SH2-115 and SH2-116 (2023)
Sharpless 115 is a large, faint emission nebula in the constellation Cygnus approximately 1.5 degrees northwest of Deneb. It displays a chaotic morphology of gas emissions and dark nebulae. It is powered by the hot stars and is located about 7500 light years away and is just under 100 light years in diameter. Sharpless 116 (circular object) was considered a planetary nebula but more recent studies indicate it is a small patch of emission nebula.
