Black hole affecting galactic climate identified

Science Daily: Comets and Asteroids -

Researchers used NASA's Chandra X-Ray Observatory, launched and deployed in 1999 by Space Shuttle Columbia, to identify a powerful galactic blast produced by a giant black hole about 26 million light years from Earth. The black hole is the nearest supermassive black hole to Earth that is currently undergoing such violent outbursts.
