aliens, but there didn’t seem to be much of a plan as to what to do after getting past the first gate/fence – the only person to actually “storm” was a 60-year-old woman who was arrested, charged with trespassing and released. Well, stormers, you now have some secret entrances to target for your next gate-crashing. Who’s bringing the alien beer this time?
Google Earth (Area 51 Facility) Coordinates: • 37°14′0″N 115°48′30″W
Those coordinates come from Google Earth by way of the YouTube site FindingUFO, which didn’t find any UFOs but did locate three suspicious spots that appear to be secret tunnel openings near the main grounds of Area 51. However, it didn’t just post and run – the folks at FindingUFO did some serious digging and located previous satellite images of the three mysterious sets of openings and put together a reverse time-lapse video showing their evolution from today back to 1998. (Watch it here.)
“Yep, there are a lot of those underground hangers or storage bunkers out there around Area 51 and S4. The cover story is that they are openings to large industrial mines.”
Uploaded on February 21, the video, entitled “Hidden Underground Area 51 Base Entrances Discovered in Mountains (Google Earth),” immediately generated comments ranging from the subterranean to the ridiculous. It seems reasonable to suggest that this former mining area could still have open entrances which would save the government the trouble of digging more tunnels for … what? Nuclear waste storage (one suggestion) doesn’t make sense in an area so close to large manned facilities.
An “underground transport network” is an interesting idea, considering there are vehicles parked around the openings. Quick escape routes in case of some catastrophe in the secret hangars or labs? If that’s the case, these would be more recent projects, not repurposed mines. And wouldn’t the openings be much larger to possibly handle experimental aircraft? The apparent size of the openings suggests they’re not for large-scale escapes or secret launches either.
Could these tunnels be used for another Storm Area 51 event … assuming the masses get past the main gate? (BTW — we’re not promoting a storming, just asking questions.) The photos don’t seem to show any external protection or guards, but anyone with imagination or cable TV knows that they’d probably encounter massive doors of super-strong metals and security systems that locksmiths, dynamite or AI-generated fake IDs wouldn’t likely allow them past.
So, not good openings for storming, but definitely good openings for discussions on what else they might be … not to mention more searches of Area 51 with Google Earth. Which leads to the obvious question … if the lace is so secret, why let Google Earth satellites take pictures of it?
Begin “it’s a decoy to lure eyes away from Site S4” discussion here. Paging Bob Lazar. And thanks again to FindingUFO.
In November of 2004, the U.S. Navy USS Nimitz Carrier Strike Group was on combat training maneuvers in the Pacific Ocean, just about 100 miles off the coast of San Diego, California, in order to prepare for upcoming deployment to the Persian Gulf. This was not unusual in and of itself, and it was a perfectly normal series of operations they were engaged in, but things would soon get very weird indeed, and would launch one of the strangest and most talked about military UFO encounters on record.
It was all supposed to be a routine combat training exercise, but things would soon get strange when over a period of several days the Ticonderoga-class guided missile cruiser USS Princeton began picking up frequent radar signatures of unidentified aircraft of some sort on their cutting edge AN/SPY-1B passive scanning phased array radar. These objects were very odd in that they were numerous and seemed to be travelling at an altitude of up to 80,000 feet, far beyond what any normal aircraft would be operating at. The radar hits were very persistent and happened often, with well over 100 of the objects supposedly tracked over the course of the week, usually in formations of up to 8 to 10 at a time, and it was so odd that the radar operators at first thought it had to be some sort of equipment glitch, yet they recalibrated everything and it was all found to be in working order. At times the crew would try and get some sort of visual confirmation of what they were picking up but it was difficult to make out clearly even with binoculars. Whatever it was, it was certainly strange, and one of the radar operators, Petty Officer 3rd Class Gary Voorhis, would later say of the objects:
Once we finished all the recalibration and brought it back up, the tracks were actually sharper and clearer. Sometimes they’d be at an altitude of 80,000 or 60,000 feet. Other times they’d be around 30,000 feet, going like 100 knots. Their radar cross sections didn’t match any known aircraft; they were 100 percent red. No squawk, no IFF (Identification Friend or Foe). When they’d show up on radar. I’d get the relative bearing and then run up to the bridge and look through a pair of heavily magnified binoculars in the direction the returns were coming from. I couldn’t make out details, but they’d just be hovering there, then all of a sudden, in an instant, they’d dart off to another direction and stop again. At night, they’d give off a kind of a phosphorus glow and were a little easier to see than in the day.
The crew continued to keep their eye on the phenomena until they were alarmed to see that some of the objects seemed to at times carry out rapid descents in altitude that took them well into commercial airspace, and this was where things would get weird. On November 14, 2004, it was decided that some sort of action should be taken, and two F/A-18F Super Hornet fighter jets from the USS Nimitz piloted by Commander David Fravor and Lt. Commander Jim Slaight were told to break off from their training maneuvers in order to go investigate an object that had appeared to drop towards the ocean surface on radar. Although they were not carrying live weaponry, the fighters were told to fly by and see if they could make visual confirmation of anything out there and report back. It was clear, calm weather, and the pilots were certain that if there was anything to this then they would soon figure out what the mysterious object was, and they were not wrong. The problem is, it was far from what any of them had imagined.
As they scanned the area the pilots allegedly saw something causing a disturbance in the water, where it seemed as if the waves were breaking over an oval shape under the surface. At precisely the time they noticed this odd sight, a bright, white object shaped like a “Tic-Tac” reportedly suddenly appeared nearby, hovering around 50 feet over the water. This startling object was estimated as being around 30 to 46 feet long, and oddest of all was that it had no noticeable ports, windows, rotors, wings, or any visible method of propulsion. The pilots attempted to approach the craft, after which it launched into a breathtaking display of maneuvers and erratic movements which seemed to defy physics, of which Fravor would say, “This thing would go from one way to another, similar to if you threw a ping-pong ball against the wall.” It then sped away with a rate of acceleration that left the experienced pilots in awe.
The pilots tried to pursue the “Tic-Tac,” but it accelerated at an astronomical rate, and according to Fravor “was just gone.” Oddly, the object soon after appeared around 60 miles away near the combat air patrol (CAP) rendezvous point “within seconds,” suggesting that it was travelling at speeds twice as fast as the F-18s and an estimated three times the speed of sound, the whole time demonstrating what was called “an advanced acceleration, aerodynamic, and propulsion capability.” Other fighters were launched in response, but the object soon sped away again to disappear. Fravor was so impressed by the object that he would later say, “I have no idea what I saw. It had no plumes, wings or rotors and outran our F-18s. But I want to fly one.” Another wingman who was with them at the time would comment, “It was so unpredictable—high G, rapid velocity, rapid acceleration. So you’re wondering: How can I possibly fight this?” Other witnesses to the event were equally as baffled as the pilots, with one Petty Officer 3rd Class Jason Turner later saying of the object and its physics defying display:
This thing was going berserk, like making turns. It’s incredible the amount of g forces that it would put on a human. It made a maneuver, like they were chasing it straight on, it was going with them, then this thing stopped turning, just gone. In an instant.
The whole incident was causing a big stir at the time, and making it all even more impressive was that one of the fighters in the second wave of pilots had managed to capture footage of the object with an infrared camera system, called a FLIR pod, but this would be kept under wraps for years. In fact, the USS Nimitz UFO encounter would largely be buried and kept from the public until 2017, when a clip of the footage was acquired and leaked by a UFO organization called the To the Stars Academy, which co-founded by Blink-182 frontman and kajor UFO buff Tom DeLonge, followed by an article the New York Times ran on the incident, and it all immediately caused a firestorm of debate and discussion. Was it real, was this a hoax? No one knew, but everybody seemed to be talking about it.
The footage made major waves at the time, and this was all ramped up when the U.S. Navy finally admitted that the footage was indeed real, that it had indeed been taken by infrared cameras aboard their aircraft, and even released further clips of the incident, complete with audio of the pilots marveling over what they are looking at. The Navy also said that they were putting new protocols into effect for dealing with unidentified craft encountered by pilots in incidents such as this and others like it, as well as that they were funding a program called the Advanced Aerospace Threat Identification Program.
Even with this official release of information the conspiracy theories swirled that this was only the tip of the iceberg, and that they were in possession of longer video footage and other data on the incident. This would only be fanned by an investigation into the incident carried out by Popular Mechanics, which interviewed numerous people who had been involved in the event and uncovered evidence that there were some shady things going on in the wake of the incident. One anonymous witness they managed to track down identified as an Operations Specialist aboard the USS Princeton at the time would give a comment on the incident and explain that much of the data was suddenly seized and whisked away, saying:
I do remember the events of 2004 very well. The decision was made to scramble two fighter jets to investigate. From what the pilots described, the movement of the UFO was defying the laws of physics. What really made this incident alarming was when a Blackhawk helicopter landed on our ship and took all our information from the top secret rooms. We were all pretty shocked and it was an unspoken rule not to talk about it because we had secret clearances and didn’t want to jeopardize our careers.
A still from the USS Nimitz footage
This was corroborated by others who were present, such as the radar operator Voorhis, who also said that a helicopter landed and he was told to hand over all the data recordings for the AEGIS system. Others have also insisted that a substantial amount of the 8mm footage of the incident was confiscated by this unknown party, and insist that what was released is only snippets. This has only furthered conspiracy theories and discussion surrounding the event, and the USS Nimitz UFO encounter is just as mysterious as it has ever been, the Navy very tight-lipped about offering any official statement on what is seen in the videos and wary of any speculation on the matter, merely saying that what is seen in the videos is unidentified.
This of course has not stopped widespread speculation on the incident, and various theories have been proposed for the mysterious object and what the pilots experienced. One idea is that this is indicative of perhaps some sort of top-secret aircraft or advanced reconnaissance drone test, utilizing never-before-seen technology. This seems plausible on the surface, but if that were the case why would it be tested so close to where a carrier fleet was in the middle of performing military combat exercises? There is also the fact the most researchers, journalists, and military personnel willing to talk about it are adamant that no one has technology anywhere near what was reported and what is seen in the videos. Other ideas are that this was all due to equipment malfunction, pilot error, or even weather balloons or some misidentified natural atmospheric phenomena, but this is all still unsatisfactory as the incident was witnessed by numerous highly qualified personnel and pilots and was observed both visually and with corroborating radar. It is this perfect blend of photographic evidence and highly reliable witnesses that has made the case so persistent. What happened out there during that training mission? Was this drones, experimental aircraft, pilot error, or something not of this world? No matter what the real answer may be, the USS Nimitz UFO encounter remains one of the most spectacular, well-documented military accounts there is, and has remained very much discussed.
It's summer in Antarctica, which means record-high temperatures, jarring glacial melt and — in a very metal symbol of our changing climate — a bit of blood-red snow spattered across the Antarctic Peninsula.
Over the past several weeks, the ice around Ukraine's Vernadsky Research Base (located on Galindez Island, off the coast of Antarctica's northernmost peninsula) has been coated in what researchers are calling "raspberry snow." A Facebook post by the Ministry of Education and Science of Ukraine shows the scene in full detail: streaks of red and pink slashing across the edges of glaciers and puddling on the frosty plains.
That blood (or "jam" as the researchers whimsically call it) is actually a type of red-pigmented alga called Chlamydomonas Chlamydomonas nivalis, which hides in snowfields and mountains worldwide. The algae thrive in freezing water and spend winters lying dormant in snow and ice; when summer comes and the snow melts, the algae bloom, spreading red, flower-like spores.
This phenomenon, which Aristotle noticed way back in the third century B.C., is known as "watermelon snow," "blood snow" and a host of other less poetic names.
The phenomenon's red color comes from carotenoids (the same pigments that make pumpkins and carrots orange) in the algae's chloroplasts. In addition to their crimson hue, these pigments also absorb heat and protect the algae from ultraviolet light, allowing the organisms to bask in the summer sun's nutrients without risk of genetic mutations.
That's good for the algae but not great for the ice. According to the Ukrainian researchers, it’s easy for these blooms to kick off a runaway feedback loop of warming and melting.
"Snow blossoms contribute to climate change," the team wrote in the Facebook post. "Because of the red-crimson color, the snow reflects less sunlight and melts faster. As a consequence, it produces more and more bright algae."
The more heat the algae absorbs, the faster the surrounding ice melts. The more ice that melts, the faster the algae can spread. That, in turn, leads to more warming, more melting, and more algal blooming.
A similar feedback process is driving more extreme algal blooms in oceans all over the world, resulting in surreal scenes like an invasion of sea foam in Spain and blue, bioluminescent "tears" clinging to China's coasts. While watermelon snow has existed for millions of years, algal blooms thrive in warm weather, meaning we can probably expect to see more events like this as the climate changes.
The year 2020 has not started off well for the continent of Antarctica. In early February, the highest temperature in recorded history was reached 64.9 degrees Fahrenheit (18.3 degrees Celsius). A few days later, an iceberg the size of the U.S. city of Atlanta broke off of the Pine Island Glacier – one of the most watched chunks of ice on the planet because it has been calving frequently and these plus future icebergs are raising the ocean level. If that weren’t enough, this week the Ukrainian Antarctic station “Academician Vernadsky” was hit by the classic Fortean phenomena of blood red snow. Are these signs? Should we be worried? Who do we believe?
“For a few weeks, the Ukrainian Antarctic station “Academician Vernadsky” has been otočena… raspberry snow!” (Google translation)
The Ministry of Education and Science of Ukraine posted pictures and information about the red snow on its Facebook page on February 24. (Other pictures here.) To prevent any panic or misinterpretation of the “raspberry” snow and ice, the Ministry gave the biological explanation for the phenomena.
“Our scientists have identified them under a microscope as Chlamydomonas nivalis chlamydomonas.”
“Because, besides green pigment – chlorophyll, their cells contain also a red carotene layer, red spots occur on snow as if from raspberry jam. By the way, this layer protects algae from ultraviolet radiation.”
Chlamydomonas nivalis chlamydomonas
Yes, red snow is a good thing … at least for the algae giving it that color. Summer is nearing an end in Antarctica, so the algae needs all the red color it can generate to protect itself. That’s especially true this summer with the record high temperatures. Climate change?
“”Blossom” of snow contributes to climate change. Because of red-raspberry coloring, snow less hitting sunlight and melts faster. As a result, it forms more bright seaweed.”
It’s both a cause and effect of climate change. If anyone would know this, it’s the scientists at Vernadsky Research Base, the only Ukrainian Antarctic station, whose mission is research geophysics, meteorology, and ionospherics using meteorology, upper atmospheric physics and studies of geomagnetism, ozone, seismology, glaciology and more. The 12-person base was opened by the UK in 1947 as Faraday Station and is a center for long-term temperature studies. According to a 2013 report on daily observed temperatures from 1947 to 2011, we’ve got bigger problems than raspberry snow.
“Faraday/Vernadsky is experiencing a significant warming trend of about 0.6°C/decade (1.1°F) over the last few decades. Concurrently, the magnitude of extremely cold temperatures has reduced.”
So yes, the red snow is biological, not Fortean, and it’s a sign.
WETENSCHAPDe aarde is een tweede maan rijker, al is het ding niet veel groter dan een auto. Bovendien verlaat ze haar baan rond onze planeet al over twee maanden.
Astronomen Kacper Wierzchos en Teddy Pruyne, van het door de NASA gefinancierde project Catalina Sky Survey, stootten in de nacht van 15 februari op een object met een grootte van 1,90 op 3,50 meter dat rond onze planeet draait. “GROOT NIEUWS. De aarde heeft een nieuw gevangen/mogelijke minimaan met de naam 2020 CD3”, twitterde Wierzchos. Het zou kunnen gaan om een koolstofhoudende asteroïde.
Kacper Wierzchos@WierzchosKacper
BIG NEWS (thread 1/3). Earth has a new temporarily captured object/Possible mini-moon called 2020 CD3. On the night of Feb. 15, my Catalina Sky Survey teammate Teddy Pruyne and I found a 20th magnitude object. Here are the discovery images.
Voor de astronoom is de vondst belangrijk, want “het gaat om slechts de tweede asteroïde waarvan bekend is dat ze rond de aarde draait”, na 2006 RH120, een object dat ook dankzij het Catalina Sky Survey werd gevonden en tussen september 2006 en juni 2007 rond de aarde draaide. Het nieuwe object zou drie jaar geleden door de zwaartekracht van onze planeet zijn gevangen, zegt de astronoom.
Volgens het Centrum voor Planetoïden van het Smithsonian Astrophysical Observatory is er geen enkele link met een gekend artificieel object gevonden, waardoor het wel zeker een object moet zijn dat we met onze zwaartekracht hebben ingepalmd.
Weg in april
De baan van onze nieuwe maan is niet stabiel en 2020 CD3 is zich al aan het verwijderen uit het systeem aarde-maan. In april zou de maan alweer moeten verdwenen zijn, zegt Grigori Fedorets van de Queen’s University in Belfast tegenover het populair-wetenschappelijke magazine New Scientist.

Erich Von Daniken Explains Why the Ancient Aliens Never Left Us
Erich Von Daniken Explains Why the Ancient Aliens Never Left Us
COAST TO COAST AM -
Erich von Däniken updated his theory of ET contact with the ancient world, first explored in his bestselling book “Chariots of the Gods,” which has had a far-reaching influence on entertainment and science. His newest work,a sequel, called The Gods Never Left Us,talks about how with current scientific advancements in biotechnology and other fields, humanity is embarking on the same trajectory of interplanetary colonization that our ET ancestors did when they initially visited Earth.
He reminisced about his first visits to Nazca, Peru in 1960-61, when he saw the Nazca Lines, large ancient geoglyphs (the Nazca Spider is pictured) that take shape when seen from above. He proposed that these might have have been used as airstrips for the ETs.
Researchers at Tel Aviv University (TAU) have discovered a non-oxygen breathing animal. The unexpected finding changes one of science’s assumptions about the animal world.
A study on the finding was published on February 25 in PNAS by TAU researchers led by Prof. Dorothee Huchon of the School of Zoology at TAU’s Faculty of Life Sciences and Steinhardt Museum of Natural History.

The tiny, less than 10-celled parasite Henneguya salminicola lives in salmon muscle. As it evolved, the animal, which is a myxozoan relative of jellyfish and corals, gave up breathing and consuming oxygen to produce energy.
“Aerobic respiration was thought to be ubiquitous in animals, but now we confirmed that this is not the case,” Prof. Huchon explains. “Our discovery shows that evolution can go in strange directions. Aerobic respiration is a major source of energy, and yet we found an animal that gave up this critical pathway.”
Some other organisms like fungi, amoebas or ciliate lineages in anaerobic environments have lost the ability to breathe over time. The new study demonstrates that the same can happen to an animal — possibly because the parasite happens to live in an anaerobic environment.
Its genome was sequenced, along with those of other myxozoan fish parasites, as part of research supported by the U.S.-Israel Binational Science Foundation and conducted with Prof. Paulyn Cartwright of the University of Kansas, and Prof. Jerri Bartholomew and Dr. Stephen Atkinson of Oregon State University.
The parasite’s anaerobic nature was an accidental discovery. While assembling the Henneguya genome, Prof. Huchon found that it did not include a mitochondrial genome. The mitochondria is the powerhouse of the cell where oxygen is captured to make energy, so its absence indicated that the animal was not breathing oxygen.
Until the new discovery, there was debate regarding the possibility that organisms belonging to the animal kingdom could survive in anaerobic environments. The assumption that all animals are breathing oxygen was based, among other things, on the fact that animals are multicellular, highly developed organisms, which first appeared on Earth when oxygen levels rose.
“It’s not yet clear to us how the parasite generates energy,” Prof. Huchon says. “It may be drawing it from the surrounding fish cells, or it may have a different type of respiration such as oxygen-free breathing, which typically characterizes anaerobic non-animal organisms.”
According to Prof. Huchon, the discovery bears enormous significance for evolutionary research.
“It is generally thought that during evolution, organisms become more and more complex, and that simple single-celled or few-celled organisms are the ancestors of complex organisms,” she concludes. “But here, right before us, is an animal whose evolutionary process is the opposite. Living in an oxygen-free environment, it has shed unnecessary genes responsible for aerobic respiration and become an even simpler organism.”

Surviving the Toba Super-Eruption 74,000 Years Ago
Surviving the Toba Super-Eruption 74,000 Years Ago
New archaeological work supports the hypothesis that human populations were present in India by 80,000 years ago and that they survived one of the largest volcanic eruptions in the last two million years

In a study published in Nature Communications, researchers from the Department of Archeology at the Max Planck Institute for Human History, together with international partners, provide evidence that before and after the super eruption of the Toba volcano in India 74,000 years ago, users of Middle Paleolithic stone tools in India were present. The results support the assumption that Homo sapiens had reached South Asia even before the great waves of expansion of humans 60,000 years ago and that human population groups survived climatic and ecological changes there.
The Toba super eruption on the island of Sumatra, Indonesia, was one of the most violent volcanic events of the past two million years, about 5,000 times larger than the eruption of Mount St. Helen in the 1980s. This eruption occurred 74,000 years ago. Long-standing theories claim that it caused a “volcanic winter” of six to ten years that led to a 1,000-year cooling of the earth’s surface and major catastrophes, including the decimation of Asian hominin and mammalian populations and the almost complete eradication of our own Species. The few surviving Homo sapiens are said to have survived in Africa through the development of sophisticated social, symbolic and economic strategies. These strategies, so the assumption
Field research in southern India conducted by some of the authors of this study in 2007 questioned these theories and sparked major debates in archeology, genetics, and geosciences on the timing of modern humans’ spread beyond Africa and the effects of the Toba Super Eruption on climate and the environment. The current study continues this debate and provides evidence that Homo sapiens was present in Asia earlier and that the Toba supereruption was less apocalyptic than previously thought.
The Toba volcano eruption and human evolution
The current study reports on a unique, 80,000-year stratigraphic record from the archaeological site of Dhaba in the Middle Son Valley in northern India. Middle Paleolithic stone tools found in Dhaba provide strong evidence that there were human populations using tools in India before and after the Toba eruption 74,000 years ago. Professor JN Pal, senior researcher at the University of Allahabad in India, notes that “although the Toba ash in the Son Valley was first identified in the 1980s, we have had no relevant archaeological evidence so far, so the archaeological finds from Dhaba to fill a large gap in time. “

Professor Chris Clarkson of the University of Queensland, lead author of the study, added: “The stone tools used in Dhaba are similar to the tool sets used at the same time by Homo sapiens were used in Africa. The fact that these tool sets neither disappeared at the time of the Toba super outbreak, nor changed significantly shortly afterwards, indicates that the human population survived the so-called catastrophe and continued to create tools for changing their environment. “This new archaeological evidence underpins fossil fuels Evidence suggests that humans emigrated from Africa earlier than 60,000 years ago and spread across Eurasia, and it is in line with genetic evidence that humans crossed archaic hominin species like the Neanderthals more than 60,000 years ago ,
Stone tools from the Dhaba archaeological site. They were found in the layer that corresponds to the eruption of the Toba volcano. The molds typical of the Middle Paleolithic are shown here.
Although the Toba super eruption was a gigantic event, only a few climatologists and geoscientists continue to represent the previously formulated scenario of a “volcanic winter”. This suggests that the cooling of the earth was less serious and that the Toba eruption may not have caused the subsequent cold period. Recent archaeological research in Asia, including the findings reported by this study, does not support the belief that the hominin populations died out due to the Toba Super Outbreak.
Instead, archaeological evidence suggests that the human population in the region survived and coped with one of the most violent volcanic events in human history. This proves that small groups of hunters and gatherers were able to adapt to environmental changes. Nevertheless, the population groups that lived in the region around Dhaba more than 74,000 years ago do not seem to have contributed significantly to the gene pool of today’s population groups. It is likely that these hunters and gatherers faced a number of challenges for their long-term survival, including the dramatic environmental changes that followed over the millennia.

Mysterious Objects Flying in Japan, United States, Brazil and Mexico
Mysterious Objects Flying in Japan, United States, Brazil and Mexico
The topic of mysterious objects flying is one on which everyone has an opinion. From the strong believer to the condescending skeptic, everyone has deep rooted beliefs regarding the subject. Some believe UFOs are travelers from other planets or dimensions. Others believe them to be experimental military aircraft. Mystics are claiming it to be an angels. Some are meteorites.
Below strange flying objects caught on tape: What is it?
In my latest post from February 26, 2020, I wrote about the several rectangular shaped UFOs in wing formation flying at high speed through space and wondered whether these UFOs are man-made or extraterrestrial.
Now again such a mysterious craft has been captured on February 25, 2020 while another footage from November last year shows similar crafts flying in formation at an incredible speed through space.
I have no explanation for these strange objects, but perhaps someone can provide more clarity about these 'ghosts' UFOs.
Triangular UFO Over Texas Makes a Comeback After a Month
Triangular UFO Over Texas Makes a Comeback After a Month
Online alien hunters and conspiracy theorists had debates over a video showing a mysterious, shining triangular object over Houston, Texas. The footage was reportedly taken on New Year’s Day. Some suggested alien interference, while others believed the strange object had something to do with a secret military program.
Just recently, the UFO apparently made a comeback after a month of a similar sighting. A video, which reportedly captured in the sky over the city of Bogata by a motorist, shows three flashing lights moving in a geometric formation toward the cameraman before zooming off.
The sighting was first reported to Mutual UFO Network along with the clip of it. According to the report, the UFO was flying at the reporting witness at around 75mph and then it hovered over his car for a second and disappeared. YouTube conspiracy channel UFOmania posted the video on the video-sharing site.
While the footage’s authenticity has not been confirmed, some conspiracy theorists believe it shows an alien UFO. Others suggested the UFO could be a supersonic stealth surveillance plane of the US Air Force. A few also provided a mundane explanation saying that it was nothing more than a drone.
The latest video surfaced a month after the same clip showing what seems to be a large triangle UFO over Houston, Texas, on New Year’s Day. The bizarre object appeared to have three lights dancing in the dark sky and maintaining formation. It prompted conspiracy enthusiasts to offer alien and military-related theories as an explanation as well
Your daily horoscope: If it's your birthday today (or any other day), congratulations! You are very lucky. You were born into a universe of endless mystery and wonder — a vast and busy place where galaxies eat each other for fun and old suns explode into majestic rainbows of gas whenever they get too tired. (May we all hope for a similar end.)
Your home planet, Earth, is surrounded by billions of twinkling stars. A long time ago, ancient Earthlings connected the dots on a bunch of those stars, forming the 12 constellations of the zodiac. Many Earthlings still look to those constellations today, hoping to find relationship advice and existential guidance hidden in the cosmos. We cannot promise they will find it. But, if you look closely enough at any sign of the zodiac, you may see something even better: a wonder of the universe.
What astronomical oddities lurk in your sign? Follow the stars, and find out below.
Aries love competition, and the gas giant 30 Ari Bb — nestled about 146 light-years from Earth in the constellation Aries — is no exception. The massive exoplanet has not one, not two, but four suns in its sky. Take that, Tatooine!
How does one planet score four suns? In this case, 30 Ari Bb orbits a star in a binary system, a star system where two stars orbit around a common point. It turns out that this binary system orbits the same center of gravity as another binary system about 100 million miles away, making all four stars part of one big quadruple-star system. Astronomers have discovered only one other quadruple-star system like it in the universe, making 30 Ari Bb extremely rare… not that it's a competition or anything.
2. Taurus: a supernova graveyard
It's fortunate that Taurus and Cancer are such compatible signs, because there's a big, gassy crab nipping at the space bull's horns.
The Crab Nebula (aka Messier 1, or M1) is the remnant of a thousand-year-old supernova explosion — the violent death of star that can no longer support its own mass — located over the southern horn of Taurus. Beauty-loving bulls will be happy to know that such explosions create bright blasts of gas that can linger in the sky for tens of thousands of years or more; even now, the gas in M1 is expanding outward at about 3 million mph (4.8 million km/h).
3. Gemini: the great clown in the sky
Geminis are youthful, curious and fun. Add "horrific and menacing" to that list, and you've got a pretty apt description of the Clownface Nebula, a cackling gas cloud located in Gemini about 5,000 light-years from Earth.
Also known as the Eskimo Nebula, the Clownface Nebula is a planetary nebula (a bright cloud of ionized gas surrounding a dying star) made of two enormous, concentric rings. The rings are rimmed with furry filaments that stretch on for light-years, making the nebula resemble a tiny head wrapped in a parka hood — or a clown's creepy, painted visage. Laugh (or cry) if you like, but those fuzzy puffs of gas are so complex that scientists struggle to explain why they exist (much like real clowns).
4. Cancer: a world of diamond (or lava)
Cancers can be hard to get to know, and astronomers are having the same problem with the constellation's most famous exoplanet. Located just 40 light-years away, 55 Cancri E's is roughly twice as large as Earth and orbits its home star every 18 hours or so. That means the planet is superhot — thousands of degrees Fahrenheit on its night side alone — and probably has a pretty extreme composition. How extreme? Nobody really knows. Prior studies have hypothesized that the inscrutable planet is made completely of diamond, or else has only half an atmosphere, or maybe a surface perpetually oozing with lava. Alas, we'll just have to get closer to the planet before it opens up to us.
5. Leo: a runaway star
Stubborn like a true Leo, this runaway star in the lion constellation is literally shoving space aside as it tries to escape its neighborhood at 204,000 mph (329,000 km/h). The star, named CW Leonis and located about 310 light-years from Earth, is moving so fast, you can see it creating a bow shock (a wave of energy that pushes interstellar matter aside like the front of a boat cutting through water) in this satellite image taken in ultraviolet light. Where are you going, little star? Astronomers are too intimidated to ask, but they think CW Leonis has been charging forward for about 70,000 years now. It shows no signs of stopping.
6. Virgo: the biggest hat in the universe
It's not often that you see a Virgo making a scene ... or a black hole wearing a hat. Well, behold Messier 104, the Sombrero Galaxy. This quirky galaxy is a bright bulge of stars surrounded by a perfectly symmetrical ring of dust reminiscent of a sombrero's rim. This dust serves as an enormous nursery for baby stars (aww), but the real hotspot is at the sombrero's center, where a black hole with 1 billion times the mass of the sun constantly spills electromagnetic radiation into space. It's rare to see a Virgo spill anything without cleaning it up, but at least this galactic mess is 29 million light-years away.
7. Libra: two mirages of Earth
Two Earth-like worlds circling the distant star Gliese 581 could have the right stuff to sustain life. Or, they could be illusions. Gliese 581 is a red dwarf about 20 light-years into the constellation Libra, and may have as many as six planets spinning around it. Two of those potential planets — Gliese 581d and 581g — appear to sit in the star's habitable zone, or the Goldilocks sweet spot where a planet is neither too hot nor too cold to have liquid water. Worlds like these are rare, and some astronomers believe the pair of planets may not exist at all. According to one 2014 study, Gliese 581d and 581g might just be a mirage caused by flickering sunspots on their local star's surface.
So, these two worlds are either hugely exciting or hugely disappointing. Let's settle this like a Libra and just agree they're hugely something.
8. Scorpius: the nonstop nova
Passionate and persistent, a Scorpio does not give up on a relationship. Nor do the stars of U Scorpii, a stellar partnership where one star is endlessly giving — and the other star is dead.
U Scorpii is a recurrent nova, a rare class of double-star system where a white dwarf (the shriveled husk of a dead star) continuously pulls in matter from a neighboring star, then sneezes it out again in a brilliant blaze every few decades or so. The result is a constantly brightening and dimming twinkle in the sky that's easily mistaken for the birth of a new star but is actually just the perverse dance of a stellar corpse and its captive mate. U Scorpii is an especially active romance, lighting up the sky at least seven times in the past 150 years, most recently in 2010.
9. Sagittarius: the monster at the center of the galaxy
Sagittarians like to keep a tight circle of friends, and there's no tighter circle than the black hole at the center of the Milky Way — also known as Sagittarius A*.
Nestled deep in the hunter constellation, our supermassive black hole is sort of like the glue that holds the galaxy together. The region around the galactic center is about 1 billion times denser with stars than our corner of the Milky Way, and all that gas and dust makes Sagittarius A* impossible to see directly from Earth. However, scientists can see the structure's throbbing energy signature as it gulps down surrounding matter at near light speed. Sometimes it eats too fast and burps up gargantuan bubbles of radiation. Sometimes it plays with its food and returns it to the kitchen, pulling stars in just close enough to transform their composition and then sending them on their way. Like many Sagittarians, the hole is fickle and uncompromising — and we'd be very sad without its company.
If you're expecting order from a constellation that's half-goat and half-mermaid, prepare to be disappointed. Consider Capricornus's most handsome galaxy group, HCG 87. The cluster of three gravitationally bound galaxies looks nice and tidy in family portraits like this one, but astronomers know that the familial harmony is only temporary. Within the next billion years, the three figures will rip each other to bits in a chaotic pileup, turning the galactic trio into one giant mess of stars. After a billion years staring at the same galaxies every day, there could be worse outcomes.
11. Aquarius: the Eye of God/Sauron
Aquarians are an observant lot. A crafty Aquarian could probably look at this photo of the Helix Nebula, for example, and see an enormous, terrifying eye staring into the depths of their souls. (Don't feel bad if you don't see it.)
The Helix Nebula (located 700 light-years away, in Aquarius) has been compared to the Eye of Sauron and the Eye of God. It's actually just a dead star cloaked in dust, and it takes on a fearsome pupil shape thanks to the star's infrared glow. It's spooky, though not nearly as spooky as the Skull and Crossbones Nebula lurking in the Puppis constellation. (Are you observant enough to guess what that one looks like?)
12. Pisces: a perfect whirlpool
A romantic Pisces will probably try to woo you with a line about how you are made of stardust. That's very nice (nothing is sexier to an astronomy fan than dust), but for a more rewarding cosmic encounter, we suggest turning your attention to the Phantom Galaxy — aka M74 — nestled 32 million away in the constellation Pisces.
The Phantom Galaxy has been described as the perfect spiral galaxy, but really it's just the perfect view of one. From Earth, astronomers can see the galaxy's golden center and graceful spiral arms head-on, offering an unobstructed look at the galaxy's 100 billion stars. It's a gorgeous sight ... but not nearly as gorgeous as you. ;)
But me being me, my mind went straight to Mars. I have long been aware of science fiction's vision of Earth receiving space souvenirs that carry organisms that might be dangerous to Earth's fragile biosphere — that's me, and you, too! Such arrivals could be accidental, or they could be purposeful.
Meanwhile, President Donald Trump's budget request for NASA supports the development of the Mars sample return mission, a robotic program that would haul back the goods from the Red Planet.
What if such samples turned out to be dangerous, and contagiously so? Are there some Mars-oriented lessons to be learned from COVID-19 and other major infectious diseases?
In 1973, Carl Sagan published "The Cosmic Connection — An Extraterrestrial Perspective," offering this view of Martian pathogens:
"Precisely because Mars is an environment of great potential biological interest, it is possible that on Mars there are pathogens, organisms which, if transported to the terrestrial environment, might do enormous biological damage — a Martian plague, the twist in the plot of H. G. Wells' War of the Worlds, but in reverse. This is an extremely grave point. On the one hand, we can argue that Martian organisms cannot cause any serious problems to terrestrial organisms, because there has been no biological contact for 4.5 billion years between Martian and terrestrial organisms. On the other hand, we can argue equally well that terrestrial organisms have evolved no defenses against potential Martian pathogens, precisely because there has been no such contact for 4.5 billion years. The chance of such an infection may be very small, but the hazards, if it occurs, are certainly very high."
Concern and ignorance
What might happen if such an infection does occur? "I think that it might be instructive to consider the climate of concern that accompanies the current situation with coronavirus," John Rummel, a senior scientist at the SETI Institute in California and NASA's planetary protection officer from 1986 to 1993 and 1997 to 2006, told Space.com.
For example, the diagnostic tests available for coronavirus right now aren't perfectly accurate, and it can take more than a week after infection for symptoms to develop. And while a terrestrial infection might be limited by the change of seasons, that wouldn't necessarily hold true for a foreign disease vector.
"I think that the challenge for a Mars sample return activity is to be open about precautions taken in the face of ignorance," Rummel said, "which is what we have … when we discuss life on Mars."
Schools of thought
Scientists have various schools of thought on hauling Mars samples back to our planet, Rummel said. But the planned, precautionary approach, based on strict containment and testing for life and biohazards, is compatible with the potential to discover life in a sample, or elsewhere on Mars by other means, as it would still allow for a sample to be returned.
"If one finds life in the sample, one has a good chance of being able to study it in containment," Rummel said. "The downside of this approach is that it is more expensive [in terms of establishing the containment facility], up-front, than ignoring life on Mars."
Rummel said that, if something like the coronavirus situation pops up, then any other containment facility may not be available in a timely way, and may not be able to meet the cleanliness requirements that will ensure that any organisms discovered in the sample came from Mars, and not from Earth after the sample arrives.
Precautionary steps
Is the emergence of a new epidemic here on our planet a cue about taking precautionary steps regarding planetary protection?
Catharine Conley was NASA's planetary protection officer from 2006 until November 2017. "As with historical infectious disease epidemics, the coronavirus that's spreading currently is another example of why it's so important to understand the consequences of interacting with environments humans rarely contact and then distributing widely whatever [they] picked up," she said.
"In the case of Mars exploration, it's most likely that Earth organisms transported to Mars could cause problems for future inhabitants," Conley said. "If Mars life exists and is brought to Earth, it's more likely to cause effects on the environment, like the algae recently found to be warming the ice in Greenland, than that it would be a virulent human pathogen."
However, if Mars life is related to terrestrial life, Conley said, "that makes it much harder to distinguish from Earth contamination — and also, just like diseases that jump species, more likely to affect us, too."
The magnetic field in one zone on Mars is about 10 times stronger than scientists expected, and it's changing rapidly.
New data gathered from NASA's InSight lander, which has been on the Red Planet for a little over a year now, shows that the planet's magnetic field fluctuates rapidly. InSight is the first landing mission to carry a magnetic sensor, which allows it to measure these fields from up close.
"The ground-level data give us a much more sensitive picture of magnetization over smaller areas, and where it's coming from," lead author Catherine Johnson, a professor at the University of British Columbia and senior scientist at the Planetary Science Institute, said in a statement. "In addition to showing that the magnetic field at the landing site was ten times stronger than the satellites anticipated, the data implied it was coming from nearby sources."
InSight is designed to collect data that helps scientists to reveal more about how rocky planets form by looking at the planet’s interior. Before the lander touched down in November 2018, magnetic fields were measured by satellite and often averaged a distance from the epicenter that was more than 90 miles across.
Billions of years ago, Mars used to have a global magnetic field, but it shut down for reasons that are still unknown, about 4 billion years ago, leaving the atmosphere unshielded to radiation and causing it to bleed over time into space. Any residual fields are likely coming from older rocks buried several feet or miles underneath the planet's surface, these new results from InSight suggest. The team plans to continue to study Mars using InSight to better identify what different types of rocks there are and where they are.
These observations from InSight also showed that the sun influences the Martian magnetic field. The sun sends out charged particles across the solar system in a phenomenon known as the solar wind. These particles carry an interplanetary magnetic field (IMF) that can cause fluctuations in the local magnetic field when it hits the Martian atmosphere. That's because Mars, unlike Earth, has no global magnetic field to act as a buffer against these solar storms.
There is also some strange data that InSight has collected, revealing things like fluctuations in the magnetic field around midnight, which are likely related to how the solar wind and IMF move around Mars, inducing electrical currents and magnetic fields on the planet. Future observations will help to inform researchers exactly why this is happening, with InSight providing data from the surface at the same time that NASA's Mars Atmosphere and Volatile Evolution (MAVEN) examines the atmosphere above the landing site.
"Because all of our previous observations of Mars have been from the top of its atmosphere or even higher altitudes, we didn't know whether disturbances in solar wind would propagate to the surface," said Johnson. "That's an important thing to understand for future astronaut missions to Mars."
Earth has picked up a tiny asteroid hitchhiker, according to astronomical observations made this month.
Called 2020 CD3, the space rock was captured from deep space by our planet’s gravity, making it only the second temporary “mini-moon” that astronomers have spotted orbiting Earth.
Kacper Wierzchos@WierzchosKacper
BIG NEWS (thread 1/3). Earth has a new temporarily captured object/Possible mini-moon called 2020 CD3. On the night of Feb. 15, my Catalina Sky Survey teammate Teddy Pruyne and I found a 20th magnitude object. Here are the discovery images.
The asteroid was discovered on February 15 by Theodore Pruyne and Kacper Wierzchos, a pair of astronomers based at the University of Arizona. On Tuesday, Wierzchos described the find as “a big deal” on Twitter and revealed that the object appears to have been tugged into orbit around Earth about three years ago.
The newly identified asteroid is only a few meters wide, but Pruyne and Wierzchos were able to detect it thanks to the NASA-funded Catalina Sky Survey (CSS), which is specially designed to flag and track near-Earth objects (NEOs). CSS was also the facility that spotted the first captured asteroid, called 2006 RH120, which got sucked into Earth orbit in 2006 and was ejected back out into heliocentric orbit in 2007.
The International Astronomical Union’s Minor Planet Center, which manages the official catalogue of small celestial bodies, confirmed that 2020 CD3 is a temporary satellite on Tuesday.
Though only two of these captured asteroids have been imaged so far, there are likely more of them out there that are simply too faint and small to be detected. A 2012 study in the journalIcarus predicted that, statistically, there is at least one meter-scale asteroid orbiting Earth at any particular time.
For more than a century, skywatchers have claimed to have spotted these temporary satellites but CSS is the only facility so far that has captured definitive observations of them. The introduction of next-generation telescopes, such as the Vera C. Rubin Observatory in Chile, will likely lead to many more detections of these orbital stowaways.
