Accretion disk around a white dwarf (centre),artwork. An asteroid (bottom right) is being pulled towards the white dwarf. The accretion disk is made up of debris from the star's former planetary system. The Hubble Space Telescope has found a similar system in the star cluster Hyades,150 light years from Earth. A pair of white dwarves,the burned out remnants of a star,are at the centre of the system and are being polluted by debris falling onto them | |
