What is the most complex planetary nebula ever seen?

This NASA Hubble Space 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.

What is the cat's eye?

The Cat’s Eye (NGC 6543) represents a brief, yet glorious, phase in the life of a sun-like star. This nebula’s central star may have produced the simple, outer pattern of dusty concentric shells by shrugging off outer layers in a series of regular convulsions. But the formation of the beautiful, more complex inner structures is not well understood.
