A1689-zD1 was the most distant and therefore earliest observed galaxy discovered as of February 2008. In October 2010 the discovery of galaxy UDFy-38135539 at 13 billion light-years made A1689-zD1 the second most distant galaxy in the universe. Due to its distance 12.8 billion light-years and the according considerable redshift ~7.6 the galaxy’s faint light reaches us at infrared wavelengths.
