Musculoskeletal Robot Driven by Multifilament Muscles Resembles a Human’s Movements
Musculoskeletal Robot Driven by Multifilament Muscles Resembles a Human’s Movements
Researchers at the Suzumori Endo Robotics Laboratory at the Tokyo Institute of Technology have a different take on robotics in the form of a musculoskeletal robot that moves like a human.
Essentially, a fake skeleton covered in a bunch of cables, the musculoskeletal robot is powered by artificial multifilament muscles that function like real human muscles when electrical current flows through them.
Basically, the fake muscles can contract and expand similar to a real human’s movements thanks to the electrical current, even enabling the skeleton’s head to move around realistically.
At the moment, the Suzumori Endo humanoid can’t support itself, but the robot’s legs do contain the exact same number of muscles that a real human being’s legs use to walk.
The researchers hope that as technology advances and the musculoskeletal robot progresses, it will eventually be able to walk on its own and self-balance, similar to the ATLAS robot.

VIDEO: Complottheoreticus David Icke kruist degens met presentatoren over aliens en holle maan
VIDEO: Complottheoreticus David Icke kruist degens met presentatoren over aliens en holle maan
De bekende samenzweringstheoreticus David Icke kruiste vanochtend tijdens het Australische ontbijtprogramma Today de degens met presentatoren Karl Stefanovic en Lisa Wilkinson.
De Britse oud-sportverslaggever, die momenteel in Australië is voor zijn World Wide Wake Up Tour, claimt dat 9/11 een inside job was en dat aliens in het geheim onder ons leven in menselijke vorm.
Icke zei tijdens het programma dat er een kracht is die de menselijke beschaving manipuleert en die overal op aarde een andere naam heeft. “Als je hier onderzoek naar doet, en dat doe ik al 26 jaar, kom je tot de ontdekking dat al deze namen verwijzen naar dezelfde kracht,” zei hij.
Last Week Tonight with John Oliver: Conspiracies (Web Exclusive)
Wilkinson vroeg hem vervolgens over zijn kijk op de maan. “U denkt bijvoorbeeld dat de maan, onze maan, een uitgehold ruimtestation is?” vroeg ze. Icke antwoordde: “Sovjetwetenschappers opperden dit als eerste. Ze kwamen tot de conclusie dat de maan geen natuurlijke satelliet kan zijn en hol is.”
“De reguliere wetenschap kan niet verklaren waarom zo’n groot hemellichaam, groter dan Pluto, om zo’n kleine planeet kan draaien,” vervolgde hij. “Er zijn veel oude stammen die zeggen dat de maan hier gebracht is en dat er een tijd was waarin de aarde geen maan had.”
Stefanovic vond dat Icke zich ‘erg defensief’ opstelde. “Nee, ik erger me,” aldus Icke. “Ik erger me aan het feit dat de mainstream media en de meeste mensen door de verkeerde kant van een telescoop naar de wereld kijken.”
Let vooral op het buitengewoon intelligente (lees: tenenkrommende) gedrag van Stefanovic, dat tekenend is voor de manier waarop de mainstream media andersdenkenden benaderen.

In 2013 deed de Canadese oud-minister van Defensie Paul Hellyer een schokkende uitspraak: dat een federatie van buitenaardse rassen de mensheid in de gaten houdt en stuurt. Dat meldt televisiezender History.
Volgens sommigen is er genoeg bewijs te vinden voor deze bewering. Vrijwel iedere cultuur kent wel verhalen over keizers, koningen en farao’s die een groep van negen goden raadpleegden. Zelfs CIA-wetenschappers channelden in de jaren vijftig een buitenaardse groep die ‘De Negen’ werd genoemd. Deze groep zou hier zijn om gebeurtenissen op aarde te beïnvloeden, aldus de zender.
In 1952 zette de Amerikaanse medicus Andrija Puharich een speciaal laboratorium op dat deel uitmaakte van een topgeheim overheidsprogramma. In het lab werden experimenten gedaan met psychologische manipulatie en hallucinogene drugs. Eén van zijn proefpersonen was Uri Geller.
Niet-fysieke wezens
Eén van de meest controversiële aspecten van zijn onderzoek had betrekking op channeling, het contact leggen met niet-fysieke wezens. In december 1952 werd contact gelegd met een groep entiteiten die ‘De Negen’ werd genoemd.
“De Negen zeiden dat ze een eindeloze aanwezigheid waren,” legt Nick Pope uit, die ruim 20 jaar werkzaam is geweest voor het Britse ministerie van Defensie. “Ze hielden de mensheid naar eigen zeggen al vanaf het begin in de gaten.”
Star Trek
In zijn privéwoning besprak dr. Puharich zijn onderzoek met mensen uit de toplagen van de samenleving. Iemand die actief deelnam aan die sessies was Gene Roddenberry, de bedenker van de bekende tv-serie Star Trek. De serie zou zijn geïnspireerd op de mysterieuze groep ‘De Negen’.
De Prime Directive, een richtlijn uit de populaire serie die actieve bemoeienis met minder ontwikkelde soorten verbiedt, zou bijvoorbeeld zijn voortgekomen uit de sessies van dr. Puharich.
“Als we in de gaten worden gehouden door aliens, is het erg aannemelijk dat ze niet openlijk in de voortuin van het Witte Huis landen vanwege zo’n Prime Directive,” aldus Pope.
Doorgewinterde Argentijnse ufoloog ontdekt ‘buitenaardse piramide’ in Grote Oceaan
Doorgewinterde Argentijnse ufoloog ontdekt ‘buitenaardse piramide’ in Grote Oceaan
De Argentijnse ufoloog Marcelo Irazusta zorgt voor consternatie. Op de bodem van de Grote Oceaan heeft hij iets vreemds ontdekt. Mogelijke verklaringen variëren van een gecrashte UFO tot de resten van een oude beschaving. Dat schrijft het Russische staatspersbureau Sputnik.
De Argentijnse onderzoeker, die zich specialiseert in buitenaardse levensvormen, heeft naar eigen zeggen op Google Earth een UFO gevonden voor de kust van Mexico. Het object is 5,5 kilometer lang en lijkt qua vorm nog het meest op een vliegtuig.
Andere ufologen zijn er niet zo zeker van dat hij op een UFO is gestuit. Scott Waring, die verschillende boeken over het onderwerp heeft geschreven, vertelde aan het Argentijnse persbureau Telam dat hij er een piramide in ziet.
Atlantis
“Het is een perfect gevormde piramide, die een doorsnee heeft van meer dan 14 kilometer,” zei hij. Volgens hem gaat het om de grootst bekende piramide. Het bouwsel is zo indrukwekkend dat het moet zijn gemaakt door leven van een andere planeet, aldus Waring. “Enkel aliens zijn in staat om zoiets te bouwen.”
De beelden van de piramide zijn inmiddels bijna een half miljoen keer bekeken. Telam meldt dat het volgens sommigen gaat om de resten van het mythische eiland Atlantis, dat werd beschreven door de Griekse filosoof Plato. Anderen zeggen dat het bouwwerk is achtergelaten door de Maya’s of Azteken.
NASA
Marcelo Irazusta is een doorgewinterde ufoloog. Eerder dit jaar publiceerde hij een video waarin buitenaardse bases op de maan en op Mars te zien zouden zijn, schrijft Sputnik. Samen met ufoloog Sandra Elena Andrade heeft hij er bij de NASA op aangedrongen om daar onderzoek te doen naar de mogelijkheid van buitenaards leven.
“De schokkende ontdekking heeft op internet geleid tot fascinerende discussies,” schreef Andrade. “Wat gaat NASA doen? Komen ze met een plausibele verklaring of houden ze zich stil?”
V-shaped UFOs reported hovering over Memphis highway
V-shaped UFOs reported hovering over Memphis highway
A Tennessee witness at Memphis reported watching two V-shaped UFOs “hanging” in the sky over an interstate highway, according to testimony in Case 77441 from the Mutual UFO Network (MUFON) witness reporting database.
The witness was southbound along I-55 in Memphis near the Delta Refinery, pictured, when the UFOs were spotted hovering above on June 22, 2016.

The witness was driving to Memphis Airport along southbound I-55 at 3:30 a.m. on June 22, 2016, near the Delta Refinery when the incident occurred.
“As we got closer, I slowed and rolled my window down and stuck my head out to get a better view,” the witness stated.“It was not moving nor making any sound. I could not believe what I was seeing.”
The object was double the size of a large jet.
“Seemed to be over twice the size of a 737 and just hanging there in the sky. Shaped like a V made of two rectangles, cut at the ends to make a point.”
The witness decided not to stop along I-55 to take pictures as it was not safe.
(Credit: Google)
The witness first thought to pull over and dig a camera out of luggage in the vehicle, but then thought it unwise to do that on an expressway.
“The traffic was light, but it was all tractor trailer rigs. I tried adjusting my left rear view mirror, but could not see it even when I looked back. Then, off to my right, some distance away, we saw the same light pattern hanging in the southern sky, too far away see any distinguishable features.”
The witness attempted to sum up the location and size of the object.
“To the best of my memory, I would guess the object was 1,000 to 1,500 feet up, gray in color with white lights along the lower outer edges except for one red light at the back. I would guess that legs of the V to be 30-feet to 50-feet square and 200-feet to 300-feet long with the span at the back of the V about 150-feet. There were two protrusions that I could make out clearly on the bottom of the closest leg. One was a cylindrical-shaped and the other was like an inverted fender well or a spare tire carrier. I am still befuddled about what it was. I swore to myself I will never travel again without a camera ready. To this day, I want to go back and look, camera ready.”
The objects were 200 to 300 feet long.

The witness was at home at 9:23 p.m. on July 4, 2016, when the object was first seen and identifying it quickly resolved into wondering if it was a UFO or a drone.
“We all saw the object high in the sky and we filmed the object using a 60x HD camcorder,” the witness stated. “My wife looked out the window and saw an object with bright light high in the sky. We thought the object could be a sophisticated, large drone, possibly military.”
But reviewing the video frame-by-frame the object appears to spin and then disappear.

“The object hovered stationary for several minutes. Using my HD video camera zoomed in at 60x I could see an A-frame shape for each structure; a red and green light in the middle, and three bright, white lights on top. It began spinning and then disappeared as shown frame-by-frame on the video.”
The object then returned a few minutes later in the same location, but facing a different direction.
“It hovered stationary again and then disappeared. The video zoom did not resolve well, but the object appeared to change color all at once to red before it disappeared. We were excited to see the object even if it turns out to be just a drone. My wife posted the video clip to her Facebook account and friends were shocked. Some said it was just a drone, but others did not. We lost sight of the object because it disappeared.”

A Connecticut witness at Bridgeport reported watching a slow-moving, white craft at low altitude moving over Black Rock Harbor about 11 p.m. on July 2, 2016, according to testimony in Case 77451 from the Mutual UFO Network (MUFON) witness reporting database.
The witness was very familiar with Black Rock Harbor when the UFO moved low across the sky on July 2, 2016. (Credit: Google)
“The Fairfield fireworks had ended,” the witness stated.“The crowd was thinning out. The boats had all come back in. It was time for me to go fishing. I live on Long Island Sound. I fish every night from April to January. If it happens in the night sky I see it! Every moon. Every meteor shower. Every fireworks display.”
The witness was sitting in a spot facing the water.
“Two friends were standing up facing me with their backs to the water. I looked up to engage one friend in conversation. Over her left shoulder I saw a rather large, slow-moving, oval-shaped craft. It was illuminated white. It was blurred because it was flying in low cloud cover or possibly smoke hanging in the air from the fireworks.”
The oval-shaped craft was illuminated white.

The witness watched the object for about 10 seconds before it faded away into the cloud or smoke.
“It travelled slow and would have been following the shoreline heading south. As I’m watching this thing I’m going through the Rolodex in my brain sorting through memories and experiences and what I know already. Airplanes and helicopters have clear projected lights as well as red blinking lights. They also create sound. This was illuminated white and silent.”
The witness even considered someone shining a spotlight into the sky.
“But the light would reflect off the cloud or smoke. None of that either. I’ve been here 25 years and no plane or helicopter has ever flown this bearing, barring search and rescue. There was no search and rescue that night. I eliminated everything I thought it could be based on my experiences. What I am left with is actually a white, walnut-shaped, slow and low moving craft over the shoreline of Black Rock Harbor. Has anyone else reported this?”
The slow-moving craft moved over the shoreline.

Here Football great Aaron Rodgers talks about his believe in UFOs and aliens and how about his experiences that make him believe this way. Is a fantastic step forward when a celebrity comes forward to talk about their UFO story and share it with the world. It tells the public, hey, be like me...tell the truth, theres nothing to be afraid of anymore. Just awesome. Jump to the 9 min mark in the video. Scott C. Waring www.ufosightingsdaily.com News states: There’s a lot of great stuff from Packers quarterback Aaron Rodgers during his appearance on HBO’s “Any Given Wednesday” with Bill Simmons, but the part where he says he saw a UFO and “heard” fighter jets following it is easily the most fascinating part of this 10-minute video. Rodgers first talked about UFO sightings in March, but it’s pretty safe to say a lot of people didn’t hear about it. Fast forward to the 9:00 mark to hear Rodgers tell his story. The first time Rodgers brought up UFO’s was on the “You Made it Weird” podcast with Pete Holmes. Here’s the link, the UFO talk starts at the 14:45 mark. “There was a weird siren in the distance,” Rodgers said. “So we go outside – it was a snowy night – and we went outside and it was one of those kind of bright nights, where it’s overcast, but there’s enough light from the moon to see things and the next thing you know, we saw something in the sky.” He compared what he saw to one of the huge ships from the movie “Independence Day.” “And it goes out of sight and we look at each other and go, ‘What in the (expletive) was that?'” Rodgers said. And thirty seconds after it had gone out of sight he and two others heard the “definitive sound” of a fighter jet, just like in “Top Gun,” Rodgers explained.

A man snapped of what many UFO enthusiasts considered as a spectacular photo above the World Trade Center Ground Zero buildings in New ork.
The witness chose not to be named in his report filed with the Mutual UFO Network (MUFON), one of the biggest organization that investigates UFO reports around the world.
In a MUFON report, the witness said he was with his wife in WTC Ground Zero. He captured several random photos of the building – three pictures in a minute.
The couple did not notice any anomaly in the photos throughout their holiday trip. When they viewed the photos after the holiday, they found a strange object flying above.
The reporting witness said that they didn’t see the UFO with their naked eyes when they were visiting the WTC. He believes that is not an ordinary aerial object in the sky. He thinks the United States government won’t permit any conventional vehicles to fly above there.
He suggests that it can be an undetected vehicle or a UFO. One photo of the witness shows colourful circles and the next one shows a UFO that appears to replace the rings. In photo number 3, no light and no UFO can be seen.
The witness wants professionals to analyse the images, the main reason he sent them along with his reportto MUFON.

Saturn Moon Enceladus' Plumes May Resemble Earth's 'Lost City'
Saturn Moon Enceladus' Plumes May Resemble Earth's 'Lost City'

Saturn's intriguing moon Enceladus could resemble Earth's "Lost City," a network of hydrothermal vents in the Atlantic Ocean where life survives despite cold and darkness.
Earth is the only planet in the solar system with liquid water on its surface, but many of the solar system's moons and dwarf planets seem to hide their oceans beneath their crust. Saturn's moon Enceladus, on the other hand, isn't content to keep things underground; large gashes at the moon' south pole spurt liquid from the interior into space. The access provided by these vents makes it a tempting spot for scientists hoping to search for signs of life outside of Earth.
"We want to use chemistry as our guide to looking for signs of life," said Christopher Glein, a research scientist at the Southwest Research Institute in Texas. Glein discussed the history of human understanding of Enceladus last month at the 228th American Astronomical Society meeting in San Diego, California. There, he compared that moon's undersea environment to the Lost City hydrothermal field in the Atlantic Ocean, where hot water bursts from the ocean floor and life thrives in the otherwise desolate depths.

"Is there life beyond Earth?" Glein asked. "Our generation is now poised to begin to tackle and search for some answers."

"Candy to life"
When NASA's Voyager 2 mission flew by Enceladus in 1981, it revealed terrains far smoother than the rocky satellites seen before. The polished landscape suggested that something unusual was happening on Enceladus. But it wasn't until NASA's Cassini mission caught a glimpse of plumes spurting from the southern pole that scientists realized just how unusual the moon is. Today, scientists have identified 101 individual jets shooting out from the large "tiger stripe" fissures at the southern pole, which average 80 miles (130 kilometers) long (a significant stretch of the moon's surface).
At first, scientists thought the water feeding the tiger stripes came from a small sea beneath them. In 2015, Cassini's gravitational data revealed that the tiny moon instead housed a global ocean under its entire surface. The bright plumes carried tiny particles of water-ice mixed with water vapor from beneath the surface, Glein said. But the real mystery was what else the stripes might carry.
No one expected Enceladus to spurt samples into space, so Cassini didn't carry any instruments designed to sample the plumes. But the team found a way to use the instruments they did have to study some of the material, and so they guided the spacecraft to dive through the plumes and taste their chemistry.
"What we found was truly remarkable," Glein said.
Cassini discovered salts, which couldn't have come from a slowly melting ice source.
"A liquid ocean that rapidly flash freezes — that does the job," Glein said.
Cassini also revealed that the plumes had a pH of 11.12, making them more basic than acidic. In comparison, Earth's rainwater ranks at 5.6 and seawater around 8. Glein put the plumes' pH in the domain of cleaning agents like Windex.
"It's not quite to drain cleaner, but it's getting there," he said.
One way to raise the pH, and heat the plumes in the process, is the process of serpentinization, which occurs when liquid water reacts with magnesium- and iron-rich minerals. The changed rocks, often green, are loaded with bases, and can lead to a rise in pH, Glein said. Although such rocks are rare on the surface, they can be found tucked away in the mantle or in collections of rocks and minerals on the seafloor.
One of the most famous sites of serpentinization is Earth's Lost City, a collection of hydrothermal vents near the Mid-Atlantic Ridge. First identified in 2000, the vents are heated primarily by the changing rocks rather than by mantle beneath the surface. According to the National Oceanic and Atmospheric Administration, serpentinization can raise temperatures as high as 260 degrees Celsius (550 degrees Fahrenheit), and drives the hydrothermal system of the Lost City.
In addition to providing heat, the Lost City's vents spout methane- and hydrogen-rich fluids to the surface, and are thriving environments for life.
"Hydrogen is like candy to microorganisms," Glein said. And the vents are "just packed with minerals," he added —the combination of chemical, biological and geological processes makes spots like the Lost City vents prime sites for life to have evolved. If Enceladus boasts similar vents powered by a process like serpentinization, life could originate there, as well, Glein said.
The best evidence for vents on the tiny moon comes from farther away, in Saturn's E ring, which is where material ejected from Enceladus can end up. Material from the plumes easily escapes the moon's gravity, which is only 1 percent of Earth's, and falls around the ringed planet. Samples of the ring material revealed silicate particles that scientists traced back to the moon. According to Glein, vents in a subsurface ocean could produce similar silicates.
That doesn't quite cinch the case, though. "We have evidence of hydrothermal vents, but we haven't found the hydrogen yet," Glein said.
The dramatic fractures on the surface of Enceladus known as tiger stripes provide direct access to the ocean beneath.

"One of the great mysteries"
Before Cassini arrived at Saturn, scientists thought Enceladus was too small to maintain water in a liquid state, so the plumes came as a surprise. Exactly how the moon keeps its water liquid remains uncertain.
"There's a serious energy crisis on Enceladus," Glein said, referring to the energy required to keep that water liquid. "It's one of the great mysteries of planetary science moving forward."
Since Cassini first identified the geysers on the small moon, scientists have tried to identify how water remains liquid instead of freezing to ice. One possibility is that the interior of the moon is heated as Saturn tugs and releases it. Another option is that the ocean contains some form of antifreeze, rather than pure water. Chemical reactions between the ocean and the rock, like the serpentinization described above, could also produce the necessary heat.
Enceladus is a tiny moon. With an average radius of 156 miles (252 km), it's only about one-seventh the size of Earth's largest satellite. According to Glein, that makes the moon the smallest geologically active body in the solar system, and the only one to boast water-based cryovolcanism, where icy liquid instead of hot lava oozes from the crust. Coming from such a small world, the eruptions are enormous.
"We don't have volcanic eruptions on Earth that span over an entire Earth diameter," Glein said.
Saturn's satellite is far less dense than the moon or Earth, with roughly half its material consisting of water. Enceledus' icy exterior makes it incredibly reflective.
"If it was our moon, it would be blindingly bright in the sky," Glein said.
The southern hemisphere may not be the only place to ever house plumes, Glein said Geological mapping of the moon's northern latitudes suggests relics of gashes similar to the tiger stripes in the south, he said. As the liquid water freezes, it could close off one set of stripes and open others.
Referring to a famous geyser at Yellowstone National Park in Wyoming, he said, "I think Old Faithful has finally met its match in Cold Faithful."
A team of physicists from the UK and Canada have created a computer simulation that points to the Big Bounce theory rather than the Big Bang. They state that the universe we know today is the sequel to a previous one that collapsed. They state that despite this periodical collapse, the universe does not completely get destroyed because the effects of quantum mechanics preserves it, allowing it to spring back to what it is today.
ETERNAL BOUNCE
A team of physicists from the UK and Canada have provided a simulation that supports the theory that our universe did not start out the way the Big Bang model proposes, but rather expanded to its current state after a period of contraction—a cycle dictated by the Big Bounce Theory.
The Big Bounce theory states that the universe follows a cycle of contraction and expansion, repeated infinitely. According to this theory, the universe did not begin with a violent explosion, but rather formed as a previous universe expanded or “bounced” back collapsing during the contraction phase of this endless cycle.
One of the main issues that had prevented the Big Bounce theory from securing its validity is that there was no proposed explanation as to how the universe could expand back after its full collapse. The team’s simulation suggests that once the universe reaches its smallest point, the common laws of physics governing our daily environment are abandoned and the rules of quantum mechanics come into play. The effects of quantum mechanics would preserve of the universe, keeping it from destruction and allowing the emergence of another universe like the one we’re in today.
“Quantum mechanics saves us when things break down,” explains team member Steffen Gielen, from Imperial College London. “It saves electrons from falling in and destroying atoms, so maybe it could also save the early Universe from such violent beginnings and endings as the Big Bang.”
NEXT UP: GALAXIES
Using quantum mechanics in a computer simulation, the team was able to formulate how the universe could spring back from deflation, even with only radiation and a little matter remaining in it.
“The big surprise in our work is that we could describe the earliest moments of the hot Big Bang quantum mechanically, under very reasonable and minimal assumptions about the matter present in the Universe,” said team member Neil Turk, from the Perimeter Institute for Theoretical Physics in Canada. “Under these assumptions, the Big Bang was a ‘bounce’, in which contraction reversed to expansion.”
What’s next for this simulation is to find out if the entities within the universe, such as galaxies, can come into existence under these circumstances. As technology evolves, the chances thatquantum computers could finally catch up with the enigmas of the universe are looking better and better.

In Cosmic First, Scientists Spy a Star's Snow Line
In Cosmic First, Scientists Spy a Star's Snow Line

For the first time, astronomers have caught a glimpse of the water snow line around a star — the point in the young star's orbiting disk of debris where snow and ice first appear.
Normally, that boundary huddles too close to the star for astronomers to see it, but this particular star had a sudden burst of brightness that superheated its disk, obliterating ice further out than usual.

Bright burst
A newborn star is surrounded by an orbiting pancake of gas, dust and debris— the raw materials from which its complement of alien planets will eventually form. Most stars are hot enough to evaporate the water in that disk up to about 280 million miles (450 million kilometers) from the center, which is three times the distance from Earth to the sun, allowing ice to coat the debris beyond. (The water skips its liquid phase because of the extremely low pressure in space.)
The star V883 Orionis, found 1,350 light-years from Earth in the constellation Orion, burns quite a bit hotter than usual — it is in the midst of a burst of brightness and heat from a sudden influx of new material. That let the star vaporize ice all the way out to 3.7 billion miles (6 billion km), or the average distance at which Pluto orbits the sun, catching researchers by surprise. The far-out boundary let them see the water snow line in radio wavelengths withthe Atacama Large Millimeter/submillimeter Array (ALMA), a collection of radio telescopes in Chile that makes up the world's biggest ground-based observatory.
"The ALMA observations came as a surprise to us," Lucas Cieza, an astronomer at Diego Portales University in Chile and the lead author of the new work, said in a statement. "Our observations were designed to image disk fragmentation, which is one of the proposed mechanisms for the formation of giant planets." The researchers didn't see any fragmentation; instead they saw an unexpected ring in the disk.

Planet builders
In a News & Views column tied to the new work, which was published in the journal Nature today (July 13), Brenda Matthews, an astronomer at the National Research Council of Canada who was not involved in the study, wrote that the water snow line is important in determining which planets form — rocky planets form within it, and gaseous planets form out past it.
"The fact that the location of the snow line can evolve with time has strong implications for planet formation," Matthews wrote. The rapid loss and gain of ice tied to changes in the star "would confound models that predict the slow formation of rocky planets within the snow line, and rapid gas-giant formation outside it."
When the star V883 Orionis suddenly heated up due to an influx of new material, the water snow line moved much farther out, meaning researchers could detect it with ALMA.

And simply seeing a snow line at all, which had been postulated but not spotted before, helps confirm that other stars have a similar swath of ice and snow to the one in the sun's early environment that led to our solar system's current collection of planets.
"The distribution of water ice around a young star is fundamental to planet formation and even the development of life on Earth," Zhaohuan Zhu, an astronomer at Princeton University and a co-author on the new work, said in the statement. "ALMA's observation sheds important light on how and where this happens in protoplanetary disks when young planets are still forming."
"We now have direct evidence that a frosty region conducive to planet formation exists around other stars," Zhu added.
Editor's Note: This article was updated to reflect the distance of the water snow line for most newborn stars, about 280 million miles (450 million kilometers).
New Type of Black Hole Spotted in the Early Universe
New Type of Black Hole Spotted in the Early Universe

Early clouds of gas and dust may have collapsed to form a huge single star that quickly became the seed for a supermassive black hole. In this image based on a supercomputer simulation, gas flows along filaments of dark matter. The first galaxies formed at the intersection of such filaments.

A bright galaxy in the early universe likely contains a mysterious kind of black hole that had previously existed only in theory, a new study suggests.
This probable "direct-collapse" black hole may help explain howsupermassive black holes — the light-gobbling behemoths that lurk at the hearts of most, if not all, galaxies — got their start, researchers said.
"The special aspect of this [direct-collapse] process is that it leads to the formation of a very massive 'seed' black hole in one go," study co-author Avi Loeb, chair of the astronomy department at Harvard University, told Space.com via email. "It is difficult to make such a giant black hole over such a short time if they start from low-mass seeds." [Images: Black Holes of the Universe]
Death by gluttony
When a massive star reaches the end of its lifetime, it can collapse inward on itself to form a black hole. These dense objects then grow by feeding on surrounding gas and dust, but the process can take time.
Indeed, it probably takes quite a while for such a small seed to grow into a supermassive black hole, which can contain billions of times more mass than the sun, scientists say. This poses a puzzle: Where, then, did the supermassive black holes in the early universe come from?
Some of these monsters existed only 750 million years after the Big Bang that created the universe, Loeb said. (Scientists know this because they have spotted quasars — incredibly bright galactic cores powered by supermassive black holes — of this vintage.)
"It is difficult to make such a giant black hole over such a short time if they start from low-mass seeds," Loeb said.
In 2003, Loeb and Volker Bromm of the University of Texas at Austin (UT Austin) — also a co-author of the new study — theorized that clouds of dust and gas in the early universe were so hot that they failed to fragment into multiple clumps of thousands of stars. Instead, such clouds likely created just a single massive star at the center, roughly 1 million times larger than "normal" stars, Loeb said.
Such gigantic stars would quickly consume all of the nearby gas and dust. Overeating would lead to a rapid demise; these stars would last only a few million years before collapsing into midsized black holes that could continue to feed, ultimately growing into the giants that lie at the centers of galaxies.
To stay so superhot, the gas at the heart of this process would need to be almost purely hydrogen and helium, without "heavier" elements to help cool it down. Since heavy elements are produced in the hearts of stars and then released during a supernova, such "direct-collapse black holes" could only form in the early universe, the researchers said. [The Universe: Big Bang to Now in 10 Easy Steps]
But there hadn't been much evidence for this idea — until now.
From prediction to reality
Last year, astronomers spotted a strange signal from a galaxy known as CR7, one of the most luminous objects in the early universe. Although the galaxy showed signs of temperatures greater than 180,000 degrees Fahrenheit (100,000 degrees Celsius) and signatures of helium atoms gaining and losing electrons — a process known as ionization — there were no signs of other elements.
"That makes the galaxy that we have discovered really unique, and ticks all the boxes for predictions for both first-generation stars or a direct-collapse black hole," David Sobral, an astrophysicist at the University of Lisbon in Portugal, told Space.com.
Sobral led the team of astronomers that identified irregularities in CR7 last year and other similar galaxiesmore recently. In their paper, they argued that, while CR7 could contain a direct-collapse black hole, the unusual signal favored a cluster of the universe's first stars.
"Regardless, the actual material — pristine gas — to make either first-generation stars or a direct-collapse black hole is essentially the same, and it is extremely exciting to finally start asking actual physical questions about the nature of the very early galaxies," Sobral said. "This goes way beyond the traditional approach of simply counting distant galaxies."
Sobral and other scientists will continue to observe CR7, with instruments such as NASA's Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array in Chile. But other research teams are investigating the galaxy's origin and evolution via computer modeling and other work.
Black Hole
Black holes are so bizarre, they sound unreal. Yet astronomers have found good evidence they exist. Test your knowledge of these wacky wonders.
Fabio Pacucci, a Ph.D. student at Scuola Normale Superiore in Italy, was part of one such team, whose research argued for the black-hole theory in a paper last year. But those researchers' observations of CR7 weren't definitive.
"Unfortunately, we do not see any X-ray emission from this source, which would be a smoking gun to say that it is a black hole," Pacucci said.
That's where Loeb and Volker come in. They're members of another research team, led by Aaron Smith of UT Austin, that sought to solve the mystery.
Smith and his colleagues developed what Smith called "a novel code" to simulate both the black-hole and the first-star scenarios using a supercomputer at UT Austin. The star scenario "spectacularly failed," Smithsaid in a statement, while the direct-collapse model held up.
"The evidence [for a black hole] is conclusive," Loeb told Space.com.
After predicting the existence of direct-collapse black holes more than a decade ago, Loeb is excited to see them confirmed by observations.
"It feels good to come up with an idea about how nature might work, but it is exhilarating to find out that nature really behaves the way you thought it does," Loeb said. "The experience is as rewarding as getting love back from a person you love."
Smith and his colleagues published their results last week in the journal Monthly Notices of the Royal Astronomical Society.
The Universe's First Galaxies May Light Up Its Dark Ages

A collection of newfound galaxies is illuminating how the early universe broke free from its Dark Ages. The family of galaxies may have played a role in the shift from a time when some light could not penetrate to an era of a transparent universe.
"Stars and black holes in the earliest, brightest galaxies must have pumped out so much ultraviolet light that they quickly broke up hydrogen atoms in the surrounding universe," David Sobral, an astrophysicist at Lancaster University in the United Kingdom, said in a statement. Sobral led an international team of scientists aiming to find several of these early galaxies using the Subaru and Keck telescopes in Hawaii and the Very Large Telescope in Chile. The results were presented today (Monday, June 27) at the National Astronomy Meeting in Nottingham, England.
"The fainter galaxies seem to have stayed shrouded for a lot longer," he said. "Even when they eventually become visible, they show evidence of plenty of opaque material still in place around them." [The Universe: Big Bang to Now in 10 Easy Steps]
In 2015, Sobral led a team that found the first two members of the collection, galaxies CR7 and MASOSA, which might contain the first generation of stars. Together with a third galaxy known as Himiko, discovered by a Japanese team, the presence of the trio of galaxies hinted that a large population of similar objects might exist.
The problem, however, is in spotting them. About 150 million years after the Big Bang kicked off the universe's existence (an event that took place 13.8 billion years ago), the universe was dense with neutral hydrogen that blocked the passage of certain wavelengths of light. As radiation from the earliest stars split apart hydrogen in what scientists call the "epoch of reionization," light began to slowly pass through the surroundings, bringing the Dark Ages to an end.
Each of the five newfound galaxies discussed in the presentation contains a large bubble of ionized (charged) gas around them, suggesting that they haven't managed to completely break free from the Dark Ages.
This timeline summarizes the evolution of the universe, with the Big Bang at left and about 2 billion years into the universe's existence at right. As reionization occurred, radiation emitted by the first stars and black holes cleared out the haze of neutral hydrogen.

"Our results highlight how hard it is to study the small, faint sources in the early universe," said co-author Sergio Santos, a graduate student at Lancaster University.
"The neutral hydrogen gas blocks out some of their light, and because they are not capable of building their own local bubbles as quickly as the bright galaxies, they are much harder to detect," he said.
The fifth of the faraway sources discovered, VR7, is named in tribute to astrophysicist Vera Rubin, who won the Gold Medal of the Royal Astronomical Society in 1996, becoming the first woman to win that award in over 150 years.
The young galaxies may be just a handful among the hundreds of thousands of ancient galaxies that might be spotted by future instruments.
"What is really surprising is that the galaxies we find are much more numerous than people assumed, and they have a puzzling diversity," Sobral said. "When telescopes like the James Webb Space Telescope are up and running, we will be able to take a closer look at these intriguing objects."
"We have only scratched the surface, and so the next few years will certainly bring fantastic new discoveries," he said.
Wereldbedreigende rampen: hoe eindigt het leven op aarde?
Wereldbedreigende rampen: hoe eindigt het leven op aarde?
Tim Kraaijvanger
Het is een feit dat het leven op aarde ooit eindigt. Alle soorten die vandaag de dag over onze planeet zwerven, bestaan vanaf dat moment niet meer. De grote vraag is: hoe eindigt leven? En vindt er op korte termijn een massa-extinctie plaats of hebben we nog even de tijd om een andere planeet te vinden?
In het boek ‘Wereldbedreigende rampen‘ somt auteur Bill McGuire verschillende scenario’s op. Hij is hoogleraar geofysische en klimaatdreigingen aan de University College in Londen en heeft dus veel ervaring op het gebied van wereldbedreigende rampen. Tijdens de rampen met de IJslandse vulkaan Eyjafjallajökull en de Indische tsunami adviseerde hij de Britse regering.
Jaarlijks sterven er gemiddeld 106.000 mensen door rampen. Het is niet makkelijk om in één klap ruim zeven miljard mensen uit te roeien. “Veel doemscenario’s van nog veel grotere onheilsprofeten dan ik gaan in werkelijkheid niet over totale ondergang”, schrijft McGuire. “In het ergste geval zou de mensheid flink worden gedecimeerd.” Maar ooit gaat het mis met onze planeet. “We moeten erop rekenen dat we ‘vroeg ten onder gaan’ (zoals John Leslie in zijn boek ‘The End of the World‘ formuleert) in plaats van ‘laat’. De klimaatverandering gaat steeds sneller, de bevolking groeit explosief en is alom verwikkeld in buitensporige conflicten. Al met al zou het grootse avontuur van het menselijk ras wel eens snel ten einde kunnen zijn, in plaats van voort te duren tot ver in de toekomst en de enorme ruimte van de Melkweg.”
KLIMAATVERANDERING IN NEDERLAND
Ook in Nederland merken we de gevolgen van klimaatverandering. De temperatuur neemt toe, waardoor we minder sneeuwwinters krijgen. De kans op een Elfstedentocht neemt af van twintig procent per jaar naar eens per achttien jaar. Een ander duidelijk kenmerk is de toename van neerslag.
Een oven… Klimaatverandering vormt absoluut een bedreiging. Verandert onze planeet in een diepvries of in een oven? “De wereld van 2100 zal warmer en extremer weer kennen”, voorspelt McGuire.”En dat betekent op z’n minst een veel onprettiger leven voor miljarden mensen. Bewoners van laaggelegen kuststreken krijgen vaker te maken met een stijgende zeespiegel, waardoor fatale overstromingen eerder regel dan uitzondering worden. Steeds meer mensen komen om van de honger, omdat de regens het ene jaar na het andere uitblijven. Enorme gebieden in Afrika en Azië raken in de greep van droogte en hongersnood die er het gevolg van is.”
Het helpt niet mee dat er steeds meer monden gevoed moet worden. “De aarde moet meer dan zeven miljard mensen voeden, kleden en in hun levensonderhoud voorzien. Naar verwachting zijn dit er in 2050 zo’n negen miljard.” Dit levert conflicten op. “Nu al leven 1,7 miljard mensen in landen waar de zoetwatervoorziening ontoereikend is. Over 25 jaar zullen dat er vijf miljard zijn. De strijd om voedsel en water vormt een aanzet tot economische migratie op een schaal waarbij alles wat we tot nu toe hebben gezien in het niet valt. Op veel plekken in de wereld zullen instabiliteit en conflicten het gevolg zijn.”
Zo ver reikte het ijs tijdens de laatste ijstijd.
…of een diepvries? De meter kan ook de andere kant opslaan. “Gelet op de Milankovic-cycli heeft het huidige interglaciaal zijn langste tijd gehad en stevenen we af op een heuse ijstijd”, zegt de hoogleraar. “Volgens sommigen is er slechts een trigger voor nodig: een plotselinge schok waardoor het klimaatevenwicht aan het wankelen wordt gebracht, waarna het kantelt naar een veel onvriendelijkere toestand.” Als de temperaturen gaan dalen, heeft dit grote gevolgen. “Hoe dan ook – onze nakomelingen krijgen het zwaar wanneer het ijs terugkomt. In Europa, Noord-Amerika, Rusland en Centraal- en Oost-Azië wordt het leven min of meer onmogelijk. De aarde is er tijdens een ijstijd niet op berekend om te voorzien in het levensonderhoud van 8-10 miljard mensen of meer. De mensheid zal sterk worden gedecimeerd door wijdverbreide hongersnood en oorlogen, maar zal ongetwijfeld overleven.”
Actie tegen klimaatverandering Het is gelukkig nog niet te laat om actie te ondernemen. “Maar dan moeten we wereldwijd onze levensstijl veranderen”, schrijft McGuire. “Geen wegwerpsamenleving meer, maar één die effectief en efficiënt gebruik van energie en grondstoffen bevordert en beloont. Het enige dat werkt is doortastend overgaan op duurzame ontwikkeling. Minder brandstof verbruiken, investeren in hernieuwbare energiebronnen, veel meer recyclen en plaatselijk produceren (bijv. stadslandbouw, red.).”
Supererupties Maar er is meer waar we voor op moeten passen. Denk bijvoorbeeld aan supererupties en reusachtige tsunami’s. Een gigantische uitbarsting in een uithoek van de wereld kan het klimaat veranderen, waardoor de samenleving ten onder gaat. “Maar liefst 450 miljoen jaar geleden – gedurende het Ordovicium – lijken as en gloedwolken in wat nu Noord-Amerika is alles te hebben weggevaagd over een oppervlak van een miljoen vierkante kilometer. Bovendien moeten er enorme hoeveelheden as en stof in de atmosfeer zijn beland.” Stel dat het een periode ‘donker’ blijft: hoe gaan we ons dan voeden? Ontwikkelde landen als Duitsland, de Verenigde Staten en Australië hebben slechts genoeg voorraad om de bevolking één, maar niet meer dan twee maanden te voeden. De kans dat iemand die nu leeft een supereruptie meemaakt, is 1 op 714. Het is onwaarschijnlijk dat een supereruptie alle mensen uitroeit, maar onze mondiale technologische samenleving blijft mogelijk niet intact.
Wereldwijd zijn er zo’n veertig supervulkanen. De caldera van Yellowstone getuigt van een superuitbarsting 640.000 jaar geleden.
Daarnaast zijn er nog reuzentsunami’s, die kunnen ontstaan wanneer vulkanen instorten. Dit gebeurt naar schatting eens per tienduizend jaar. Of aardbevingen, waardoor dichtbevolkte steden in ruïnes veranderen. Beide rampen zullen niet het einde voor de mensheid betekenen, maar er gaan wel veel levens verloren.
Gevaar van boven Het echte gevaar komt van boven. “Om de vijf minuten verbrandt een fragment ter grootte van een erwt in onze atmosfeer”, zegt McGuire. “Elke maand doet een homp ter grootte van een voetbal de hemel oplichten. Om de paar eeuwen botst de aarde met een object van veertig tot vijftig meter. Dit is groot genoeg om een stad weg te vagen.” Wanneer een object 1,5 tot twee kilometer groot is, dan is er sprake van een mondiaal probleem. Tientallen miljoenen mensen sterven waarschijnlijk direct, terwijl de rest van de mensheid kampt met de gevolgen van de inslag: meer stof in de atmosfeer en dalende temperaturen. Gelukkig is er ook hier hoop. “Als we lang genoeg van te voren weten dat een asteroïde ons gaat raken, kunnen we in bepaalde situaties het object weg duwen.”
Er is hoop Over honderd jaar leven er tussen de 3,2 miljard en 24,8 miljard mensen op aarde. Dit is afhankelijk van allerlei factoren. Misschien moeten we maar hopen dat de toekomstige aarde minder mensen huisvest, want de toekomst voor onze nakomelingen wordt warmer, onherbergzamer en armer aan grondstoffen. “Op de korte termijn krijgen we misschien de ene klap na de andere”, concludeert McGuire. “Maar mogelijk leren we onze omgeving koesteren in plaats van er roofbouw op te plegen, hier op aarde voordat de zon ons uiteindelijk opslokt. En misschien later in het zonnestelsel, melkwegstelsel en daarbuiten. Dan hebben we de tijd om bijna alles te doen en te zijn.”
