Views from Space and Time

On September 25 the image " eXtreme Deep Field", or XDF, was assembled from 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. The XDF shows about 5,500 galaxies "The faintest galaxies are one ten-billionth the brightness of what the human eye can see." For more information visit the Hubble Site.
