A Deep Field In The Southern Sky

Explanation: This deep view of the cosmos is the sequel to the 1995 hit Hubble Space Telescope Deep Field . Billed as the Hubble Deep Field South , it was produced by pointing the space telescope toward a patch of sky in the southern constellation Tucana . Over a period of 10 days, many separate exposures were accumulated and combined to reveal progressively fainter galaxies. The original deep field was constructed by observing a piece of sky in the northern constellation Ursa Major . Both stare down 12 billion light-year long tunnels to far-off and still mysterious times when young galaxies inhabited an infant universe . Hubble Deep Field South observations were released to an enthusiastic audience on November 23, 1998.
