Black Hole Candidate Cygnus X-1
Cygnus X-1 is one of the best candidates for a black hole. It is a binary star system, discovered because it is one of the brightest X-ray sources in the sky. Data indicates that a compact object in the system is too massive to be a neutron star, suggesting it is a black hole.
