The farthest confirmed galaxy observed to date. It was identified in this Hubble image of a field of galaxies in the CANDELS survey (Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey). The W. M. Keck Observatory obtained a spectroscopic redshift (z=7.7), extending the previous redshift record. This is the most distant confirmed galaxy known, and it appears to also be one of the most massive sources at that time. The inset image of the galaxy is blue, suggesting very young stars.
