The Nebulous Realm of WR 134

Joint project by Rochus Hess and Bernd Wallner

WR134 - Wolf Rayet Star, surrounded by ring-shaped nebula structures.
This fascinating object is located in the constellation Cygnus, about 6,000 light-years away! The image is the result of a collaboration with my friend Bernd Wallner from Burghausen. WR 134 is a rare and extremely hot star in Cygnus, and the most striking feature is the spectacular ring-shaped nebulae. These emission nebulae, consisting of hydrogen (red) and oxygen (blue-green), are created by the intense stellar wind of the star.WR 134 has five times the radius of the Sun, but due to its high temperature, it shines 400,000 times brighter!
