Hubble Frontier Fields View of Abell 2744 (image) ESA/Hubble Information Centre Caption This image of Abell 2744 is the first to come from Hubble's Frontier Fields observing programme, which is using the magnifying power of enormous galaxy clusters to peer deep into the distant universe. Abell 2744, nicknamed Pandora's Cluster, is thought to have a very violent history, having formed from a cosmic pile-up of multiple galaxy clusters. Credit NASA, ESA, and J. Lotz, M. Mountain, A.
