The Eskimo Nebula (NGC 2392), or Caldwell 39, is a bipolar double-shell planetary nebula, discovered 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.
NGC 2392 lies about 6500 light-years away in the constellation of Gemini. At the center of NGC 2392, there is an O-type star (designated HD 5908) with a spectral type of O(H)6f.
