Pandora's Cluster
Wallpaper Description:
This space image of Abell 2744 is the first to come from Hubble's Frontier Fields observing programme. 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.Koekemoer, and the HFF Team (STScI).
