The Cat's Eye Nebula (also known as NGC 6543 and Caldwell 6) is a planetary nebula in the northern constellation of Draco, discovered by William Herschel on February 15, 1786. It was the first planetary nebula whose spectrum was investigated by the English amateur astronomer William Huggins , demonstrating that planetary nebulae were gaseous ...
Cat's Eye Nebula (NGC 6543) Cat's Eye Nebula (NGC 6543) Nebulium was a proposed element found in astronomical observation of a nebula by William Huggins in 1864. The strong green emission lines of the Cat's Eye Nebula, discovered using spectroscopy, led to the postulation that an as yet unknown element was responsible for this emission.

One model is breaking barriers in the fashion world. 29-year-old Caitin Stickels, from Seattle, was born with Schmid-Fraccaro, also known as "Cat Eye Syndrome".
File:NGC 6543 outer halo.jpg. The Cat's Eye Nebula is a planetary nebula, formed when a star like the sun ejected its outer layers at the end of its life.Long exposure images reveal several distinct episodes of mass loss from the star, with the inner bright nebula surrounded by smooth concentric rings, in turn surrounded by a giant shell of clumpy gas
