Sh 2-106, also known as the Celestial Snow Angel, is an emission nebula and a star formation region in the constellation Cygnus. It is a H II region estimated to be around 2,000 light years (600 pc) from Earth, in an isolated area of the Milky Way.
In the center of the nebula is a young and massive star that emits jets of hot gas from its poles, forming the bipolar structure. Dust that surrounds the star is also ionized by it. The nebula spans about 2 light-years across.
