NGC 2392, Eskimo Nebula, is a wonderful little planetary nebula Gemini. Visually this nebula looks much like its nickname, even in a small telescope. Planetary nebulas are formed when a star sheds its outer shell as it nears the end of its life. The core collapses into a fiercely bright white dwarf whose intense radiation sets the gas aglow, often with a beautiful blue/green color. The structure of this nebula shows that it experienced several shedding events.
