Images of the Supernova (IMAGE) University of Copenhagen - Niels Bohr Institute Caption In the large square to the right in the image you see the four light representations of the supernova that was spotted on Nov. 11, 2014. The blue circle shows another location in the galaxy cluster where you probably would have been able to see a single image of the supernova 20 years ago and the red circle shows where the supernova will appear again in a few years, according to calculations. This will give the astronomers a rare opportunity to get backward glance at the supernova and will also enable the researchers to improve their calculations of the amount and distribution of dark matter -- both in the galaxy cluster and in the one elliptical galaxy.
