This illustration shows a glowing stream of material from a star, disrupted as it was being devoured by a supermassive black hole. When a star passes within a certain distance of a black hole -- close enough to be swallowed up -- the stellar material gets stretched and compressed as it is pulled in. A black hole’s destruction of a star, called ‘stellar tidal disruption,’ releases an enormous amount of energy, brightening the surroundings in an event called a flare.
