Halo of the Cat's Eye

What created the unusual halo around the Cat's Eye Nebula? No one is sure. The Cat's Eye Nebula, NGC 6543, is one of the best-known planetary nebulae in the sky. While haunting symmetries are visible in the bright central region, this image features its intricately structured outer halo, which spans over three light-years. Planetary nebulae are the final phase in the life of a Sun-like star.
