A brand new ‘Unicorn’ is the closest black hole to Earth

Astronomers have probably found the closest known black hole to Earth, a strange little object called “The Unicorn” that lurks just 1,500 light years away from us.

The nickname has a double meaning. Not only does the black hole candidate live in the constellation Monoceros (“the unicorn”), its incredibly low mass – about three times larger than the sun – makes it almost one of a kind.
