CAMBRIDGE, Mass., June 4 (UPI) -- U.S. astronomers say they've seen evidence a massive black hole is being ejected from its host galaxy at several million miles per hour.
"It's hard to believe that a supermassive black hole weighing millions of times the mass of the sun could be moved at all, let alone kicked out of a galaxy at enormous speed," said Francesca Civano of the Harvard-Smithsonian Center for Astrophysics, who led the study.
