Supernova Stellar hypoxia may help make more massive black holes Lower oxygen in a star may explain two cosmic mysteries at once. By Phil Plait 1 day ago Otherworldly blue lights in space are no longer shrouded in mystery There are things weirder than aliens out there. By Elizabeth Rayne 3 weeks ago For the first time, three supernovae are seen at the same time in a single galaxy! The spiral galaxy NGC 5605 is popping off exploding stars. By Phil Plait 1 month ago White dwarfs eat other white dwarfs and then wear their undigested bits Two newly discovered weird stars ate their companions. By Phil Plait 2 months ago How did the COW supernova get so bright so fast? A little pre-explosion gas. A superluminous supernova lit up previously ejected material. By Phil Plait 3 months ago Peeling back the layers on Eta Carinae, the galaxy's most terrifying star Eta Car is a monster, surrounded by the debris of violent eruptions. By Phil Plait 3 months ago A thousand-light-year-wide bubble around the Sun was blown by the ghosts of long-dead stars Local Bubble carved by supernova beginning 14 million years ago. By Phil Plait 4 months ago Monstrous red giant caught moments before going supernova Some stars may go gently into that good night, but some...don’t.
