Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

   Explanation: Big, bright, and beautiful, [5]spiral galaxy M83 lies a
   mere twelve million light-years away, near the southeastern tip of the
   very long [6]constellation Hydra. About 40,000 light-years across, M83
   is known as the Southern Pinwheel for its pronounced spiral arms. But
   the wealth of [7]reddish star forming regions found near the edges of
   the arms' thick dust lanes, also suggest another popular moniker for
   M83, the [8]Thousand-Ruby Galaxy. This new deep telescopic [9]digital
   image also records the bright galaxy's faint, extended halo. Arcing
   toward the bottom of the cosmic frame lies a [10]stellar tidal stream,
   debris drawn from massive M83 by the gravitational disruption of a
   smaller, merging satellite galaxy. Astronomers David Malin and Brian
   Hadley [11]found the elusive star stream in the mid 1990s by enhancing
   photographic plates.
