Description

Gamma Cygni Nebula or the  Sadr Region  (IC 1318)    7 20 2022 The Gamma Cygni Nebula, also known as the Sadr Region or IC 1318, is a diffuse emission nebula that can be seen around Sadr (Gamma Cygni), the star at the center of the Northern Cross, which marks the heart of Cygnus, the Swan. Despite the name, the star and the nebula are unrelated. The Gamma Cygni Nebula is considered an emission nebula because it is ionized by the radiation of the nearby stars and it emits visible light as a result. The visible portion of the H II region stretches over an area more than 100 light years across. The dark dust lane is responsible for the nebula’s distinctive shape, resembling that of a butterfly, which is why IC 1318 is sometimes also known as the Butterfly Nebula.
