      Explanation: Difficult to capture, this mysterious, squid-shaped   
      interstellar cloud spans nearly three full moons in planet Earth's sky.   
      Discovered in 2011 by French astro-imager Nicolas Outters, the Squid   
      Nebula's bipolar shape is distinguished here by the telltale blue   
      emission from doubly ionized oxygen atoms. Though apparently surrounded   
      by the reddish hydrogen emission region Sh2-129, the true distance and   
      nature of the Squid Nebula have been difficult to determine. Still, one   
      investigation suggests Ou4 really does lie within Sh2-129 some 2,300   
      light-years away. Consistent with that scenario, the cosmic squid would   
      represent a spectacular outflow of material driven by a triple system   
      of hot, massive stars, cataloged as HR8119, seen near the center of the   
      nebula. If so, this truly giant squid nebula would physically be over   
      50 light-years across.
