Supermassive black holes found at the centers of distant galaxies undergo huge growth spurts as a result of galactic collisions, according to a new study by astronomers at Yale University and the University of Hawaii. Their findings appear in the March 25 edition of Science Express. As massive, gas-rich galaxies in the distant universe collide, the central black hole feeds on gas that is funneled to the center of the merger. "As a result of the violent, messy collision, the black hole also...

Up to now, primitive black holes, which occupy the cores of active galaxies and were around as far back as the early days of the universe, only existed in astronomer's models. Researchers have now found two such gravitational monsters, however, which revealed themselves as brightly glowing quasars. Their light originates from a time when the universe was barely one billion years old - and we can see them now exactly as they appeared 12.7 billion years ago (Nature, March 18, 2010). A quasar is...

Two enormous black holes appear to be orbiting one another at the center of a faraway galaxy, formed by the collision of two separate galaxies, astronomers from the National Optical Astronomy Observatory (NOAO) in Tucson reported Wednesday. The two supermassive black holes are locked in orbit about 5 billion light years away from Earth, the scientists said.  One light year is the distance light travels in a year, approximately 6 trillion miles. Data from Apache Point Observatory in New...

WASHINGTON (Reuters) - A supermassive black hole appears to be homeless in the cosmos without a galaxy to nestle in, Hubble Space Telescope scientists reported on Wednesday. Most monster black holes lurk at the heart of massive galaxies, slurping up matter from the galactic center with a pull so strong that nothing, not even light, can escape. But a team of European astronomers reported in the journal Nature that a particular black hole some 5 billion light-years away has no evidence...

Supermassive Black Hole -- A Supermassive black hole is a black hole with a mass in the range of millions or billions solar masses. A supermassive black hole has some interesting properties differing from his low-mass cousins: -- The average density of a supermassive black hole can be very low, and actually can be lower than water's density. This happens because the black hole diameter increases linearly with mass, and consequently density drops much faster. -- Strong tidal...
