(DESCRIPTION) 
 A nebula with several gaseous spheres. 


Text, CAT'S EYE NEBULA. The Cat's Eye Nebula is one of the most complex planetary nebulae ever seen. 


Hubble Space Telescope images reveal multiple shells of gas and dust that were probably ejected by the star early in the nebula's formation. 


Later, the dying star ejected symmetric lobes of gas in opposite directions. 


A pair of wobbling jets might have pushed away some of the gas into two swirling tendrils on either end.
