The Cat's Eye Nebula in Optical and X-ray

The Cat's Eye Nebula is a planetary nebula, the expelled gas from a dying star like our Sun. It is one of the brightest and most detailed planetary nebulae known. The central star, a white dwarf, may have created the outer shells by shedding layers in a series of convulsions. This image combines optical data from Hubble and X-ray data from Chandra.
