The Wizard Nebula

This open cluster (NGC 7380) was discovered by Caroline Herschel in 1787. It is located in the constellation of Cepheus. The surrounding emission nebula was included in William Herschel's catalogue as he was aware of his sisters discovery. The nebula's shape is sculpted by stellar winds from this open cluster. Ultraviolet light from type O and B stars formed within the molecular cloud ionized the gas around them causing the nebula to glow. This nebula will dissipate within the next few million years but some stars in it will likely outlive our Sun.
