The closest black hole to Earth was thought to be 1,560 light-years away - but a new study suggests there could be one around 150 light-years away.
This discovery implies that there ought to be many dormant black holes spread across the Milky Way galaxy, the home of Earth.
Astronomers studying what they thought was a double star system 1,000 light years from Earth in the southern constellation Telescopium stumbled on what must be a stellar mass black hole.
