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: [7]The center of our Milky Way galaxy can be found some
   26,000 light-years away toward the constellation [8]Sagittarius. Even
   on a dark night, you can't really see it though. [9]Gaze in that
   direction, and your sight-line is quickly obscured by intervening
   interstellar dust. In fact, dark dust clouds, glowing nebulae, and
   crowded starfieds are packed along the fertile galactic plane and
   central regions of our galaxy. This annotated view, a mosaic of dark
   sky images, highlights [10]some favorites, particularly for small
   telescope or binocular equipped skygazers. The cropped version puts the
   direction to the galactic center on the far right. It identifies
   well-known Messier objects like the Lagoon nebula (M8), the Trifid
   (M20), [11]star cloud M24, and some of E.E. Barnard's [12]dark markings
   on the sky. A full version extends the view to the right toward the
   constellation Scorpius, in all covering over 20 degrees [13]across the
   center of the Milky Way.
