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

File:NGC 6543 expansion.gif. This image shows the expansion over a period of three years of the planetary nebula NGC 6543, the Cat's Eye Nebula.All planetary nebulae are expanding, and will eventually disperse into the interstellar medium, enriching it with heavy elements such as carbon and oxygen.
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 ...
The Cat's Eye Nebula, or NGC 6543, is a planetary nebula in the Draco constellation. It has a relatively high apparent magnitude of +8.1, and the central star of the nebula is approximately 10,000 times the luminosity of our sun. NGC 6543 is located 3,600 light years from the Earth. It is expanding, and unexplainedly ejecting the concentric ...
