Green stars have long been part of science fiction, appearing in comics and movies, including the recent movie Supergirl. But astronomers have now identified a real star with a rare green glow. Named WD J1330+6435, it is a white dwarf that acquired a ghostly chartreuse hue after ingesting rocky debris from planets that once orbited it, Reuters reported. The white dwarf lies in the Milky Way galaxy, about 280 light-years from Earth in the constellation Draco. A light-year is the distance light travels in a year, or about 5.9 trillion miles (9.5 trillion km).
