- The Eskimo Nebula (NGC 2392), also known as the Clown-faced Nebula, Lion Nebula, or Caldwell 39, is a bipolar double-shell planetary nebula (PN). 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.

Out on summer break, Alexander Schmorell and two friends decided to bike from Munich to Donauwörth, intending to catch a boat and float down the Danube to Austria. On paper, the 100-kilometer (60 mile) bike ride looked easy. The terrain was relatively flat, a biker’s paradise.
