Astronomers Weigh Biggest Black Hole In The Universe
The biggest black hole in the Universe has been weighed by astronomers.
The monster celestial object is 18 billion times more massive than our own Sun, says a team from Finland - six times larger than the previous record.
The object, called OJ287, is orbited by a smaller black hole, which allowed its mass to be measured very accurately.
