NASA just saw something come out of a black hole for the first time ever

NASA just saw something come out of a black hole for the first time ever
Wed, Nov 04, 2015 12:03pm You don’t have to know a whole lot about science to know that black holes typically suck things in, not spew things out. But NASA just spotted something mighty strange at the supermassive black hole Markarian 335. Two of NASA’s space telescopes, including the Nuclear Spectroscopic Telescope Array (NuSTAR), miraculously observed a black hole’s corona “launched” away from the supermassive black hole. Then a massive pulse of X-ray energy spewed out. So, what exactly happened? “This is the first time we have been able to link the launching of the corona to a flare,” Dan Wilkins, of Saint Mary’s University, said. NuSTAR’s principal investigator, Fiona Harrison, noted that the nature of the energetic source is “mysterious,” but added that the ability to actually record the event should provide some clues about the black hole's size and structure, along with (hopefully) some fresh intel on how black holes function.

The simplest explanation of why we should care about gravitational waves Before a team of scientists announced this week that they had detected gravitational waves for the first time ever — a blockbuster, Nobel-worthy discovery — I called up Cliff Burgess. Burgess is a theoretical physicist at McMaster University in Ontario. Throughout his career, he has authored hundreds of papers on the hardest problems in science: supersymmetry, string theory, wormholes, and dark energy, to name a few. My question to him was simple: Why are astronomers and physicists so excited about this?

Scientists have created a single chart that illustrates the circle of life with every known species on Earth In 1582, Richard Mulcaster, headmaster of the Merchant Tailors’ school, wrote that “our English tung is of small reatch, it stretcheth no further than this Iland of ours.” It didn’t stay that way. Today, English is spoken by more than a billion people all over the world. It is a colorful, vibrant, and diverse tongue that long has picked up words from the many languages with which its speakers have come into contact. Here are five words that illustrate the English language’s fascinating history.

NASA researchers are working on a laser propulsion system that could get us to Mars in 3 days Despite how far we've come in space exploration, one thing still holding us back from interstellar travel is our slow spacecraft. While we're able to propel particles to close to the speed of light in the lab, we're struggling to even accelerate spacecraft to beyond 3 percent of that. With our current technology, it's estimated it'll take humans around five months to reach Mars. But NASA scientist Philip Lubin is working on a system where lasers propel spacecraft with giant sails to the Red Planet in as little as three days. Much like Bill Nye's much-hyped solar sail, this 'photonic propulsion' system relies on the momentum of photons - particles of light - to move forward.

Incredible New Map Of The Milky Way Released One of the largest studies of our galaxy has just been completed. The ATLASGAL survey has mapped a huge swathe of cold dust and gas distribution in the Milky Way in order to understand how and where stars form. The survey has so far produced 70 scientific papers, and in the latest publication, astronomers combined the survey data with observations from the European Space Agency's Planck satellite. The paper, which appeared in Astronomy & Astrophysics, detailed the location of dense star-forming regions and established a precise star-formation rate for our galaxy: The Milky Way forms 13 stars the mass of the Sun every 10 years. The project was possible thanks to APEX, the Atacama Pathfinder EXperiment telescope, in Chile, a precursor to the advanced Atacama Large Millimeter/submillimeter Array (ALMA), which is studying the universe at wavelengths between infrared and radio.

businessinsider We got a present from the Juan de Fuca Plate, which is subducting under the North American Plate: a slow earthquake! Did you even know an earthquake could be slow? We're used to thinking of earthquakes as events that happen over seconds to a few minutes and produce a lot of shaking, but some earthquakes actually mosey along over hours or days, their trembling so gentle only seismometers can recognize it. One of these earthquakes started in the Cascadia Subduction Zone on December 21st and has been making its slow way south from Vancouver Island, British Columbia, Canada ever since. Astronomers Detect Host Galaxy of Fast Radio Burst for the First Time An international team of astronomers reported today that they had tracked down the location of a so-called fast radio burst (FRB), a mysterious and rarely detected burst of energy from space that appears as a short flash of radio waves to telescopes on Earth.

uk.businessinsider The universe is so vast it's almost impossible to picture what it might look like crammed into one field of view. But musician Pablo Carlos Budassi managed to do it by combining logarithmic maps of the universe from Princeton and images from NASA. He created the image below that shows the observable universe in one disc. Researchers discover the largest structure in the universe, and its HUGE! Researchers discover the largest structure in the universe, and its HUGE! Scholars have discovered a giant empty space in the universe where there are 10 billion galaxies missing. This incredible discovery could provide the first evidence for the existence of exotic physics which are absolutely unknown to modern science.

This Is What Supercontinent Pangea Looks Like Mapped With Modern Borders Imagine traveling from China to Antarctica, crossing through Canada, Brazil and India – without setting foot in any water. Unfortunately, you’ve missed your chance long ago as the supercontinent of Pangea no longer exists. But thanks to the illustrative talents of Massimo Pietrobon, you can see how Pangea may have looked before the epic landmass started ripping itself apart 200 million years ago to form the continents and countries of the world today. Image Credit: Massimo Pietrobon Surrounded by a superocean called Panthalassa, the bulk of Pangea was in the southern hemisphere, unlike how the continents are spread out now. Evidence for Pangea has been found in similar fossils recently discovered in South Africa, India and Australia, such as the therapsid Lystrosaurus and similar rock forms seen between the eastern coast of South America and the western coast of Africa.

There's A Powerful And Mysterious Signal Coming From The Core Of The Milky Way Dark matter is one of the greatest revelations in modern physics. Even though it hasn’t been directly detected yet, we know that it makes up around five-sixths of the total matter in the universe, binding much of it together in dramatic ways. It is this matter that stops galaxies from being torn apart as they spin. As a new study published in the journal Physics of the Dark Universe notes, dark matter can also be destroyed. A signature of dark matter’s annihilation could potentially reveal what it was composed of in the first place, and this team of researchers from Harvard University think they’ve found one right in the heart of our own Milky Way. Scientists are still debating what dark matter may actually be composed of, and one recent suggestion implies the particles are so dense that they are on the verge of becoming miniature black holes.

Astronomers watch black hole burp after eating a star Scientists have for the first time witnessed a black hole swallow a star and then quickly eject a flare of stellar debris moving at nearly light speed. Astrophysicists tracked the star—about the size of our sun—as it shifted from its customary path, slipped into the gravitational pull of a supermassive black hole, and was sucked in, says Sjoert van Velzen, a Hubble fellow at Johns Hopkins University. “These events are extremely rare,” says van Velzen, lead author of the study published in the journal Science. “It’s the first time we see everything from the stellar destruction followed by the launch of a conical outflow, also called a jet, and we watched it unfold over several months.”
