The galaxy, known as UDFy-38135539, is one of several super-distant objects picked out from the Hubble Ultra Deep Field, the most sensitive snapshot ever taken of deep space. In time, astronomers may well spot objects that are even farther away, but this particular galaxy was the first of its type to go through the arduous process of having its measurements checked.
WAIT A MINUTE……..AN IMPORTANT UPDATE

The newfound galaxy candidate, discussed in this week’s issue of the journal Nature, is known by the unwieldy name UDFj-39546284. (Let’s call it UDFj for short.) Like the earlier candidate for the farthest galaxy, UDFy-38135539, it was detected amid other faint galaxies in a snapshot of the sky known as the Hubble Ultra Deep Field.
This particular candidate was singled out during an exhaustive search of the deep-field data in infrared wavelengths, which was gathered during 87 hours of observations by Hubble’s Wide Field Camera 3 in 2009 and 2010. Based on the characteristic shift in UDFj’s light spectrum, astronomers determined that the galaxy dated back to a time just 480 million years after the big bang.
I wouldn’t be a bit surprised to learn there’s one out there that’s even further away. But galaxies are very large. Since these guys are newly discovered, I’d say it would be asking a lot to expect “how well do we understand said galaxy”……
