Forget the Nuclear Smoke — Now Elon Musk Wants to Terraform Mars With Mirrors
Forget the Nuclear Smoke — Now Elon Musk Wants to Terraform Mars With Mirrors
One thing you can say about Elon Musk – he’s always thinking. (OK, there’s a lot of things you can say about Elon Musk, but we don’t have that kind of bandwidth.) Take, for example, his ideas about terraforming Mars, which came from his idea that people living inside of artificial environment enclosures on the planet might not do too well physically and mentally (think Biosphere 2), which came from his idea of colonizing Mars, which … you get the idea – Elon is always thinking. How could humans live on Mars without airtight habitats? By turning the planet into a junior Earth, and the best way to do that is by creating an ultra-fast evolution from barren dirt to bountiful rainforests … or at least enough food and atmosphere to live, work and survive outside. And his original idea for doing that was …
This goes back to 2015 when Musk first said his solution for raising the temperature on Mars to make it habitable for humans would be to “Drop thermonuclear weapons over the poles.” Once the smoke cleared, Musk figured enough trapped CO2 would be released from Martian soil to create an instant Earth atmosphere and kickstart an evolution. Scientists – both environmental and rocket – as well as ethicists and other humans have been objecting to this idea ever since, but busy idea-man Elon has just gotten around to coming up with a new one.
“Might make sense to have thousands of solar reflector satellites
to warm Mars vs artificial suns (tbd)”
That’s a mighty big ‘to be determined’ – starting with how does one get thousands of solar reflector satellites into Martian orbit – but it’s less radioactive (both literally and figuratively) so it has generated some consideration and reflection. Not because Elon said it but because Rigel Woida, an optical sciences and engineering student at the University of Arizona, wrote an award-winning paper in 2007 on using large aperture, lightweight orbital mirrors for terraforming targeted areas on the Martian surface. He proposed orbiting a 1.5-km array of 150 segmented, 150-meter-diameter mylar balloons that would collect sunlight and beam it to a square-kilometer area of the Martian surface.
“I adjusted the aperture so the reflector would heat a square-kilometer of Mars’ surface to roughly Tucson daytime illumination and temperatures. This would have immediate benefits for the astronauts. It would increase the light level, solar panel energy collection and bring the temperature of that part of the planet up to Earth’s. Astronauts wouldn’t have to work in freezing temperatures or spend energy thawing frozen water – water they need for manufacturing fuel to return to Earth, as well as water needed for consumption. Eventually, using techniques like these, humans might cultivate plants on Mars.”
It’s a start
That’s EXACTLY what I mean, Elon is probably thinking but certainly not saying for obvious reasons. Woida received a $9,000 NASA Institute for Advanced Concepts (NIAC) Student Fellows Prize for his idea. Musk received … well, that’s “tbd.” This idea seems more scientifically possible and certainly less radioactively controversial. But, is it ethical to terraform any other world to turn it into a junior Earth for the purpose of Earthlings colonizing it? Remember what happened on Earth so many times when settlers brought their own plants and animals to new lands? Are they the invasive species … or is it the humans who thought it was a good idea?
That answer requires more than just thought, doesn’t it? Elon?
Invisible flying object that sunds like a jet interrupts beam of high power laser pointer
Invisible flying object that sounds like a jet interrupts beam of high power laser pointer
Lately, many strange and unknown flying objects have been observed in the sky. Now, according to the latest reports and published by Linda Moulton Howe, people heard strange jet-like sounds but their were no planes, even according to two witnesses, the invisible craft interrupted the beam of high power laser pointers.
Image: Transparent ‘invisible’ craft photographed in the sky above Kaufman, Texas on July 19, 2016.
On August 14, 2019, a scientist in San Diego, California, who has heard loud jet noises in clear sky and two times flashed a powerful laser in direction of unexplained jet noise and saw the beam interrupted by something invisible.
Earlier this month, a Boeing employee witnessed the same phenomenon.
Boeing employee: “I took my high power laser pointer and shot it up in the direction of the unexplained loud jet sound. … On two separate occasions, I have seen the beam interrupted momentarily — It seems to me there is a real physical object moving through the air that is simply not visible.”
In both cases the laser beam was interrupted - Does that mean that there is a real physical object moving through the air that is simply not visible?
In the next video Linda Moulton Howe talks on the invisible flying object reported by the Boeing employee. (Report starts at the 9.50 mark in the video.)
A mysterious UFO above Amsterdam triggered a lot of speculations online about space alien craft sightings and even dark angels.
A strange aerial event was recently observed in the skies above the Dutch capital just as a tornado wreak havoc across the city centre last week.
YouTube channel Mavi777 uploaded the video online showing what seems to be a glowing UFO in the sky close to the top of the swirling column. The footage was reportedly recorded on August 10 as stated in the caption, but the integrity of it could not be immediately confirmed.
The unusual event shown in the clip led several social media users to suspect a possible appearance of a UFO with some of them claiming that these objects and the plasma orb lights are dark angels or the fallen ones that cauterise and kill animals for genetic parts and suck all the blood out as a sacrifice.
When the first dead bull turned up at the end of July, it didn’t raise an alarm at the Silvies Valley Ranch.
Cattle sometimes die suddenly on the ranch’s 140,000 acres in Harney County — struck by disease or felled by a broken leg and unable to find a way out of the rugged, forested terrain.
But by the time ranch hands discovered four more dead bulls within 24 hours, they knew they were likely dealing with deliberate, premeditated killings.
They’re still baffled by the circumstances. There were no wounds. No signs of a struggle. And the bulls’ genitals and tongues had been carefully removed.
The killing and mutilation of the 4 and 5-year-old Hereford bulls in the prime of their productive lives has since spurred a multi-agency investigation in eastern Oregon, but detectives have turned up no leads and haven’t yet even settled on a cause of death.
“How somebody put these bulls on the ground at what would be arguably a fairly close range — and to do it in a way that didn’t leave any signs, no trace evidence, no footprints, no struggle marks from the animal, no broken limbs — I have no idea,” said Colby Marshall, vice president of the Silvies Valley Ranch.
The mystery deepens because there’s no obvious reason someone would want those animal parts. They aren’t prime targets for black market sales, authorities said.
The deaths are eerily similar to a rash of livestock killings and mutilations across the West in the 1970s, when hundreds of cows and bulls turned up dead, also of seemingly unknown causes and with their genitals and tongues missing.
Back then, theories ran the gamut from a government conspiracy and UFOs to natural deaths and scavengers. Today, the circumstances at Silvies Valley Ranch point to humans as the probable culprits because of the precise cuts on the bulls.
Anything else for now is speculation, including ideas of what might have killed a bull without leaving marks. Marshall said he wonders if the killer used poison darts.
“We think that these are very sick and dangerous individuals and they need to answer for this horrible crime,” he said.
***
Silvies Valley Ranch, about 40 minutes north of the county seat of Burns, has put up a $25,000 reward for information on the bull killings that leads to an arrest and conviction, and the Oregon Cattlemen’s Association has offered its own $1,000 reward.
The investigation has pulled in Oregon State Police as well as the U.S. Forest Service because the cattle were grazing on a federal allotment in the Malheur National Forest.
The ranch is owned by veterinarian Scott Campbell, who bought the enterprise in 2006. Since then, it’s expanded into tourism with a golf course and resort on site, but still maintains around 4,500 head of beef cattle, including around 100 bulls.
The five dead bulls were found on July 30 and 31, in a wooded area about 15 miles from U.S. 395, the nearest major road. They were each about a quarter mile apart, Marshall said. There is some official disagreement on when they were killed — the Harney County Sheriff’s Office, which saw only four of the bulls, puts the deaths at three to 14 days before discovery, but Marshall believes the cattle were discovered within 24 to 48 hours of their deaths.
The delay in finding the animals is not unusual in such a remote area, where ranchers are tasked with patrolling large tracts of land, said Jerome Rosa, executive director of the Oregon Cattlemen’s Association. Harney County is Oregon’s largest county, covering more than 10,000 square miles where cattle outnumber people 14-to-1.
“These are huge, vast, steep landscapes with lots of rock and trees and brush,” Rosa said. “Ranchers may not see their cattle for long stretches of time.”
Beef is Oregon’s largest agricultural commodity, drawing in nearly $1 billion a year – and most cattle crimes typically involve theft, Rosa said.
This makes the deaths at Silvies Valley Ranch particularly bizarre, he said, because the bulls were worth a lot of money alive, particularly for breeding.
Marshall estimated their value at up to $7,000 apiece and said they would have sired at least 100 calves each over the remainder of their lives.
“Their productive life was a huge economic opportunity for the ranch, and now that’s completely lost,” he said. “We’re talking hundreds of thousands of dollars.”
Silvies Valley Ranch
The five dead bulls were found on July 30 and 31, in a wooded area about 15 miles from U.S. 395, the nearest major road. Their genitals and tongues had been cleanly removed.
Marshall has heard from several other Oregon ranchers who reported similar killings on their property over the past few decades — including cows that had been found with their udders, vulvas and tongues removed.
One of these ranchers, Terry Anderson, found a dead cow on land he was renting near Pendleton in 1980. Its udder had been cleanly removed and Anderson could see no clear evidence of what had killed the animal.
“There was no visible bullet hole or anything there,” Anderson recalled this week. “It was so unusual. It just left you with an eerie feeling.”
The hundreds of cattle deaths in the 1970s — largely concentrated in the Midwest — caused a media sensation as ranchers roiled by an economic crisis blamed a government conspiracy, according to Michael Goleman, a history professor at Somerset Community College in Kentucky who researched the phenomenon.
Because the killings were scattered across different states, investigators reached no overarching conclusion on the cause of the deaths, but Goleman said some people believed the government was conducting weapons tests on the cattle.
Facing pressure from ranchers, the FBI opened an investigation in 1979 into the deaths of 15 cattle in New Mexico, ultimately concluding that there was no evidence of intentional mutilation by humans and the animals had likely died of natural causes.
Since then, scattered reports have made headlines, including the discovery of several mutilated cows in Kansas in 2016 and five cows in 1990 that had been killed and dissected on a farm in Washington. Goleman said conspiracy theorists have pinned the blame on everything from satanic cults to aliens.
But Silvies Valley Ranch isn’t placing its bets on paranormal activity, though Harney County Sheriff’s Deputy Dan Jenkins said he’s gotten a few suggestions that Sasquatch may be responsible. He’s received around 20 calls from around the western U.S. since news about the deaths started spreading.
Jenkins, the lead investigator on the case, said the lack of physical evidence at the crime sites — no footprints, no tire or ATV tracks — means authorities are relying on witnesses to call in to the tip line and report any suspicious activity they might have seen in the area.
***
David Bohnert, a professor at Oregon State University who studies beef cattle, said two things typically kill livestock: poisoning from eating toxic plants and people.
In this case, poisoning is unlikely, given the number of bulls involved and the plants in the area, he said. Larkspur typically flowers earlier in the year, while hemlock, another deadly plant, grows only around rivers and streams — not the dry forests where the bulls were found.
Plus, the fact that all five cattle killed were bulls, Bohnert said, is statistically unlikely to occur in nature — they make up only about 4% to 6% of a herd.
That leaves human activity as the most likely cause, he said. Adding to the evidence is the surgical precision with which the genitals and tongues were removed. Scavengers would leave obvious signs of tearing with teeth, claws or beaks, he said.
Bohnert said he has heard rumors of bull testicles being considered an aphrodisiac, and both tongues and genitals can be eaten — the famous “Rocky Mountain Oysters” come to mind. But he could think of no reason why someone couldn’t just legally buy the animal parts.
Yet the human explanation comes with its own difficulties.
Taking down a 2,000-pound bull is no easy feat, and Marshall said there were no signs of a struggle — the bulls were all lying on their sides as if they had just fallen over and died.
He said he could only think that some kind of toxic dart might kill a bull from a distance. But he has no proof of it and may never find it. It’s not clear if a dart would leave a detectable imprint.
In the meantime, tissue samples taken from the carcasses are still being analyzed for toxins and no results are available yet, Marshall said. Even with the tests, the killings may remain an enigma. The bulls had been left to decompose for several days, making a toxicology screen difficult to do, he said.
Until a suspect is found, ranch employees are on high alert, particularly those who patrol vast areas alone on ATV or on horseback.
Rosa said the news had also concerned other ranchers — but that greater awareness could also lead to faster answers in the tight-knit ranching community.
“The neighbors and the folks that are in those areas know each other,” Rosa said. “And when there’s someone strange or different that’s out and about, they take notice of that, and they let each other know.”
Crop circles have been appearing around the world for centuries.

IT all started with a UFO sighting.
Dr Horace Drew, 61, was just 10 years old when he allegedly saw an unidentified, silver, windowless craft hovering in the sky near his suburban home, in Jacksonville, Florida. The encounter lasted only moments but led to a lifelong fascination with the extraterrestrial.
“I saw a UFO, so I knew they were real from an early age,” Dr Drew told news.com.au.
The scientist, who holds a PhD in Chemistry from Caltech, the California Institute of Technology, and worked for CSIRO as a molecular biologist, has been researching crop circles and aliens for 20 years. Dr Drew relocated to Australia in the 1980s but most of his work has taken him overseas, predominantly to Europe.
“They’re quite rare in Australia,” he said.
He, along with many conspiracy theorists, believe crop circles are the work of aliens or human time travellers. Sceptics say most are probably man-made.
A crop circle is typically defined by standing wheat stems that have been flattened in the shape of a circle or more complex pattern. They tend to appear mainly in developed Western or secularised countries — including Japan.
The cause of many of the circles is unknown despite various natural and unorthodox explanations having been put forward. Some crop circles have been proven to be hoaxes.
But according to Dr Drew, a number are legitimate and contain puzzles that can be decoded and linked to time travel and alien life.
He told news.com.au he had visited about “two dozen crop circles” around the globe in his career. Typically, they were between 50-500m in length, he said.
“This has led to at least one major breakthrough the discovery of a more advanced binary code than our computers currently use.”
Dr Drew claimed that aliens or human time travellers have been leaving the crop circles on Earth as messages to “us or themselves”.
Sightseers visit an incorporated oversized crop circle in a cornfield, not far from the small community of Mammendorf near Munich, southern Germany, on August 3, 2016. The crop circle had a diameter of 180 metres.

WHY ARE THERE CROP CIRCLES?
Dr Drew said he was one of a handful of scientists around the world who had worked to successfully decode some of the messages in crop circles.
According to him, some crop circles provide general descriptions of the future.
“Other crop (circles) show schematic images of the future for astronomical or human events,” he said.
He said some of the decoded messages read: ‘Much pain but still time. Believe. There is good out there’; ‘Beware the bearers of false gifts and their broken promises’; ‘We oppose deception. Conduit closing’.
Dr Drew has developed at least two theories as to the purpose of the circles by reading their “advanced (version of) binary codes”.
“One theory is that they are trying to introduce themselves to us peacefully, like we do using bubbles with dolphins,” he said.
“When (humans) want to talk with dolphins we put little bubble circles under the ocean with a generator. We watch the dolphins come up and play and investigate, and we study them.
“This is called the ‘dolphin communication project’.”
He said the dynamic between the way humans interact with dolphins and whales was likely comparable to how extraterrestrials communicate with us.
“Barack or Trump have never said to a dolphin: ‘take me to your leader I want to sign a treaty with you’,” he said.
“And (the extraterrestrials are) not interested in making a treaty with us.
“They are ahead of us like we are ahead of the dolphins and the whales.”
His second theory was that the messages “are not even for us”.
Dr Drew said human time travellers from the distant future could be creating the circles as directional markers, to help them navigate “in their distant past, which is our present”.
“There are definitely humans living there in about 5000 years with time travel capability,” he said.
“They’re coming back and flying all over Earth.
“They seem to just say ‘this is a certain day’ and mark it.
“So the trouble is we don’t know space time physics enough to understand what’s happening. It’s beyond our knowledge.
“Maybe they don’t want us to know about it. It might be just for them.”
It’s a theory shared by many in his field of work.
A crop circle once appeared in field of wheat at Clay Hill, Warminster, Wiltshire. The site, made famous by UFO sightings in the 60s and 70s, had crop circle experts baffled over the 200 foot design.

HOW ARE THEY MADE?
Dr Drew said the circles appeared to be created by an “unknown energy that heats the crops up”.
“It’s like microwave energy but is something beyond earth’s science,” he said.
“It can pattern the wheat.
“No one sees or hears anything and that's why its so hard to prove. If there’s a craft, it’s silent, noiseless.”
But there’s nothing to fear, according to him.
“Don’t be afraid,” he said.
REAL OR A HOAX?
Telling the difference between a real crop circle and a hoax is like differentiating between an original painting and a fake, according to Dr Drew.
“There are some things to look for,” he said.
Crops that are bent “halfway up” their stems, rather than on the ground ,is one telltale sign “cereologists”, or someone that advocates paranormal explanations of crop circles, look for to determine that it’s not a hoax.
“You can’t absolutely prove a crop circle wasn’t a hoax but you can give a high probability and judgment,” he said.
“If there’s a hoax the word of it gets around very fast, people are aware, people are not that easily fooled.”
Scientist Dr Horace Drew said he took this photos in a “newly found crop” circle at Etchilhampton near Decizes, England in July, 2012. “About 25 per cent of fallen wheat stems inside the picture were bent by unknown energies,” he told a conference on Wednesday.

In 1991, English pranksters Doug Bower and Dave Chorley took credit for most of the crop circles across southern England made since 1978. They were inspired by the Tully “saucer nest” case in Australia, where a farmer found a flattened circle of swamp reeds after observing a UFO.
Using basic tools including a plank of wood, rope, and a baseball cap fitted with a loop of wire to help them walk in a straight line, they said they made complex crop circles in England — which others then copied all over the world into the 1980s.
They made a circle for journalists, which was later declared authentic by a cereologist. They then revealed their hoax to the world, spurring on even more copycats.
Scientist Dr Horace Drew has been researching crop circles and aliens for 20 years.

Dr Drew said there was a lot of scientific evidence to show that some crop circles were made by human time travellers or extraterrestrial beings. “Laboratory results on plant or soil samples taken from a crop circle in Brazil in October of 2016 show that it was formed by unknown sterilising images,” he said.
The earliest mention of a crop circle dates back to the 1500s. A woodcut from the time showed a “mowing devil” making the pattern.

GOVERNMENT SECRETS?
Earlier this month, US TV host Jimmy Kimmel asked former US President George Bush if he went through “secret files, the UFO documents” when he was in office.
But instead of laughing off the question, the former commander in chief replied: “Maybe.”
Mr Kimmel then asked him if there were “any great secrets you know that you can’t share with people?”
“Yeah, there are,” Mr Bush said. “But I’m not telling you.”
Many conspiracy theorists and some scientists, including Dr Drew, argued that Mr Bush’s comments indicated the US government knows much more about extraterrestrial life than it has publicly revealed.
“The politicians are scared they'll lose votes if they talk about it,” Dr Drew said.
He said international media had also played a part in causing the public to doubt the legitimacy of crop circles and aliens.
But according to him, its important for humans to keep seeking answers.
“The ET visitors have technologies which would benefit us greatly, for example, how to make safe, clean energy without burning oil, coal or gas,” Dr Drew said.
“Ultra-fast propulsion systems, based on gravity and inertia, could carry us safely to distant planets or stars.
“We may also need to upgrade our planetary defences soon, to protect against ET’s who may not be friendly.”
There’s still a lot more to be understood but Dr Drew’s hope is that he one day gets a closer look at what was inside the UFO he believes he saw as a child.
“I’d like to meet (the extraterrestrials or human time travellers) in person,” he said.
“But I don’t think they're going to do that.
“Whichever scientific team is doing this I don’t think we’re supposed to have full knowledge of it because it will interrupt their program, whatever they're doing.”
NASA announced in 2012 that it was working to build a "warp drive" that could enable "faster-than-light" travel. Two years later and the space agency hasn't built a spaceship capable of such speeds yet — but thanks to artist Mark Rademaker, we now know what one could look like. The result is the IXS Enterprise, a ship that shares similarities with both its science fiction Star Trek namesake, and NASA's real-world space shuttle.
Rademaker worked together with NASA's Dr. Harold White to produce visual concepts for the craft. White and his team at NASA are hoping to make "faster-than-light" travel possible with Alcubierre drives. The drives, named for physicist Miguel Alcubierre, theoretically work by distorting space-time. By expanding the space behind a ship and contracting the space in front of it, the IXS Enterprise could drastically speed up our space travel potential, making the 4.3 light-year journey to Alpha Centauri in around two weeks.
Rademaker says he was influenced in the design for his Enterprise by Matt Jefferies' sci-fi artworks from the 1960s. But where famed aviation artist Jeffries, who helped create the spaceships of the Star Trek universe, imagined spindly craft with thin rings, the IXS Enterprise sits inside two circles chubby enough to power its Alcubierre drive. The spacecraft is fatter than most of Jefferies' sci-fi ships, too, capable of bearing four cylindrical pods on its flanks, and sporting a wide, flat, duck's bill of a command module. Speaking at the SpaceVision conference last year, Dr. White justified the design, saying that "if you're going to go to all the trouble of making it that big, you might as well fit all you can in there."
Until NASA announces a breakthrough in its research of Alcubierre drives and "faster-than-light" travel technology, Rademaker's concepts will remain only concepts. But his visualization of the IXS Enterprise still gives us a glimpse of the kinds of vehicles we'll hopefully one day be able to use to travel to strange new worlds, to seek out new life, and new civilizations.
Scientists discovered the first planet outside of our solar system in 1992, and today more than 4,000 exoplanets have been confirmed. In a new study, researchers have found that some of these exoplanets may have conditions that are even more well-suited to host life than our own planet.
“This is a surprising conclusion,” said Dr. Stephanie Olson, who led the investigation, “It shows us that conditions on some exoplanets with favorable ocean circulation patterns could be better suited to support life that is more abundant or more active than life on Earth.”
Because it is impossible to reach such distant planets with space probes, scientists are working with remote sensing tools like telescopes to explore the conditions on various exoplanets, and sophisticated models must be used to interpret these remote observations. Dr. Olson’s team used ROCKE-3D software, which was developed by NASA to simulate the climates and ocean habitats of different types of exoplanets.
“NASA’s search for life in the Universe is focused on so-called habitable zone planets, which are worlds that have the potential for liquid water oceans. But not all oceans are equally hospitable – and some oceans will be better places to live than others due to their global circulation patterns,” said Dr. Olson.
“Our work has been aimed at identifying the exoplanet oceans which have the greatest capacity to host globally abundant and active life. Life in Earth’s oceans depends on upwelling (upward flow) which returns nutrients from the dark depths of the ocean to the sunlit portions of the ocean where photosynthetic life lives. More upwelling means more nutrient resupply, which means more biological activity. These are the conditions we need to look for on exoplanets.”
Artist’s concept shows what the TRAPPIST-1 planetary system may look like.

After modeling a variety of exoplanets with potential, the experts were able to define the types of exoplanets which stand the best chance of sustaining life.
“We have used an ocean circulation model to identify which planets will have the most efficient upwelling and thus offer particularly hospitable oceans,” said Dr. Olson. “We found that higher atmospheric density, slower rotation rates, and the presence of continents all yield higher upwelling rates. A further implication is that Earth might not be optimally habitable – and life elsewhere may enjoy a planet that is even more hospitable than our own.”
“There will always be limitations to our technology, so life is almost certainly more common than ‘detectable’ life. This means that in our search for life in the Universe, we should target the subset of habitable planets that will be most favorable to large, globally active biospheres because those are the planets where life will be easiest to detect – and where non-detections will be most meaningful.”
The research was presented by Dr. Olson at the 2019 meeting of the Goldschmidt Geochemistry Congress in Barcelona.

‘Spaceshuttle-UFO’ vastgelegd in Washington. Fotograaf doet onverwachte ontdekking
Een fotograaf uit de Amerikaanse staat Washington heeft op een foto die hij had gemaakt van Whitehorse Mountain een onbekend vliegend object vastgelegd.
De UFO is op 22 juli 2018 op klaarlichte dag waargenomen.
De getuige laat weten dat hij het object in eerste instantie niet had gezien op de foto.
Geen vliegtuigen of helikopters
Foto: MUFON
Pas na het croppen van de afbeelding en het toepassen van kleurcorrecties werd het object zichtbaar.
“Op het moment dat ik de foto maakte stond ik naar de zon gericht en moest ik de bovenkant van de camera afdekken om een lensflare te voorkomen,” zei de getuige.
“Er waren op dat moment voor zover ik weet geen vliegtuigen of helikopters in het gebied, maar het was erg warm, er stond een harde wind en er was veel verkeer, dus ik heb snel een foto gemaakt en ben weer verder gegaan,” klonk het.
Zeer interessant
Ik woon niet in het gebied, dus ik weet niet hoe vaak er lijnvliegtuigen zijn te vinden, aldus de getuige.
“Hoe dan ook was het zeer interessant om dit aan te treffen op de foto,” besloot hij.
Spaceshuttle
Een onderzoeker van het MUFON (Mutual UFO Network) in Washington heeft bepaald dat het hier gaat om een Unknown Aerial Vehicle. Onbekend dus.
Volgens sommigen lijkt de UFO erg op een spaceshuttle.
It’s official, NASA is going alien hunting. The space agency announcedTuesday that the next phase of the Europa Clipper mission is confirmed, meaning that within the next four to six year NASA will be sending a spacecraft to Jupiter’s moon Europa to determine if it can support life and maybe, just maybe, find a handful of aliens.
Europa is seen as one of the best, if not the best, candidates for extraterrestrial life within our solar system. Europa is slightly smaller than Earth’s moon and has a crust composed mostly of water ice. Europa also has an oxygen atmosphere, although it is extremely thin and would be indistinguishable from the vacuum of space for the purposes of not suffocating. But it’s not the ice surface or the thin oxygen atmosphere that excites scientists about the moon.
Because Europa is a very young moon, relatively speaking, and has the smoothest surface of any body in the solar system, scientists hypothesize that the thin ice crust of the moon actually hides a massive subsurface ocean. Estimated to be approximately 61 miles thick, this moon-wide ocean would be kept liquid by tidal flexing as the orbits close to Jupiter. Scientists believe that the ocean pulls down chemicals from the moon’s surface. A big, warm-enough-to-be-liquid, salt water ocean that sucks in chemical compounds. Sounds like a prime alien-fishing hole.

The Europa Clipper mission would be the first spacecraft to study the surface of Europa. Previous missions have flown by and taken some stunning pictures, but none have been able to study what’s happening on or below the surface. the confirmation of the mission allows the next steps to be taken in the construction and testing of the spacecraft and science payload. In a press release, Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington, said:
“We are all excited about the decision that moves the Europa Clipper mission one key step closer to unlocking the mysteries of this ocean world. We are building upon the scientific insights received from the flagship Galileo and Cassini spacecraft and working to advance our understanding of our cosmic origin, and even life elsewhere.”

So when will we see it launch? 20 years? 40? Actually, it should be much sooner than that. NASA says that in the interest of cost-efficiency they are planning to have the equipment built and ready for launch as early as 2023. However they say that failing a 2023 launch date, the latest it would launch is 2025.
So it will launch pretty soon, relatively speaking. After it does launch however, Europa Clipper will take roughly six years to reach its target. This is due to space being big. So we have until 2031, on the outside range, to see if there are any alien-fish or space-dolphins out there. That is, of course, unless things go weird at Area 51 next month.
NASA found alien planet that has tri-star sky like in ‘Star Wars’
NASA found alien planet that has tri-star sky like in ‘Star Wars’
NASA has discovered an exoplanet with three “suns” in its sky. Star Wars, anyone?
Astronomers think they've spotted an alien planet with three suns on its horizon, but that still isn't the most interesting thing about the strange new world's sky.
Scientists found the world, which they've dubbed LTT 1445Ab, in data gathered by NASA's Transiting Exoplanet Survey Satellite (TESS).
LTT 1445Ab orbits just one of the three stars, all of which are red dwarfs in the latter half of their lives, and the system is about 22.5 light-years away from Earth.
"If you're standing on the surface of that planet, there are three suns in the sky, but two of them are pretty far away and small-looking," co-author Jennifer Winters, an astronomer at the Harvard-Smithsonian Center for Astrophysics, told New Scientist. "They're like two red, ominous eyes in the sky” reports Space.com.

WETENSCHAP & PLANEETDe Amerikaanse ruimtevaartorganisatie Nasa heeft een steen op Mars naar de rockband Rolling Stones genoemd.
De “Rolling Stones Rock” is iets groter dan een golfbal, zo liet de Nasa donderdag weten op een persconferentie in het Californische Pasadena.
De steen was in beweging gezet door de turbulentie die door de motor van het landingstuig Insight werd veroorzaakt bij de landing in november 2018. Daardoor was de steen enkele meters verderop gerold. De sporen daarvan zijn op oranjerode foto’s van het Marsoppervlak te zien. Het is de eerste keer dat een Nasa-ruimtevaarttuig op een vreemde planeet een steen op die manier in beweging heeft gezet, aldus de Nasa.
“Dit is een mijlpaal in onze lange en bewogen geschiedenis”, lieten de Stones donderdagavond weten op hun concert in Pasadena.

Archeologen ontdekken drie ‘buitenaardse’ schedels in Kroatië - HLN.be
Archeologen ontdekken drie ‘buitenaardse’ schedels in Kroatië - HLN.be
PLOS OneDe drie schedels waren afkomstig van 'gewone' jongens die 12 tot 16 jaar oud waren toen ze stierven. De rare vorm van hun schedel is het resultaat van opzettelijke schedelvervorming.
WETENSCHAPIn Kroatië zijn drie menselijke schedels opgediept, al twijfelden de archeologen een fractie van een seconde of het niet over de restanten van buitenaardse wezens ging. Tenslotte hadden de schedels een puntige, onaardse vorm. In werkelijkheid ging het om kunstmatig vervormde schedels.
De schedels werden in 2013 reeds teruggevonden op een archeologische site in Osijek. De jaren daarop werden de merkwaardige schedels geanalyseerd en die analyse werd nu gepubliceerd in het tijdschrift PLOS One.
Doodsoorzaak Uit de resultaten van de archeologen blijkt dat de schedels wel degelijk afkomstig waren van drie ‘gewone’ jongens die zo’n 1.550 jaar geleden stierven. Op dat moment waren de tieners vermoedelijk 12 tot 16 jaar oud. Daarbij waren ze duidelijk ondervoed, maar onduidelijk is nog of ze daaraan ook gestorven zijn.
Hun geschatte sterfdatum (415 tot 560 na Christus) komt immers overeen met de val van het Romeinse Rijk. Daarop kwamen nieuwe bevolkingsgroepen en culturen aan in Europa, alsook strubbelingen en nieuwe ziektes.
En wat dan met die vreemd gevormde schedels? Het klinkt misschien gek, maar het fenomeen waarbij de schedel opzettelijk vervormd werd, kwam in verschillende werelddelen voor. Mensen met zo’n vreemd hoofd vervulden doorgaans een hogere positie in de samenleving, wilden hun intelligentie in de kijker zetten, en/of dichter bij de geesten staan.
Het vervormen van de schedel gebeurde voornamelijk bij kinderen, omdat een kinderhoofd nog tamelijk ‘plooibaar’ is. Bij de kinderen werd het hoofd dan tussen twee houten planken gewikkeld waardoor een geforceerde en onnatuurlijke groei werd opgedrongen. Het resultaat? Langwerpige en puntige schedels die een onaardse indruk nalaten.
Natuurlijk liepen de praktijken waarbij het hoofd werd vervormd, niet altijd succesvol af. Zo zijn er reeds talrijke restanten ontdekt van kinderen die hoogstwaarschijnlijk stierven na het uitvoeren van een zogenaamde schedelbinding.

Earth is an Exoplanet to Aliens. This is What They’d See
Earth is an Exoplanet to Aliens. This is What They’d See
The study of exoplanets has matured considerably in the last ten years. During this time, the majority of the over 4000 exoplanets that are currently known to us were discovered. It was also during this time that the process has started to shift from the process of discovery to characterization. What’s more, next-generation instruments will allow for studies that will reveal a great deal about the surfaces and atmospheres of exoplanets.
This naturally raises the question: what would a sufficiently-advanced species see if they were studying our planet? Using multi-wavelength data of Earth, a team of Caltech scientists was able to construct a map of what Earth would look like to distant alien observers. Aside from addressing the itch of curiosity, this study could also help astronomers reconstruct the surface features of “Earth-like” exoplanets in the future.
The study that describes the team’s findings, titled “Earth as an Exoplanet: A Two-dimensional Alien Map“, recently appeared in the journal Science Mag and is scheduled for publication in The Astrophysical Journal Letters. The study was led by Siteng Fan and included multiple researchers from the California Institute of Technology’s Division of Geological and Planetary Sciences (GPS) and the NASA Jet Propulsion Laboratory.

When looking for potentially habitable planets beyond our Solar System, scientists are forced to take the indirect approach. Given that most exoplanets cannot be observed directly to learn of their atmospheric composition or surface features (aka. Direct Imaging), scientists must be satisfied with indications that show how “Earth-like” a planet is.
As Fan told Universe Today via email, this reflects the limitations that astronomers and exoplanet studies are currently forced to contend with:
“Firstly, current exoplanet studies have not figured out what the least requirements are for habitability. There are some proposed criterions, but we are not sure if they are either sufficient or necessary. Secondly, even with these criterions, current observation techniques are not good enough to confirm the habitability, especially on Earth-like exoplanets due to the difficulty of detecting and constraining them.”
Given that Earth is the only planet we know of that is capable of supporting life, the team theorized that remote observations of Earth could act as a proxy for a habitable exoplanet as observed by a distant civilization. “Earth is the only planet we know that contains life,” said Fan. “Studying what the Earth looks like to distant observers would give us the direction of how to find potential habitable exoplanets.”

One of the most important elements of Earth’s climate (and which is critical to all life on its surface) is the water cycle, which has three distinct phases. These include the presence of water vapor in the atmosphere, clouds of condensed water and ice particles, and the presence of bodies of water on the surface.
Therefore, the presence of these could be considered potential indications of habitability and even indications of life (aka. biosignatures) that could be observed from a distance. Ergo, being able to identify surface features and clouds on exoplanets would be essential in order to place constraints on their habitability.
To determine what Earth would look like to distant observers, the team compiled 9740 images of Earth that were taken by NASA’s Deep Space Climate Observatory (DSCOVR) satellite. The images were taken every 68 to 110 minutes over a two year period (2016 and 2017) and managed to capture light reflected from Earth’s atmosphere at multiple wavelengths.
Fan and his colleagues then combined the images to form a 10-point reflection spectrum plotted over time, which were then integrated over the Earth’s disk. This effectively reproduced what Earth might look like to an observer many light-years away if they were to observe Earth over a two year period.

“We found that the second principal component of Earth’s light curve is strongly correlated to the land fraction of the illuminated hemisphere (r^2=0.91),” Fan said. “Combining with the viewing geometry, reconstructing the map becomes a linear regression problem.”
After analyzing the resulting curves and comparing them with the original images, the research team discovered which parameters of the curves corresponded to land and cloud cover. They then picked out the parameters that most closely related to land area and adjusted it to the 24-hour rotation of the Earth, which gave them a contoured map (shown above) that represented what Earth’s light curve would look like from light years away.
The black lines represent the surface feature parameter and correspond roughly to the coastlines of the major continents. These are further colored in green to provide a rough representation of Africa (center), Asia (top right), North and South America (left), and Antarctica (bottom). What lies in between represents the Earth’s oceans, with the shallower sections denoted in red and the deeper ones in blue.
These kinds of representations, when applied to the light curves of distant exoplanets, could allow astronomers to assess whether an exoplanet has the oceans, clouds, and icecaps – all necessary elements of an “Earth-like” (aka. habitable) exoplanet. As Fan concluded:
“The analysis of light curves in this work have implications for determining geological features and climate systems on exoplanet. We found that the variation of light curve of Earth is dominated by clouds and land/ocean, which are both crucial to the life on Earth. Therefore, Earth-like exoplanets which harbor this kind of features would be more likely to host life.”
The horror flick “Alien” hit the screen 40 years ago, in the summer of 1979. The film is one of Hollywood’s best-known sci-fi blockbusters.
In the decades since “Alien” came out, depictions of aliens in movies have changed dramatically.
Instead of showing extraterrestrial life as humanoid, directors have instead depicted aliens as bacteria, as in the movie “Life,” or as amorphous lifeforms, as in the movie “Arrival.”
According to one scientist, these depictions are more scientifically realistic and align more with what researchers think aliens might look like.
The 1979 blockbuster “Alien” opens with a tension-filled scene: A spider-like creature attacks an astronaut named Thomas Kane on an unknown planet.
The crew of Kane’s ship brings him back on board with the mysterious critter still attached to his spacesuit. Under the fluorescent lights, the creature seems to die, detaching from Kane’s face. When the astronaut eventually wakes up, he seems unharmed by the encounter.
But a miniature alien later bursts out of his chest in a shower of blood as his shocked crewmates scream.
The xenomorph, as it’s called, grows to be larger than any human, with glossy black skin, razor-sharp teeth, claws, and a tail.

In the four decades since “Alien” came out – the film’s 40th anniversary was in May – that creature’s image has influenced moviegoers’ mental pictures of alien life.
But as NASA has embraced the objective of searching for extraterrestrial life in our galaxy, the scientific understanding of what extraterrestrials might look like has converged around a type of lifeform far different from the director Ridley Scott’s brainchild.
Today, astrobiologists suspect that extraterrestrial lifeforms are likely to be microscopic in nature, akin to the bacteria scientists find in extreme environments on Earth.
Hollywood filmmakers have started to embrace this idea and depict aliens as less humanoid, according to the physicist and author Sidney Perkowitz. In other words, the days of little green men and giant scaly monsters in alien movies are over.
“In the old science-fiction flicks of the 1950s and ’60s, if you did an alien, monster, or robot, it was a guy dressed up and stomping around a sound stage,” Perkowitz, who cofounded the National Academy of Sciences’ Science and Entertainment Exchange group, which connects directors with science advisers, told Business Insider. “In the last few decades, CGI has changed that, allowing for the potential of really life-like, imaginative creatures.”
No more little green men
The chance that alien life looks humanoid is infinitesimal.
“We don’t have any reason to believe that they would look anything like us,” Andrew Siemion, the director of the Berkeley SETI (Search for Extraterrestrial Intelligence) Research Center,told Vox. “The form of a human being is the result of several billion years of evolution.”
Perkowitz said that Scott and other directors’ decisions to make extraterrestrials appear human-like could simply boil down to cost.
“Humanoid aliens are cheap to portray,” he said.
He added that the problem with “Alien” wasn’t just that the movie portrayed the alien as humanoid – it was that the extraterrestrial was depicted as unintelligent and beast-like. The xenomorph doesn’t try to communicate with the astronaut crew; instead, it eats the crew members one by one until Sigourney Weaver’s character blasts it into space.
“It’s hard to imagine a different lifeform would have such a negative reaction to another lifeform – nothing lives for pure evil,” Perkowitz said, adding: “If we always decide that ‘the other’ is hostile or contemptible, how does that encourage our efforts to relate to them?”
But the examples of nonhostile aliens in Hollywood are few and far between (Steven Spielberg’s E.T. notwithstanding). That’s because, according to Perkowitz, society uses film to explore what it’s afraid of.
Sci-fi films are reflections of what society is worried about
Hollywood blockbusters’ references to science don’t arise in a vacuum – they mirror trends in scientific discovery and their effects on culture. In the 1950s and 1960s, for example, movies like “Dr. Strangelove” featured nuclear scientists because people had memories of the atomic bomb and a fear of nuclear war, Perkowitz said.
“Even if the sci-fi film doesn’t know it’s doing it, a closer watch shows that the movies reflect society’s current anxieties,” he said.
Alien movies are no different. These days, Perkowitz said, humanity isn’t afraid of carnivorous xenomorphs. Instead, he continued, we worry about “something viral – a biological entity that spreads quickly and causes harm.”
At a time when mosquitoes that carry viruses like Zika and dengue fever are spreading farther thanks to warmer temperatures, “nuclear radiation isn’t the concern anymore,” Perkowitz said. So some alien movies now depict a contagion that comes from outer space.
In the 2017 movie “Life,” for example, Jake Gyllenhaal’s character and his crewmates aboard the International Space Station discover a life form that supposedly caused extinction on Mars and threatens life on Earth.

Film studios primarily choose to present aliens as malevolent microbes in this way to get people to the box office, Perkowitz said, adding that “on the whole, Hollywood isn’t concerned with the social responsibility of getting the science right.”
But in this case, he added, the depiction could help establish more appropriate expectations for any discovery of life that NASA might make. The agency is preparing to look for extraterrestrial life on Jupiter’s moon Europa with its planned Clipper mission in 2025. Scientists think any life there “may look like microbes, or maybe something more complex,” a NASA report said.
The best portrayal of aliens in film?
Perkowitz pointed to the creatures called heptapods in the 2016 movie “Arrival” as an exemplary depiction of non-humanoid aliens that attempt intelligent contact. That’s because they don’t remotely resemble humans, are not hostile, and try to communicate rather than attack.
In the movie, Amy Adams plays a linguistics professor who works to communicate with the heptapods, which sport long muscular torsos and seven legs. Eventually, she discovers that the aliens speak using logograms – inkblot-like symbols that can stand for a word, an entire sentence, or even a feeling.
The humans and the aliens, through extensive trial and error, establish a mutual language without destroying each other.

“That movie is a great example of, perhaps, how would we really go about meeting aliens if we do ever meet intelligent life out there,” Perkowitz said
Stargazers in northern Norway enjoyed an unexpected light show when a new NASAtest showered the skies with brushstrokes of blue and orange-colored gases.
The lights, which looked like an 'alien attack' attack to some, were actually a part of an ongoing NASA experiment dubbed The Auroral Zone Upwelling Rocket Experiment (AZURE).
As a part of the mission, NASA says it has launched the AZURE test rocket -- the first of eight such planed launches -- that aim to study the patterns of solar winds.
The eye-catching lights were created by releasing two harmless gases into the atmosphere — trimethylaluminum as well as a mixture of barium and strontium — so researchers can study the paths of particles in the Earth's ionosphere, NASA says.
Scroll down for video
Captures of the show were grabbed via a webcam run by Lights Over Lapland, which helps sightseers get a glimpse of Aurora's through guided tours.
According to scientists, the experiment will also help unlock the forces behind one of nature's most capturing phenomenon, the Aurora Borealis.
Auroras — the shows of green, blue, and purple light observed in the skies of regions close to the Earth's poles — are created by solar winds interacting with the planet's magnetic field.
When the particles of the two atmospheric regions collide and their respective particles are charged, the trajectories are changed, which forces electrons and protons down into the atmosphere at which point humans are able to observe them as streaks of colorful light.
Gases released by NASA in their vapor test were subject to a similar process.
While scientists have inferred the cause of Auroras, they have yet to actually observe the pattern and behavior of solar winds and the ionosphere that drive them beyond computer-generated models.
No need to run for cover yet. Alien-like lights in skies over Norway were the result of a test by NASA to study solar winds and Earth's upper atmosphere.
Projects like the one witness by stargazers this month will help scientists gain exact measurements of both horizontal and vertical pathways of particles in the ionosphere over a range of altitudes and help increase understanding of the Auroras they create.
Solar winds have not yet been concretely tracked by scientists who rely mostly on computer-generated models.
In addition to creating beautiful displays of light, the interaction between solar winds and the Earth's magnetic field are also crucial to creating the conditions for much of our planet's life.
Solar winds, waves of particles released from the sun, are rife with radiation, which if beamed to the Earth's surface, would severely damage all of our planet's inhabitants.
Instead, however, the sun's particles are deflected away from the planet by the Earth's magnetic field, known as the magnetosphere.
NASA says its experiments will also help to glean a fuller picture of what happens when particles from the solar winds are forced into our atmosphere and exactly where they go.
HOW IS THE SOLAR WIND FORMED?
The sun and its atmosphere are made of plasma – a mix of positively and negatively charged particles which have separated at extremely high temperatures, that both carries and travels along magnetic field lines.
Material from the corona streams out into space, filling the solar system with the solar wind.
But scientists found that as the plasma travels further away from the sun, things change.
Views of the solar wind from NASA's STEREO spacecraft (left) and after computer processing (right). Scientists used an algorithm to dim the appearance of bright stars and dust in images of the faint solar wind
The sun begins to lose magnetic control, forming the boundary that defines the outer corona – the very edge of the sun.
The breakup of the rays is similar to the way water shoots out from a squirt gun.
First, the water is a smooth and unified stream, but it eventually breaks up into droplets, then smaller drops and eventually a fine, misty spray.
A recent Nasa study captured the plasma at the same stage where a stream of water gradually disintegrates into droplets.
If charged particles from solar winds hit Earth's magnectic field, this can cause problems for satellite and communication equipment.
WETENSCHAPRusland heeft bij een test met een gemoderniseerde Sojoez-draagraket en een onbemande Sojoez-capsule de humanoïde robot Fiodor naar het Internationaal Ruimtestation ISS gelanceerd. Het ding zal daar meerdere testen uitvoeren.
Van op de basis Bajkonoer in Kazachstan vertrok om 05.38 uur Belgische tijd een Sojoez-2.1a draagraket. Die slingerde de onbemande capsule Sojoez-MS-14 naar het ISS.
Deze gemoderniseerde Sojoez-draagraket moet voor bemande vluchten de sinds 2002 ingezette Sojoez-FG vervangen die ook Frank De Winne in de ruimte heeft gebracht. Het model 2.1a heeft ook al een Russische vrachtruimteschip van het type Progress gelanceerd, na sinds 2004 voor satellietlanceringen te zijn ingezet.
Eén lancering met een Progress mislukte, vandaar de test met een Sojoez-capsule die voor het eerst niet bemand is.
AFP
De capsule moet zaterdag om 07.30 uur Belgische tijd koppelen aan de Russische Pojsk-module van het ISS en vertrekt op 6 september om 20.13 uur Belgische tijd.
De capsule vervoerde alleen vracht, waaronder een humanoïde robot, die 1,80 meter groot is en bijna 160 kilogram weegt. Fiodor, alias Skybot F850, is een Russische voornaam, maar luidt in het Engels Fedor. Dat staat voor “Final Experimental Demonstration Object Research”.

Fiodor heeft een eigen Instagram- en Twitterprofiel, waarop volgers een blik krijgen in het dagelijkse leven van de robot. Zo is te zien hoe Fiodor leert om een fles water te openen.
Aan boord van de ISS zal de robot verschillende taken uitvoeren onder toezicht van de Russische kosmonaut Aleksandr Skvortsov. Hij kwam een maand geleden in de spacemeccano aan. Hij zal de vaardigheden van Fiodor testen onder micro-zwaartekracht. Een van de belangrijkste vaardigheden van de robot is dat hij menselijke bewegingen kan imiteren, waardoor hij astronauten kan helpen of taken van hen kan overnemen.
“Hij moet vijf of zes taken uitvoeren die een geheim blijven”, zei Jevgeni Doedorov, de verantwoordelijke van het bedrijf dat Fiodor ontwikkelde.
WETENSCHAP Het Roopkundmeer in de Indiase Himalaya is een mysterieuze plek. Het ondiepe bevroren gletsjermeer te midden van de besneeuwde bergtoppen ligt vol met honderden menselijke skeletten. Daaraan dankt het meer dan ook zijn lugubere bijnaam: Skeleton Lake. Niemand weet echter hoe al die menselijke botten daar beland zijn. Nieuw DNA-onderzoek maakt het mysterie nu nog groter.
Onderzoekers schatten dat er zo’n 500 menselijke skeletten op de bodem van het meer liggen. Het Roopkundmeer ligt langs de route van de Nanda Devi Raj Jat, een beroemd festival en pelgrimstocht. De botten liggen verspreid over de bodem, geen enkel skelet is intact. Tijdens de Tweede Wereldoorlog ontdekte een boswachter bij toeval de spookachtige locatie.
De aanvankelijke hypothese was dat een grote groep mensen getroffen was door een of andere catastrofe, zoals een heel zware storm. DNA-onderzoek van 38 skeletten maakte nu echter komaf met dat idee. Uit de genetische analyse blijkt immers dat de stoffelijke resten afkomstig zijn van afzonderlijke bevolkingsgroepen die op verschillende tijdstippen gedurende een tijdsspanne van ongeveer 1000 jaar aan het meer toekwamen. Dat blijkt uit een studie die werd gepubliceerd in het wetenschappelijk tijdschrift Nature Communications.
“We ontdekten dat de geschiedenis van het Roopkundmeer complexer is dan we ooit hadden gedacht”, zegt geneticus David Reich van de Harvard Medical School.
ShutterstockHet meer ligt vol met menselijke beenderen.
Verschillende origine
Tien jaar geleden onderzocht Kumarasamy Thangaraj, een geneticus van het CSIR Centrum voor Cellulaire en Moleculaire Biologie in India, het DNA van 72 skeletten uit het meer. Hij stelde vast dat sommige beenderen een lokale Indiase origine hadden, maar andere niet. Zo bleken sommige botten van Zuidoost-Aziatische afkomst te zijn.
Een internationaal team van een 25-tal archeologen, genetici en andere specialisten vergeleek nu het DNA van 38 skeletten uit het meer. Zij stelden vast dat de botten afkomstig waren van drie verschillende groepen: de grootste groep bestond uit 23 individuen met DNA dat vergelijkbaar is met dat van leden van de huidige Indiase bevolking.
Middellandse Zee
Het DNA van de tweede grootste groep, 14 individuen, bleek tot hun verbazing vergelijkbaar te zijn met dat van mensen die vandaag leven in Kreta en Griekenland. Het laatste individu had DNA dat wees op een Zuidoost-Aziatische afkomst.
“We waren bijzonder verrast door de genetica van de Roopkundskeletten”, zegt evolutiebioloog Éadaoin Harney van de Universiteit van Harvard. “De aanwezigheid van individuen met een afkomst die typisch in verband gebracht wordt met het oosten van het Middellandse Zeegebied suggereert dat Roopkund Lake niet alleen lokaal een belangrijke plek was, maar bezoekers aantrok uit de hele wereld.”
Tijdspanne van 1000 jaar
Nog verrassender was de aankomst van de groepen. Uit koolstofdatering blijkt dat de botten van Indiase afkomst dateren van de zevende tot de tiende eeuw. De twee andere groepen, uit het Middellandse Zeegebied en Zuidoost-Azië, dateren van tussen de 17de en 20ste eeuw.
De kans bestaat dat er in het meer nog niet nader onderzochte botten liggen die afkomstig zijn uit andere tijden en regio’s. De wetenschappers hopen nu dat verder onderzoek zal uitwijzen wat deze individuen naar het meer bracht en hoe ze aan hun einde kwamen.

'Storm Area 51' event pushes rural Nevada county to declare emergency
'Storm Area 51' event pushes rural Nevada county to declare emergency
Ed Komenda Reno Gazette Journal
LAS VEGAS, Nev. – Commissioners in Nevada's rural Lincoln County have voted to pre-sign an emergency declaration ahead of the "Storm Area 51" raid event that's so far drawn more than 2 million RSVPs on Facebook.
On Monday, the county board unanimously voted, 4-0, to approve the declaration in preparation for a mysterious affair that could draw thousands of curious visitors to the desert.
"We passed this with the caveat that this may or may not happen," said District D Commissioner Kevin Phillips. "We're just trying to do the best we can to prepare for something we know not of. We have no pickin' idea what we're going to face – if anything."
California resident Matty Roberts created the event – called "Storm Area 51, They Can't Stop All of Us" – in June after listening to an episode of the Joe Rogan Experience podcast. The tongue-in-cheek event scheduled for Sept. 20 quickly generated millions of accepted invitations.
Lincoln County is home to the town of Rachel, the self-proclaimed "UFO Capital of the World," located on State Route 375 – dubbed in 1996 the "Extraterrestrial Highway."
The actual Area 51 site is a classified military facility set inside a test and training range roughly the size of Connecticut. Intrigue surrounding the impenetrable desert compound for decades has fueled conspiracy theories and local lore about what exactly goes on there.
'See them aliens': Nearly 400K people have signed up for Facebook event to 'storm' Area 51
'Unified curiosity': After 'Storm Area 51' gets 2 million RSVPs, its creator announces alien-themed music fest
But it’s a mystery that’s now driving an unknown number of unknown people from unknown corners of the country to the Nevada hinterlands. Lincoln County leaders are using this preemptive emergency declaration as a beacon to state officials that there’s a chance more people will show up than local authorities can handle.
An emergency declaration allows the state to supply resources in the event the outpost of 5,200 people needs help.
"It's a smart chess play," Phillips said.
Air Force spokeswoman Laura McAndrews said in a statement to USA TODAY that military officials were aware of the event that aims to uncover what many people believe are conspiratorial secrets of the military installation in Nevada.
McAndrews didn't specify any security plans at the base, but she did warn those thinking of entering the area.
"The Nevada Test and Training Range is an area where the Air Force tests and trains combat aircraft," McAndrews said. "Any attempt to illegally access military installations or military training areas is dangerous."

Noodtoestand afgekondigd om bestorming Area 51. Hoe Nevada zich voorbereidt op een menigte waarheidszoekers
In Lincoln County in Nevada is uit voorzorg de noodtoestand afgekondigd in verband met de verwachte bestorming van Area 51.
Al meer dan twee miljoen mensen hebben zich aangemeld voor het Facebookevenement ‘Bestorm Area 51’ in september. Nog eens 1,5 miljoen mensen zijn geïnteresseerd.
Het is goed mogelijk dat duizenden nieuwsgierigen zullen afreizen naar de woestijn. Veel motels zijn al volgeboekt.
UFO-hoofdstad van de wereld
“We proberen ons zo goed mogelijk voor te bereiden op iets waar we niets over weten,” zei bestuurslid Kevin Phillips.
Matty Roberts uit Californië maakte het evenement in juni aan nadat hij een aflevering van de podcast van Joe Rogan had bekeken.
Het begon in eerste instantie als grap, maar de aanmeldingen bleven maar binnenstromen.
In Lincoln County bevindt zich Rachel, de zelfverklaarde ‘UFO-hoofdstad van de wereld’.
Niet zonder gevaar
De nabijgelegen militaire basis Area 51 wordt al decennia met complottheorieën omgeven. Zo zouden er onder meer UFO’s en lichamen van aliens worden bewaard.
Woordvoerster van de Amerikaanse luchtmacht Laura McAndrews zei tegen USA Today dat legerfunctionarissen op de hoogte zijn van het evenement.
Ze waarschuwde mensen om het gebied niet te betreden.
“De Nevada Test and Training Range is een gebied waar de luchtmacht gevechtstoestellen test,” zei McAndrews.
“Het betreden van militaire installaties of militaire trainingsgebieden is niet zonder gevaar,” voegde ze toe.
‘Biofluorescent World’ may not have the same cachet as Jurassic World, but it may be closer to reality … and it just might be the place where we finally find extraterrestrial life forms. A new study proposes that the exoplanets with the highest probability of hosting life forms are often hit with heavy doses of ultraviolet radiation and life there may develop the same protective mechanism that some undersea coral use on Earth to protect themselves – biofluorescence. The end result would be that these life forms would glow in soft blues, greens and other colors that could easily be picked up by telescopes trained to look for them. Will the catchphrase of the inevitable remake of everyone’s favorite extraterrestrial movie be “ET, put on a shade!”?
“Our first targets in the search for signs of life are orbiting nearby M stars, such as the planets in the Proxima Centauri, Ross-128, LHS-1140, and TRAPPIST-1 systems.”
In the latest edition of the Monthly Notices of the Royal Astronomical Society, Jack O’Malley-James, a research associate at the Cornell Center for Astrophysics and Planetary Science, describes how he and co-author Lisa Kaltenegger from the Cornell astronomy department decided where to look for glowing aliens. Those four M-stars are spot. Especially when they’re already peering at M-type stars. Also known as red dwarfs, those are the most common stars in our universe, and they happen to host a lot of planets in their Goldilocks zone.
Unfortunately for any planets orbiting them, they also emit solar flares that can engulf these planets with ultraviolet radiation, especially if they’re in the Goldilocks zone where life is most likely to develop. As the saying goes – if the radiation doesn’t kill it, it will make it stronger … or at least adaptable to it. That’s what some forms of coral do in shallow waters – absorb blue and ultraviolet photons and re-emitting them at longer wavelengths which just happen to be fluorescent. That’s bioflorescence — the emission of light by a substance that has absorbed light of a shorter wavelength. (FYI: bioluminescence is a chemical reaction that generates light and is independent of radiation.)
“If you and I would have evolved on such a world, we would probably glow too, as that would have had advantages in survival.”
Kaltenegger’s point in LiveScience is logical, but would there be enough of us glowing brightly so that we could be seen by telescopes in other solar systems? Possibly, if enough of us and all of the other life forms on Earth were biofluorescent. Of course, that’s not the case since we have an atmosphere that blocks most of the rays from us (and sunblock for the rest). O’Malley-James and Kaltenegger are hoping that planets orbiting nearby red dwarfs in their Goldilock zones will have enough bioflourcent beings to light up the planet, even briefly, so that one of our telescopes can pick it up. One of our future telescopes, that is. Our current models can’t pick it up – or they would have already.
What about when life forms from these glowing planets send their ships to Earth? Will we be able to spot them at night? Will they look at our pitiful non-glowing bodies with disdain?
