Maybe déjà vu is real... Or maybe it's just deflections off of gravitational lenses. This is the first time a supernova explosion has been split into multiple images across intervening masses. The picture above is inside a galaxy cluster, taken in November by the Hubble Space Telescope. The multiplied Supernova, Refsdal, occurred in the universe far behind the cluster. Measuring the locations and time delays between images may allows astrophysicists to understand the amount of dark matter in not just the galaxy, but the cluster too. There is hope that a fifth image presents itself in the near future.
