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.

   [2]A starfield is shown with thin wisps of gray and red running through
    it. In the center is an usual ball -- which is a globular cluster of
      stars upon closer inspection. Please see the explanation for more
                            detailed information.

   Explanation: Stars, like bees, swarm around the center of bright
   globular cluster M15. The central ball of over 100,000 [4]stars is a
   relic from the [5]early years of [6]our Galaxy, and continues to orbit
   the [7]Milky Way's center. [8]M15, one of about 150 [9]globular
   clusters remaining, is noted for being easily visible with only
   [10]binoculars, having at its center one of the [11]densest
   concentrations of stars known, and containing a high abundance of
   [12]variable stars and [13]pulsars. The featured image of M15 was taken
   by combining [14]very long exposures -- 122 hours in all -- and so
   brings up [15]faint wisps of gas and dust in front of the giant ball of
   stars. [16]M15 lies about 35,000 [17]light years away toward the
   [18]constellation of the Winged Horse ([19]Pegasus).
