Monster Black Holes May Lurk All Around Us (yahoo.com)

Taco Cowboy quotes a report from Yahoo News: Astronomers have stumbled upon a supermassive black hole in an unexpected corner of the Universe, implying these galactic monsters are much more common than once thought, a study said Wednesday. The giant, with an estimated mass 17 billion times that of our Sun, was discovered in a relative desert, astronomers from the University of California, Berkeley, wrote in the journal Nature. "While finding a gigantic black hole in a massive galaxy in a crowded area of the Universe is to be expected -- like running across a skyscraper in Manhattan -- it seemed less likely they could be found in the Universe's small towns," said a university statement. Big, star-rich galaxies where supermassive black holes had previously been found, are very rare. Smaller ones like the NGC 1600 galaxy housing the newly-discovered whopper, are much more common, but were not previously thought to be appropriate host. "So the question now is: 'Is this the tip of an iceberg?'" said study co-author Chung-Pei Ma. "Maybe there are a lot more monster black holes out there that don't live in a skyscraper in Manhattan, but in a tall building somewhere in the Midwestern plains." The largest supermassive black hole spotted to date tipped the scales at about 21 billion solar masses, said the study authors.
