About this image

This is a montage of some of the earliest galaxies found in the Hubble Ultra Deep Field. Their distances (expressed in red shift value) have been measured by the spectrograph on the Advanced Camera for Surveys. They show a variety of structure, some indicating galaxy mergers, which is one of the mechanisms for galaxies to grow.
