Extended Groth Strip
Extended Groth Strip is an image of a small region in the constellation Ursa Major, based on the results of a series of observations by the Hubble Space Telescope. It covers an area 70 arcseconds across and 10 arcseconds wide. The image was assembled from over 500 separate exposures taken with the Space Telescope's Advanced Camera Survey at 63 different pointings, spread out over the course of one year from June 2004 to March 2005.
