| The Hubble Deep Field South is the deepest view of the Universe ever obtained of a small portion of the Southern Hemisphere sky. The image was obtained over a period of ten consecutive days in September and October of 1998. The primary utility of the image is to detect and identify extremely distant galaxies. Because light travels at a fixed and finite speed, distant galaxies are seen as they were in the distant past, hence the Hubble Deep Field South image provides a look back in time toward the early history of the Universe. The most distant galaxies in the image are seen as they were when the Universe was less than 5% of its current age, or within about 750 million years of the Big Bang. |
