Wetenschappers ontdekken fossiele ‘vliegende draak’ in Chileense woestijn
Wetenschappers ontdekken fossiele ‘vliegende draak’ in Chileense woestijn
In de Chileense Atacamawoestijn hebben archeologen fossiele resten ontdekt van een prehistorisch dier dat zich laat omschrijven als ‘een vliegende draak’. Zo'n 200 tot 150 miljoen jaar geleden vloog de pterosaurus, voorzien van een lange staart, vleugels en scherpe uitstekende tanden, er zijn rondjes.
David van der Heeden
Het vliegende reptiel behoort tot een groep die al eerder op het noordelijk halfrond werd ontdekt. Naar nu blijkt heeft het zo uit Jurassic Park weggevlogen monster ook in Zuid-Amerika zijn vleugels uitgeslagen. De versteende botten van het dier werden al in 2009 ontdekt door de directeur van het natuurhistorisch museum van de Atacamawoestijn en werden jarenlang onderzocht door wetenschappers van de universiteit van Chili.
De ontdekking vormt het eerste bewijs dat de pterosauriërs - de eerste gewervelde dieren die konden vliegen, voorlopers van de Pterodactylus - ook op het zuidelijk halfrond voorkwamen. “Dit toont aan dat de dieren in deze groep wijder verspreid waren dan we tot nu toe wisten”, zegt onderzoeksleider Jhonatan Alarcon. De bevindingen van het team zijn gepubliceerd in wetenschapsjournaal Acta Palaeontologica Polonica.
Het is overigens niet zo dat deze Rhamphorhynchus - vernoemd naar de groep waartoe de voorwereldlijke fladderaar behoorde - ongeschonden uit de grond werd gehaald. De deskundigen moesten het doen met een stuk bot uit de voorpoot, een mogelijke ruggenwervel en een gedeeltelijk vleugelkootje. Genoeg bewijs echter om de ‘koning van de lucht’ aan Zuid-Amerika te linken.
Wetenschappers denken dat de zuidelijke landmassa’s tijdens de Jura-periode aan elkaar zaten. Een supercontinent dat Gondwana wordt genoemd. Mogelijk de reden waarom andere leden van de dierengroep ook op Cuba zijn gevonden. “Waarschijnlijk vlogen ze van noord naar zuid”, aldus Alarcon. “Misschien zijn ze hier ooit aangekomen en gebleven, we weten het niet.”
Hoe groot het fabelachtige wezen precies was, schrijven de experts niet. Er zijn aanwijzingen dat het om een dier van ‘gemiddelde grootte’ ging. Een volwassen exemplaar. Sommige familieleden konden echter een vleugelspanwijdte van bijna twee meter bereiken, zo is bekend. Van Rhamphorhynchus zijn meer volledige skeletten gevonden dan van welk andere pterosauriërs maar ook. Hij had een spitse kop, zwemvliezen en at vis.
De Atacamawoestijn is een immens groot gebied, dat ooit onder het water van de Stille Oceaan schuilging. Nu oogt het als een maanlandschap. Sommige delen van de woestenij hebben al tientallen jaren geen regen gezien. Er zijn alleen stenen en zand te vinden. En fossielen voor wie zijn schep in de grond steekt. Het gebied staat bekend om zijn fossiele vondsten. Veel ervan worden net onder het dorre oppervlak gevonden.
New photos taken of the incredibly unique Kleopatra asteroid that is shaped like a dog bone have revealed very interesting details. Kleopatra is located in the Asteroid Belt that’s located between Mars and Jupiter. It has two lobe shapes on either end with a long “neck” in between them – basically it looks like a dog bone. Additionally, it has two tiny moons that have been named AlexHelios and CleoSelene after the Egyptian Pharaoh Cleopatra’s kids.
Even though Kleopatra was discovered back in 1880, scientists have only known about its size as well as the moons for approximately twenty years, but the new photos showing different angles have helped them even more, like calculating the its measurements, the moons’ orbits, and how they were formed. They did this with observations from the SPHERE instrument on the European Southern Observatory’s Very Large Telescope in Chile.
Kleopatra
They concluded that Kleopatra measures about 270 kilometers in length (168 miles); that one of the lobe shapes is larger than the other; and that its “neck” is actually quite thick. A different team of researchers then calculated the orbits of the two moons in order to figure out the mass of the asteroid. They determined that Kleopatra’s mass is 2.97 x 1018 kilograms which is quite a bit less than previous estimates that had it at 4.64 x 1018 kilograms.
The researchers were then able to calculate the density and based on the assumption that the asteroid is rich in metals, the number was rather low. Since Kleopatra has low density, it would indicate that it is quite porous with a lot of loose rock that is hardly secure on the asteroid. This also suggests that the “rubble pile” may have happened when a bunch of debris was thrown off of a parent body when a large impact occurred. Furthermore, if there is material that is being ejected from the asteroid, that could explain how the two moons were formed.
Unfortunately for Kleopatra, its very fast rotation could make it fall apart pretty easily if it is porous. In fact, it rotates once every 5.4 hours and if it were to pick up even a slight amount of speed, it would tear apart.
Kleopatra
But for now, it is quickly rotating through space and the new images have certainly helped with learning more about this very odd-looking “dog bone” asteroid. Astronomer Franck Marchis from the SETI Institute and the Laboratoire d’Astrophysique de Marseille in France said it best when he stated, “Kleopatra is truly a unique body in our Solar System.” More pictures of the Kleopatra asteroid can be seen here.
These eleven images are of the asteroid Kleopatra, viewed at different angles as it rotates. The images were taken at different times between 2017 and 2019 with the Spectro-Polarimetric High-contrast Exoplanet REsearch (SPHERE) instrument on ESO’s VLT.
Kleopatra orbits the Sun in the Asteroid Belt between Mars and Jupiter. Astronomers have called it a “dog-bone asteroid” ever since radar observations around 20 years ago revealed it has two lobes connected by a thick “neck”.

The asteroids Ryugu and Bennu which orbit between Earth and Mars formed after a much larger rock was split apart, scientists have claimed.
Mathematical modelling suggests the pair - measuring 3,280-foot and 1,610-foot in diameter - formed after two centres of gravity were created.
But rock pulled from both will need to be tested to confirm the theory.
Samples from Ryugu are already onboard Japan's Hayabusa2 spacecraft and expected to touchdown on Earth in late 2020.
And NASA's OSIRIS-REx is scheduled to land on its suspected-sister by October 20, to collect further samples which will also be flown to Earth.
Mathematical modelling revealed Ryugu (left) and Bennu (right) may have formed from a larger asteroid that broke apart
The model showed after an asteroid shattered its pieces came together at two points
It was based on observations of asteroids in the Mars-Jupiter belt, where Bennu and Ryugu may have originated
Astronomers at the University of Arizona and Laboratoire Lagrange, Ivory Coast, modelled collisions in the Mars-Jupiter asteroid belt before making the proposal.
Their study, published in Nature Communications, showed fragments are ejected but then re-accumulate into a spinning-top shape - like that of both asteroids.
They also noted a difference in hydration between the possible-siblings, but said this did not discount the proposed relationship.
The team hopes to be able to measure the composition and age of formation of the samples from both asteroids to confirm their theory.
OSIRIS-REx has beamed images of Bennu's rocky surface back to Earth, revealing the barren lunar surface.
The pictures show its chosen landing site - dubbed 'Nightingale' - which is located in a crater high up the asteroids northern hemisphere.
The spacecraft will cut chunks 0.8 inches in diameter from the asteroid before beginning the journey home.
NASA has sent pictures of Bennu back to Earth. The image above shows the proposed landing site on the asteroid for its spacecraft OSIRIS-REx
OSIRIS-REx will collect small (less than 0.8 inches in diameter) rocks from the surface before beginning the journey back to Earth.
(Artists impression)
Hayabusa2, not to be outdone, sent images of Ryugu's lunar-surface back to Earth in February.
Its pictures revealed reddening in some of the rocks, leading scientists at the University of Tokyo to conclude that it once passed much closer to the sun.
'Immediately after touchdown, Hayabusa2’s thrusters disturbed dark, fine grains that originate from the redder materials,' wrote planetary scientist Tomokatsu Morota of the University of Tokyo and colleagues in their paper,
'The stratigraphic relationship between identified craters and the redder material indicates that surface reddening occurred over a short period of time.'
'We suggest that Ryugu previously experienced an orbital excursion near the Sun.'
Japan's Hayabusa2 spacecraft has captured this picture of Ryugu's surface. It revealed reddened rocks, which suggests at one point the asteroid may have passed near the Sun
Why are Rubble Pile Asteroids Shaped Like Diamonds?
Why are Rubble Pile Asteroids Shaped Like Diamonds?
Scientists are fortunate enough to have detailed, close-up views of the near-Earth asteroids Bennu and Ryugu. Both asteroids have a diamond shape, for some reason. Why? Up until now, it’s been a puzzle.
Now a team of scientists has tackled the question and may have come up with the answer.
Asteroids are an ongoing target of study for scientists. They’re remnants from the primordial Solar System, material that wasn’t swept up in planet formation. Most of them are way out in the asteroid belt, where they’re difficult to study.
But some of them have escaped the belt and come close to Earth. These near-Earth asteroids give scientists their best chance to study them. Spacecraft have been sent to both Ryugu and Bennu to collect samples and return them to Earth. While there, both the Japanese spacecraft Hayabusa 2, which visited Ryugu, and NASA’s OSIRIS-REx, which visited Bennu, studied their asteroid targets intensely, including gathering detailed images.
Both are rubble-pile asteroids, which means that they’re made up of chunks of smaller material bound together by gravity, and both are diamond-shaped. Both also rotate rapidly.

A group of researchers from the Okinawa Institute of Science and Technology (OIST) and Rutgers University have published a paper explaining the asteroids’ diamond shape. The paper is titled “Bennu and Ryugu: diamonds in the sky.” It’s published in the journal Granular Matter. The lead author is Dr. Tapan Sabuwala from OIST.
The fact that they’re just loosely held-together, smaller pieces of material means that they’re like granular matter, rather than larger, monolithic pieces of rock. So to study them and their diamond shape, the team of scientists made use of granular physics modelling. In this case, a model of how sand grains flow helped explain the diamond shape.
This isn’t the first attempt at using models to understand the asteroids’ shapes. Those models relied on rotation to explain the shape, but the models didn’t hold up to testing.
“Previous models have attributed these diamond shapes to the forces caused by the rotation, which resulted in material being driven from the poles to the equator,” said paper lead author Dr. Tapan Sabuwala. “But when the asteroids were simulated using these models, the shape was flattened or asymmetric rather than diamond, so we knew something wasn’t right,” explained Dr. Sabuwala in a press release.
The press release accompanying the study used sand flowing through a funnel as an example. As sand is poured in, it forms a conical shape. Of course, there’s much more going on at an asteroid than there is on a simple pile of sand. The gravitational forces are much different. “We had to factor this into our model, alongside the fact that the asteroid’s rotation also plays a significant role,” Dr, Sabuwala said.

According to the paper, centrifugal force played a large role in Bennu’s and Ryugu’s shape. It’s weaker near the asteroids’ poles, so more material accumulates there. That gives the asteroids their distinct appearance. “We show that this accumulation results in increased elevations at the poles, while centrifugal migration increases elevations at the equator. Without this accumulation, poles lack the elevated poles that are evident on Ryugu and Bennu,” the authors write in their paper.
This work deviates from previous models in another important way. It shows that the asteroids didn’t form as a different shape then gradually become diamond-shaped. Instead, the diamond shape formed as the asteroid formed and as material accumulated. The asteroids’ shape only changed minimally over time.
“The model relies on the principle of a critical angle of repose assumed by falling grains deposited on spinning, rubble-pile asteroids. Since the model is driven by deposition, our results suggest first that Bennu and Ryugu acquired their characteristic shapes at early times and second that subsequent reshaping by other effects … may be minimal,” they write in the paper’s summary.
Next, the researchers would like to look at other rubble-pile asteroids that rotate more slowly. Those types of asteroids should form a more spheroidal shape since the centrifugal force is weaker. When they reduced the rotation rate in their modelling, that’s exactly what resulted.
When the researchers reduced the rotation rate in the models, it reduced the centrifugal force, resulting in a more spheroidal shape. Image Credit: Sabuwala et al 2021.
“We have used simple concepts of how grains flow to explain how these asteroids assumed their curious shapes,” said co-author Professor Chakraborty of OIST. “That simple ideas can illuminate complex problems is, to us, perhaps the most delightful aspect of this work.”
Ancient Egyptian civilization is shrouded in mystery. Scientists still struggle to understand how Egyptians placed millions of hewn stones weighing at least two tons on top of one another. Supporters of conspiracy theories claim that those structures were not built by humans but rather by extraterrestrial civilizations.
Scott C Waring, who tirelessly searches for signs of extraterrestrial life, claims to have discovered the head of an ancient royal in stone on Mars. According to the self-proclaimed ufologist, he stumbled upon the finding while examining images of the Red Planet online, something UFO hunters often do.
Waring alleges that one of the stones looks like a male head wearing a helmet. [It is] "a show of the status and warrior attributes of those individuals", the ufologist wrote in a statement on his blog.
Waring suggested that the shape and size of the purported helmet are similar to the one worn by Pharaoh Thutmose I.
Scott C Waring provided no explanation as to how the Egyptian ruler might have ended up on the Red Planet, especially as back in April his mummy and sarcophagus were moved to the National Museum of Egyptian Civilization.

Bright UFO ball like reddish smoke with single trail turning into 2 trails – Dover, DE 10-Sep-2021
This strange UFO phenomenon was filmed over Dover, the capital city of Delaware in United States on 10th September 2021.
Witness report:
A bright ball like reddish smoke with single trail turning into 2 trails It was around 7:15 pm when my wife and I started to take a walk in our neighborhood. The sun was setting in the west with pink clouds in the distance. There was still blue sky left. That’s when I noticed what looked like a dark pink cloud by itself and out of place. I stopped to look at it and asked my wife if she saw it moving. She said yes. Then the cloud started to move slowly towards us and with a tail like a comet. Then it seem to turn away from us with 2 tails. It finally went from reddish to black then went into cloud cover and it was gone.

Wreckage from mysterious UFO crashes could unlock alien secrets, experts say
Debris from 70 years of alleged UFO crashes has been studied in a new state-of-the-art lab machine at Stanford University, California - and many were hoping some mysteries could be solved
Physical debris from two allegedUFOcrash sites over the past 70 years has been examined in a lab, it has been confirmed.
A new state-of-the-art machine has enabled scientists at Stanford University, California, to study in-depth was what collected.
Metal debris from UFO cases dating as far back as 1947 has been investigated. It obtained through on field research of supposed crashes in Colombia and Argentina.
The new “multi-parameter ion beam imager” gives scientists the chance to look at the atomic structure of a selected material.
Science News reports that Stanford microbiologist Dr Garry Nolan is using the machine to create a revolutionary three-dimensional image.
Debris was obtained through on-field research of alleged UFO crashes in Colombia and Argentina

When Dr Nolan placed some of the fragments in the vacuum chamber of his instrument, he was astonished to find their composition unlike any other metal.
He said: “If you’re talking about an advanced material from an advanced civilisation, you’re talking about something that I’ll just call an ultra-material.
Scientists discovered that material found was manufactured and not natural

“It’s something which has properties where somebody is putting it together again at an atomic scale.
“We’re building our world with 80 elements, somebody else is building the world with 253 different isotopes.”
The scientists discovered that this material was manufactured and not natural.
It comes as a new study claimed aliens could be powering their societies by harvesting energy from black holes.
Extraterrestrials could, theoretically, use a hypothetical megastructure called a Dyson sphere, which would encircle a star with a tight formation of orbiting platforms in order to capture starlight and produce power, it has been suggested.
Astronomer Tiger Yu-Yang Hsiao, of National Tsing Hua University in Taiwan, looked at whether one of these could actually be built around a black hole instead of a star in their paper.
Paper 'A Dyson sphere around a black hole' was published in July in the journal Monthly Notices of the Royal Astronomical Society.
In the study they looked at the possible emission from the accretion disk around a black hole, its corona, and even relativistic jets emitted by the black hole.
"Usually, accretion disks can provide 10,000 and even more times the energy you would get from a star like the Sun," Hsiao told IFLScience.
"So instead of hunting 10,000 stars like our Sun, we can just find one black hole and build a Dyson sphere around it and it would be much more efficient."
NASA’s Perseverance Rover Collects Puzzle Pieces of Mars’ History
NASA’s Perseverance Rover Collects Puzzle Pieces of Mars’ History
Two holes are visible in the rock, nicknamed “Rochette,” from which NASA’s Perseverance rover obtained its first core samples. The rover drilled the hole on the left, called “Montagnac,” on Sept. 7, and the hole on the right, known as “Montdenier,” on Sept. 1. Below it is a round spot the rover abraded.

NASA’s Perseverance Mars rover successfully collected its first pair of rock samples, and scientists already are gaining new insights into the region. After collecting its first sample, named “Montdenier,” Sept. 6, the team collected a second, “Montagnac,” from the same rock Sept. 8.
Analysis of the rocks from which the Montdenier and Montagnac samples were taken and from the rover’s previous sampling attempt may help the science team piece together the timeline of the area’s past, which was marked by volcanic activity and periods of persistent water.
“It looks like our first rocks reveal a potentially habitable sustained environment,” said Ken Farley of Caltech, project scientist for the mission, which is led by NASA’s Jet Propulsion Laboratory (JPL) in Southern California. “It’s a big deal that the water was there a long time.”
The rock that provided the mission’s first core samples is basaltic in composition and may be the product of lava flows. The presence of crystalline minerals in volcanic rocks is especially helpful in radiometric dating. The volcanic origin of the rock could help scientists accurately date when it formed. Each sample can serve as part of a larger chronological puzzle; put them in the right order, and scientists have a timeline of the most important events in the crater’s history. Some of those events include the formation of Jezero Crater, the emergence and disappearance of Jezero’s lake, and changes to the planet’s climate in the ancient past.
What’s more, salts have been spied within these rocks. These salts may have formed when groundwater flowed through and altered the original minerals in the rock, or more likely when liquid water evaporated, leaving the salts. The salt minerals in these first two rock cores may also have trapped tiny bubbles of ancient Martian water. If present, they could serve as microscopic time capsules, offering clues about the ancient climate and habitability of Mars. Salt minerals are also well-known on Earth for their ability to preserve signs of ancient life.
The Perseverance science team already knew a lake once filled the crater; for how long has been more uncertain. The scientists couldn’t dismiss the possibility that Jezero’s lake was a “flash in the pan”: floodwaters could have rapidly filled the impact crater and dried up in the space of 50 years, for example.
But the level of alteration that scientists see in the rock that provided the core samples – as well as in the rock the team targeted on their first sample-acquisition attempt – suggests that groundwater was present for a long time.
This groundwater could have been related to the lake that was once in Jezero, or it could have traveled through the rocks long after the lake had dried up. Though scientists still can’t say whether any of the water that altered these rocks was present for tens of thousands or for millions of years, they feel more certain that it was there for long enough to make the area more welcoming to microscopic life in the past.
“These samples have high value for future laboratory analysis back on Earth,” said Mitch Schulte of NASA Headquarters, the mission’s program scientist. “One day, we may be able to work out the sequence and timing of the environmental conditions that this rock’s minerals represent. This will help answer the big-picture science question of the history and stability of liquid water on Mars.”
Next Stop, ‘South Séítah’
Perseverance is currently searching the crater floor for samples that can be brought back to Earth to answer profound questions about Mars’ history. Promising samples are sealed in titanium tubes the rover carries in its chassis, where they’ll be stored until Perseverance drops them to be retrieved by a future mission. Perseverance will likely create multiple “depots” later in the mission, where it will drop off samples for a future mission to bring to Earth. Having one or more depots increases the likelihood that especially valuable samples will be accessible for retrieval to Earth.
Perseverance’s next likely sample site is just 656 feet (200 meters) away in “South Séítah,” a series of ridges covered by sand dunes, boulders, and rock shards that Farley likens to “broken dinner plates.”
The rover’s recent drill sample represents what is likely one of the youngest rock layers that can be found on Jezero Crater’s floor. South Séítah, on the other hand, is likely older, and will provide the science team a better timeline to understand events that shaped the crater floor, including its lake.
By the start of October, all Mars missions will be standing down from commanding their spacecraft for several weeks, a protective measure during a period called Mars solar conjunction. Perseverance isn’t likely to drill in South Séítah until sometime after that period.
More About Perseverance
A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith --broken rock and dust.
Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and bring them to Earth for in-depth analysis.
The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.
JPL, which is managed for NASA by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.
Guarded by aliens? The last time humans stepped on the moon
Guarded by aliens? The last time humans stepped on the moon
The UFO community found numerous anomalies after investigating thousands of official photos captured during the Apollo 17 moon mission.
Apollo 17 was the last official mission of the American ‘Apollo’ program that brought the first astronauts to the Moon in 1972.
During the 12-day lunar mission, the crew captured more than 8,400 photos of the lunar surface that are now available on NASA’s website .
Years after the photos became available, UFO hunters discovered curious objects in some of the images that resemble spaceships, origins unknown.
In fact, there are those who believe that the anomalies are simply reflections or lens flares, but the growing evidence tends to disprove these theories easily.
Apollo 17 remains the most recent manned mission to the Moon, with no other astronauts having set foot there since 1972. Could this be just a coincidence?
The constant number of days spent both in space and on the Moon, as well as the fact that no other manned missions have been conducted since then, raises many questions.
Is it possible that the Apollo 17 astronauts encountered an alien moon base? Were they found by UFOs or crafts from another world? If so, did anyone restrict or deny human access to the lunar surface?
Why would the Apollo 17 mission gather such a large volume of samples, take so many photographs, and never investigate its findings further again?
Is the natural satellite that orbits our planet so desolate and unimportant that no further missions are necessary?
While it is still difficult to prove that the astronauts were intercepted by aliens, the reality of the UFOs present in many stages of the Apollo 17 mission is a clear indicator (for some of us at least) that NASA could be in favor of a Covert pact with beings from another world ..
White Dwarfs can Continue Burning Hydrogen, Even After They’re Dead
White Dwarfs can Continue Burning Hydrogen, Even After They’re Dead
White dwarfs are supposed to be dead remnants of stars, doomed to simply fade away into the background. But new observations show that some are able to maintain some semblance of life by wrapping themselves in a layer of fusing hydrogen.
White dwarfs are the dense leftover cores of sunlike stars. They are exposed to the universe when stars build up too much carbon and oxygen in their centers. They then tear themselves apart in a slow, agonizing process that eventually creates a planetary nebula. With all the outer layers stripped, the core remains – a white dwarf.
White dwarfs are inert. They don’t have enough mass to ignite nuclear fusion of their carbon and oxygen, and so they just sit there, slowly radiating away their heat for eons upon eons.
But new research is challenging that simple story.
“We have found the first observational evidence that white dwarfs can still undergo stable thermonuclear activity,” explained Jianxing Chen of the Alma Mater Studiorum Università di Bologna and the Italian National Institute for Astrophysics, who led this research. “This was quite a surprise, as it is at odds with what is commonly believed.”
The research team led by Chen compared two globular clusters, M3 and M13, with the Hubble Space Telescope. They especially focused on near-ultraviolet wavelengths, which allowed them to compare more than 700 white dwarfs inside the two clusters.
They found that the white dwarfs in M3 were pretty standard, but that M13 had two different populations: one set of normal white dwarfs, and another that were enveloped by an outer layer of hydrogen.
Combining the results with computer simulations, Chen and his colleagues determined that around 70% of the white dwarfs in M13 had so much hydrogen surrounding them that the shells were actively undergoing fusion. That fusion is able to keep the white dwarfs warmer for far longer than astronomers had previously thought possible.
Astronomers use established cooling time relationships to connect the temperature of a white dwarf to its age, which helps them better understand their origins and environment. The new research makes that relationship a little murkier.
“Our discovery challenges the definition of white dwarfs as we consider a new perspective on the way in which stars get old,” added Francesco Ferraro of the Alma Mater Studiorum Università di Bologna and the Italian National Institute for Astrophysics, who coordinated the study. “We are now investigating other clusters similar to M13 to further constrain the conditions which drive stars to maintain the thin hydrogen envelope which allows them to age slowly.”

UFOs & UAPs: The Situation Has Changed! Avi Loeb and Harvard’s Galileo Project
UFOs & UAPs: The Situation Has Changed! Avi Loeb and Harvard’s Galileo Project
! In 2017, the world for the first time observed an interstellar object, called ‘Oumuamua, that was briefly visiting our Solar system. Based on astronomical observations, ‘Oumuamua turned out to have highly anomalous properties that defy well-understood natural explanations. We can only speculate whether ‘Oumuamua may be explained by never seen before natural explanations, or perhaps being an extraterrestrial technological object, similar to a very thin light-sail or communication dish, which fits the astronomical data rather well.
After the release of the Pentagon Office of the Director of National Intelligence report on Unidentified Aerial Phenomena (UAP), the scientific community now needs the determination to systematically, scientifically & transparently look for potential evidence of extraterrestrial technological equipment. The impact of any discovery of extraterrestrial technology on science & on our entire worldview would be enormous. Given the recently discovered abundance of Earth-Sun systems, the Galileo Project is dedicated to the proposition that humans can no longer ignore the possible existence of Extraterrestrial Technological Civilizations (ETCs), & that science should not dogmatically reject potential extraterrestrial explanations because of social stigma or cultural preferences, factors which are not conducive to the scientific method of unbiased, empirical inquiry. We now must look through new telescopes’, both literally & figuratively. The Galileo Project aims to identify the nature of UAP and ‘Oumuamua-like interstellar objects using the standard scientific method based on a transparent analysis of open scientific data to be collected using optimized instruments.
Professor Paul Davies, an astrobiologist, cosmologist and director of the Beyond Center for Fundamental Concepts in Science at Arizona State University says that for life to exist outside of Earth, there must be a high number of microbes and several microscopic agents in space. He believes that if there is extra-terrestrial life with these agents on their planet, then there might also be viruses too. Mr Davies says that viruses can be likened to mobile, genetic elements. He said: "Viruses actually form part of the web of life.
"I would expect that if you've got microbial life on another planet, you're bound to have – if it's going to be sustainable and sustained – the full complexity and robustness that will go with being able to exchange genetic information."
He also mentioned a number of studies that have linked the possibility of a process where genetic material from viruses gets incorporated into the genomes of humans and other animals – it is called horizontal gene transfer.
Mr Davies said that horizontal gene transfer is something that is possible if cellular alien life is somewhere out there in the universe.

“Most people think about, well, we would need to have very large spacecraft"

He added: “A friend of mine thinks most, but certainly a significant fraction, of the human genome is actually of viral origin."
Mr Davies also believes that if there is alien life, he highly doubts that it would be homogenous.
He stated: “I don’t think it’s a matter that you go to some other planet, and there will just be you one type of microbe and it’s perfectly happy. I think it’s got to be a whole ecosystem,”
But while this may seem alarming, Mr Davies is confident that this will not pose a threat to the human race.
He said: “The dangerous viruses are those that are very closely adapted to their hosts. If there is a truly alien virus, then chances are it wouldn't be remotely dangerous,"
“We hear about the microbiome inside us, and there's a planetary microbiome."
These comments come after a recent study led by researchers at The University of Cambridge identified that vast exoplanets with hydrogen-rich atmospheres were discovered in the universe.
The experts said this breakthrough might even lead to the discovery of alien life within two to three years.
Talking about the possibility of discovering alien life, Mr Davies said: “Most people think about, well, we would need to have very large spacecraft, and then sort of recycle things for the very long journey, and then all the technology you’d need to take.
“Actually, the toughest part of this problem is what would be the microbiology that you’d have to take – it’s no good just taking a few pigs and potatoes and things like that and hoping when you get to the other end it’ll all be wonderful and self-sustainable.”
Mr Davies new book, What’s Eating the Universe?, was published last week.
If we ever do find alien life, we may also discover their viruses – or at least that’s what one scientist has claimed. Professor Paul Davies, who is an astrobiologist, cosmologist and director of the Beyond Center for Fundamental Concepts in Science at Arizona State University, stated that viruses might be an important factor in the ecosystems on other planets.
Alien life on other planets doesn’t necessarily mean an advanced civilization of humanoids with a large head and bulging eyes – although that’s a possibility as well – but they could also be microbes and that’s where the theory of viruses comes from as explained by Davies, “Viruses actually form part of the web of life.” “I would expect that if you’ve got microbial life on another planet, you’re bound to have – if it’s going to be sustainable and sustained – the full complexity and robustness that will go with being able to exchange genetic information.”
He went on to say that if there is cellular life on other planets, the viruses would be able to move genetic information from one to the others. Additionally, there would probably be an entire ecosystem of microbes instead of just one specific type.
But there’s no need to hide just yet as Davies stated that if there are viruses on other planets, humans here on Earth have nothing to fear. “The dangerous viruses are those that are very closely adapted to their hosts,” he explained. “If there is a truly alien virus, then chances are it wouldn’t be remotely dangerous.” To be more specific, the virus would be more harmful to anything alive on the alien planet rather than being dangerous to Earthlings. This is because the virus wouldn’t have had a chance to infect humans, evolve, and spread. I don’t know about you, but I don’t find that very comforting or reassuring.
Would aliens sneeze like humans?
This would certainly be a factor if humans were to colonize another planet, but Davies has claimed that the majority of viruses are good. “I think without viruses, there may be no sustained life on planet Earth.” Really? COVID-19 is caused by a virus and it has already claimed more than 4.5 million lives. This is certainly one virus we could live without.
If there are aliens viruses out in space somewhere, let’s hope they don’t find their way here.
Over the decades it has been claimed that elements of the U.S. Government may have more than a few “unacknowledged aircraft,” hidden away, so to speak. In simple terms, we’re talking about secret aircraft that, despite sightings of them, no-one in government wants to reveal them for what they are. Or, were. We’ll begin with what has become known as the Aurora. In the early 1990s, rumors began to circulate among the aviation world that a highly secret, futuristic aircraft was being flown out of Area 51 – and under distinctly covert circumstances. The reportedly large, black-colored, triangular-shaped aircraft which could fly at incredible speeds, could outmaneuver just about anything else on the planet. It was rumored to be known as the Aurora. Officially, at least, and according to the U.S. Government, the Aurora does not exist and has never existed. But, that was once said about Area 51, too. So, with that in mind, we need to tread cautiously when it comes to official proclamations of the controversial type.
An artist’s conception of the Aurora aircraft.
The story began – publicly, at least – in March 1990. That was when the well-respected magazine Aviation Week & Space Technologycovered the story. They revealed that the term Aurora had appeared in the 1985 U.S. budget – and had possibly appeared by mistake, which makes sense if the program was so highly sensitive that its existence had to be denied at all costs. And talking of costs, it was rumored that around $455 million had been provided to those working out at Area 51 on secret, futuristic aircraft. AW&ST suspected that Aurora was a code-name for multiple kinds of aircraft that were both radical in design and technology. Other investigators, though, concluded that Aurora referred to just one type of aircraft. AW&ST learned that by 1987 the budget had soared to in excess of two billion dollars. Bill Sweetman is one of the leading figures in the field of aviation and someone who took a deep interest in the Aurora saga. His books include F-22 Raptor, Inside the Stealth Bomber, and Soviet Air Power. And, then there is his 1993 book, Aurora: The Pentagon’s Secret Hypersonic Spyplane. Of the Aurora, Sweetman says: “Does Aurora exist? Years of pursuit have led me to believe that, yes, Aurora is most likely in active development, spurred on by recent advances that have allowed technology to catch up with the ambition that launched the program a generation ago.”
Now, let’s have a look at the TR-3A. It was around 11:00 p.m. on September 26, 1994, when a small, twin-tailed aircraft crash-landed onto the lengthy runway at Boscombe Down, which is situated in the English county of Wiltshire. At around the time of the incident, a number of aviation enthusiasts were listening in on air-band radios and were aware that something untoward had taken place. The following day, several of those same enthusiasts drove to the installation – which is near to the A303 road and not at all far from Stonehenge – and were apprehended by local police who had set up road-blocks to keep away prying eyes. Before being ushered away, however, a number of people succeeded in catching sight of a disabled aircraft. It was situated at the end of the runway and, aside from its twin-tail fins, was completely covered over by tarpaulins. Air Force Monthly magazine was soon on the trail of the truth. In the November 1994 issue of the magazine, investigative writers noted that in the wake of the crash both a Boeing757 and a C-5 Galaxy arrived at Boscombe Down. The story continued that the secret plane was loaded aboard the Galaxy and flown to “Air Force plant 42 at Palmdale, California.” Air Force Monthly suggested that the aircraft “”…was a TR-3A, the existence of which the U.S. Government has yet to officially acknowledge.” The subsonic, stealth TR-3A – also referred to as the Black Manta – remains an enigma, since its existence has never been officially confirmed. Now, what about the Flying Triangles? They have that specific name for a reason: they’re large, black, silent, fast-flying craft hat even have the ability to hover in silence. Some aircraft experts believe the FTs are next-generation Stealth planes. Many people in the UFO research community are of the opinion that the FTs are alien spacecraft. The debate still goes on – after more than several decades of investigation and research.
In 1989 there was a wave of Flying Triangle encounters over Belgian. Nick Pope, still in the employ of the U.K. Ministry of Defense at the time, told me in an interview, after a wave of FT encounters in the U.K. in 1993: “I approached the Belgians to get a comparison after their sightings. I phoned the Air Attaché at the British Embassy in Brussels and he spoke to one of the F-16 pilots who had been scrambled to intercept a Flying Triangle over Belgium back in 1990. Well, the Air Attaché reported back to me that the corporate view of the Belgian Defense Staff was that they did believe that they were dealing with a solid, structured craft. Apparently, the word from the Belgians was: ‘Thank God it was friendly.’ If it hadn’t been, it was made clear to me that there was very little that the Belgian Air Force could have done anyway – despite the fact that the F-16 is no slouch.” The one thing all of these aircraft have in common? I’ll tell you: They’re still undeniably secret.
Three “Potentially Dangerous” Asteroids to Closely Pass by Earth This Month Jocelyne LeBlanc September 10, 2021 FACEBOOK TWITTER GOOGLE+ Three asteroids that have been deemed as being “potentially dangerous” will pass by our plane
Three “Potentially Dangerous” Asteroids to Closely Pass by Earth This Month
Three asteroids that have been deemed as being “potentially dangerous” will pass by our planet this month of September at a fairly close distance. The space rocks will travel by us on September 9th, 11th, and 22nd. With that being said, let’s take a quick look at these three asteroids.
Asteroid 2010 RJ53 is flying by our planet today (September 9th) at a distance of about 366,000 kilometers away (227,422 miles). To put this into better perspective, our moon is located at a distance of around 384,400 kilometers (238,855 miles) which means that 2010 RJ53 will be closer to us than our moon. This asteroid, which measures 774 meters (2,539 feet), was discovered on September 10, 2010. It completes a full orbit around our sun every 402 days. At its furthest distance, it is 224 million kilometers away from the sun (139 million miles), with its closest approach measuring 95 million kilometers (59 million miles).
On September 11th, asteroid 2021 PT will travel within 4.9 million kilometers from Earth (3 million miles). This asteroid measures approximately 137 meters in diameter (449 feet).
Then on September 22nd, a third asteroid will closely pass by Earth. Asteroid 2021 NY1 will fly by within a distance of 1,498,113 kilometers (930,884 miles). To understand this better, it will be approximately 3.89 times further than the moon is to us. This space rock, which has been categorized as both a Potentially Hazardous Asteroid (PHA) by NASA’s Jet Propulsion Laboratory (JPL) as well as a near-Earth object (NEO), is expected to measure anywhere between 130 and 300 meters in diameter (427 to 984 feet). This asteroid has an orbit of 0.01 Astronomical Units (AU) or approximately 1.5 million kilometers from our planet (932,000 miles) – one AU is the distance of Earth from our sun. Additionally, when 2021 NY1 passes by us on the 22nd of the month, it will be the closest that it has been to our planet in nearly a century and it won’t get close to us again until about the year 2105 when it is expected to be approximately 2.65 million kilometers away (1.65 million miles).
While these three asteroids will be fairly close to Earth when they travel through space, there is no need to worry or hide in a bunker as they aren’t expected to hit our planet.
This is a 3D-Printed Steel Floor Prototype for a Lunar Habitat
This is a 3D-Printed Steel Floor Prototype for a Lunar Habitat
In this decade, multiple space agencies and commercial space entities will be taking us back to the Moon. But unlike the Apollo Era, the goal of these programs is not “footprints and flags,” but to establish the necessary infrastructure to keep going back. In particular, NASA, the ESA, Roscosmos, and China are all planning on establishing outposts that will allow for scientific research and a sustained human presence.
The ESA is currently showcasing what its outpost will look like at the 17th annual Architecture Exhibition at the La Biennale di Venezia museum in Venice. It’s known as the International Moon Village, which was designed by the architecture firm Skidmore, Owings & Merrill (SOM) with technical support from the ESA. This same company recently unveiled a prototype of the skeletal metal component that will one day be part of the Village’s lunar habitats.
The component was built by MX3D, an Amersterdam-based 3D printing architecture and design firm specializing in Wire Arc Additive Manufacturing (WAAM). This process involves fusing metal wires with lasers to create lightweight metal objects with high structural strength. The company is renowned for creating the 3D printed metal bridge that spans the Oudezijds Achterburgwal canal in Amsterdam (shown below).

The skeletal, smooth web pattern will be part of the flooring for each habitat that collectively makes up the ESA’s International Lunar Village. The prototype was created using a robotic 3D printer out of 308LSi stainless steel over the course of about 10 days (246 hours), measures 4.5 m (~15 ft) in diameter, and has a total mass of approximately 395 kg (over 870 lbs). As ESA Advanced Manufacturing Engineer Advenit Makaya said in a recent ESA press release:
“This is a remarkable achievement from MX3D, which further highlights the potential of this additive manufacturing technique for an increasing range of space applications. The design flexibility and the possibility to combine the printed structure with embedded monitoring systems – as demonstrated in the 3D-printed bridge in Amsterdam – are worth investigating for applications in space structures. This technique could also be considered for in-situ construction of infrastructure during sustainable exploration missions, for instance by using metallic feedstock derived from the locally available regolith.”
The floor component consists of six separate segments that were printed vertically before being welded together. When integrated with SOM’s design for a four-story semi-inflatable habitat, the 3D printed structure will be supported by three columns and covered by a series of floor panels. Unfortunately, SOM could not feature it as part of their exhibit – titled “Life Beyond Earth” – but manages to convey the scale of the lunar habitats that they are developing. Said Daniel Inocente, SOM’s Senior Designer for the study:
“The innovative floor design is supported from columns in the habitat walls, cantilevering towards the perimeter and centre. We looked at the manufacturing constraints and used our analysis to interpolate a web pattern that followed the angular limits of the 3D printing machines. The cross section and thickness was also analysed and differentiated to reduce the overall mass – with reduced thickness at the exterior/interior boundaries.”

The flooring and manufacturing process are consistent with SOM’s habitat design, which calls for four-story semi-inflatable shells that collectively make the International Lunar Village. Each semi-inflatable shell structure measures four stories high and offers the highest possible volume to mass ratio. Once inflated on the lunar surface, each of these habitats will approximately double its original internal volume.
The module’s inflatable design allows it to be compressed for the sake of transport and then inflated to its full size once it is deployed to the lunar surface. But unlike previous inflatable designs, where the structural and mechanical systems are typically at the center, SOM’s design allows for an open interior that optimizes the living experience. In addition to showcasing a key component in the proposed lunar habitat, the floor element demonstrates the effectiveness of the 3D printing method involved. As Gijs van der Velden, CEO of MX3D, explained:
“This was a great opportunity to show the potential of our technology for the fabrication of lightweight metal structures together with ESA and SOM. It was a perfect project for MX3D to leverage its experience in printing topology optimised metal structures. Achieving an optimal use of material is a company goal at MX3D because – just as when designing space applications – every reduced kilo in a MX3D design is a direct win for a project’s feasibility.”
“The capabilities of MX3D demonstrate inspiring concurrence of engineering and art, and are another great example to what extent additive manufacturing has already entered our society,” added Thomas Rohr, Head of the Materials and Processes team at ESA. “For space applications, such technologies not only provide improvements in performance but can lead to unprecedented and enabling design solutions.”
The International Moon Village project is a multidisciplinary effort initiated by the ESA and developed in collaboration with Jeffrey A. Hoffman – a former NASA astronaut and a Professor of Aeronautics and Astronautics at MIT. Similarly, the project is in keeping with the theme of the Biennale Architettura 2021 – “How will we live together?” – which features 112 participants in competition from 46 countries.
The purpose of this exhibition is to promote ideas for coexistence and sustainability in response to global problems. The International Moon Village exhibit is intended to show how space-related research and solutions for space habitation have applications here on Earth. Like all plans for establishing a human presence on the Moon, the key to the design is in-situ resource utilization (ISRU) and sustainability.
For example, the ESA plans to deploy the Moon Village in the Moon’s southern polar region – aka. The South Pole-Aitken Basin. In the permanently shadowed craters that mark this region, there is abundant water ice that could be harvested and used for the sake of drinking water, irrigation, and the creation of oxygen gas and rocket fuel. In addition, power can be provided by deploying solar arrays around the crater rims, which are exposed to near-continuous daylight.
This arrangement allows for a degree of resource self-sufficiency, reducing the need for resupply missions from Earth, thus reducing overall costs. As a means of manufacturing, 3D metal printing is also incredibly efficient and wastes far less material than traditional machining. These technologies will have similar applications here at home, promoting sustainable living solutions to reduce our impact on the natural environment.
