Before they become white dwarfs, they expand, engulf, and destroy any nearby planets. Astronomers have spotted a debris disk around a white dwarf, made from the dust of destroyed planets. Observations show that two new resurrected planets have formed in this disk, creating dead planets orbiting a dead star....
