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.

Black holes may not be bald after all. In a challenge to traditional models of the universe's gravitational monsters, new research suggests black holes could be quite "hairy," with more tangled features than previously believed.

A proposed mathematical proof that outlines the way information behaves in coded messages may have implications for black holes. The proof suggests that the radiation spit out by black holes may retain information on the dark behemoths.

Hubble and Chandra Space Telescopes combined data to produce these views of Sagittarius A*. Less than 1% of the hot gas around this black hole will actually 'fall' into it.
29 August 2013, 02:00 PM ET
The Milky Way's giant black hole turns out to be a messy eater. Of all the gas that falls toward it, 99 percent gets spewed back out into space, new observations show.

Launched in 2008, NASA's Fermi Gamma-ray Space Telescope has given scientists the ability to explore high-energy processes associated with a number of cosmic phenomena: black holes, solar flares, rapidly spinning neutron stars, & super nova remnants.

A newly discovered way to determine the spin of supermassive black holes could help shed light on the evolution of these bizarre objects and the galaxies they anchor. Astronomers used a European spacecraft to estimate one black hole's rotation rate.

Physics cannot describe what happens inside a black hole. There, current theories break down, and general relativity collides with quantum mechanics, creating what's called a singularity, or a point where the equations spit out infinities.
