NASA to Send Microsoft’s Virtual Reality Headset to International Space Station


NASA is sending Microsoft’s virtual reality headset to the International Space Station (ISS) to beam back to Earth what astronauts see in space.

NASA and Microsoft are teaming up to develop Sidekick, a new project using commercial technology to empower astronauts aboard the ISS.

Sidekick uses Microsoft HoloLens to provide virtual aid to astronauts working off the Earth.

A pair of the devices is scheduled to launch on SpaceX’s seventh commercial resupply mission to the station on June 28.

“HoloLens and other virtual and mixed reality devices are cutting edge technologies that could help drive future exploration and provide new capabilities to the men and women conducting critical science on the International Space Station,” said Sam Scimemi, director of the ISS programme at NASA Headquarters in Washington.

“This new technology could also empower future explorers requiring greater autonomy on the journey to Mars,” said Mr Scimemi.

The goal of Sidekick is to enable station crews with assistance when and where they need it. This new capability could reduce crew training requirements and increase the efficiency at which astronauts can work in space.

“Sidekick is a prime example of an application for which we envisioned HoloLens being used – unlocking new potential for astronauts and giving us all a new perspective on what is possible with holographic computing,” said Alex Kipman, technical fellow, Windows and Devices Group at Microsoft.

NASA and Microsoft engineers tested Project Sidekick and the Microsoft HoloLens aboard NASA’s Weightless Wonder C9 jet to ensure they function as expected in free-fall in advance of their delivery to the microgravity environment of the space station.

Sidekick has two modes of operation. The first is “Remote Expert Mode,” which uses Skype to allow a ground operator to see what a crew member sees, provide real-time guidance, and draw annotations into the crew member’s environment to coach him or her through a task.

Until now, crew members have relied on written and voice instructions when performing complex repair tasks or experiments.

The second mode is “Procedure Mode,” which augments standalone procedures with animated holographic illustrations displayed on top of the objects with which the crew is interacting.

This capability could lessen the amount of training that future crews will require and could be an invaluable resource for missions deep into our solar system, where communication delays complicate difficult operations.

From his perch on the International Space Station, astronaut Terry Virts has been taking some beautiful photos of Earth and space and sharing them on social media.

“Looking down into the eye – by far the widest one I’ve seen,” he tweeted. “It seemed like a black hole from a Sci-Fi movie.”

imrs

According to AccuWeather.com, Super Typhoon Maysak is one of the strongest cyclones in history during the months of January, February and March. It has slammed several Micronesian islands, killing 5 people, and is now on its way to the Philippines. As of early on April 1, Maysak had sustained winds of 240 kph (150 mph), equivalent of a Category 4 hurricane. Gusts as high as 390 kph (180 mph) are possible with this storm.

The typhoon is expected to weaken, but still poses a threat to the islands in its path:

Black Hole 12 Billion Times Bigger Than the Sun Discovered


Interstellar-team-and-black-hole

Scientists say they have discovered a black hole so big that it challenges the theory about how they grow.

The scientists were initially reluctant to classify it as a black hole because it was too bright, its luminosity equal to the brightness of 420 trillion suns. Most of the people do not believe black holes to be bright, though they can be. This is particularly so because black holes suck everything inside them but just before that there is tremendous friction which produces a lot of light.

Scientists said this black hole was formed about 900 million years after the Big Bang.

But with measurements indicating it is 12 billion times the size of the Sun, the black hole challenges a widely accepted hypothesis of growth rates.

“Based on previous research, this is the largest black hole found for that period of time,” Dr Fuyan Bian, Research School of Astronomy and Astrophysics, Australian National University (ANU).

“Current theory is for a limit to how fast a black hole can grow, but this black hole is too large for that theory.”

The creation of supermassive black holes remains an open topic of research. However, many scientists have long believed the growth rate of black holes was limited.

Black holes grow, scientific theory suggests, as they absorb mass. However, as mass is absorbed, it will be heated creating radiation pressure, which pushes the mass away from the black hole.

“Basically, you have two forces balanced together which sets up a limit for growth, which is much smaller than what we found,” said Bian.

The black hole was discovered a team of global scientists led by Xue-Bing Wu at Peking University, China, as part of the Sloan Digital Sky Survey, which provided imagery data of 35 percent of the northern hemisphere sky.

The ANU is leading a comparable project, known as SkyMapper, to carry out observations of the Southern Hemisphere sky.

Bian expects more black holes to be observed as the project advances.

Wormhole to another galaxy may exist in Milky Way

A giant doorway to another galaxy may exist at the centre of the Milky Way, a study suggests.

Scientists believe that dark matter at the centre of our galaxy could sustain a wormhole that we could travel through.

Wormholes are areas where space and time are being bent so that distant points are now closer together.

Einstein predicted them in his theory of General Relativity but nobody knows how they could be held open so that someone could travel through. Most scientists believe that It is extremely unlikely they could exist naturally in the universe. It would take a huge mass, like a Neutron star, to create a bend in time which could bend space time enough to meet another tunnel on the other side. No natural examples have ever been detected.

“If we combine the map of the dark matter in the Milky Way with the most recent Big Bang model to explain the universe and we hypothesise the existence of space-time tunnels, what we get is that our galaxy could really contain one of these tunnels, and that the tunnel could even be the size of the galaxy itself,” said Professor Paulo Salucci.

“But there’s more. We could even travel through this tunnel, since, based on our calculations, it could be navigable. Just like the one we’ve all seen in the recent film ‘Interstellar“‘.

He said the research was surprisingly close to what was depicted in director Christopher Nolan’s movie, for which theoretical physicist Kip Thorne provided technical assistance.

“What we tried to do in our study was to solve the very equation that the astrophysicist ‘Murph’ was working on,” said Prof Salucci. “Clearly we did it long before the film came out.”

 Wormholes bend space-time to allow distant regions to meet

Any wormholes existing in nature have previously been assumed to be microscopic pinpricks in the fabric of space-time.

But the one possibly lying at the centre of the Milky Way would be large enough to swallow up a spaceship and its crew.

Prof Salucci added: “Obviously we’re not claiming that our galaxy is definitely a wormhole, but simply that, according to theoretical models, this hypothesis is a possibility.”

Other “spiral” galaxies similar to the Milky Way – like its neighbour Andromeda – may also contain wormholes, the scientists believe.

Theoretically it might be possible to test the idea by comparing the Milky Way with a different type of nearby galaxy, such as one of the irregular Magellanic Clouds.

In their paper, the scientists write: “Our result is very important because it confirms the possible existence of wormholes in most of the spiral galaxies ..

“Dark matter may supply the fuel for constructing and sustaining a wormhole. Hence, wormholes could be found in nature and our study may encourage scientists to seek observational evidence for wormholes in the galactic halo region.”

The theory was published in the journal Annals of Physics.

A Pair of Black Holes Could Soon Collide And Destroy Their Galaxy


latest

One black hole is not to be messed with, let alone two. Astronomers have discovered what appears to be two supermassive black holes just one light-year apart, setting up a collision so massive it could be release as much energy as 100 million supernovas and destroy it’s inside galaxy . Yep.

A Supermassive Black Hole is the largest type of black hole, on the order of hundreds of thousands to billions of solar masses and are found in the center of almost all massive galaxies.In the case of the Milky Way, the Supermassive black hole is believed to correspond with the location of Sagittarius A*(At the center).

Thankfully, the black holes are far away in a remote galaxy called PG 1302-102. The collision itself, if astronomers have done the calculations right, will happen in the next million years. That’s a pretty unfathomably long time for humans, but just a blink of an eye in cosmic time.

Astronomers are excited about the discovery because a pair of black holes could yield valuable information about theorized but never directly detected gravitational waves. Gravitational waves are ripples in space-time that exist according to Einstein’s theory of general relativity. If the two black holes collide, most of the released energy will be in the form of gravitational waves, literally bending the fabric of space-time.

But for now, the pair of black holes still need to be 100 percent confirmed. When two black holes so far away are close to one another, astronomers on Earth can only see it as a particular flicker of light. Astronomers need to rule the flicker out as a statistical anomaly. Still, in the long history of the universe, black holes have almost certainly collided before. Destroying whole galaxies in one fell swoop is not just science fiction.

‘Perfect Storm’ Suffocating Star Formation around a Supermassive Black Hole

High-energy jets powered by supermassive black holes can blast away a galaxy’s star-forming fuel — resulting in so-called “red and dead” galaxies: those brimming with ancient red stars yet little or no hydrogen gas available to create new ones.

Now astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered that black holes don’t have to be nearly so powerful to shut down star formation. By observing the dust and gas at the center NGC 1266, a nearby lenticular galaxy with a relatively modest central black hole, the astronomers have detected a “perfect storm” of turbulence that is squelching star formation in a region that would otherwise be an ideal star factory.

This turbulence is stirred up by jets from the galaxy’s central black hole slamming into an incredibly dense envelope of gas. This dense region, which may be the result of a recent merger with another smaller galaxy, blocks nearly 98 percent of material propelled by the jets from escaping the galactic center.

“Like an unstoppable force meeting an immovable object, the molecules in these jets meet so much resistance when they hit the surrounding dense gas that they are almost completely stopped in their tracks,” said Katherine Alatalo, an astronomer with the California Institute of Technology in Pasadena and lead author on a paper published in the Astrophysical Journal. This energetic collision produces powerful turbulence in the surrounding gas, disrupting the first critical stage of star formation. “So what we see is the most intense suppression of star formation ever observed,” noted Alatalo.

Previous observations of NGC 1266 revealed a broad outflow of gas from the galactic center traveling up to 400 kilometers per second. Alatalo and her colleagues estimate that this outflow is as forceful as the simultaneous supernova explosion of 10,000 stars. The jets, though powerful enough to stir the gas, are not powerful enough to give it the velocity it needs to escape from the system.

Complex life may be possible in only 10% of all galaxies

The universe may be a lonelier place than previously thought. Of the estimated 100 billion galaxies in the observable universe, only one in 10 can support complex life like that on Earth, a pair of astrophysicists argues. Everywhere else, stellar explosions known as gamma ray bursts would regularly wipe out any life forms more elaborate than microbes. The detonations also kept the universe lifeless for billions of years after the big bang, the researchers say.

“It’s kind of surprising that we can have life only in 10% of galaxies and only after 5 billion years,” says Brian Thomas, a physicist at Washburn University in Topeka who was not involved in the work. But “my overall impression is that they are probably right” within the uncertainties in a key parameter in the analysis.

WHAT IS GAMMA RAY BURST 

Gamma-ray bursts (GRBs) are flashes of gamma rays associated with extremely energetic explosions that have been observed in distant galaxies. They are the brightest electromagnetic events known to occur in the universe.Bursts can last from ten milliseconds to several minutes. A typical burst releases as much energy in a few seconds as the Sun will in its entire 10-billion-year lifetime. But all observed GRBs have originated from outside the Milky Way galaxy.

Scientists have long mused over whether a gamma ray burst could harm Earth. The bursts were discovered in 1967 by satellites designed to spot nuclear weapons tests and now turn up at a rate of about one a day. They come in two types. Short gamma ray bursts last less than a second or two; they most likely occur when two neutron stars or black holes spiral into each other. Long gamma ray bursts last for tens of seconds and occur when massive stars burn out, collapse, and explode. They are rarer than the short ones but release roughly 100 times as much energy. A long burst can outshine the rest of the universe in gamma rays, which are highly energetic photons.

Black holes are one of the strangest objects in the universe, preventing anything from escaping their grip – even light.

Now astronomers have discovered something even more peculiar about these enigmatic objects; they are aligned with each other over distances stretching billions of light-years

The remarkable observations were made by the Very Large Telescope (VLT) in Chile, which found an eerie alignment between enormous interstellar objects called quasars.

Quasars are galaxies with very active supermassive black holes at their centres. They shine more brightly than all the stars in the rest of their host galaxies put together.
