Light from the most distant observable objects in the universe is red-shifted to such an extent that ultraviolet light is shifted deep into the infrared. A search for objects with infrared emission consistent with very early galaxies, which examined more than 700,000 candidate sources, has identified a galaxy given the imaginative name HD1, which has a redshift of 13.27, indicating we are seeing it as it was around 300 million years after the Big Bang. This makes it the most distant galaxy ever observed and raises the possibility that its intense ultraviolet emission is due to the presence of Population III stars, never before observed, which theorists believe were super-massive, short-lived stars that were the first to form in the early universe.
Here is a press release from the Harvard-Smithsonian Center for Astrophysics, “Scientists Have Spotted the Farthest Galaxy Ever”, describing the discovery.
