This image, released on 10/30/14, is of a massive galaxy cluster called Abell 2744, which is also nicknamed Pandora's Cluster. Astronomers, using the Hubble Space Telescope recently found forensic evidence of galaxies torn apart long ago in this area of space. The glow comes from stars scattered into intergalactic space as a result of a galaxy's disintegration. (NASA/ESA)
