I touched a UFO: ex-air force pilot
I touched a UFO: ex-air force pilot
A group of former pilots who have recounted seeing strange phenomena in the sky has demanded the US government reopen an investigation into UFOs.
Several pilots offered dramatic accounts of witnessing UFOs - including a transparent flying disc and a triangular craft with mysterious markings - as they insisted their questions needed to be taken seriously more than 30 years after the US file was closed.
"We want the US government to stop perpetuating the myth that all UFOs can be explained away in down-to-earth, conventional terms," said Fife Symington, former governor of Arizona and air force pilot who says he saw a UFO in 1997.
"Instead our country needs to reopen its official investigation that it shut down in 1969,"Symington said.
"We believe that for reasons of both national security and flight safety, every country should make an effort to identify any object in its airspace," said a statement from the 19 former pilots and government officials from around the world.
The subject of UFOs came up in a recent debate among US presidential candidates, with Democrat Dennis Kucinich saying he once saw a UFO - making him the object of ridicule and jokes by late night television comedians.
Sceptics say UFO sightings are merely aircraft, satellites or meteors re-entering the Earth's atmosphere.
But the retired pilots spoke to a sympathetic audience of UFO "believers" who heard them recall their encounters with seemingly other-worldly objects appearing out of the sky.
"Nothing in my training prepared me for what we were witnessing," said James Penniston, a retired US Air Force pilot, as he described seeing and touching a UFO when he was stationed at a British air base in Woodbridge.
He said he saw an inexplicable triangular craft in a clearing in the woods with "blue and yellow lights swirling around the exterior".
The UFO was "warm to the touch and felt like metal," Penniston said. One side of the craft had pictorial symbols and "the largest symbol was a triangle, which was centred in the middle of the others," he said.
Then after 45 minutes the light from the object "began to intensify" and it then "shot off at an unbelievable speed" before 80 Air Force personnel, he said. "In my logbook, I wrote 'speed: impossible'."
Rodrigo Bravo from Chile's air force said UFOs needed to be studied but lamented that the media often belittle the sightings.
"Sadly the UFO subject has been contaminated with false information, out of touch with reality, provided by unqualified people to the media," Bravo said.
"One of our most important civil aviation cases occurred in 1988, showing that unidentified flying objects can be a danger for air operations," he said.
"A Boeing 737 pilot on a final approach to the runway at the Puerto Montt airport suddenly encountered a large white light surrounded by green and red."
The pilot took a sharp turn to avoid a collision, according to Bravo.
The panel included a former Iranian fighter pilot, Parviz Jafari, who said in 1976 he tried in vain to fire from his jet at an "object which was flashing with intense red, green, orange and blue light" over Tehran.
But when he approached, "my weapons jammed and my radio communications garbled".
A former Air France captain, Jean-Charles Duboc, said in 1994 he and his crew saw "a huge flying disc" near Paris with a diameter of about 300 metres that left no sign on radar.
The disc "became transparent and disappeared in about 10 to 20 seconds," Duboc said.
The former pilot said like other major airlines Air France was mindful of its image and it was difficult to raise the subject of UFOs.
A former official with the Federal Aviation Administration, John Callahan, said government agencies discourage inquiries into UFOs.
"'Who believes in UFOs?' is the kind of attitude of the FAA all the time," he said.
"However, when I asked the CIA person: 'What do you think it was,' he responded 'a UFO'."
When Callahan suggested the government tell Americans about a UFO, the CIA official allegedly told him: "'No way, if we were to tell the American public there are UFOs they would panic."'

NASA schakelt weer livestream uit nadat UFO bij het ISS verschijnt
Op de livestream van de Amerikaanse ruimtevaartorganisatie NASA is een mysterieus object gezien bij het internationale ruimtestation ISS. Sommige alien-jagers zeggen dat het een UFO is.
John Craddick uit het Engelse Wolverhampton vertelde aan de Daily Mirror dat hij vaak naar de livestream van het ISS kijkt, maar er nog nooit UFO’s op heeft gespot.
“Ik liet een vriend zien hoe het werkte, toen het beeld plotseling op zwart ging,” zei hij. “Toen het beeld weer terug was, verscheen dit object.”
Steeds groter
“Het was eerst klein en werd steeds groter,” vervolgde hij. “Het was ongeveer 25 seconden te zien.”
UFO-expert Nigel Watson vertelde aan de Daily Mail dat UFO’s bij het ISS vaak reflecties zijn.
“Veel UFO’s die worden vastgelegd door de camera’s van het ISS kunnen worden verklaard als beelden van ruimtepuin of satellieten in de verte,” zei hij.
Vlekje
“Zelfs kleine deeltjes kunnen eruitzien als UFO’s als ze worden beschenen door het licht van de zon,” ging hij verder.
NASA heeft nog niet gereageerd op de waarneming die Craddick heeft gedaan.
In november 2016 gingen beelden rond van een vlekje bij het ISS waarna de NASA de livestream uitschakelde.
Bewust
Complottheoretici concludeerden dat het object een buitenaards ruimteschip was en suggereerden dat NASA dit soort informatie bewust achterhoudt.
Volgens de ruimtevaartorganisatie komt het soms voor dat de verbinding tussen het ISS ende aarde wordt verbroken.
James Cameron links find of bronze-age anchors to lost city of Atlantis
James Cameron links find of bronze-age anchors to lost city of Atlantis
Jamie SeidelNews Corp Australia Network
TITANIC director James Cameron thinks he’s found Atlantis. His documentary team has stumbled upon a cluster of six 4000-year-old anchors just outside the entrance to the Mediterranean.
Myth? History? Or just a good storytelling opportunity?
The idea of an advanced ancient civilisation lost to history certainly has eternal appeal.
It’s certainly been a favoured subject among documentary makers.
Now Oscar-winner James Cameron joins them.
His National Geographic series Atlantis Rising goes to air in the United States this weekend.
Suitably, he’s got a tantalising find to pin his narrative upon.
The mystical nature of Atlantis has made it a popular subject of books, television and and movies.

MEGA-MYTH
Is there more to Atlantis than just an ancient fireside tale?
The idea exploded among the modern popular imagination with pseudoscientific books such as Erich von Daniken’s Chariots of the Gods in 1968 and, more recently, the likes of Fingerprints of the Gods by Graham Hancock.
Atlantis has been linked to just about everything: The pyramids were really an astral power station to charge its technology. Its survivors seeded just about every ancient civilisation. It was buried under Antarctica’s ice (or off the Bahamas, or Japan, or just about any mysterious place).
There are more plausible, though equally unproven, theories.
It could be a distorted memory of the Black Sea Flood which saw a vast swath of Europe engulfed about 5600BC. Or a memory the Minoan palace vaporised on the island of Santorini erupted, sending tsunamis through the Eastern Mediterranean at some point around 1600BC.
That last one looks particularly enticing.
But the fact remains all we really have is a few throwaway lines included in two moral tales written by the Greek philosopher Plato. Most academics feel this was likely to have been an allegorical warning to the then vibrant city-state of Athens not to turn its back on the gods.

CAMERON’S TWIST
Oceanic explorer Robert Ballard beat Cameron to the Titanic in 1985. Now Cameron’s attempting to go one better.
“We set out to investigate the most interesting theories that argue that there is some kind of history behind the myth of Atlantis,” Cameron says.
Expedition leader Richard Freund (an archaeologist from the University of Hartford) is more ebullent: “This is the world’s most sophisticated and extensive search ever made.”
The plot sounds familiar.
It’s the most “sophisticated and extensive search ever made”. They use ‘cutting edge technology’ to explore a ‘virtual map’ built from Plato’s ancient writings.
While the show travels throughout Greece, the Mediterranean and the Atlantic Ocean tracking ‘sightings’ of Atlantis, much is made of the discovery of a cluster of Bronze Age anchors on the Atlantic side of the Strait of Gibraltar — which some believe to be the “Pillars of Hercules’ Plato states the civilisation was ‘beyond’.
“These anchors could be 3500 to 4000 years old and establish a harbour in the Atlantic, where I didn’t even dare dream to find anchors,” filmmaker Simcha Jacobovici said in a statement. “It’s easier to find a needle in a haystack than Bronze Age anchors in the Atlantic.”
The fun part will be linking them to Plato’s 4th Century BC writings.
The ancient Minoan civilisation, based on Crete, was an advanced race of ocean-going traders. Snake and bull worshipping goddesses feature prominently among their art.

ANCHORED IN REALITY?
A map of ancient Santorini found on the wall of a ruined Minoan building, buried deep under volcanic ash.Source:Supplied
Plato mentions Atlantis in his works ‘Temaeus’ and ‘Critas’, but provides only an outline sketch of this mysterious civilisation.
He describes it as an island, formed of concentric rings. At its heart was a great city. It’s inhabitants were half-god and half-human. They were rich in resources and mysterious metals. They were proficient seagoers.
The story goes that, through their greed, they upset the great god fo the sea Poseidon. So he got rid of them through enormous earthquakes and floods.
There is one historic event that fits Plato’s tale remarkably well.
It’s the story of the eruption of the volcano Thera (now called Santorini) in 1650BC.
Archaeologists in recent decades have uncovered the remains of an ancient settlement there belonging to the then remarkably advanced Minoan civilisation.
Among the ruins they found a map. It shows a palace on an island in the middle of volcanic caldera.
The fallout of the eruption, and its subsequent tsunamis, are believed to have triggered the collapse of the entire civilisation as it engulfed much of northern Crete.
Into the ruins marched tribes of Greeks - the predecessors of the great nations of Sparta, Corinth and Athens.
So the idea that the disaster that destroyed the Minoans may have somehow wound its way through the centuries down to Plato certainly seems enticing. Though unsubstantiated.

Date of discovery: January 27, 2017 Location of discovery: Turks And Caicos Islands Google Earth Coordinates: 21°43'44.66"N 71°48'59.23"W Hey, this new HP Pavillion computer really kiss @#$. Love it, thanks 54. Google Earth works smoothly with it. Found this with it today. I found an entrance to an underground base. There is a large circular entrance that goes deep below the ground on the island of Turks and Caicos. Not far from Cuba. The hole is huge! I mean its 500+ meters across, big enough for the US military to build a submarine base down there. This is massive. Now, think of the most isolated place on Earth that could hide an alien base. Are you thinking the ocean...good job, and maybe a isolated small island in the middle of nowhere...great work. Here it is. The alien base entrance that alien don't want you to know about. Scott C.

Black UFO Hides Over Clouds Caught By NASA Space Station Cam, Jan 27, 2017, UFO Sighting Daily.
Date of sighting: January 27, 2017 Location of sighting: NASA/Russia Space Station, ISS I was watching the live cam and was a bit irritated that they were going to blue screen and glitch screen about 65% of the time this week. Either they are trying to hide UFOs or they are causing their own glitches so they can finally shut down their spy cameras to the public. Yes, the two new cams which the public are not allowed to use can read a license plate of a car anywhere on the planet. A dark object passed on the clouds below the space station. The object has openings and was very black, making it easy to spot on top of the white clouds. Its non reflective black, much like a lot of the structures I have found on Earths moon. That is where the USAF got their stealth materials, alien tech. Scott C. Waring

UFO Lights Filmed Over Goodyear, Arizona – January 2017, Video, UFO Sighting News.
Date of sighting: January 2017
Location of sighting: Goodyear, Arizona, USA
A lot of skeptics would say that the lights are on the mountain top. So I added some light to the above photo so you can clearly see, the lights are far above the mountains. The are lined up, as if military formation to watch out for one another. Probably UFOs from the Tall White base at Nellis AFB old firing range. Nice video byTheSkyUFO of Youtube.
Scott C. Waring
Eyewitness states:
My daughter and I were driving at night in the dark when we noticed 4 lights that looked very bright above the distant mountains. Four of them lined up next to one another from right to left. They stayed stationary for a few moments and then 1 would fly swiftly away from the others leaving 3 in a linear horizontal line before it disappeared. It would spontaneously reappear and then fly above the other 3, move left again and then realign with the other 4 leaving 4 brightly shining in the sky. We also saw a distant airplane but it appeared farther away, higher and with blinking lights. The UFOS we saw were solid bright white/yellow and were brilliant against the night sky. They flew fluidly, and would move great lengths across the sky in an instant, disappearing and reappearing. They were much larger than stars in the sky and brighter than the brightest star. We felt excited and in awe, and happy they would reappear so we could get good pictures and videos. Our neighbors also saw them while out driving. We finally left to go home. We have seen them before in a dark night sky over the Estrella mountains to the East. They are common in this part of Goodyear. We see them several times a year.

Date of sighting: January 26, 2017 Location of sighting: Mexican Boarder Here is a mind-blowing video from Tyler of SecureTeam10. He got hold of a video of a fleet of glowing UFOs during the day over Mexico. And Just in time too, because the original was deleted by either its source or government hackers. That happens a lot more than you know. If Tyler hadn't saved this video for us, it would have been lost forever, so click here to subscribe to his Channel and stay up to date on the latest sightings. Mexico is a hotbed of UFO activity and there are a lot of things in the sky their daily, that the world governments don't want you to see. Its just amazing to watch this video as traffic almost comes to a stop. You can hear the angry people honking their horns and guys pointing their cameras to the sky. Awesome raw footage. Scott C.

U.S. Navy Photo Showing UFO Landing On Aircraft Carrier Is Genuine, Claims Retired Aerospace Engineer
U.S. Navy Photo Showing UFO Landing On Aircraft Carrier Is Genuine, Claims Retired Aerospace Engineer
Retired aerospace engineer William Tompkins said a photograph showing a flying saucer that is apparently landing on the aircraft carrier’s flight deck is genuine. Tompkins, who had served leading U.S. corporations for four decades up until 1984, discussed the photo on May 4 in a radio interview. He stressed that the picture was taken from one of the landings by friendly Nordic extraterrestrial UFOs, which were considered regular incidents on U.S. Navy aircraft carriers.
Tompkins career started in 1942 as a Naval Intelligence operative. His duties include giving intelligence briefings to select U.S. aerospace corporations on Nazi Germany’s secret development of anti-gravity spacecraft. To support his claims, he supplied multiple documents as proofs he was assigned to such secret operation and operated out of Naval Air Station in San Diego.
Tompkins said that the extraterrestrial craft would land to get the admiral of the naval battle group and bring him to the mothership in space to hold meetings with commanders of a Nordic Space Navy.
Tomkins explained that the alien craft would go down to talk to the admiral in command on a particular battle group. They would then conduct other programs and meetings. The admiral, together with some other people, would get into the extraterrestrial craft to go to the alien mothership. These aliens, of course, brought them back later, according to Tompkins. Tompkins further emphasized during the interview that the UFOs landed on their aircraft carriers many times.
Frank Chille, the one who got the photo, shared the story about it. He said the original photograph that shows the disk landing on the aircraft carrier was shown to him by Graham Bethune over 15 years ago. The photo was on thick paper and the back side it said “U.S. Navy, top secret, eyes only, 1955.” Chille stated that Bethune allowed him to make a copy of it.

Apparent Fleet OF UFOs Photographed Over Telecoms Towers In Mexico
Apparent Fleet OF UFOs Photographed Over Telecoms Towers In Mexico
Claims of space aliens intercepting human messages have sparked after a stunning image of apparent green and blue UFOs over a telecommunications tower made the rounds online.
The picture of the towers in Mexico was snapped on May 2, 2006, but only recently made some noise after it was submitted to the Mutual UFO Network (MUFON) for expert analysis.
The unnamed photographer said he was about 800 meters away from the telecommunications towers when he snapped the photo with a long exposure. He claimed that he took other rounds of pictures of the same towers in similar conditions three weeks later, but nothing unusual appeared in them.
Some observers say that it is just lens flares, which typically appear when a camera pointed at bright artificial lights or sunlight that refracts inside the lens, and the light reflection then appears on the printed image.
However, others conclude that these were alien craft wanting to intercept data from the telecommunications towers. They say that one photograph actually shows four glowing green disks recording data and information from those towers. They speculate that the so-called lens flares do not appear in other pictures because the aliens already realized that they had been seen. They further explain that powerful lights below, which some of them contain infrared lights, reveal the UFOs to the camera for a few moments until the aliens altered the shield harmonics to hide them.
Some residents in Austin want to know if a UFO visited their area on Monday night after they recorded a video of a strange airborne object. It appears that they are not alone as many others reported seeing something mysterious in the sky over Texas.
Witness Rachel Jensen believes they are UFOs giving an impressive show in the sky over East Austin. Jensen says that by the time they arrived, they just went up and took off at a tremendous speed.
On Monday night, her roommate saw three lights in a triangle formation coming at him. He then called Jensen outside to check the fantastic aerial event.
Just when Jensen stepped out, she looked to the sky and noticed the triangle that just separated into three. She says there was one object in front and two others behind it. Jensen describes them as bright orange, glowing, and almost fiery.
At one point the two witnesses saw another light. They say it was moving back-and-forth erratically. Jensen grabbed her phone and captured as much of the mysterious light on camera. After the unusual event, she called Austin 311 to report it.
On the same night, the American Meteor Society also got sighting reports of a fireball over Louisiana and Texas from at least five people.
Meanwhile, Austin Photographer Christopher Sherman captured a stunning photo showing Downtown Austin, but looking closely at it, a long curved light-streak passing through the tree can be seen, and another smaller streak to the left is also visible. The picture was also snapped around the same time Jensen saw strange lights in the sky.
Ooit werd de aarde door een heel andere mix van meteorieten bekogeld
Ooit werd de aarde door een heel andere mix van meteorieten bekogeld

De meteorieten die we nu als zeldzaam bestempelen, landden meer dan 466 miljoen jaar geleden regelmatig op aarde.
Tot die conclusie komen onderzoekers in het blad Nature Astronomy. Het is verrassend. Aangenomen werd namelijk dat het zonnestelsel de afgelopen 500 miljoen jaar vrij stabiel was. “Dus het is verrassend dat de meteorietenstroom zo’n 467 miljoen jaar geleden zo anders was dan nu,” vindt onderzoeker Birger Schmitz.
466 miljoen jaar geleden Meteorieten zijn stenen die vanuit de ruimte op aarde vallen. De stenen komen vrij tijdens botsingen tussen planetoïden, manen en zelfs planeten en vormen een afspiegeling van de samenstelling van deze hemellichamen. Zo’n 466 miljoen jaar geleden vond er op grote afstand van de aarde een enorme botsing plaats. Een object sloeg in op een planetoïde die vervolgens uit elkaar spatte. Brokstukken van die planetoïde vallen sindsdien richting de aarde.
Micrometeorieten Maar hoe zagen de meteorieten die vóór die grote botsing plaatsvond op aarde terechtkwamen, eruit? Daarvoor moet je eigenlijk kijken naar meteorieten die meer dan 466 miljoen jaar geleden op aarde landden. Maar dergelijke meteorieten worden niet vaak teruggevonden. Daarom richtten onderzoekers zich in hun studie op micro-meteorieten – kleine stukjes steen (met een diameter kleiner dan 2 millimeter) – die voor die tijd op aarde terechtkwamen. Dergelijke micro-meteorieten zijn wat minder zeldzaam.
Vesta Uit een analyse van die micro-meteorieten blijkt dat deze heel anders waren dan de meteorieten die vandaag de dag op aarde landen. Maar liefst 34 procent van de onderzochte meteorieten die meer dan 466 miljoen jaar geleden op aarde landden, behoorden tot de zogenoemde ‘primitieve achondrieten’. Ter vergelijking: slechts 0,45 procent van de meteorieten die vandaag de dag op aarde landen, behoren tot dit type. Weer andere, oude micrometeorieten bleken resten van Vesta te zijn: de helderste planetoïde die ook vanaf de aarde zichtbaar is en meer dan een miljard jaar geleden een botsing meemaakte.
“We ontdekten dat de meteorietenstroom en de variatie aan meteorieten die op aarde vielen, heel, heel anders was dan vandaag de dag,” concludeert onderzoeker Philipp Heck. “Wanneer je naar de meteorieten kijkt die de afgelopen 100 miljoen jaar op aarde zijn gevallen, krijg je geen compleet beeld.” Onderzoeker William Bottke legt uit: “Het bestuderen van meteorieten die vanuit de planetoïdengordel op aarde worden afgeleverd kun je vergelijken met het bestuderen van aardverschuivingen die op verschillende momenten op de helling van een berg ontstaan. De stenen die je vandaag de dag aan de voet van de berg vindt, komen voornamelijk voort uit een aantal recente aardverschuivingen. Ga je verder terug in de tijd dan zijn oudere landverschuivingen belangrijker. Hetzelfde geldt voor planetoïden die uiteen zijn gevallen: jongere exemplaren domineren de huidige meteorietenstroom, terwijl in het verleden de oudere exemplaren domineerden.” Meer inzicht in die verschillende meteorietenstromen is belangrijk, benadrukt Heck. “Meer weten over de verschillende soorten meteorieten die door de tijd heen zijn gevallen, geeft ons meer inzicht in de evolutie van de planetoïdengordel en de wijze waarop verschillende botsingen ontstonden.”

Scientists: There is a Mirror Universe where Time moves backwards
Scientists: There is a Mirror Universe where Time moves backwards
Time as we know it is something extremely complex that according to many researchers around to globe, isn’t fully understood. We, humans, experience time in one direction meaning that we all get older, we remember our past but we cannot look at the future. However, nothing in the known laws of physics tells us that time MUST move forward.
Among other theories, some suggest the Big Bang was not the beginning of the universe and that we may be living in the past of a parallel universe.
In order to try and solve the biggest mystery of all, two separate groups of prominent scientists are creating models that are able to examine the initial conditions in the universe that might have created what we call ‘arrow of time’. Interestingly, both groups seem to show time moving in two different directions, a contradictory finding according to many researchers around the globe.
Scientists believe that when the Big Bang created our universe, it also created a second ‘mirror universe’ where time actually moves in the opposite direction. Looking at it from our perspective, time in the parallel universe moves backwards. However, ‘anyone’ inside the parallel universe would perceive our universe’s time as if it were moving backwards:
The first model which was published over a year ago in Physical Review Letters tells us that one of the most basic implications proposed in Newton’s theory of gravity creates the necessary conditions for time as we know it to move in a certain direction.
According to Julian Barbour from the University of Oxford, Tim Koslowski from the University of New Brunswick and Flavio Mercati from the Perimeter Institute for Theoretical Physics, for any confined system of particles—a self-contained universe like the one we live for example—gravity creates a point when the distance between particles is reduced to a minimum. But, when the particles expand outwards, it occurs into different temporal directions, researchers argue.
According to quartz.com, Barbour and his colleagues created a simplified 1,000 particle point model of the universe showing this dual expansion, with gravity creating structure in both directions.
According to the Second Law of thermodynamics, systems like that converge and expand by necessity explains, Flavio Mercati.
According to researchers, the moment before the ‘expansion’ is referred to as the “Janus Point”.
In an interview with Quartz.com, Barbour explains “Time is not something that pre-exists.”
“The direction and flow of time we have to deduce from what’s happening in the universe. When we look at it that way, it’s natural to say that time begins at that central point and flows away in opposite directions.”
To simplify the explanations, Barbour compares the so-called Janus Point to the moment a river splits in two and flows in opposite directions.
“It’s the simplest thing,” he says. “You start at that central Janus point where the motion is chaotic –that’s like the Greek notion of primordial chaos—but then in both directions you get this structure forming. If the theory is right, then there’s another universe on the other side of the big bang in which the direction of experience of time is opposite to ours.”
While the above-mentioned theory isn’t accepted by all researchers, it did create excitement in the scientific community, what led towards more scientists exploring the theory.
Now, a new study, reported by popular website New Scientist suggest that two other researchers, —Sean Carroll from California Institute of Technology in Pasadena and Alan Guth from Massachusetts Institute of Technology— have come up with a similar model that demonstrates time moving in both directions, in ‘parallel universes.
Even though their study remains unpublished, the two researchers agree that their theory is, even more, simplified than that proposed by Barbour and his team since their study does not rely on gravity or particles confined in another system. According to reports, the study proposed by Carroll and Guth is based on the concept of entropy alone and does not include any other preconditions, meaning that it applies to particles in ‘infinite space’ rather than self-contained systems as in previous studies.
“We call it the two-headed arrow of time,” Guth tells the New Scientist. “Because the laws of physics are invariant, we see exactly the same thing in the other direction.”
The theory, however, is far from being accepted in the scientific community as reports suggest. According to New Scientist, there are initial stages in the model where the direction of entropy growth—and so the arrow of time—is not clearly defined, and so difficult to account for.
Barbour added that the work is being based on everything we know about classic physics.
Once questions of quantum physics are introduced, “all bets are still off.” He adds:
“Instead of having two streams emanating from a river, it could be more like a fountain where you have lots of pairs of springs. Or just a whole host of springs flowing out of a fountain in different directions.”
Meteorite Studies Reveal Surprises About Earth's Formation
Meteorite Studies Reveal Surprises About Earth's Formation

Scientists now have a better understanding of three concepts regarding the early Earth: what kind of raw materials coalesced to form Earth long ago, when water arrived on our planet, and why Earth and its moon have such similar compositions.
Two studies published Wednesday (Jan. 25) in the journal Nature suggest that Earth's main building blocks were rocks similar to meteorites known as enstatite chondrites, and that the planet got most of its water gradually during the formation process, rather than in one big burst toward the end.
"The results presented in these papers lead to the troubling conclusion that the meteorites in our collection are not particularly good examples of Earth's building blocks," Richard Carlson, a geochemist at the Carnegie Institution for Science in Washington, D.C., wrote in a commentary article that accompanied the two studies in Nature. (Carlson was not involved in either study.) [Photo Timeline: How the Earth Formed]
When did water come to Earth?
Scientists have known since the 1970s that Earth rocks' oxygen-isotope abundance differs from that of most meteorites, except for enstatite chondrites, Carlson wrote. (variants of the same element that have different numbers of neutrons in their atomic nuclei.)
But Earth rocks and enstatite meteorites differ in elemental composition, so most researchers have used Earth-formation models based on different meteorites called carbonaceous chondrites, which are rich in volatiles (compounds with low boiling points, such as water), he added.
By tracking different isotopic abundances in Earth rocks and meteorites, both new Nature studies concluded that carbonaceous-chondrite-like building blocks were not common late in the Earth's formation history.
Section of the enstatite chondrite meteorite Sahara 97096. Throughout its formation, Earth accreted material that was isotopically most similar to this group of enstatite meteorites. The dimensions of the section are 10 centimeters by 4 centimeters (4 inches by 1.6 inches).

Specifically, one of the studies — by University of Chicago geochemist Nicolas Dauphas — suggested that several different meteorite types were likely responsible for the first 60 percent of Earth's growth, while almost all of the remaining 40 percent came from enstatite chondrites.
The second study, performed by Mario Fischer-Gödde and Thorsten Kleine of the University of Münster in Germany, bolstered that conclusion, showing that enstatite-like rocks probably dominated Earth's late accretion history.
These findings indicate that water came to Earth throughout the planet's formation history, and not just in a flurry of carbonaceous chondrites and/or comets near the end, as some researchers have proposed, Carlson wrote.
"If the last 0.5 percent of material accreted by Earth had been composed of a particular type of volatile-rich carbonaceous chondrite, known as a CI chondrite, an amount of water equivalent in mass to Earth’s oceans would have been added to the planet," he wrote. "Fischer-Gödde and Kleine's measurements instead show that this late-accreted material consisted of relatively 'dry' enstatite chondrites."
However, this conclusion still leaves a question: Why doesn't Earth's surface composition match that of enstatite chondrites? Carlson suggested two possible explanations: Earth's deep interior is very different from the surface (which is unlikely for a variety of reasons, he wrote), or, as Dauphas suggested in his paper, the enstatite chondrites were altered on Earth's surface as the planet evolved.
Why is the moon so similar to Earth?
Dauphas' study also sheds light on how the moon formed. Most astronomers think that, long ago, one or more Mars-size bodies smashed into the proto-Earth, blasting out material that eventually coalesced to form the moon.
Models suggest that such giant impacts likely would have created a moon whose composition was different from Earth's, because proto-Earth and the impactor(s) likely would have been made of different stuff. But measurements of Earth, the moon and enstatite meteorites "have almost indistinguishable isotopic compositions," Dauphas wrote in his new study.
The apparent problem can be traced to older models that suggest a diversity of meteorites formed Earth, Dauphas added. His research, on the other hand, indicates that the proto-Earth and the moon-forming impactor(s) probably formed in the same "isotopic reservoir," which was dominated by enstatite chondrites.
"Accordingly, the giant impactor that formed the moon probably had an isotopic composition similar to that of the Earth, hence relaxing the constraints on models of lunar formation," Dauphas wrote.
Texans report mysterious ‘big boom’ with no conclusion
Texans report mysterious ‘big boom’ with no conclusion
A Texas witness at Lake Jackson reported a loud rumbling sound “like thunder” that shook the house and was followed by an unusual whining sound, according to testimony in Case 80863 from the Mutual UFO Network (MUFON) witness reporting database.
The witness recounted what happened about midnight on December 6, 2016.
“We have a mystery, locally,” the witness stated.“About 12 midnight, many people felt/heard a boom and shaking. Some people reported that it was followed by a high-pitched whine. The area that seems to have gotten the worst effects was Lake Jackson, about 12 miles from us. Some people as far as Alvin (about 35 miles away northeast), and Brazos Bend State Park, (about 30 miles north) said they had experienced it also.”
‘The Facts’ newspaper covered the story.

The witness has been hearing from more and more people who had the same experience.
“More recently, someone said that it had been reported as far away as Cypress, (80 miles north), and Porter, TX, (81 miles northeast), although those are unsubstantiated and single reports, as opposed to the hundreds of people who have been blowing up local Facebook threads. Police have checked all local chemical plants, all possible companies that place explosions to map geologic stuff – nothing. No natural gas explosions in residential areas. No major fires. Our only local paper has a thread going on their website; no news of what might have caused it. One of the Houston news channels sent a reporter, and it was treated about as credibly as a Santa sighting. (country hicks imagined feeling stuff).”
The witness believes that the incident is being treated as a mass delusion.
“Hundreds of people in the area, especially in Lake Jackson, felt their houses shake, and heard a loud rumble like thunder, although skies were clear. A friend in Detroit, TX, about 350 miles north, read my post on Facebook, and said that at about 11:30 a.m. she had heard a loud and odd rumble of thunder, and even brought it to her husband’s attention. They, also, were under clear skies.”
At least 100 witnesses at or near Lake Jackson, TX, heard a mysterious boom sound that shook homes on December 6, 2016.

Texas MUFON State Section Director Charles Stansburge investigated this case and closed it as an Unknown.
“To really get some information about what happened, I made it my duty to go to Lake Jackson and find out what I could,” Stansburge wrote in his report. “I contacted the Clute Police Department and the dispatcher said that she did not hear the boom because she was out of town. I did contact a couple of other officers and three of them that I had talked to claim they may have heard it, but they had no idea what it was and they also said that they made phone calls and to all the big companies such as BASF Corporation, Dow Chemical Company, OLIN, Phillips 66 and Chevron Phillips in the area.
“I contacted Lake Jackson Police Department and one of the officers that was there brought me into the room and we talked about what took place. I asked him if he heard the noise, and he said no, but that we did get a lot of reports coming in from people saying that their houses were even shaking because of the boom. I asked him if he knows how many that had reported it and he stated about 75 that he knew of.”
The investigator also polled people in the street – and found an additional approximately 40 new witnesses. He also described the immediate area.
“The location is one big city, Lake Jackson, with a couple other smaller towns around it. There are railroad tracks, lots of housing and businesses, police departments, sheriff’s office, schools and multiple plants such as Dow Chemical, Phillips 66 and Chevron Phillips and others. Also a few lakes and they are not far from the Gulf of Mexico.”

The investigator filed case conclusions.
“There is no real evidence of anything other than a big boom. From here I went ahead and got the phone numbers of the different plants and made a phone call and asked them what they thought it might be or if they had any problems with their planet. Every one of them said that they had no explosions and no problems with anything. They all also said that they kept the plants operational and did some investigation on their own throughout the plants and found nothing.
“I also contacted the National Weather Service and asked them about the atmosphere if that was a boom from an exploding meteorite or was it something else. They claim that they have no idea what it was other than maybe a possible meteorite in the atmosphere and it exploded, but they claim they have no information of that from anywhere. I also talked to them about any earthquakes and they claim no earthquakes anywhere around the area or even in the state or surrounding states and they are just as baffled about it as anyone.
“The others I have contacted said that other people have told them about different cities. One of those was Katie, Texas, and the police department claims they had no reports about any kind of a boom. Sugarland Police Department also claims no calls from anybody and claimed not to hear any kind of big boom. I called the Sheriff’s Office and asked about any calls of this big boom and they sent me to records and the person in records claims they had calls from citizens but she did not hear herself being inside the building. I also contacted Rosenberg Police Department and I talked to dispatch and they don’t remember having anybody call in and I asked for records and she said they were closed right now – but you can call back on Monday. I called back on Monday and records claims there were people that had called in about the boom.
“I also contacted Alvin P D, Ellington Field, Harris County Sheriff’s Office, Huston Police Department, and these were the ones that claim no calls. The city of Brazoria claim they had a few people call in. Also the Brazos Bend State Park also had people that were out in the park and Rangers as well that had heard the big boom.
“I contacted the Clute newspaper which is called The Facts and they went ahead and gave me a copy of the paper with the article in it.
“At the time of the big boom, which was on the 6th of December, I was sitting at my computer at about 12 to 12:15 and heard a big bang and couldn’t figure it out. I even went outside to check. I did not see any smoke anywhere and had no idea what it was.
“No other cases of the big boom have been reported to our database.
“The case is completed as an Unknown with at least 100 or more people witnessing hearing this big boom with some homes shaking. As far as my conclusion is, that I don’t know what it is or what was it could have been, perhaps an atmospheric explosion of a meteorite, but nobody knows what it was.”

Soon printing a human heart on demand will no longer be sci-fi
Soon printing a human heart on demand will no longer be sci-fi

Imagine being able to grow a liver in a laboratory from cells and tissue for a transplant patient. Or engineering cells to grow into a heart valve to replace one damaged from heart disease. Around the world, start-ups — like Tokyo-based Cyfuse Biomedical — are emerging to develop such breakthroughs in the field of regenerative medicine. It is a market projected to reach $101.3 billion by 2022.
Unlike conventional medicines and treatments, regenerative medicines have the ability to restore or heal the body's own cells or create new body parts from a patient's own cells and tissues, thereby eliminating tissue rejection and the excessively long wait for a donor organ.
It may sound like science fiction, but already scientists at Cyfuse have bioprinted blood vessels able to withstand 10 times the pressure of those already in the human body, according to Koji Kuchiishi, co-founder and former CEO.
Bioprinting works like this: Scientists harvest human cells from biopsies or stem cells, then allow them to multiply in a petri dish. The resulting mixture, a sort of biological ink, is fed into a 3-D printer that is programmed to arrange different cell types and materials into a three-dimensional shape. Doctors hope that when placed into the body, these 3-D printed cells will integrate with existing tissue.
While breakthroughs in central nervous system and cardiac treatments remain in the future for now, Cyfuse's Regenova bioprinter is attracting attention from the scientific community. The bioprinter is a robotic system that facilitates the fabrication of 3-D cellular structures by placing cellular spheroids in fine needle arrays according to predesigned 3-D data. Among Cyfuse's goals: to treat spinal injuries and heart failure.
This year the company transplanted human neural tissue into the brain of a small animal with positive results. Blood vessels migrated into the transplanted tissue and the graft was healing after a month.
Cyfuse has also started a clinical trial of a cartilage project, transplanting its stem cell construct into damaged articular cartilage that will gradually differentiate into cartilage and bone and regenerate the tissue.
Cyfuse is one of a growing number of tech start-ups trying to get a toehold in the global marketplace. The sector is blossoming due to innovations in stem cell therapy and tissue engineering. North America accounted for nearly 50 percent of revenue share of global market revenues for regenerative medicines in 2016. Europe is second, at US$24 billion, with Germany leading the region.
Japan and South Korea are steadily gaining ground, however. Japan's Ministry of Economy, Trade and Industry forecasts the regenerative medicine market to grow to 1 trillion yen ($9.6 billion) domestically by 2030.
With technological adoption and emphasis on research of these medicines, Asia-Pacific is currently one of the fastest-growing regions for regenerative medicine.
The medical power of Japanese art
While there are several companies around the globe leading the 3-D bioprinting space — including Organovo in San Diego, Aspect Biosystems in Vancouver, 3D Bioprinting Solutions in Russia and Rokit in South Korea — Cyfuse says its Kenzan method, a proprietary technique developed by Cyfuse co-founder and human tissue engineer, Koichi Nakayama, differentiates it from the pack.
Named after the spikes used to secure flowers in place in the Japanese art of Ikebana, Kenzan relies on the cultivation of cell aggregates into spheroids that are skewered on stainless-steel spines in the bioprinter.
Regenova is also scaffold-free, meaning the printer fabricates tissue without needing to add any extraneous matter that might pollute it. And unlike many of the other bioprinters, there is no need for collagen or hydrogels; the cells produce their own extracellular matrix.
"To unlock the potential [of bioprinting], it's going to take the marriage between the machine and the imagination of scientists."
-Dr. David Yu, vice president of business development at Cell Applications
In February 2016, San Diego-based Cell Applications became the first U.S. company to use Regenova. In the same month, Virginia-based Lifenet, an institution specializing in regenerative medicine and transplants, became the first buyer anywhere in the world to purchase the system.
"I did a market assessment and review and reached out to a number of companies, including Cyfuse," said Cell Applications' vice president of sales and marketing Daniel Schroen, Ph.D. "Some of them were pretty far upstream from commercialization."
The Californian company is using the bioprinter to create 3-D tissue for a range of clients spanning academic and corporate research.
"We've printed small, tiny beating heart tissue here. We've also printed blood vessels," explained Dr. Schroen.
Medical schools are finding uses for the bioprinter as well. Pediatric cardiac surgeon Narutoshi Hibino of Johns Hopkins is using Regenova to develop bioprinted heart patches to patch the damaged hearts of patients with heart failure who are unable to cope with medication or receive complex cardiac surgery.
At the Indiana University School of Medicine, Dr. Lester Smith, assistant research professor of radiology and imaging sciences and manager of the school's 3D Bioprinting Core,is engaged in clinical biofabricating projects aimed at repairing bone and tendon damage and nipple tissue generation, as well as liver, pancreatic and breast cancer models for metabolic activity and drug-response analysis.
"The bioprinter holds promise to more naturally reproduce tissues in the body than other current bioprinting methods," said Dr. Smith.
Now, with a staff of 23, the company has eight 3-D printer systems operating at Japanese universities and five in U.S. institutions and companies.
While Cyfuse's prospects seem bright, just how quickly futuristic ideas resembling science-fiction fantasy can be realized is unknown.
"This system has a lot of potential because it is unique in many ways," said Dr. David Yu, vice president of business development at Cell Applications. "To unlock that potential, it's going to take the marriage between the machine and the imagination of scientists.
When liquid water was first discovered on Mars, experts thought the water was too salty to sustain life. But now a new study, published on the preprint archive server biorXiv, has shown that Earth microbes can survive in extremely salty waters, which suggests that alien microbes on Mars may have survived in them.
A long-time supporter of the Roswell UFO theory appears to have concluded he was wrong.
It is a question that has been at the forefront of the UFO debate ever since, with claims surfacing that dead aliens were even found there.
Roswell has been at the heart of the UFO scene since the military announced in a press release it had found the remains of a crashed flying saucer in the nearby desert, in July 1947.
But the following day it retracted the statement, saying it was in fact a damaged US Air Force air balloon.
Witnesses later came forward to say there had been alien bodies within the "crashed craft", which along with the wreckage were then taken to the mysterious top-secret Area 51 military base in Nevada.
MUFON
A CGI image of a 'boomerang UFO' said to have been seen in Roswell.
But, now one of the leading supporters of the theory that aliens did crash land in the destroy nearly 70 years ago, appears to have had second thoughts.
Kevin Randle co-wrote with Donald Schmitt the 1991 book UFO Crash at Roswell, and in 1994, The Truth About the UFO Crash at Roswell.
But, in a new solo book revisiting the case, entitled Roswell in the 21st Century, he appears to have reached a different conclusion.
Writing on his own blog after a debate blew up on line that he had recanted the whole Roswell case in his new book, Mr Randle stopped short of a full admission of this, but did admit to a change of heart.
He said: "The question being asked about me, but never actually put to me, is if I have abandoned the alien model for the Roswell crash.
The short, flip answer is read the book.
"The more lengthy answer is well sort of.
"The book was meant to be a cold case look at the Roswell crash, starting at the beginning and shifting through the mountains of evidence that have been gathered by a number of researchers… all of whom seemed to have a biased opinion from 'yes, it was alien' to 'no, it was a Mogul balloon'.”
"To all of them (which at one time included me with some of them), I say I don’t know.
The question being asked about me, but never actually put to me, is if I have abandoned the alien model for the Roswell crash. The short, flip answer is read the book. The more lengthy answer is well sort of.
Kevin Randle
"And there you have it… I go through the whole story, document it as best I can, and in the end, I have to say that the case is built on testimony gathered decades after the fact and that everything we know about memory is that it really is no good when it comes to something like this."
Mr Randle in his new book said he had concluded that the eight people who told him they had actually seen alien bodies at the crash site "had not been telling the truth."
Sceptic Robert Sheaffer, who wrote Bad UFOs: Critical Thinking About UFO Claims, said: "So Randle has raised the number of those who lied about seeing alien bodies at Roswell from four to eight, and there never were more than eight.
"This completely undercuts the need for bizarre ET or non-ET explanations for alleged alien body sightings at Roswell.
"Stalin and Mengele sent in deformed children in a Commie Nazi saucer: Annie Jacobs.
"The US Army flew in dwarfish captured Japanese pilots in a bizarre craft: Nick Redfern. "The Air Force dropped crash test dummies in the desert: US Air Force.
"All of these highly implausible explanations are unnecessary, because there are no truthful accounts of alien bodies at Roswell to explain.
"Randle doggedly pursued the Holy Grail of alien evidence at Roswell for more than thirty years.
"When he realised it wasn't there, he was brave enough to admit it."
UK UFO expert, Nigel Watson, author of the UFO Investigations Manual, does not believe the mystery will ever be solved.
He said: "Randle doesn't exactly debunk Roswell rather he hedges his bets and is open to an alien
explanation, but at the moment we don't have sufficient evidence to say one way or the other.
"Given the time lapsed and the many contradictory witness statements and rumours surrounding this incident I don't think there will be an answer that satisfies everyone, unless of course it was an alien spaceship craft and the US releases this to the public."
But Nick Pope, a former UFO researcher in the UK Ministry of Defence, has launched a campaign to solve the case before the 70th anniversary this July, in the hope that someone in the town hung on to a piece of the wreckage and can produce it.
