M83 Star Streams
Explanation: Big, bright, and beautiful,
spiral galaxy M83 lies a mere twelve million light-years away, near the southeastern tip of the very long
constellation Hydra. This
deep view of the gorgeous island universe includes observations from Hubble, along with ground based data from the European Southern Observatory's very large telescope units, National Astronomical Observatory of Japan's Subaru telescope, and
Australian Astronomical Observatory photographic data by D. Malin. About 40,000 light-years across, M83 is popularly known as the Southern Pinwheel for its pronounced spiral arms. But the wealth of
reddish star forming regions found near the edges of the arms' thick dust lanes, also suggest another popular moniker for M83, the
Thousand-Ruby Galaxy. Arcing near the top of the novel cosmic portrait lies M83's northern
stellar tidal stream, debris from the gravitational disruption of a smaller, merging satellite galaxy. The faint, elusive star stream was
found in the mid 1990s by enhancing photographic plates.
