M27 is a planetary nebula that lies about 1200 light-years from Earth and has a diameter of about 2.4 light-years. It's expansion rate indicates that the red giant that spawned it erupted between 3000 and 4000 years ago. The white dwarf remanant of the red giant is the small blue star at the center of the nebula. This image shows some of the subtle detail inside the nebula.
