Astronomers have discovered a weird white dwarf star with a metallic scar on its surface — the last remnant of a hapless planet consumed by the killer star.
The white dwarf, called WD 0816-310, is a superdense husk of a dead star located 63 light-years from Earth. Astronomers previously assumed that the fragments of planets or asteroids shredded and consumed by white dwarfs are eventually spread evenly across their surfaces.
