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 very colorful sky field is shown featuring many stars and nebulas
    that appear red, yellow, blue, and brown. Please see the explanation
                       for more detailed information.

   Explanation: Behold one of the most photogenic regions of the night
   sky, captured impressively. [4]Featured, the band of our [5]Milky Way
   Galaxy runs diagonally along the bottom-left corner, while the colorful
   [6]Rho Ophiuchi cloud complex is visible just right of center and the
   large red circular [7]Zeta Ophiuchi Nebula appears near the top. In
   general, red emanates from [8]nebulas glowing in the light of
   [9]excited hydrogen gas, while blue marks interstellar dust
   preferentially [10]reflecting the light of bright young stars.
   [11]Thick dust usually appears [12]dark brown. Many iconic objects of
   the night sky [13]appear, including (can you find them?) the bright
   star [14]Antares, the [15]globular star cluster [16]M4, and the
   [17]Blue Horsehead nebula. [18]This wide field composite, taken over 17
   hours, was captured from [19]South Africa last June.
