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.
13 November 2013, 01:01 PM ET
Scientists found evidence of nickel and iron in the superfast jets emitted by a relatively small black hole, suggesting that "normal" matter plays a bigger role in these enigmatic structures than does exotic antimatter.

An extremely powerful radio telescope in Chile peered deeply into the universe and captured an incredible sight: an ancient black hole chowing down on a massive snack.
16 October 2013, 06:00 AM ET
Using the Atacama Large Millimeter/submilimeter Array in Chile, astronomers probed the supermassive black holes that are at the center of most galaxies, principally to analyze the molecular gas their massive gravity wells propel into powerful jets.

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.
20 September 2013, 10:50 AM ET
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.

Using the Hubble Space Telescope, researchers have glimpsed a monster black hole disgorging a high-speed, spiraling jet of superheated plasma that looks like a slinky stretching and reforming in outer space.

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.
