26 Cosmic Photos from the Hubble Space Telescope's Ultra Deep Field

NASA's Hubble Space Telescope holds the world record for peering farther into deep space than any other telescope of its time. It has imaged some of the most distant galaxies ever observed, allowing the telescope to look back in time to when the universe was in its infancy. This image, called the Hubble Ultra Deep Field, offers a core sample of the deep universe with diverse galaxies of various ages, sizes, shapes and colors.
