The NGC 6914 Complex Image Credit & [3]Copyright: [4]Giorgio Ferrari Explanation: A study in contrasts, [5]this colorful skyscape features [6]stars, dust, and glowing gas in the vicinity of NGC 6914. The [7]interstellar complex of nebulae lies some 6,000 light-years away, toward the high-flying northern constellation [8]Cygnus and the plane of our Milky Way Galaxy. Obscuring interstellar dust clouds appear in silhouette while reddish hydrogen [9]emission nebulae, along with the dusty blue [10]reflection nebulae, fill the cosmic canvas. Ultraviolet radiation from the massive, hot, young stars of the extensive [11]Cygnus OB2 association ionize the region's atomic [12]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.
