07 July 2010, 01:02 PM ET
A stellar black hole that releases a prodigious amount of energy from the most powerful pair of jets ever seen from such a cosmic object was recently discovered. But, the real surprise is what is created by those jets.
21 June 2010, 08:10 AM ET

18 June 2010, 12:11 PM ET
Scientists watched matter falling into a black hole for the first time.
02 June 2010, 12:02 PM ET
Most black holes spin in the same direction as their surrounding disc of debris. However, for the rare black hole that spins in the opposite direction, that deviance may produce the more powerful jets of radiation than seen in regular black holes.

A monster black hole has been flung from its home galaxy and is careening through space, according to a new study.
04 May 2010, 08:50 AM ET
Black holes might kill entire galaxies with blazing energy, dooming embryonic stars before they can get born.
03 May 2010, 07:48 AM ET
A pair of rare medium-sized black holes was spotted near the center of a nearby galaxy, but for some reason they haven't been swallowed up by the supermassive black hole lurking there.
27 April 2010, 08:08 AM ET
Our universe might have originated from a black hole that lies within another universe.
21 April 2010, 09:48 AM ET
NASA's Swift satellite detected its 500th gamma-ray burst on April 13, in an explosion in the Cassiopeia constellation.
25 March 2010, 02:06 PM ET
When two massive galaxies collide, they may form quasars, which are regions around giant black holes where matter is gobbled up and light is flung back into space.
12 February 2010, 01:00 PM ET
The backward spin of some black holes could create mysterious jets of plasma that control the fate of galaxies
28 January 2010, 01:55 PM ET
Small black holes mysteriously self-regulate, just like their supermassive cousins.
27 January 2010, 05:45 AM ET
A stellar-mass black hole strips material from its companion as they circle each other.
06 January 2010, 06:49 AM ET
New Chandra X-ray Observatory images and computer models show why the Milky Way black hole is starving.
21 December 2009, 08:21 AM ET
Mysterious dark matter may have helped the earliest stars shine.
18 December 2009, 10:25 AM ET
Super-powerful galactic overlords rearrange the contours of space itself in their local neighborhoods. Their blast-waves heat up - and hollow out - hundreds of thousands of light years of interstellar space.
18 December 2009, 10:18 AM ET
Which came first: Galaxies? Or the big black holes at their centers? Evidence from the Hubble Space Telescope's Deep Field images is persuasive.
17 December 2009, 11:42 AM ET
Humans may escape the death of their planet. But where do you run, in a universe where everything is expanding away from everything else?
17 December 2009, 11:41 AM ET
Another word for "time" is "change". When transformation stops, time ceases. Calculating the death date of the last black hole, which marks the end of Everything.
15 December 2009, 11:22 AM ET
Astronomers have estimated more precisely the distance to a black hole, finding the gravity well is much closer to us than assumed.
08 December 2009, 09:35 AM ET
The biggest black holes in the universe are also the most perplexing. Scientists have long been confused about just how the earliest, most massive black holes formed, but new evidence now suggests they could have originated inside giant cocoon-like stars.
02 December 2009, 05:49 AM ET
A flash of nearly 13 billion year-old light - discovered only recently by new astronomy techniques - reveals how the Universe has distributed ever more intricate elements throughout its history.
30 November 2009, 04:47 PM ET
Astronomers have long wondered which came first, the black hole or the galaxy around it. The leading theory holds that the two co-evolve, starting small and building over time.
24 November 2009, 09:58 AM ET
Supernovas make metals out of simpler elements. But it takes supermassive black holes to deliver them to the Cosmos. So, amazingly, these monsters are directly responsible for creating us.
10 November 2009, 05:29 PM ET
Black holes usually come in either the little or big variety, but astronomers have found new evidence that middleweight black holes exist too.
