Artist's impression of a binary star system consisting of a black hole (centre) and a red giant star (upper left). At lower right are the blue,wispy strands of a nebula,containing several hot young blue stars. A stream of gas is being pulled from the atmosphere of the red 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 spot at centre). For this reason,this type of system is known as an X-ray binary. Two jets of material are seen streaming outwards from the poles of the black hole | |
