Abell 21, the Medusa Nebula in the constellation Gemini.

This is the faint but large planetary nebula known as the Medusa Nebula, but officially Abell 21 or PK 205+14.1 in Gemini. It was discovered in 1955 and was once classified as a supernova remnant. The very sparse open cluster NGC 2395 is at upper right from the nebula.. The nebula is thought to be 4 light-years across and 1500 light-years away.
