      Explanation: Ridges of glowing interstellar gas and dark dust clouds   
      inhabit the turbulent, cosmic depths of the Lagoon Nebula. Also known   
      as M8, the bright star forming region is about 5,000 light-years   
      distant. But it still makes for a popular stop on telescopic tours of   
      the constellation Sagittarius, toward the center of our Milky Way   
      Galaxy. Dominated by the telltale red emission of ionized hydrogen   
      atoms recombining with stripped electrons, this stunning, deep view of   
      the Lagoon is nearly 100 light-years across. Right of center, the   
      bright, compact, hourglass shape is gas ionized and sculpted by   
      energetic radiation and extreme stellar winds from a massive young   
      star. In fact, although digitally removed from the featured image, the   
      many bright stars of open cluster NGC 6530 drift within the nebula,   
      just formed in the Lagoon several million years ago.
