Hubble's Cosmic Treasures

January 21, 2004
NASA's Hubble Space Telescope has snapped an unparalleled image of a wide swath of the sky, unveiling 10,000 galaxies, which could help astronomers understand how large galaxies like our Milky Way evolved. The new mosaic, taken by the orbiting observatory's Advanced Camera for Surveys, is the largest color photograph ever made by the telescope, covering an area of sky about the apparent size of the full moon. To construct the image, a team of astronomers stitched together 78 separate exposures showing the region around the constellation Fornax in the Southern Hemisphere. The astronomers compared constructing the mosaic to making a big picture of a mountain range by pasting together individual pictures of each mountain.
