Hubble Deep Field

The Hubble Deep Field is a rather uninteresting region 2.7 x 2.7 arcmin in size at high galactic latitude (low galactic extinction, no known interesting sources) that was observed for a total of 150 orbits by the Hubble Space Telescope Wide Field Planetary Camera. Images were taken in four filters centered roughly at 3000, 4000, 6000 and 8000 Angstroms.

The field is full of galaxies, most of which are at high redshifts. Here are a few conclusions derived from the observations of such distant galaxies.
