Hole at the centre of the Galaxy

May 1991
New Scientist;5/25/91, Vol. 130 Issue 1770, p22
Reveals that a mysterious source of gamma rays located near the center of our Galaxy is probably just a common black hole. Previous belief that the hole was probably a `supermassive' black hole; Work of astronomers at the AT&T Bell Laboratories in Murray Hill, New Jersey; More.
