Origin of the Hubble Deep Field
With the Hubble Space Telescope, scientists have been able to explore the outer reaches of the universe. In December 1995, a tiny section of the sky near the Big Dipper was selected for a prolonged observation using cameras located on the telescope.
For 100 hours over a 10-day period, the telescope was pointed at this part of the sky. Gazing at one spot for such a long time enabled Hubble to collect light from the farthest reaches of the universe.
The image that resulted is called the Hubble Deep Field (HDF).
