      IC 1318

      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 centre of the Northern Cross, which marks the heart of Cygnus, the Swan. Despite the name, the star and the nebula are unrelated. Even though it looks embedded in the nebulosity, Sadr is approximately 1,800 light years distant, while the nebula is much further away, at 4,900 light years. The nebula glows as a result of nearby stars releasing streams of charged particles which ionise the gasses causing them to emit light. The area to the top right is known as the ‘Butterfly’ Nebula, a double-lobed cosmic cloud
