   Explanation: East of Antares, [5]dark markings sprawl through crowded
   star fields toward the center of our Milky Way Galaxy. [6]Cataloged in
   the early 20th century by astronomer [7]E. E. Barnard, the obscuring
   interstellar dust clouds [8]include B59, B72, B77 and B78, seen in
   against the starry background. Here, their combined shape suggests [9]a
   pipe stem and bowl, and so the dark nebula's popular name is the Pipe
   Nebula. The deep and expansive view covers a full 10 by 10 degree field
   in the [10]pronounceable constellation Ophiuchus. The Pipe Nebula is
   part of the Ophiuchus dark cloud complex located at a distance of about
   450 light-years. [11]Dense cores of gas and dust within the Pipe Nebula
   are collapsing to form stars.
