Biggest Known Black Hole in the Universe!
Astronomers have identified the biggest known black hole in the universe. It is 6.4 billion times more massive than the Sun and lurking 60 million light-years away at the centre of a giant galaxy. The galaxy, called Messier 87 or M87, is a popular target for backyard stargazers in the constellation of Virgo and was suspected to contain a supermassive black hole. Now one of the world's most powerful computers has worked out that the cosmic cannibal is up to three times more massive than thought.
