Russian Space Head Accuses U.S. and Elon Musk of Planning Nuclear War in Space
Russian Space Head Accuses U.S. and Elon Musk of Planning Nuclear War in Space
At the time of this writing, Elon Musk’s SpaceX rocket had not yet launched humans into space, but even a successful mission probably won’t quell the wrath of the head of Russia’s space agency. No, he’s not just mad about losing the business of taking astronauts to the ISS and back – it’s much worse than that.
“We understand that one thing stands behind all this demagogy: this is a cover for deployment of nuclear weapons in space. We see such attempts, we consider them unacceptable and we will oppose them as much as we can.”
In an interview on the YouTube podcast “Solovyov LIVE” (watch it here in Russian), Dmitry Rogozin, the head of Russian state space agency Roscosmos, told host Vladimir Solovyov that he believes Musk is serious about detonating 10,000 nuclear warheads on Mars to terraform the planet into one with an atmosphere and climate that can support humans, and Musk’s SpaceX partnership with NASA is proof that the U.S. government approves of it.
“We have commented on each and every such anti-Russian attack which are all nothing but the United States’ attempt to divert public attention from real threats in space and to justify its moves to deploy weapons in outer space and obtain extra financing for such causes.”
Russian Foreign Ministry Spokeswoman Maria Zakharova told TASS last month that Russia is not happy with the Space Force, especially with its announcement of the unveiling of its first weapon (a satellite jammer) and its first mission with the mysterious X-37B space plane – both occurring within the past month. And now … SpaceX and its CEO and founder’s grandiose nuclear plans for Mars, with no denunciation by NASA or the U.S. government. In fact, President Trump had this to say about Elon Musk back in February:
“He likes rockets. And he does good at rockets, too, by the way.”
So does Roscosmos, which has managed to shuttle crews and cargo reliably to the ISS ever since NASA shut down the space shuttle program. Roscosmos has announced that it is lowering its costs for launches, which are already less that SpaceX, so it knows this escalation of a Cold War in space is not about money.
“We see such attempts, we consider them unacceptable and we will hinder this to the greatest extent possible.”
“Hinder” … what could that entail? Deploying its own space weapons – both known and secret? Cyberwarfare? Accelerating Russia’s own plans to send humans to Mars? For now, it’s a battle of words where Russia is taking the human rights side for a change.
“It is absolutely obvious that the idea to bomb Mars with nuclear charges is absolutely abhorrent from a humanitarian standpoint. Who gave him right to destroy a planet?”
That’s a good question, Dmitry Rogozin. Does Earth money talk on Mars?
If the first launch of humans by SpaceX is successful, we may soon find out
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
Astronomers are convinced that asteroids Bennuand Ryugucame from the same much bigger space rock that split apart. Both of these asteroids, which orbit between Earth and Mars, are believed to have been formed following the creation of two centers of gravity.
Bennu was discovered in September of 1999 by astronomers in Socorro, New Mexico. The asteroid measures 1,610 feet in diameter. Astronomers in Socorro also discovered Ryugu a few months before in May of 1999 and that asteroid measures 3,280 feet in diameter.
Rock samples from both of these asteroids will need to be analyzed in order to know for sure if they came from the same space rock. Samples have already been taken from Ryugu and are currently on their way back to Earth on Japan’s Hayabusa2 spacecraft which is scheduled to return to our planet later this year.
Bennu
No samples have been taken yet from Bennu, although NASA’s OSIRIS-REx is expected to land on the asteroid on October 20th of this year to collect the specimens. The spacecraft will land on a site called “Nightingale” located in the northern hemisphere of the asteroid and it will then collect samples about 0.8 inches in diameter.
Astronomers from the University of Arizona and Laboratoire Lagrange, Ivory Coast, simulated different collisions that could have taken place in the Mars-Jupiter asteroid belt. In their models, they found that pieces of asteroids would be ejected from the rock but would assemble back together in a spinning-top shape which is similar to both Bennu and Ryugu.
Even though the asteroids are different in regards to their hydration levels, they could very well still be from the same space rock. Once the samples from both asteroids come back to Earth, experts will be able to verify for certain if they’re related by determining their age as well as what they are composed of. Pictures of both asteroids can be seen here.
Ryugu
A really interesting fact about the pictures that Hayabusa2 took of Ryugu is that some of the rocks on its surface are reddish in color, suggesting that at some point it traveled pretty close to the sun.
In their paper, planetary scientist Tomokatsu Morota from the University of Tokyo as well as his colleagues wrote in part, “Immediately after touchdown, Hayabusa2’s thrusters disturbed dark, fine grains that originate from the redder materials.” They went on to say, “The stratigraphic relationship between identified craters and the redder material indicates that surface reddening occurred over a short period of time,” adding, “We suggest that Ryugu previously experienced an orbital excursion near the Sun.” The study was published in Nature Communications and can be read here in full here.
I Found A Plane Crash Using Google Earth Map, Video, UFO Sighting News.
I Found A Plane Crash Using Google Earth Map,Video,UFO Sighting News.
Date of discovery: May 28, 2020 Location of discovery: Yukatan Google Coordinates: 20°58'18.24"N 90°17'0.13"W
I was using Google Earth to look for UFOs and alien bases, when I accidentally came across this plane crash. One wing is partly buried under the trees but its clear that its a plane. The plane measures 20 meters from nose to tail and 28 meters from wing tip to wing tip. The plane appears to be whole and could probably fly again if it was retrieved and repaired. However I do believe that the pilot may be dead in side since it hit the trees and branches may have broken through the cockpit windows. I don't see any trials going in or out of that area, so I believe this crash to be unknown or undiscovered until now. Its not the only plane crash I have discovered. I found flight MH370 under 3 meters of water off the coast of Cape of Good Hope, South Africa on Google Earth Map. I reported it to the Airline that lost it, but they didn't respond, probably because if the flight is found, they will be forced to pay hundreds of millions of dollars to the families. If its not found, they they only pay a tiny sum. Therefore they don't wont to find it. Scott C. Waring
This triangle-shaped craft was filmed in the night sky above Lemoore, California back in June 2019. What do you think about this footage?
Witness report:
My girlfriends family were driving from Lemoore and started recording as soon as they seen the craft. It flew away and then made a turn, and hovered right over the car. The car was shaking a lot and was very scary lol. The craft didn’t even make loud noise which was very strange.
WETENSCHAPOnze planeet heeft vijf grote massa-extincties gekend. Een daarvan is de Laat-Devonische extinctie, die zo’n 359 miljoen jaar geleden plaatsvond. De oorzaak wordt doorgaans gezocht in een meteorietinslag, maar uit een nieuwe studie blijkt dat de snelle klimaatopwarming en het wegvallen van de beschermende ozonlaag aan de basis liggen. De wetenschappers waarschuwen voor een gelijkaardig scenario als we de huidige opwarming van de aarde niet onder controle krijgen.
De bekendste massa-extinctie in de geschiedenis van de aarde is die van 66 miljoen jaar geleden, toen de dinosauriërs werden uitgeroeid. De minder gekende Laat-Devonische massa-extinctie vond veel vroeger plaats: de belangrijkste uitsterving toen gebeurde vlak voor de Devoon-Carboon-grens, ongeveer 359 miljoen jaar geleden. De Laat-Devonische massa-extinctie had vooral fatale gevolgen voor dieren die in het water leefden en voor planten.
Meestal wordt uitgegaan van een meteorietinslag die net voor de overgang van het Devoon naar het Carboon de enorme extinctie van heel wat mariene en plantensoorten veroorzaakte. Maar sommige microscopisch kleine sporen (voortplantingscellen) van varenachtige planten, ontdekt in gesteenten uit het oosten van Groenland, bleken misvormd te zijn, zo stelt het nieuwe onderzoek dat gepubliceerd is in Science Advances. Volgens de wetenschappers bewijst de beschadiging van het DNA van de planten dat “de hele ozonbescherming verdwenen was”. De verhoogde UV-B-straling wijst immers op een snelle en dramatische verdunning van de ozonlaag, de laag die het leven op aarde beschermt tegen schadelijke stralingen van de zon, zoals tegen UV-straling. Door het wegvallen van die beschermende ozonlaag werd het leven op onze planeet blootgesteld aan een explosie van ultraviolette straling die mutaties veroorzaakte.
Wetenschappers gaan doorgaans uit van twee mogelijke oorzaken van uitroeiingsgebeurtenissen: enorme vulkaanuitbarstingen of meteorietinslagen. Uit kwikgegevens leidt de nieuwe studie af dat er in dit geval geen vulkaanuitbarstingen op planetaire schaal plaatsvonden, in tegenstelling tot bij andere massa-extincties. De massa-extinctie van 359 miljoen jaar geleden zou wél te maken hebben gehad met de grote klimaatopwarming, die een einde maakte aan de intense laatste ijstijdcyclus in het Devoon. De onderzoekers waarschuwen dan ook voor mogelijk gelijkaardige, dramatische gevolgen van de huidige snelle klimaatverandering, waarvoor de mens zélf verantwoordelijk is. “Ozonverlies tijdens de snelle opwarming van de aarde is een proces dat inherent is aan het systeem, met de onvermijdelijke conclusie dat we alert moeten zijn voor zo’n gebeurtenis in de toekomst van onze opwarmende wereld”, klinkt het.
WETENSCHAP & PLANEETDe Europese zonneverkenner Solar Orbiter zal de komende dagen de staarten van de komeet ATLAS doorkruisen. Dat heeft het Europese Ruimtevaartbureau ESA gemeld. Hoewel het onbemande ruimtetuig op dit moment geen wetenschappelijke data zou verzamelen, hebben missiedeskundigen ervoor gezorgd dat de vier belangrijkste instrumenten tijdens de unieke gebeurtenis actief worden.
De Solar Orbiter werd gelanceerd op 10 februari. Sindsdien hebben wetenschappers en ingenieurs, met uitzondering van een korte onderbreking als gevolg van de coronapandemie, een reeks tests en opstellingsroutines uitgevoerd die bekendstaan als ‘ingebruikname’.
De einddatum voor deze fase is 15 juni, zodat het ruimtetuig twee dagen later volledig functioneel kan zijn tijdens zijn eerste passage vlakbij de zon ofwel perihelium. De ontdekking van deze onverwachte ontmoeting met de komeet maakte de zaken echter dringender.
Rustig vliegen door de staart van een komeet is volgens ESA een zeldzame gebeurtenis voor een ruimtemissie, iets waarvan wetenschappers weten dat het nog maar zes keer eerder is gebeurd voor missies die niet specifiek op kometen jagen. Al deze ontmoetingen zijn pas achteraf ontdekt met behulp van de data van het ruimtetuig. De aankomende doorsteek van Solar Orbiter is de eerste die van tevoren wordt voorspeld.
De eigenlijke missie van de Solar Orbiter is nieuwe informatie te vergaren over de zon, onder meer door beelden te maken van de noord- en zuidpool van die ster. Vermoed wordt dat die polen een rol spelen in het ontstaan van zonnevlammen, die de elektronica hier op Aarde kunnen verstoren.
Het gaat om een gezamenlijk project van de NASA en het Europese ruimtevaartagentschap ESA, waarbij ook een prominente rol is weggelegd voor de Koninklijke Sterrenwacht van België. De sonde omvat immers de EUI-telescoop van de Koninklijke Belgische Sterrenwacht en het Centre spatial de Liège.

In Planet Formation, It's Location, Location, Location
Astronomers using NASA’s Hubble Space Telescope are finding that planets have a tough time forming in the rough-and-tumble central region of the massive, crowded star cluster Westerlund 2. Located 20,000 light-years away, Westerlund 2 is a unique laboratory to study stellar evolutionary processes because it’s relatively nearby, quite young, and contains a large stellar population.
The brilliant tapestry of young stars flaring to life resembles a glittering fireworks display in this Hubble Space Telescope image. The sparkling centerpiece of this fireworks show is a giant cluster of thousands of stars called Westerlund 2. The cluster resides in a raucous stellar breeding ground known as Gum 29, located 20,000 light-years away from Earth in the constellation Carina. Hubble’s Wide Field Camera 3 pierced through the dusty veil shrouding the stellar nursery in near-infrared light, giving astronomers a clear view of the nebula and the dense concentration of stars in the central cluster. The cluster measures between six light-years and 13 light-years across.

A three-year Hubble study of stars in Westerlund 2 revealed that the precursors to planet-forming disks encircling stars near the cluster’s center are mysteriously devoid of large, dense clouds of dust that in a few million years could become planets.
However, the observations show that stars on the cluster’s periphery do have the immense planet-forming dust clouds embedded in their disks. Researchers think our solar system followed this recipe when it formed 4.6 billion years ago.
So why do some stars in Westerlund 2 have a difficult time forming planets while others do not? It seems that planet formation depends on location, location, location. The most massive and brightest stars in the cluster congregate in the core, which is verified by observations of other star-forming regions. The cluster’s center contains at least 30 extremely massive stars, some weighing up to 80 times the mass of the Sun. Their blistering ultraviolet radiation and hurricane-like stellar winds of charged particles blowtorch disks around neighboring lower-mass stars, dispersing the giant dust clouds.
“Basically, if you have monster stars, their energy is going to alter the properties of the disks around nearby, less massive stars,” explained Elena Sabbi, of the Space Telescope Science Institute in Baltimore and lead researcher of the Hubble study. “You may still have a disk, but the stars change the composition of the dust in the disks, so it’s harder to create stable structures that will eventually lead to planets. We think the dust either evaporates away in 1 million years, or it changes in composition and size so dramatically that planets don’t have the building blocks to form.”
The Hubble observations represent the first time that astronomers analyzed an extremely dense star cluster to study which environments are favorable to planet formation. Scientists, however, are still debating whether bulky stars are born in the center or whether they migrate there. Westerlund 2 already has massive stars in its core, even though it is a comparatively young, 2-million-year-old system.
Using Hubble’s Wide Field Camera 3, the researchers found that of the nearly 5,000 stars in Westerlund 2 with masses between 0.1 to 5 times the Sun’s mass, 1,500 of them show fluctuations in their light as the stars accrete material from their disks. Orbiting material clumped within the disk would temporarily block some of the starlight, causing brightness fluctuations.
However, Hubble detected the signature of such orbiting material only around stars outside the cluster’s packed central region. The telescope witnessed large drops in brightness for as much as 10 to 20 days around 5% of the stars before they returned to normal brightness. They did not detect these dips in brightness in stars residing within four light-years of the center. These fluctuations could be caused by large clumps of dust passing in front of the star. The clumps would be in a disk tilted nearly edge-on to the view from Earth. “We think they are planetesimals or structures in formation,” Sabbi explained. “These could be the seeds that eventually lead to planets in more evolved systems. These are the systems we don’t see close to very massive stars. We see them only in systems outside the center.”
Thanks to Hubble, astronomers can now see how stars are accreting in environments that are like the early universe, where clusters were dominated by monster stars. So far, the best known nearby stellar environment that contains massive stars is the starbirth region in the Orion Nebula. However, Westerlund 2 is a richer target because of its larger stellar population.
“Hubble’s observations of Westerlund 2 give us a much better sense of how stars of different masses change over time, and how powerful winds and radiation from very massive stars affect nearby lower-mass stars and their disks,” Sabbi said. “We see, for example, that lower-mass stars, like our Sun, that are near extremely massive stars in the cluster still have disks and still can accrete material as they grow. But the structure of their disks (and thus their planet-forming capability) seems to be very different from that of disks around stars forming in a calmer environment farther away from the cluster core. This information is important for building models of planet formation and stellar evolution.”
This cluster will be an excellent laboratory for follow-up observations with NASA’s upcoming James Webb Space Telescope, an infrared observatory. Hubble has helped astronomers identify the stars that have possible planetary structures. With Webb, researchers can study which disks around stars are not accreting material and which disks still have material that could build up into planets. This information on 1,500 stars will allow astronomers to map a path on how star systems grow and evolve. Webb also can study the chemistry of the disks in different evolutionary phases and watch how they change, and help astronomers determine what influence environment plays in their evolution.
NASA’s Nancy Grace Roman Space Telescope, another planned infrared observatory, will be able to perform Sabbi’s study on a much larger area. Westerlund 2 is just a small slice of an immense star-formation region. These vast regions contain clusters of stars with different ages and different densities. Astronomers could use Roman Space Telescope observations to start to build up statistics on how a star’s characteristics, like its mass or outflows, affect its own evolution or the nature of stars that form nearby. The observations could also provide more information on how planets form in tough environments.
The Hubble Space Telescope is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy in Washington, D.C.

New Earth Found Orbiting Proxima Centauri, Our Closet Neighbor Star
New Earth Found Orbiting Proxima Centauri, Our Closet Neighbor Star
The existence of a planet the size of Earth around the closest star in the solar system, Proxima Centauri, has been confirmed by an international team of scientists including researchers from the University of Geneva (UNIGE). The results, which you can read all about in the journal Astronomy & Astrophysics, reveal that the planet in question, Proxima b, has a mass of 1.17 earth masses and is located in the habitable zone of its star, which it orbits in 11.2 days.
This artist’s impression shows a view of the surface of the planet Proxima b orbiting the red dwarf star Proxima Centauri, the closest star to the Solar System.
This breakthrough has been possible thanks to radial velocity measurements of unprecedented precision using ESPRESSO, the Swiss-manufactured spectrograph – the most accurate currently in operation – which is installed on the Very Large Telescope in Chile. Proxima b was first detected four years ago by means of an older spectrograph, HARPS – also developed by the Geneva-based team – which measured a low disturbance in the star’s speed, suggesting the presence of a companion.
The ESPRESSO spectrograph has performed radial velocity measurements on the star Proxima Centauri, which is only 4.2 light-years from the Sun, with an accuracy of 30 centimetres a second (cm/s) or about three times more precise than that obtained with HARPS, the same type of instrument but from the previous generation.
“We were already very happy with the performance of HARPS, which has been responsible for discovering hundreds of exoplanets over the last 17 years”, begins Francesco Pepe, a professor in the Astronomy Department in UNIGE’s Faculty of Science and the man in charge of ESPRESSO. “We’re really pleased that ESPRESSO can produce even better measurements, and it’s gratifying and just reward for the teamwork lasting nearly 10 years.”

Shining brightly in this Hubble image is our closest stellar neighbour: Proxima Centauri. Proxima Centauri lies in the constellation of Centaurus (The Centaur), just over four light-years from Earth. Although it looks bright through the eye of Hubble, as you might expect from the nearest star to the Solar System, Proxima Centauri is not visible to the naked eye.
Alejandro Suarez Mascareño, the article’s main author, adds: “Confirming the existence of Proxima b was an important task, and it’s one of the most interesting planets known in the solar neighbourhood.”
The measurements performed by ESPRESSO have clarified that the minimum mass of Proxima b is 1.17 earth masses (the previous estimate was 1.3) and that it orbits around its star in only 11.2 days.
Artist’s impression of the exoplanet Proxima Centauri b shown as of a arid (but not completely water-free) rocky Super-Earth. This appearance is one of several possible outcomes of current theories regarding the development of this exoplanet, while the actual look and structure of the planet is known in no ways at this time. Proxima Centauri b is the closest exoplanet to the Sun and also the closest potentially habitable exoplanet as well. It orbits Proxima Centauri, a red dwarf with a surface temperature of 3040 K (thus hotter than light bulbs and therefore whiter, as depicted here). The Alpha Centauri binary system is shown in the background.

“ESPRESSO has made it possible to measure the mass of the planet with a precision of over one-tenth of the mass of Earth”, says Michel Mayor, winner of the Nobel Prize for Physics in 2019, honorary professor in the Faculty of Science and the ‘architect’ of all ESPRESSO-type instruments. “It’s completely unheard of.”
And what about life in all this?
Although Proxima b is about 20 times closer to its star than the Earth is to the Sun, it receives comparable energy, so that its surface temperature could mean that water (if there is any) is in liquid form in places and might, therefore, harbour life.
Having said that, although Proxima b is an ideal candidate for biomarker research, there is still a long way to go before we can suggest that life has been able to develop on its surface. In fact, the Proxima star is an active red dwarf that bombards its planet with X rays, receiving about 400 times more than the Earth.
“Is there an atmosphere that protects the planet from these deadly rays?” asks Christophe Lovis, a researcher in UNIGE’s Astronomy Department and responsible for ESPRESSO’s scientific performance and data processing. “And if this atmosphere exists, does it contain the chemical elements that promote the development of life (oxygen, for example)? How long have these favourable conditions existed? We’re going to tackle all these questions, especially with the help of future instruments like the RISTRETTO spectrometer, which we’re going to build specially to detect the light emitted by Proxima b, and HIRES, which will be installed on the future ELT 39 m giant telescope that the European Southern Observatory (ESO) is building in Chile.”
Surprise: is there a second planet?
In the meantime, the precision of the measurements made by ESPRESSO could result in another surprise. The team has found evidence of a second signal in the data, without being able to establish the definitive cause behind it. “If the signal was planetary in origin, this potential other planet accompanying Proxima b would have a mass less than one third of the mass of the Earth. It would then be the smallest planet ever measured using the radial velocity method”, adds Professor Pepe.
It should be noted that ESPRESSO, which became operational in 2017, is in its infancy and these initial results are already opening up undreamt of opportunities. The road has been travelled at breakneck pace since the first extrasolar planet was discovered by Michel Mayor and Didier Queloz, both from UNIGE’s Astronomy Department. In 1995, the 51Peg b gas giant planet was detected using the ELODIE spectrograph with an accuracy of 10 meters per second (m/s). Today ESPRESSO, with its 30 cm/s (and soon 10 after the latest adjustments) will perhaps make it possible to explore worlds that remind us of the Earth.

The Anunnaki are a group of deities who appear in the mythological traditions of the ancient Sumerians, Akkadians, Assyrians, and Babylonians. Descriptions of how many Anunnaki there were and what role they fulfilled are inconsistent and often contradictory.
Pilot And Crew’s Alien Craft Encounter Over Alaska
Pilot And Crew’s Alien Craft Encounter Over Alaska
NOVEMBER 16, 1986 ……FLIGHT FROM PARIS TO ALASKA
It was just a routine flight. Well, not exactly routine… It was a special Japan Air Lines 747 cargo flight to carry a load of French wine from Paris to Tokyo.
The flight plan would carry flight 1628 from Paris to Reykjavik, Iceland, across the North Atlantic and Greenland, then across Canada to Anchorage, Alaska, and finally across the Pacific to Tokyo.
The crew consisted of veteran Captain Kenju Terauchi, co-pilot Takanori Tamefuji, and flight engineer Yoshio Tsukuba.
On November 16, 1986, laden with wine, JAL1628 took off from Paris and flew the first leg of the trip, to Reykjavik. The next day, they continued, flying over Greenland and then across northern Canada without event.
Just after they crossed into Alaska, at 5:09 PM local time, Anchorage Air Traffic Control contacted them on the radio to report initial radar contact. The Anchorage flight controller asked them to turn 15 degrees to the left and head for a point known as Talkeetna on a heading of 215 degrees. They were at 35,000 feet and traveling at a ground speed of about 600 mph.
At about 5:11 PM local time, Captain Terauchi noticed the lights of some sort of aircraft about 2000 feet below and 30 degrees to the left front of them. He decided that the aircraft was probably an American jet fighter from nearby Eielson or Elmendorf Air Force Bases patrolling Alaskan airspace, so he ignored them at first.
However, after a few minutes, he noticed that the lights were keeping pace with his own aircraft, which would be an unusual thing for patrolling jets to do.
It was about seven or so minutes since we began paying attention to the lights (when), most unexpectedly, two spaceships stopped in front of our face, shooting off lights. The inside cockpit shined brightly and I felt warm in the face.
Terauchi said that it was his impression that the two objects he had seen below them minutes before had suddenly jumped in from of him. The craft, one above the other, kept pace with the 747 for several minutes, moving in unison with an odd rocking motion.
After about seven minutes, they changed to a side-by-side arrangement.
Terauchi said that the “amber and whitish” lights were like flames coming out of multiple rocket exhaust ports arranged in two rectangular rows on the craft. He felt that they fired in a particular sequence to stabilize the craft, much like the small maneuvering thrusters on the Space Shuttle.
He also reported seeing sparks like a fire when using gasoline or carbon fuel.
Co-pilot Tamefuji described the lights as “Christmas assorted” lights with a “salmon” color. He said: I remember red or orange, and white landing light, just like a landing light. And weak green, ah, blinking. He also described the lights as pulsating slowly. They became stronger, became weaker., became stronger, became weaker, different from strobe lights.
The lights were “swinging” in unison as if there were “very good formation flight… close” of two aircraft side by side.
He described the appearance of the lights as similar to seeing “night flight head-on traffic,” where it is only possible to see the lights on an approaching aircraft and “we cannot see the total shape.”
He said, I’m sure I saw something. It was clear enough to make me believe that there was an oncoming aircraft.
Flight engineer Tsukuba, who sat behind the copilot, did not have as good a view of the lights. He first saw them “through the L1 window at the 11 o’clock position,” and he saw “clusters of lights undulating.”
These clusters were “made of two parts… shaped like windows of an airplane.”
He emphasized that “the lights in front of us were different from town lights.”
He described the colors as white or amber.
Tamefuji decided to call Anchorage Air Traffic Control, and for the next thirty minutes the 747 and AARTCC were in constant contact regarding the UFO.
During this time, Captain Terauchi asked Tskububa to hand him a camera so that he could attempt to take a photograph of the lights. However, Terauchi was unfamiliar with the camera and could not get it to operate. Tsukuba also could not get his camera to operate due to problems with the auto-focus and finally gave up trying to take a photo.
At this point they began experiencing some radio interference and were asked by Anchorage to change frequencies. Terauchi later said that Anchorage kept asking him about clouds in the immediate area:
They asked us several times if there were clouds near our altitude. We saw thin and spotty clouds near the mountain below us, no clouds in mid-to-upper air, and the air current was steady.
Soon after the exchanges about clouds, the objects flew off to the left. Terauchi said later: “There was a pale white flat light in the direction where the ships flew away, moving in a line along with us, in the same direction and same speed and at the same altitude as we were.”
Terauchi decided to see whether they could see anything on the 747’s own radar:
“I thought it would be impossible to find anything on an aircraft radar if a large ground radar did not show anything, but I judged the distance of the object visually and it was not very far.
“I set the digital weather radar distance to 20 (nautical) miles, radar angle to horizon (i.e., no depression angle). There it was on the screen. A large green and round object had appeared at 7 or 8 miles (13 km to 15 km) away, where the direction of the object was.
” We reported to Anchorage center that our radar caught the object within 7 or 8 miles in the 10 o’clock position. We asked them if they could catch it on ground radar, but it did not seem they could catch it at all.”
At 5:25:45, after spending two minutes looking, the military radar at Elmendorf Regional Operational Control Center also picked up something. The ROCC radar controller reported back to the AARTCC that he was getting some “surge primary return.” By this he meant an occasional radar echo unaccompanied by a transponder signal.
As the 747 neared Fairbanks:
“The lights (of the city) were extremely bright to eyes that were used to the dark. (The cockpit lights had been turned off to eliminate window reflections of internal lights.) We were just above the bright city lights and we checked the pale white light behind us.
” Alas! There was a silhouette of a gigantic spaceship.
“We must run away quickly! Anchorage Center.”
The JAL1628 is requesting a change of course to right 45 degrees.” It felt like a long time before we received permission.”
Just after the plane turned to the right, the AARTCC controller called the Fairbanks Approach Radar controller to find out whether or not the short-range radar had a target near the JAL. The approach radar reported no target other than JAL1628.
The plane came out of the turn and flew toward Talkeetna at an altitude of 31,000 ft, with the object still following.
At about 5:40, a United Airlines passenger jet took off from Anchorage and headed north to Fairbanks. The AARTCC controller decided to ask the UA pilot to try to see the object that was following the JAL flight.
The UA pilot said he would look when he got closer. The controller asked the JAL flight to stay at 31,000 ft, and the UA flight to stay at 29,000 ft. He then directed the UA flight to turn some more so that the planes would pass within five miles of one another.
As the United Airlines jet got closer, the UFO apparently dropped behind, allowing the JAL plane to get far ahead. The United pilot asked the AARTCC to have the JAL pilot flash the headlights on the JAL aircraft so he could locate the plane.
At 5:49:45 the JAL pilot did that. At this point the planes were about 25 miles apart.
When the planes were about 12 miles apart, the UA plane reported seeing the JAL plane and nothing else. But by this time the UFO had apparently disappeared, not being seen by JAL1628, either.
At about 5:51, the AARTCC requested that a military TOTEM flight in the area also fly toward the JAL plane for a look. During the next several minutes TOTEM viewed the JAL plane, but couldn’t see any other traffic. JAL1628 proceeded to Anchorage and landed at 6:20 PM. NOTE: The above image is CGI.

Strange Discoveries on Mars Really Do Deserve An Explanation... It's Littered with Anomalies!
Since man first saw Mars through telescopes they have pondered strange formations. In more modern times with the aid of satellite probes we have managed to get much more clarity of images, but this caused even further strange things to be found. Was Mars once occupied and what is scattered all across its surface?

NASA cuts live feed after showing alleged Black Knight Satellite
NASA cuts live feed after showing alleged Black Knight Satellite
Yesterday, NASA and Elon Musk's SpaceX were forced to abort theirFalcon 9 rocket launchjust 16 minutes before the planned blast off, because of looming tropical storms near Kennedy Space Center in Cape Canaveral, Florida.
But was the SpaceX Dragon aborted due to bad weather conditions? According to Florida Maquis, the thunderstorms ended in the early evening, and the weather actually cleared up a short time after the mission was aborted.
Indeed the launch was aborted because of weather issues and it would have been fixed in 10 minutes, but the lift off could not wait, because the fast-changing position of the ISS meant the rocket would have missed the target even leaving just seconds after the scheduled launch.
Nevertheless, Florida Maquis goes on and states that he noticed on the live feed, a strange anomaly near the International Space Station and suggested that maybe NASA aborted the launch due to this unidentified object speculating that it could have been the Black Knight Satellite.
When zooming in onto the black object we see that it is not just a speck on the lens, it clearly has a triangular shape but if it could have been the Black Knight Satellite is hard to say.
At the end of April, the artificial intelligence development firm OpenAI released a new neural net, Jukebox, which can create mashups and original music in the style of over 9,000 bands and musicians.
Alongside it, OpenAI released a list of sample tracks generated with the algorithm that bend music into new genres or even reinterpret one artist’s song in another’s style — think a jazz-pop hybrid of Ella Fitzgerald and Céline Dion.
It’s an incredible feat of technology, but Futurism’s editorial team was unsatisfied with the tracks OpenAI shared. To really kick the tires, we went to CJ Carr and Zack Zukowski, the musicians and computer science experts behind the algorithmically-generatedmusic group DADABOTS, with a request: We wanted to hear Frank Sinatra sing Britney Spears’ “Toxic.”
And boy, they delivered.
An algorithm that can create original works of music in the style of existing bands and artists raises unexplored legal and creative questions. For instance, can the artists that Jukebox was trained on claim credit for the resulting tracks? Or are we experiencing the beginning of a brand-new era of music?
“There’s so much creativity to explore there,” Zukowski told Futurism.
Below is the resulting song, in all its AI-generated glory, followed by Futurism’s lightly-edited conversation with algorithmic musicians Carr and Zukowski.
Futurism: Thanks for taking the time to chat, CJ and Zack. Before we jump in, I’d love to learn a little bit more about both of you, and how you learned how to do all this. What sort of background do you have that lent itself to AI-generated music?
Zack Zukowski: I think we’re both pretty much musicians first, but also I’ve been involved in tech for quite a while. I approached my machine learning studies from an audio perspective: I wanted to extend what was already being doing with synthesis and music technology. It seemed like machine learning was obviously the path that was going to make the most gains, so I started learning about those types of algorithms. SampleRNN is the tool we most like to use — that’s one of our main tools that we’ve been using for our livestreams and our Bandcamp albums over the last couple years.
CJ Carr: Musician first, motivated in computer science to do new things with music. DADABOTS itself comes out of hackathon culture. I’ve done 65 hackathons, and Zack and I together have won 15 or so. That environment inspires people to push what they’re doing in some new way, to do something provocative. That’s the spirit DADABOTS came out of in 2012, and we’ve been pushing it further and further as the tech has progressed.
Why did you make the decision to step up from individual hackathons and stick with DADABOTS? Where did the idea come from for your various projects?
CJ: When we started it, we were both interns at Berklee College of Music working in music tech. When I met Zack — for some reason it felt like I’ve known Zack my whole life. It was a natural collaboration. Zack knew more about signal processing than I did, I knew more about programming, and now we have both brains.
What’s your typical approach? What’s going on behind the scenes?
CJ: SampleRNN has been our main tool. It’s really fast to train — we can train it in a day or two on a new artist. One of the main things we love to do is collaborating with artists, when an artist says “hey I’d love to do a bot album.” But recently, Jukebox trumped the state of the art in music generation. They did a really good job.
SampleRNN and Jukebox, they’re similar in that they’re both sequence generators. It’s reading a sequence of audio at 44.1k or 16k sample rate, and then it’s trying to predict what the next sample is going to be. This net is making a decision at a fraction of a millisecond to come up with the next sample. This is why it’s called neural synthesis. It’s not copying and pasting audio from the training data, it’s learning to synthesize.
What’s different about them is that SampleRNN uses “Long Short Term Memory” (LSTM) architecture, whereas the jukebox uses a transformer architecture. The transformer has attention. This is a relatively new thing that’s come to popularity in deep learning, after RNN, after LSTM. It especially took over for language models. I don’t know if you remember fake news generators like GPT-2 and Grover. They use transformer architecture. Many of the language researchers left LSTM behind. No one had really applied it to audio music yet — that’s the big enhancement for Jukebox. They’re taking a language architecture and applying it to music.
They’re also doing this extra thing, called a “Vector-Quantized Variational AutoEncoder” (VQ-VAE). They’re trying to turn audio into language. They train a model that creates a codebook, like an alphabet. And they take this alphabet, which is a discrete set of 2048 symbols — each symbol is something about music — and then they train their transformer models on it.”
What does that alphabet look like? What is that “something about music?”
CJ: They didn’t do that analysis at all. We’re really curious. For instance, can we compose with it?
Zack: we have these 2048 characters, and so we wonder which ones are commonly used. Like in the alphabet we don’t use Zs too much. But what are the “vowels?” Which symbols are used frequently? It would be really interesting to see what happens when you start getting rid of some of these symbols and see what the net can do with what remains. The way we have the language of music theory with chords and scales, maybe this is something that we can compose with beyond making deepfakes of an artist.
What can that language tell us about the underlying rules and components of music, and how can we use these as building blocks themselves? They’re much higher-level than chords — maybe they’re genre-related. We really don’t know. It would be really cool to do that analysis and see what happens by using just a subset of the language.
CJ: They’ve come up with a new music theory.
Well, it sounds like the three of us have a lot of the same questions about all this. Have you started tinkering with it to learn what’s going on?
CJ: We’ve just got the code running. The first example is this Sinatra thing. But as we use this more, the philosophical implications here are that as musicians, we know intuitively that music is very language-like. It’s not just waves and noise, which is what it looks like at a small scale, but when we’re playing we’re communicating with each other. The bass and the drummer are in step, strings and vocals can be doing call-and-response. And OpenAI was just like “Hey, what if we treated music like language?”
If the sort of alphabet this algorithm uses could be seen as a new music theory, do you think this will be a tool for you two going forward? Or is it more of an oddity to play around with?
CJ: Maybe I should correct myself. Instead of being a music theory, these models can train music theory.
Zack: The theory isn’t something that we can explain right now. We can’t say “This value means this.” It’s not quite as human interpretable, I guess.
CJ: the model just learns probabilistic patterns, and that’s what music theory is. It’s these notes tend to have these patterns and produce these feelings. And those were human-invented. What if we just have a machine try to discover that on its own, and then we ask it to make music? And if it’s good at it, probably it’s learned a good quote-unquote “music theory.”
Zack: An analogy we thought of: Back in the days of Bach, and these composers who were really interested in having counterpoint — many voices moving in their own direction — they had a set of rules for this. The first melodic line the composer builds off is called cantus firmus. There was an educational game new composers would play — if you could follow the notes that were presented in the cantus firmus and guess what harmonizing notes were next, you’d be correct based on the music of the day.
We’re thinking this is kind of the machine version of that, in some ways. Something that can be used to make new music in the style of music that has been heard before.
I know it’s early days and that this is speculative, but do you have any predictions for how people might use Jukebox? Will it be more of these mashups, or do you think people will develop original compositions?
CJ: On the one hand, you have the fear of push-button art. A lot of people think push-button art is very grotesque. But I think push-button art, when a culture can achieve this — it’s a transcendent moment for that culture. It means the communication of that culture has achieved its capacity. Think about meme generators — I can take a picture of Keanu Reeves, put in some inside joke and send it to my friends, and then they can understand and appreciate what I’m communicating. That’s powerful. So it is grotesque, but it’s effectual.
On the other side, you’ll have these virtuosos — these creators — who are gonna do overkill and try to create a medium of art that’s never existed before. What interests us are these 24/7 generators, where it can just keep generating forever.
Zack: I think it’s an interesting tool for artists who have worked on a body of albums. There are artists who don’t even know they can be generated on Jukebox. So, I think many of them would like to know what can be generated in their likeness. It can be a variation tool, it can recreate work for an artist through a perspective they haven’t even heard. It can bend their work through similar artists or even very distantly-stylized artists. It can be a great training tool for artists.
You said you’d heard from some artists who approached you to generate music already — is that something you can talk about?
CJ: When bands approach us, they’ve mostly been staying within the lane of “Hey, use just my training data and let’s see what comes out — I’m really interested.”
Fans though, on YouTube, are like “Here’s a list of my four favorite bands, please make me something out of it.”
So, let’s talk about the actual track you made for us. For this new song, Futurism suggested Britney Spears’ “Toxic” as sung by Frank Sinatra. Did the technical side of pulling that together differ from your usual work?
CJ: This is different. With SampleRNN, we’re retraining it from scratch on usually one artist or one album. And that’s really where it shines — it’s not able to do these fusions very well. What OpenAI was able to do — with a giant multimillion-dollar compute budget — they were able to train these giant neural nets. And they trained them on over 9,000 artists in over 300 genres. You need a mega team with a huge budget just to make this generalizable net.
Zack: There are two options. There’s lyrics and no lyrics. No lyrics is sort of like how SampleRNN has worked. With lyrics it tries to get them all in order, but sometimes it loops or repeats. But it tries to go beginning to end and keep the flow going. If you have too many lyrics, it doesn’t understand. It doesn’t understand that if you have a chorus repeating, the music should repeat as well. So we find that these shorter compositions work better for us.
But you had lyrics in past projects that used SampleRNN, like “Human Extinction Party.” How did that differ?
CJ: That was smoke and mirrors.
Zack: That was kind of an illusion. The album we trained it on had vocals, so some made it through to. We had a text generator that made up lyrics whenever it heard a sound.
In a lot of these Jukebox mashups, I’ve noticed that the voice sounds sort of strained. Is that just a matter of the AI-generated voice being forced to hit a certain note, or does it have something more to do with the limitations of the algorithm itself?
Zack: Your guess sounds similar to what I’d say. It was probably just really unlikely that those lyrics or the phonemes, the sounds themselves of the words, showed up in a similar way to how we were forcing it to generate those syllables. It probably heard a lot more music that isn’t Frank Sinatra, so it can imagine some things that Frank Sinatra didn’t do. But it just comes down to being somewhat different from any of the original Frank Sinatra texts.
When you were creating this rendition of Toxic, did you hit any snags along the way? Or was it just a matter of giving the algorithm enough time to do its work?
CJ: Part of it is we need a really expensive piece of hardware that we need to rent on Amazon Cloud at three dollars per hour. And it takes — how long did it take to generate, Zack?
Zack: The final one I had generated took about a day, but I had been doing it over and over again for a week. You have so little control that sometimes you just gotta go again. It would get a few phrases and then it would lose track of the lyrics. Sometimes you’d get two lines but not the whole chorus in a row. It came down to luck — waiting for the right one to come along.
It could loop a line, or sometimes it could go into seemingly different songs. It would completely lose track of where it was. There are some pretty wild things that can happen. One time I was generating Frank Sinatra, and it was clearly a chorus of men and women together. It wasn’t even the right voice. It can get pretty ghostly.
Do you know if there are any legal issues involved in this kind of music? The capability to generate new music in the style or voice of an artist seems like uncharted territory, but are there issues with the mashups that use existing lyrics? Or are those more acceptable under the guise of fair use, sort of like parody songs?
CJ: We’re not legal people, we haven’t studied copyright issues. The vibe is that there’s a strong case for fair use, but artists may not like people creating these deepfakes.
Zack: I think it comes down to intention, and whatever the law decides they’ll decide. But as people using this tool, artists, there’s definitely a code of ethics that people should probably respect. Don’t piss people off. We try our best to cite the people who worked on the tech, the people who it was trained on. It all just depends how you’re putting it out and how respectful you’re being of people’s work.
Before I let you go, what else are you two working on right now?
CJ: Our long-term research is trying to make these models faster and cheaper so bedroom producers and 12-year-olds can be making music no one’s ever thought of. Of course, right now it’s very expensive and it takes days. We’re in a privileged position of being able to do it with the rented hardware.
Specifically, what we’re doing right now — there’s the list of 9,000-plus bands that the model currently supports. But what’s interesting is the bands weren’t asked to be a part of this dataset. Some machine learning researchers on Twitter were debating the ethics of that. There are two sides of that, of course, but we really want to reach out to those bands. If anyone knows these bands, if you are these bands, we will generate music for you. We want to take this technology, which we think is capable of brand-new forms of creativity, and give it back to artists.
Scientists studying the ancient Martian Tissint meteorite say they’ve found new evidence that Mars was volcanically active a few hundred million years ago … and may still be today.
Orbital view from Mars Express of Olympus Mons, the tallest volcano on Mars, stretching some 13.6 miles (22 km, 72,000 feet) above the red Martian plains. Olympus Mons is 2 1/2 times taller than Mount Everest!
Is Mars still volcanically active? At first glance, it wouldn’t seem to be, since no eruptions have ever been observed from any of the numerous volcanoes dotting its desert surface. Recent findings from NASA’s InSightlander have shown that there’s still at least some residual geologic activity underground, however, in the form of marsquakes. Now, a newly announced study of a Martian meteorite has provided the first evidence of what scientists call magma convection on Mars – a rising and falling of currents in molten material beneath Mars’ surface – that took place in the planet’s mantle a few hundred million years ago. Perhaps this slow roilingof magma beneath Mars’ crust still occurs today.
The new peer-reviewed findings were published in Meteoritics & Planetary Science on May 7, 2020.
The intriguing results – reported in ScienceAlert by Michelle Star on May 11, 2020 – come from a new study of the Tissint Martian meteorite. A Martian meteorite is a rock ejected from Mars, likely via an impact event, which traversed interplanetary space and ultimately landed on Earth. Found in Morocco on July 18, 2011, the Tissint meteorite originated from deep within Mars. Tissint has been the subject of much study already, but this time, the researchers found something surprising. The meteorite contained crystals of olivine, rock-forming minerals commonly found in Earth’s crust.
When those crystals were examined more closely, it was found that they could have only formed in changing temperatures within currents of magma convection.
Mars’ internal structure: core, mantle, crust and atmosphere.

The crystals are an estimated 674 to 582 million years old, fairly young geologically speaking, so the implication is that Mars was still volcanically active at that time. Planetary geologist Nicola Mari of the University of Glasgow toldScienceAlert:
There was no previous evidence of convection on Mars, but the question ‘Is Mars a still volcanically active planet?’ was previously investigated using different methods. However, this is the first study that proves activity in the Mars interior from a purely chemical point of view, on real Martian samples.
The olivine crystals would have formed inside a magma chamber deep underground. Olivine is common in Earth’s mantle, and even in meteorites. But the researchers noticed something odd about the olivine crystals in Tissint. They had irregularly-spaced bands composed of phosphorus. It’s a known process on Earth, called solute trapping, where, during rapid solidification, solute (the substance dissolved in a solution) may be incorporated into the solid phase at a concentration significantly different from that predicted by equilibrium thermodynamics.
This occurs when the rate of crystal growth exceeds the rate at which phosphorus can diffuse through the melt, thus the phosphorus is obliged to enter the crystal structure instead of ‘swimming’ in the liquid magma. In the magma chamber that generated the lava that I studied, the convection was so vigorous that the olivines were moved from the bottom of the chamber (hotter) to the top (cooler) very rapidly, to be precise, this likely generated cooling rates of 15-30 degrees Celsius per hour [about 27-55 degrees Fahrenheit] for the olivines.
From the paper:
The Tissint martian meteorite is an unusual depleted olivine-phyric shergottite, reportedly sourced from a mantle-derived melt within a deep magma chamber. Here, we report major and trace element data for Tissint olivine and pyroxene, and use these data to provide new insights into the dynamics of the Tissint magma chamber. The presence of irregularly spaced oscillatory phosphorous (P)-rich bands in olivine, along with geochemical evidence indicative of a closed magmatic system, implies that the olivine grains were subject to solute trapping caused by vigorous crystal convection within the Tissint magma chamber.
Calculated equilibration temperatures for the earliest crystallizing (antecrystic) olivine cores suggest a Tissint magma source temperature of 1680 degrees Celsius [3056 degrees Fahrenheit], and a local martian mantle temperature of 1560 degrees Celsius [2840 degrees F] during the Late Amazonian, the latter being consistent with the ambient mantle temperature of Archean Earth.
How do the researchers know the meteorite came originally from deep under Mars’ crust? The larger olivine crystals contained traces of nickel and cobalt. This, along with previous evidence, shows that the meteorite must have once been part of rock 25 to 50 miles (40 to 80 kilometers) beneath the surface.

With all of this data, the researchers could estimate the temperatures in the Martian mantle at the time when the crystals first formed. They came up with 1,560 degrees Celsius (2840 degrees F) during the Martian Late Amazonian period. That’s a lot hotter than had been previously thought, almost as hot as 1,650 degrees Celsius (3002 F) during the Archean Eon on Earth, 4 to 2.5 billion years ago. This is recent enough, geologically, to suggest that Mars may still have active magma convection even today. Mari said:
I really think that Mars could be a still volcanically active world today, and these new results point toward this. We may not see a volcanic eruption on Mars for the next 5 million years, but this doesn’t mean that the planet is inactive. It could just mean that the timing between eruptions between Mars and Earth is different, and instead of seeing one or more eruptions per day (as on Earth) we could see a Martian eruption every n-millions of years.
So Mars may still be volcanically active today – as in recent geological time – but eruptions are spaced far apart, by a few million years, according to the researchers. It would be amazing to see a volcanic eruption on Mars, since the planet’s largest volcanoes are much larger than ones on Earth. Olympus Mons, the biggest of them all, is taller than Mount Everest!
Nicola Mari of the University of Glasgow, lead author of the new study.
In 2014, it was reported that the Tissint meteorite might contain traces of ancient microbial activity. According to Philippe Gillet, director of École Polytechnique de Lausanne (EPFL, Switzerland) Earth and Planetary Sciences Laboratory:
Insisting on certainty is unwise, particularly on such a sensitive topic. I’m completely open to the possibility that other studies might contradict our findings. However, our conclusions are such that they will rekindle the debate as to the possible existence of biological activity on Mars – at least in the past. So far, there is no other theory that we find more compelling.
While the jury is still out on the possible life traces, Tissint has shown, at the very least, that Mars was once much more active geologically than it is now.
Bottom line: A new study of an ancient Martian meteorite suggests that Mars was more volcanically active a few hundred million years ago than previously thought, and may even still be active today.
A team of researchers from the Higher School of Economics University and Open University in Moscow, Russia claim they have demonstrated that an artificial intelligence can make accurate personality judgments based on selfies alone — more accurately than some humans.
The researchers suggest the technology could be used to help match people up in online dating services or help companies sell products that are tailored to individual personalities.
That’s apropos, because two co-authors listed on a paper about the research published today in Scientific Reports — a journal run by Nature — are affiliated with a Russian AI psychological profiling company called BestFitMe, which helps companies hire the right employees.
As detailed in the paper, the team asked 12,000 volunteers to complete a questionnaire that they used to build a database of personality traits. To go along with that data, the volunteers also uploaded a total of 31,000 selfies.
The questionnaire was based around the “Big Five” personality traits, five core traits that psychological researchers often use to describe subjects’ personalities, including openness to experience, conscientiousness, extroversion, agreeableness, and neuroticism.
After training a neural network on the dataset, the researchers found that it could accurately predict personality traits based on “real-life photographs taken in uncontrolled conditions,” as they write in their paper.
While accurate, the precision of their AI leaves something to be desired. They found that their AI “can can make a correct guess about the relative standing of two randomly chosen individuals on a personality dimension in 58% of cases.”
That result isn’t exactly groundbreaking — but it’s a little better than just guessing, which is vaguely impressive.
Strikingly, the researchers claim their AI is better at predicting the traits than humans. While rating personality traits by human “close relatives or colleagues” was far more accurate than when rated by strangers, they found that the AI “outperforms an average human rater who meets the target in person without any prior acquaintance,” according to the paper.
Considering the woeful accuracy, and the fact that some of the authors listed on the study are working on commercializing similar tech, these results should be taken with a hefty grain of salt.
Neural networks have generated some impressive results, but any research that draws self-serving conclusions — especially when they require some statistical gymnastics — should be treated with scrutiny.
Mammatus clouds may seem ominous. But they have a magnificent beauty of their own.

Mammatus clouds are pouch-like protrusions hanging from the undersides of clouds, usually thunderstorm anvil clouds but other types of clouds as well. Composed primarily of ice, these cloud pouches can extend hundreds of miles in any direction, remaining visible in your sky for perhaps 10 or 15 minutes at a time.
People associate them with severe weather, and it’s true they can appear around, before or after a storm. Contrary to myth, they don’t continue extending downward to form tornados, but they are interesting in part because they’re formed by sinking air. Most clouds are formed by rising air. Mammatus clouds can appear ominous. But, in a way that’s so common in nature, their dangerous aspect goes hand in hand with a magnificent beauty.

View at EarthSky Community Photos. | Peter Lowenstein captured these spectacular mammatus clouds in Mutare, Zimbabwe, on March 23, 2020. He wrote: “I took an early morning walk up to the Murambi High Level Water Tanks in the hope of catching a glimpse of the very thin old moon rising. Instead there was a surprise appearance of mammatus clouds on the underside of a sunrise-illuminated band of altostratus cloud above.”
Stephanie Tilden Dorr in Wichita, Kansas, caught these clouds in June 2018. She wrote: “Mammatus clouds appearing exactly one hour after a hailstorm passed over. Twenty-five years in Kansas and I’ve only seen mammatus clouds this vivid one other time, years ago. So exciting!”
