Space colony. Artwork of a hypothetical colony of spacecraft orbiting close to a white dwarf star (upper right). A white dwarf star is the collapsed core of a star. The star's core collapsed due to cessation of its nuclear fusion. The outer layers were lost to form a planetary nebula (entire background). White dwarfs shine only by their remaining heat,and gradually cool and go out over trillions of years. The Sun will end up as a white dwarf star some 5 billion years from now. In this image,intelligent life forms migrated away from their dying planet to be nearer the white dwarf to ensure they could receive enough energy | |
