This Hubble telescope image shows one of the
most complex planetary nebulae ever seen, NGC 6543, nicknamed the "Cat's
Eye Nebula." Hubble reveals surprisingly intricate structures including
concentric gas shells, jets of high-speed gas, and unusual shock-induced
knots of gas. Estimated to be 1,000 years old, the nebula is a visual
"fossil record" of the dynamics and late evolution of a dying
star.
