In 1994 Hubble first revealed NGC 6543s surprisingly. The central star will continue to expand for another 10000 years give or take just a tiny fraction of its total lifespan until the central star runs out of atmosphere. When a Sun-like star nears the.

A classic planetary nebula the Cats Eye NGC 6543 represents a final brief yet glorious phase in the life of a sun-like star.

It was the first planetary nebula to have its spectrum measured which demonstrated that it was largely composed of hot gases.

Heres my image of the Cats Eye Nebula NGC 6543 in Bi-Colour HαOiii. No two look alike. Huggins observations were the first indication that planetary nebulae consist of extremely rarefiedgases.

The Cats Eye Nebula has a complex intricate structure which includes knots bubbles concentric gas shells and jets of gas as seen in hi-res images taken by the Hubble Space Telescope in 1994. High-resolution images from the Hubble Space Telescope revealed extraordinary structures such as nodes jets and arch-like features. Herschel was a German-born astronomer who emigrated to Great Britain at age 19.

The nebula was discovered by William Herschelon February 15 1786 and was the first planetary nebula to be observed with a spectroscope by William Hugginsin 1864. There he built himself a telescope and started to study astronomy. Its haunting symmetries are seen in the very central region of this stunning false-color picture processed to reveal the enormous but extremely faint halo of gaseous material over three light-years across which surrounds the brighter familiar planetary nebula.
