Six hundred million light years away, a pair of black holes spiral furiously about one another at the brilliant core of a starburst galaxy. »
Pierre-Simon Laplace lived from 1749 to 1827 and was busy the entire time. He wrote books, worked in politics, and figured out the secrets of the universe. One of those secrets he quietly withdrew from later copies of his books. Pity. »
Black holes have a rap for being hopeless vortexes of destruction, but what would really happen if you fell into one? According to Stephen Hawking, you might end up in another universe. »
There’s a lot going on in this brand new X-ray view of our galaxy’s center—but just what does all that sound, fury, and color mean?
Five billion years ago, a blazar abruptly flared, triggered an intense rain of gamma rays. Racing across the universe for millennia, they finally slammed into NASA’s Fermi satellite over several days this June, setting a new record for the most luminous high-energy object we’ve ever seen. »
There is a paradox in the universe: scientists believe that there are millions more giant black holes in the universe than we know about, and yet, if they are there, how would they remain hidden? It turns out they do so by hiding in something almost unbelievably common. »
Christopher Nolan’s Interstellar broke new ground in its scientifically accurate portrayal of black holes and wormholes. A scientific journal is now urging educators to feature the film in their classes when teaching such topics as general relativity.
The process by which stars form has been well established for decades. Then, in the 1990s, astronomers looked out on the universe and saw evidence everywhere telling them that they weren’t getting the whole picture. Stars were beginning to form, but then disappearing. How? »
We’ve been using the Hubble Space Telescope to watch a jet of material coming out of galaxy NGC 3862 for over twenty years. Only recently, after piecing together a string of pictures, have we seen what’s really happening.
By applying the rules of Einsteinian general relativity to data pulled in by the Pan-STARRS telescope, scientist have developed two distinct simulations of supermassive black hole mergers that are considered the best yet. »
Nothing lasts forever, not even black holes. According to Stephen Hawking, black holes will evaporate over vast periods of time. But how, exactly, does this happen?
Information can escape the clutches of a black hole, say researchers from Buffalo University. And incredibly, they say this information is not just gobbledygook — it can actually be deciphered to show what lies beneath. »
A black hole and its galaxy are locked in a cosmic struggle, evolving in tandem and balancing each other's growth. In this artist's recreation, you can see cosmic winds howling out of supermassive black hole PDS 456. These winds are so strong that they prevent the galaxy from forming new stars. »
If you were going to travel close to a black hole in order to study it, which type should you choose? Most people would probably pick a smaller black hole, because it seems easier to avoid. But that's a fatal mistake. Small black holes can be far more dangerous than big ones, due to a terrifying process called… »
Black holes are what happens when matter is packed so densely that it compresses into a singularity... but some of them are still as insubstantial as air. If you think that's weird, it gets weirder. You make can make these ultra-light black holes even less dense by adding mass. »
Astronomers attempting to monitor a cloud of gas reacting to the black hole at the center of our galaxy got a huge surprise: A giant x-ray flare erupting from that black hole, the largest one ever detected. »
You probably already knew today is Black Hole Friday. To celebrate, NASA and other agencies have been posting black hole stuff. Like the above, an artist's conception of a black hole five times the mass of the one at our galaxy's center, in a superdense galaxy 1/500th the diameter of our own, the M60-UCD1 dwarf galaxy. »
Call it Orphan Black: Astronomers believe they've discovered a supermassive black hole that was kicked out of its home galaxy during a collision with another galaxy. Originally thought to be a supernova, the rogue black hole is adrift in interstellar space, some 2,600 light-years away from its host galaxy's core. It's… »
For years, astronomers have been fascinated and perplexed by what appears to be a massive cloud of gas and dust hurtling towards the black hole at the center of the galaxy. A team from UCLA now say they've finally figured out what it is. »
