What happens when you find something in the wrong place at the wrong time? That's a question astronomers have been trying to answer after finding several exploding stars outside the cozy confines of galaxies, where most stars reside. These wayward supernovae also have puzzled astronomers because they exploded billions of years before their predicted detonations. Astronomers using archived observations from several telescopes, including the Hubble Space Telescope, Lick Observatory, W. M. Keck Observatory, and the Subaru Telescope, have developed a theory for where these doomed stars come from and how they arrived at their current homes.
