VLA reveals new object near supermassive black hole in famous galaxy
Charlottesville VA (SPX) May 24, 2017
Pointing the Very Large Array (VLA) at a famous galaxy for the first time in two decades, a team of astronomers got a big surprise, finding that a bright new object had appeared near the galaxy's core. The object, the scientists concluded, is either a very rare type of supernova explosion or, more likely, an outburst from a second supermassive black hole closely orbiting the galaxy's primary, central supermassive black hole. The astronomers observed Cygnus A, a well-known and often-studied galaxy ... read more
