The Hubble Ultra Deep Field was the result of a million seconds of exposure time on the Hubble Space Telescope. It combined data from the Advanced Camera for Surveys and Near Infrared Camera and Multi-Object Spectrometer, and revealed over 10,000 galaxies in a patch of sky about 3 arcminutes in diameter, some of which are among the most distant objects known.
