   Explanation: Inside the Cocoon Nebula is a newly developing cluster of
   stars. Cataloged as [5]IC 5146, the beautiful nebula is nearly 15
   light-years wide. Climbing high in [6]northern summer night skies, it's
   located some 4,000 light years away toward the constellation Cygnus the
   Swan. Like other star forming regions, it stands out in red, glowing,
   [7]hydrogen gas excited by young, hot stars, and [8]dust-reflected
   starlight at the edge of an otherwise invisible [9]molecular cloud. In
   fact, the bright star found near the center of this nebula is likely
   only a few hundred thousand years old, powering the nebular glow as it
   [10]clears out a cavity in the molecular cloud's star forming dust and
   gas. A 29 hour long integration with a small telescope from Ayr,
   Ontario, Canada resulted in this [11]exceptionally deep color view
   tracing tantalizing features within and surrounding the dusty
   [12]stellar nursery.
