Within the Hubble Ultra Deep Field there are approximately 10,000 discrete objects. ... Most of these objects are very small and likely have masses in the range of 10 5 to 10 7 solar masses. Note the mass of the Milky Way galaxy is 10 12 solar masses. ... Finally, for you cosmologists/experts out there this ultra deep field is quite consistent with what was seen in the original Hubble Deep Field 5) don't necessarily have small angular diameters. ...

An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . THE HUBBLE DEEP FIELD . In December 1995, the Hubble Space Telescope, high above the Earth, focused on a tiny spot of dark sky for over 150 consecutive orbits. ... Here we see about a fourth of that "deep field" and it shows galaxies (and only galaxies) at many different distances. The farthest among these galaxies is estimated to be so far away, its light has taken over 10 billion years to reach us. ...
