Astronomers discover a star that would not die
Supernovae, the explosions of stars, have been observed in the thousands and in all cases they marked the death of a star. Astronomers at Las Cumbres Observatory have discovered a remarkable exception — a star that exploded multiple times over a period of more than fifty years. Their observations are challenging existing theories on these cosmic catastrophes.
Astronomers discover ‘heavy metal’ supernova rocking out
Many rock stars don’t like to play by the rules, and a cosmic one is no exception. A team of astronomers has discovered that an extraordinarily bright supernova occurred in a surprising location. This “heavy metal” supernova discovery challenges current ideas of how and where such super-charged supernovas occur.
