This image (taken in near-infrared light) was taken in the same region as the Ultra Deep Field in 2004. The total exposure time amounts to a little over forty-eight hours. The faintest objects in the field of view are about one-billionth the brightness that can be perceived with the human eye.

The James Webb Space Telescope, Hubble's planned successor (launch slated for 2014 or 2015), will look even farther into the past using infrared wavelengths.

Greg Bothun of the University of Oregon states there are at least 10,000 different objects in the HUDF. In 2007 Cornell graduate student Ryan Anderson extrapoled to estimate the number of stars in the visible Universe at 123 quintillion stars (100 million million million).

The Space Telescope Science Institute's Amazing Space section has a neat zoomable version of the image. It's not labelled--I don't know if the objects have been officially labelled or not.
