The light of the galaxy (IMAGE) University of Copenhagen - Faculty of Science Caption The light of a galaxy with an exploding star takes different paths around an intermediate galaxy cluster before it reaches us. Astronomers from the Cosmic Dawn Center, among others, have calculated that one route is about 21 light years longer than the other. As such, they predict that come 2037, we should be able to spot the supernova yet again. Click here for an animated version (illustration: Peter Laursen, Cosmic Dawn Center).
