"UDFy-38135539 (also known as "HUDF.YD3") is the Hubble Ultra Deep Field (UDF) classification for a galaxy which (as of October 2010) has been calculated to have a light travel time of 13 billion years[1] with a present distance of around 30 billion light-years, thus making the galaxy the most distant object in the universe known to have existed and which has been observed from Earth."
Awesome.
