Astronomers have discovered what is thought to be the closest black hole to Earth.
The black hole was found by experts at the European Southern Observatory (ESO). It is only 1000 light-years from our planet.
That might sound very far away, but the closest black hole found until now is V616 Monocerotis or A0620-00. It is located about 3,500 light-years away.
What is a black hole?
Black holes are formed when a dying star collapses inward under the pressure of its own weight. This leads to something called a supernova, a star’s extremely powerful explosion.
Black holes are places in space where the pull of gravity is so strong that even light can’t escape it! This is what makes them invisible.
