The final stop in our journey through the constellation of Cygnus the Swan takes us to the Sadr Region. The Sadr Region is a diffuse emission nebula surrounding the super giant star Sadr which is located at the center of the Cygnus Cross (also referred to as the Northern Cross). This nebulous region includes popular targets such as the Butterfly Nebula (IC 1318), included in this image, and the Crescent Nebula (NGC 6888 already explored in this series). It contains webs of dark nebulae to compliment the diffuse emissions. As a trivia, Sadr is about 150 times the radius of the Sun and has a mass of 12 times that of the sun. That’s big!!! Stay tuned for the next part of the journey and remember to look up and experience an amazing Universe!
