The Hubble Ultra Deep Field in optical light
This photo was taken by the Advanced Camera for Surveys on the Hubble Space Telescope. The Ultra Deep Field observations represent a narrow, deep view of the cosmos. Peering into the Ultra Deep Field is like looking through an eight-foot-long soda straw. In ground-based photographs, the patch of sky in which the galaxies reside (just one-tenth the diameter of the full moon) is so empty that only a handful of stars (with four-pointed spikes in the image) within the Milky Way galaxy can be seen.
