December 13, 2012

THE DEEP END: Images of a small patch of sky called the Hubble Ultra Deep Field have revealed several of the most distant galaxies ever seen. The newfound galaxies and their associated redshifts are labeled on the Hubble image. 

Read articles from around the world about the discovery of the earliest galaxies, the deepest archeological dig of the Universe so far. It identified a record redshift of 11.9 for a previously known galaxy and provides the first comprehensive census of baby galaxies when the universe was only 400-400 million years old.  Brant Robertson, a PhD alumni of Harvard Astronomy department is a member of the discovery team. He was quoted in the following report.
