Black Hole Emits Ferocious Winds With the Energy of a Trillion Suns

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. » 2/19/15 8:00pm 2/19/15 8:00pm

Here's Why Small Black Holes Are More Dangerous Than Big Ones

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… » 1/27/15 11:00am 1/27/15 11:00am

The More Mass You Add To Black Holes, The Less Dense They Get

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. » 1/21/15 9:25am 1/21/15 9:25am

The Largest X-Ray Flare Ever Just Erupted From The Center Of Our Galaxy

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. » 1/06/15 10:20am 1/06/15 10:20am

Happy Black Hole Friday!

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. » 11/28/14 5:00pm 11/28/14 5:00pm

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… » 11/20/14 4:00pm 11/20/14 4:00pm

​We Finally Know What That Weird Cloud Is At The Center Of Our Galaxy

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. » 11/04/14 2:30pm 11/04/14 2:30pm

You Know About A Supernova. What About An "Unnova"?

The supernova is a well-publicized and frightening phenomenon. There's also a phenomenon known as an "unnova." You don't want it in your backyard any more than you want a supernova. » 9/19/14 6:20am 9/19/14 6:20am

A Black Hole Doesn't Die -- It Does Something A Lot Weirder

Black holes are basically "game over, man," for anything that gets too close to them, but they aren't invincible. In fact, they're always in the process of self-destructing. We'll look at how they fizzle out, and see if we can help them do it faster. » 9/09/14 11:28am 9/09/14 11:28am

What Would It Be Like To Fall Into A Black Hole?

Let's say you happened to fall into the nearest black hole. What would you experience and see? And what would the rest of the Universe see as this was happening? » 9/07/14 9:00am 9/07/14 9:00am

New 'Quantum Bounce' Theory Explains How Black Holes Become White

Some cosmologists speculate that black holes end their lives by transforming into their exact opposite — so-called 'white holes' that pour all the material they gobbled up back into space. A new theory based on quantum gravity could explain how this is possible. » 7/21/14 10:30am 7/21/14 10:30am

Are Black Holes All Shaped Like Doughnuts?

A new study puts the unified model of black holes, a.k.a the doughnut model, on trial and concludes that black holes are (disappointingly) perhaps not all shaped like a box of glazed donuts flung into the air. So what are they shaped like? » 5/22/14 1:58pm 5/22/14 1:58pm

The First Known Binary Supermassive Black Hole In An Ordinary Galaxy

For the first time ever, astronomers have detected a pair of supermassive black holes at the center of an inactive galaxy. The unique objects were discovered because they ripped apart a star when the ESA's observatory just happened to be looking in the right direction. » 4/23/14 7:20am 4/23/14 7:20am

What's The Purpose Of The Universe? Here's One Possible Answer

It's tempting to think of the universe as a meaningless repository for celestial objects like planets and stars. But an intriguing theory suggests there's much more to the cosmos than meets the eye — and that black holes play an integral role in what our universe is actually trying to achieve. » 4/18/14 11:07am 4/18/14 11:07am

What Happens When Two Black Holes Collide?

We know a few things about what happens when a black hole encounters another object in space. But what would happen if that object was, in fact, also a black hole? » 4/02/14 4:20pm 4/02/14 4:20pm

Ask A Theoretical Physicist About What Goes On In Black Holes!

Chris Adami, a theoretical physicist and computational biologist, is here today to take our questions about what goes on in black holes, information theory, and his proposed solution to the black hole information paradox posed by Stephen Hawking. » 4/02/14 10:24am 4/02/14 10:24am

A Solution To Stephen Hawking's Black Hole Paradox

Earlier this year, Stephen Hawking proposed a radical reformulation in how we define black holes — but this explanation still left a big unanswered question to how black holes work. Now, a physicist says he's cracked that problem. » 3/26/14 9:45am 3/26/14 9:45am

Distant supermassive black hole spins at half the speed of light

By magnifying a region of space 6 billion light-years away, astronomers have directly measured the spin of a distant black hole — and holy crap do these things ever rotate quickly. » 3/05/14 1:41pm 3/05/14 1:41pm
