Hubble Deep Field

n.
An image taken by the Hubble Space Telescope of a small area of sky located in the constellation Ursa Major and chosen because it contains few obstacles that interfere with deep-space imaging. The long exposure time used enabled imaging of distant galaxies as they appeared very early in the history of the universe.
