A warp in space time gave one supernova, or exploding star, more than one chance to shine.We've written about more common-place occurrences of this phenomenon (called gravitational lensing) before. When a galaxy or cluster of galaxies is massive enough, it can bend the light that passes through it. When these objects are lined up properly with Earth, a small object can end up getting magnified by the gravitational lens sitting "in front" of it.
