The Butterfly Nebula, IC1318, is a mix of emission and dark nebulae near the bright star Sadr in constellation Cygnus and lies some 4900 light years away. By comparison, Sadr is a foreground star and lies 1900 light years away. The dark molecular clouds running through the region are physically related to the emission nebula and gives the nebula its distinct butterfly shape.
