28 January 2014, 03:39 PM ET
On the heels of his bombshell claim that black holes — as scientists have traditionally thought of them — may not exist, Stephen Hawking will tell the story of his life in a new documentary that premieres tonight (Jan. 29) at 10:00 p.m. EST on PBS.
28 January 2014, 03:12 PM ET
Famed astrophysicist Stephen Hawking has shaken up the popular science world with his newest study about the basic nature of black holes, but is his idea revolutionary? Some scientists aren't convinced.
28 January 2014, 12:05 PM ET
To resolve a paradox between quantum mechanics and general relativity, Stephen Hawking has released a new paper arguing that light can, in fact, escape from black holes eventually, doing away with the notion of an event horizon.
25 January 2014, 09:15 AM ET
Black holes are mysterious objects in space where not even light can escape. But what are they really? Can we even ever truly know?
25 January 2014, 09:02 AM ET
On reading a new paper by Stephen Hawking that appeared online this week, you would have been forgiven in thinking the world-renowned British physicist was spoofing us. Hawking's unpublished work declares: 'There are no black holes.'

This fascinating space wallpaper is an artist's concept of the MWC 656 system, which consists of a massive "Be" star and a companion black hole.

An interstellar spacecraft could conceivably be powered by the radiation emitted by a tiny, manmade black hole. Here's a look at what it would take to turn this ambitious idea into reality.
15 January 2014, 01:01 PM ET
Astronomers have found a quiescent black hole orbiting a massive, fast-rotating 'B-emission' star, suggesting that these strange binary systems may be common throughout the Milky Way galaxy.

The incredible luminosity of a black-hole system known as ULX-1 may force a rethink of the leading theories that explain how some black holes radiate energy, researchers said.
21 November 2013, 02:59 PM ET
When a massive star runs out of nuclear fuel, it collapses under its own weight and forms a black hole. The black hole shoots jets of particles through the star at nearly the speed of light and astronomers believe they create the gamma-ray bursts.

A planet-hunting NASA spacecraft has detected no sign of moon-size black holes yet in the Milky Way galaxy, limiting the chances that such objects could make up most of the "dark matter" that has mystified scientists for decades.
