Scientists using the National Aeronautics and Space Administration's Hubble Space Telescope have found the most compelling evidence yet produced for the existence of stupefying massive objects called black holes. Saying they now have a chance to resolve the debate as early as 1994, they released space telescope photographs of a swirling disk of dust, shooting jets of energy across 88,000 light-years of space.

The Hubble Space Telescope has confirmed for the first time the existence of a supermassive black hole, ending a decades-long quest for definitive proof, astronomers announced Wednesday.

NASA's Swift spacecraft has captured what scientists believe to be the "birth cry" of a black hole caused by the collision of two neutron stars a billion light-years from Earth. The discovery, announced Tuesday, is the best evidence so far that scientists may have found what causes short bursts of high-energy gamma rays, one of the most powerful sources of electromagnetic radiation in the universe.

Black holes, those fearsome galactic traps from which not even light can escape, may not be quite so terminally destructive after all, according to physicist Stephen Hawking. The author of "A Brief History of Time" now believes some "information" sucked into black holes escapes over time, contradicting some of his most famous work on the phenomenon. Hawking will present his findings at a scientific conference in Ireland next week, New Scientist magazine said.

This is a very contemporary story with a happy ending, though it was first turned into an old-fashioned bureaucratic ordeal for everyone concerned. Lisa Beckel of Los Angeles is now the legal mother of Charlotte and Annie Beckel, 15-month-old twins born last year after her husband, Graham Beckel, contributed the sperm with which the fertile eggs of a surrogate mother from Temecula were inseminated. Lisa Beckel is infertile.

For two decades, Stanford University physicist Leonard Susskind battled cosmologist Stephen Hawking over the behavior of black holes. Hawking said that when black holes eat their fill, they disappear, taking with them everything they consumed over their billions of years of existence. Susskind found this idea so disturbing that he publicly declared war -- a conflict he describes in his new book, "The Black Hole War."

Astronomers have pinpointed with unprecedented accuracy an immense black hole with a mass of more than 2 million suns at the center of the spiral of stars that is the Milky Way galaxy. Researchers at UCLA, led by Andrea Ghez, used the Keck telescope in Hawaii to measure tiny differences in the orbits of stars around the estimated center of the galaxy, near a point called Sagittarius A.

A powerful X-ray telescope has captured the super-massive black hole in the center of our Milky Way galaxy in the act--the act of snacking. For the first time, astronomers have observed a sudden and powerful X-ray flare coming from the direction of the voracious black hole. They believe the X-rays burst forth as the black hole gobbles up matter that comes near it.

Giant "blobs" of material have been discovered around a mysterious object near the center of the Milky Way Galaxy, leading scientists to believe they may be getting their best look yet at one of the most baffling objects in the universe--a black hole. It isn't possible to actually see a black hole, and no one has been able to prove that they exist, because a black hole would be so dense that even light would not escape its gravity.

UC San Diego scientists have discovered a second huge source of gamma rays in the Milky Way, a black hole or a neutron star that is spewing out enough radiation to power 50,000 suns. Reporting to the American Astronomical Society meeting in Seattle, research physicist Michael S. Briggs said the object is about 1,800 light-years away from Earth. This is much closer than the so-called "Great Annihilator," the gamma ray source that is believed to be a black hole near the center of the galaxy.
