A space telescope scheduled for launch in 2007 will be sensitive enough to detect theoretical miniature black holes lurking within our solar system. In doing so, it could test an exotic five-dimensional theory of gravity that competes with Albert Einstein
21 June 2006, 01:08 PM ET
Contrary to what you might think, a black hole's gravitational tug isn't strong enough to send matter falling into its center. It's magnetism that provides the final nudge inwards, a new study finds.
20 June 2006, 08:00 PM ET
In this animation of GRO J1655-40, gas is being drawn from the surface of the normal star onto the black hole's rotating accretion disk. Magnetic fields cause some of the gas to fall onto the black hole, and light is emitted in the process.
29 May 2006, 07:10 AM ET
A distinctive feature of black holes is the discharge of narrow jets that shoot matter into space in a continuous stream near the speed of light. But NASA's Spitzer Space Telescope has recently found one of these jets around a dense stellar corpse known a

Astronomers have detected the closest supermassive black hole neighbors yet. The pair dance around each other from a distance of about 24 light years, closer than Earth is to the bright star Vega.
24 April 2006, 01:58 PM ET
A new study finds that black holes are the most fuel efficient engines in the universe. If they were cars, they could travel over a billion miles on a single gallon of gas.
24 April 2006, 06:40 AM ET
Doomsayers and Chicken Little types can now rest a little easier. Scientists say the chances of our planet being struck by high energy gamma ray burst are close to nil.
18 April 2006, 02:47 PM ET
The types of black hole mergers predicted by Einstein's general relativity have been accurately simulated with a computer model for the first time. The model could help scientists detect elusive gravitational waves that should be produced by such mergers.
18 April 2006, 09:00 AM ET
Hubble has captured the most detailed images to date of open star clusters in a small galaxy orbiting our Milky Way. Such clusters contain thousands of stars all created from the same material and are excellent laboratories for studying stellar evolution.
06 April 2006, 11:48 AM ET
The black holes leave trails like jet contrails, allowing astronomers to predict their union.
05 April 2006, 01:00 PM ET
The discovery of a debris disk formed in the aftermath of a supernova explosion helps explain how planets can form around dead stars.

Astronomers have learned a lot about our home galaxy in recent years. presents a New Tourist's Guide to the Milky Way.
24 January 2006, 06:21 AM ET
A black hole in the constellation Scorpius is emitting two X-ray frequencies that are identical to those detected nine years ago. The finding, predicted by Albert Einstein’s theory of general relativity, suggests the black hole has created a stable dent f
10 January 2006, 01:17 PM ET
Scientists have found the first strong evidence that the supermassive black holes at the hearts of some galaxies weren't born big, but grew to their monstrous mass through the mergers of smaller galaxies.
09 January 2006, 11:20 AM ET
A type of X-ray explosion found on neutron stars does not occur near black holes, scientists announced here today. The lack of explosions is strong evidence for the existence of a black hole event horizon, a theoretical boundary into which matter vanishes
