| Cygnus X-1 Copyright David A. Hardy One of the first suspected examples of a black hole was Cygnus X-1. In 1972 a massive blue supergiant star in Cygnus was found to have an invisible companion which emitted X-rays. This was calculated to be 14 times as massive as the Sun – too massive to be a neutron star, so a black hole is the most likely explanation. Here it is seen pulling material away from its companion and becoming strongly heated; hence the X-rays. Excess gas is ejected in two very active jets above and below the disc.
