      Explanation: These brightly outlined flowing shapes look ghostly on a   
      cosmic scale. A telescopic view toward the constellation Cassiopeia,   
      the colorful skyscape features the swept-back, comet-shaped clouds IC   
      59 (left) and IC 63. About 600 light-years distant, the clouds aren't   
      actually ghosts. They are slowly disappearing though, under the   
      influence of energetic radiation from hot, luminous star gamma Cas.   
      Gamma Cas is physically located only 3 to 4 light-years from the   
      nebulae and lies just above the right edge of the frame. Slightly   
      closer to gamma Cas, IC 63 is dominated by red H-alpha light emitted as   
      hydrogen atoms ionized by the hot star's ultraviolet radiation   
      recombine with electrons. Farther from the star, IC 59 shows less   
      H-alpha emission but more of the characteristic blue tint of dust   
      reflected star light. The field of view spans over 1 degree or 10   
      light-years at the estimated distance of the interstellar apparitions.
