A New Mission Will Search for Ripples in Spacetime

In the distant reaches of the Universe, exploding stars and supermassive black holes are bending the very fabric of spacetime. It’s hard to wrap our brains around such tremendous forces, but we may be able to quantify them, in the form of gravitational waves. A new European Space Agency mission marks humanity’s first… »9/03/15 1:45pm9/03/15 1:45pm

This Shower of Gamma Rays Is from a Flaring Blazar 5 Billion Years Ago

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. »7/12/15 1:40pm7/12/15 1:40pm

We May Have Dramatically Misunderstood the Shapes of Black Holes

Even if you didn’t see Interstellar, you’ve probably heard about how black holes have an “event horizon” — and once you pass it, you’re mashed into multi-dimensional mush. But now, some physicists believe we got it all wrong. Black holes are more like fuzzy balls of cotton, with no event horizons at all. »6/24/15 4:30pm6/24/15 4:30pm

The Original Black Hole For Interstellar Was Too Confusing

One of the many reasons why Interstellar was such a wonderful movie was that it used genuine scientific equations to show what happens in the vicinity of a black hole. But, just like the actors in front of the camera, it seems the black hole also got a little make up to make it more presentable for the big screen. »2/13/15 7:32am2/13/15 7:32am

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 3:15pm1/27/15 3:15pm

Here Are Two Galaxies With Supermassive Black Hole Hearts Colliding

Hey there, human, want to feel some awe? Look at this newly released NASA image set of two galaxies, each with a supermassive black hole at its heart, colliding in a violent spiral of star stuff. Space is awesome, and thanks to improved telescope technology, we're seeing more and more of it every day. »1/09/15 11:15am1/09/15 11:15am
