The Eskimo Nebula (NGC 2392)
The Eskimo Nebula (NGC 2392) is a bipolar double-shell planetary nebula about 6500 light-years away in the constellation of Gemini. It was discovered by astronomer William Herschel in 1787. The formation resembles a person's head surrounded by a parka hood. It is surrounded by gas that composed the outer layers of a Sun-like star. The visible inner filaments are ejected by a strong wind of particles from the central star. The outer disk contains unusual, light-year-long filaments.
