Hubble Deep Field South – Multiple Windows on the Universe
Peering at a small patch of sky near the south celestial pole, NASA's Hubble Space Telescope used its full array of instruments to look nearly all the way across the universe. Called the Hubble Deep Field South (HDF-S), this new far-look complements the original Hubble "deep field" taken in late 1995, when Hubble was aimed at a small patch of space in the opposite direction on the sky, near the north celestial pole.

The field of view is 15 arc minutes, approximately half the angular diameter of the full moon. The respective fields of Hubble's three instruments are outlined.

Glaring fiercely across 12 billion light-years of space is the brilliant beacon of a distant quasar (z=2.2). Most of the galaxies in this view lie between us and the quasar. The image was taken with the camera on the Space Telescope Imaging Spectrograph (STIS). The STIS recorded how numerous invisible intervening clouds of hydrogen gas affected the quasar's light. Some of the galaxies in the image may be linked to these clouds.

The image has a striking similarity to the WFPC2's picture of the northern deep field. The full color picture can be used to estimate galaxy distance and ages.
