| Description |
This is a Hubble Space Telescope image of the farthest spectroscopically confirmed galaxy observed to date (inset). It was identified as a very bright source in this Hubble image of a field of galaxies in the CANDELS survey (Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey). NASA's Spitzer Space Telescope also observed the unique galaxy. The W. M. Keck Observatory was used to obtain a spectroscopic redshift (z=7.7), extending the previous redshift record. Measurements of the stretching of light, or redshift, give the most reliable distances to other galaxies. This source is thus currently the most distant confirmed galaxy known, and it appears to also be one of the most massive sources at that time. The galaxy existed over 13 billion years ago. The near-infrared image of the galaxy (inset) has been colored blue as suggestive of its young stellar population. The CANDELS field is a combination of visible-light and near-infrared exposures.
