Officially being reported in tomorrow's [I know this post will be labelled as twelve-something, it's before midnight in this time zone] edition of Nature, the image of a "proto-galaxy" has been confirmed in the Hubble Ultra Deep Field taken a few months after the WFPC3 was installed.

The object was in existence less than 500 million years after the Big Bang and is composed of blue stars.

The team that made this discovery also noticed the rate of star formation increased as time from the Big Bang increased. From 480 million years after the Big Bang to 650 million years after, star birth increased tenfold. It then doubled from that by 780 million years after the Big Bang.

The Hubble Space Telescope needed 400 orbits around the Earth to gather from the constellation Fornax the light necessary to show objects in the Field down to 30th magnitude. The Advanced Camera for Surveys took two images per orbit--800 total.

An international group of astronomers has broken the distance record. The galaxy GN-z11 has been imaged as it appeared 13.4 billion years ago, just 400 million years after the Big Bang! GN-z11 is in the constellation Ursa Major, outside of the famous Big Dipper asterism.
