... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

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? ...
