‘Zombie’ star won’t die, even after exploding
PASADENA, Calif. -- It's the star that won't die, even though it has exploded and appeared to go down in a blaze of glory multiple times. This superlong supernova may be the first of its kind. When they first observed supernova iPTF14hls in September 2014, astronomers at Las Cumbres Observatory in California thought it was perfectly normal.
