On January 15, 1996, NASA released to the public one of the most extraordinary astronomical images of all time. The Hubble Deep Field (Fig. 7.1), a composite of 342 separate WFPC2 exposures taken from December 18–28, 1995, covered an area of the sky of only 2.5 arc-minutes, and is located in a nearly featureless area in Ursa Major (Fig. 7.2).
