The Cat's
Eye. NGC
6543, or The Cat's Eye Nebula, is one of the most complex nebulae
in the category of "planetary nebula". Planetary nebula
are formed by the expulsion of a shell of gas by a star in the later
stages of its existence. This gas is lit by its interactions with
radiation from the star. The central star in NGC 6543 might actually
be a binary system and this nebula might be the result of two events.
