This image of galaxy cluster MACS 1206 is part of the broad survey with NASA's Hubble Space Telescope. The apparently distorted shapes in the galaxy cluster are distant galaxies from which the light is bent by the gravitational pull of dark matter, an invisible material within the cluster of galaxies. MACS J1206 has been observed as part of the new CLASH survey of galaxy clusters.
