Description

IC 1318, otherwise known as the "Butterfly Nebula" is the area of hydrogen emission surrounding the star Sadr, the central star in the constellation of Cygnus. This images was captured in the light of hydrogen alpha...the specific wavelength of light given off by glowing hydrogen gas The dark areas are not simply void of stars...they are relatively dense clouds of dust that block the light of the stars beyond.
