                        Astronomy Picture of the Day

    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.

     An unusual looking galaxy is shown with a light bar running nearly
    vertical and blue stars and red nebulas around the edges. Please see
               the explanation for more detailed information.

   Explanation: It is the largest satellite galaxy of our home Milky Way
   Galaxy. If you live in the south, the Large Magellanic Cloud (LMC) is
   quite noticeable, spanning about 10 degrees across the night sky, which
   is 20 times larger than the full moon towards the southern
   constellation of the dolphinfish (Dorado). Being only about 160,000
   light years away, many details of the LMC's structure can be seen, such
   as its central bar and its single spiral arm. The LMC harbors numerous
   stellar nurseries where new stars are being born, which appear in pink
   in the featured image. It is home to the Tarantula Nebula, the
   currently most active star forming region in the entire Local Group, a
   small collection of nearby galaxies dominated by the massive Andromeda
   and Milky Way galaxies. Studies of the LMC and the Small Magellanic
   Cloud (SMC) by Henrietta Swan Leavitt led to the discovery of the
   period-luminosity relationship of Cepheid variable stars that are used
   to measure distances across the nearby universe.
