Halo of the Cat's Eye

The Cat's Eye Nebula, NGC 6543, is one of the sky's best-known planetary nebulae. Its haunting symmetries are visible in the central region of this false-color picture, processed to reveal an enormous, faint halo of gaseous material. This halo, over three light-years across, surrounds the brighter, familiar planetary nebula. Made with data from the Nordic Optical Telescope, the composite picture shows emission from nitrogen atoms as red and oxygen atoms as blue-green.
