Explained: What are supermassive black holes, the one which was photographed at the centre of The Milky Way

Astronomers have captured the image of Sagittarius A*, the black hole at the centre of the Milky Way for the first time. Sagittarius A* is actually a supermassive black hole. We take a look at what exactly is a supermassive black hole.

Black holes do not move around sucking in objects like a vacuum cleaners, say scientist

He said if the Sun became a black hole, it wouldn't suck other planets; the Earth would still revolve around it, except there wouldn't light and the planet would be very cold.
