Black holes
Black holes form when a body in the Universe has gravity so strong that it pulls in everything around it, even light, which is why a black hole appears black. They can range in size, from the size of an atom to supermassive black hole like the one at the centre of our Milky Way, which has the mass of 4 million suns and is the size of a few million Earths. This means the one thing black holes all have in common is that they are very, very dense.

3D simulations of black holes demonstrate their hungry ways, and could begin to explain the life of quasars.
Why we don’t have to worry about being sucked into the supermassive black hole at the centre of the Milky Way
Black holes may be notorious for sucking up anything that gets in their way, but we have nothing to worry about from the one in our galaxy’s heart. At least not for another four billion years.
What is a dormant black hole?
Technically Sagittarius A*, the supermassive black hole at the centre of the Milky Way, is dormant.

What is Hawking radiation?
It should, in theory, be emitted by the boundary surrounding a black hole, and it's one of Stephen Hawking's most famous ideas.
Why do we think black holes are in the centre of galaxies?
Sagittarius A* at the centre of the Milky Way is a strong source of radio wave emissions and is thought to be a supermassive black hole.
'Vampire’ star system once thought to be a black hole spotted 1,000 light-years from Earth
Rare binary system takes its gruesome name from the fact that one of the stars sucks gas and dust away from its companion.
