   Explanation: A study in contrasts, this colorful skyscape features
   stars, dust, and glowing gas in the vicinity of NGC 6914. The
   interstellar complex of nebulae lies some 6,000 light-years away,
   toward the high-flying northern constellation Cygnus and the plane of
   our Milky Way Galaxy. Obscuring interstellar dust clouds appear in
   silhouette while reddish hydrogen emission nebulae, along with the
   dusty blue reflection nebulae, fill the cosmic canvas. Ultraviolet
   radiation from the massive, hot, young stars of the extensive Cygnus
   OB2 association ionize the region's atomic hydrogen gas, producing the
   characteristic red glow as protons and electrons recombine. Embedded
   Cygnus OB2 stars also provide the blue starlight strongly reflected by
   the dust clouds. The over 1 degree wide telescopic field of view spans
   about 100 light-years at the estimated distance of NGC 6914.
