... If the mass of the collapsing star is more than three solar masses, however, no force can prevent it from collapsing completely to become a black hole. What is a black hole? Mini black holes . ... For Further Reading About Black Holes A black hole is a region of space in which the pull of gravity is so strong that nothing can escape. ... A black hole with a mass less than three solar masses would not form on its own; its gravity is too weak to cause it to completely collapse in on itself. ...

Astronomers have found a radio pulsar with a companion at least 11 times the mass of the Sun - the most massive pulsar companion known. The identity of the companion is uncertain: it may be a massive late-type (red) star, a massive but compact blue star, or possibly a black hole. ... The probability of this late-type star being there by chance, and not being the pulsar companion, is only about 1.3%," says team member Dr. Fernando Camilo of Columbia University. ... So what can the companion be? ...
