Biggest stellar-mass black hole discovered

BEIJING (ANN): An international team of scientists led by China has discovered a king-size, stellar-mass black hole in Earth's "cosmic backyard" containing the mass of 70 suns. It is the biggest known of its kind and roughly three times bigger than what scientists previously thought was possible, said researchers on Thursday (Nov 28).

The discovery challenged astronomers' understanding of the formation models for black holes of its class, and provided a new way to find similar black holes in the Milky Way galaxy that may lead to new theories for black hole astrophysics and stellar evolution.
