Cat's Eye Nebula Age

I took this over two nights from Nerpio.

Cat's eye nebula age. It has been expanding ever since as can be seen by comparing Hubble images taken in 1994 1997 2000 and 2002. In 1994 Hubble first revealed NGC 6543s surprisingly. The image from Hubbles Advanced Camera for Surveys ACS shows a bulls eye pattern of eleven or even more concentric rings or shells around the Cats Eye.

Known as NGC 6543 it is located 3300 light years from Earth in the constellation Draco. The distance measured by the Gaia mission is 655 light-years. No two look alike.

Heres my image of the Cats Eye Nebula NGC 6543 in Bi-Colour HαOiii. The Cat Eye Nebula NGC 6543 is a mythical object from the deep sky of the Northern Hemisphere. A planetary nebula is the glowing gas ejected during the final stages of evolution of a star similar in mass to our Sun.

The Cat Eye Nebula NGC 6543 is a mythical object from the deep sky of the Northern Hemisphere. Each ring is actually the edge of a. The Cats Eye Nebula was discovered by Herschel in the late 18th century.

Structurally it is one of the most complex of the known nebulae. The Discovery the Cats Eye Nebula. The different age material then interacts to form the various shock waves knots you can see.

It is similar in appearance to the Cats Eye Nebula and the Ring Nebula whose size age and physical characteristics are similar to the Dumbbell Nebula varying only in its relative proximity and the. The nebulas structural complexity may be the result of material being expelled from a binary central star but the existence of a binary companion has not yet been. The other nebulosity much fainter was apparently ejected from the star previously every 1500 years or so.
