UDFj-39546284
UDFj - 39546284 is a candidate for a galaxy with a redshift of z ~ 10 It is thus, at the time of its discovery in January 2011, which is probably most distant known object in the universe. The galaxy has been discovered in the Hubble Ultra Deep Field in the infrared range.
Properties
At a redshift of z = 10, the required light 13.2 billion years of UDFj - 39,546,284 to the earth, the universe was thus during the transmission of light 480 million years young. This is UDFj - 39546284 one of the first galaxies in the Universe. Earlier searches found many galaxies that have formed about 650 million years after the Big Bang. If confirmed, the discovery UDFj - 39546284 is the only known galaxy, which is even older. At this time, the number of galaxies and stars must have grown rapidly.
