image: In this Hubble Space Telescope image, the many red galaxies are members of the massive MACS J1149.6+2223 cluster, which creates distorted and highly magnified images of the galaxies behind it. A large cluster galaxy (center of the box) has split the light from an exploding supernova in a magnified background galaxy into four yellow images (arrows) to form an Einstein Cross. This material relates to a paper that appeared in the March 6, 2015, issue of Science, published by AAAS. The paper, by P.L. Kelly at University of California, Berkeley in Berkeley, CA, and colleagues was titled, 'Multiple images of a highly magnified supernova formed by an early-type cluster galaxy lens.' view more
