      Explanation: NGC 6888, also known as the Crescent Nebula, is a about 25   
      light-years across, a cosmic bubble blown by winds from its central,   
      massive star. This deep telescopic image includes narrowband image   
      data, to isolate light from hydrogen and oxygen atoms. The oxygen atoms   
      produce the blue-green hue that seems to enshroud the nebula's detailed   
      folds and filaments. Visible within the nebula, NGC 6888's central star   
      is classified as a Wolf-Rayet star (WR 136). The star is shedding its   
      outer envelope in a strong stellar wind, ejecting the equivalent of the   
      Sun's mass every 10,000 years. In fact, the Crescent Nebula's complex   
      structures are likely the result of this strong wind interacting with   
      material ejected in an earlier phase. Burning fuel at a prodigious rate   
      and near the end of its stellar life, this star should ultimately go   
      out with a bang in a spectacular supernova explosion. Found in the   
      nebula rich constellation Cygnus, NGC 6888 is about 5,000 light-years   
      away.
