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 ...

The Cat's Eye Nebula is one of the most intricate and complex planetary nebulae known. This Hubble Space Telescope image reveals a mass of twists and knots of material in the nebula's inner region. The origin of this structure is not yet well understood by astronomers .

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
On the night of Oct. 5, 1923, Hubble pointed the 100-inch telescope toward M31, a blob of faint light then known as the Andromeda nebula. The human eye only collects up to 0.2 seconds of visual ...
