This complex and beautiful "planetary nebulae" is believed to be a glimpse of two dying stars rapidly expelling clouds of gas, 3000 light years away in the constellation Draco. The object, classified as NGC 6543, was photographed by the Hubble telescope in 1994 and nicknamed the "Cat's Eye Nebula." Scientists believe that a pair of moving, wobbling high-speed jets of gas are responsible for producing the bright arcs at the periphery. Photo used with permission from NASA.
