(catalogue entry: Sharpless 2-106 | Sh2-106)
“The Celestial Snow Angel (catalogued as Sharpless 2-106 or Sh2-106), 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 ly (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 surrounding the star is also ionized by the star. The nebula spans about 2 light-years across.”
