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.

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.

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

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
