The Cosmic Horseshoe is a spectacular gravitational lens, in an almost perfect Einstein Ring. The enormous gravity of a foreground galaxy cluster is magnifying the light from a more distant galaxy into a circle around it. And now, astronomers have worked out that the galaxy cluster contains a supermassive black hole with 36 billion times the mass of the Sun, one of the most massive ever measured in the Universe.
