This space animation was commissioned by National Geographic magazine for an article entitled 'The Truth about Black Holes'. It shows a supermassive black hole at the centre of the Milky Way galaxy, shredding and consuming a passing cloud of gas, and is based an an actual event. Black holes cannot be seen by definition, because they emit no light. But they can be seen indirectly, as in this image, if they are surrounded by a ring of stellar debris, an accretion disc.
