Artist's impression of a binary star system consisting of a black hole (foreground) and a blue giant star (background). A stream of gas is being pulled from the atmosphere of the blue giant by the immense gravitational field of its companion. As the gas spirals down into the black hole it forms a flat accretion disc which heats up and emits X-rays (bright white region at centre). For this reason,this type of system is known as an X- ray binary | |
