More than 12 billion years of cosmic history are shown in this panoramic view of thousands of galaxies in various stages of assembly. The view covers a portion of the southern field of a galaxy census called the Great Observatories Origins Deep Survey (GOODS).
Some Hubble images use data acquired over several days of observations.
