Cat's Eye Nebula Diameter
600 x 590 Photo description.
Cat's eye nebula diameter. Though the Cats Eye Nebula was one of the first planetary nebulae to be discovered it is one of the most complex such nebulae seen in space. This image reveals new details of the Cats Eye Nebula catalogued as NGC 6543 one of the most complex planetary nebulae ever seen. The Cats Eye Nebula NGC 6543 is one of the best known planetary nebulae in the sky While there are many images of this object this rendition has captured the extremes of this difficult target.
What is an example of a planetary nebula. It would take a space ship 50000 years travelling at the speed of light to get from one side to the other. Cats Eye Nebula has a radius of 25000 light years or to put it another way it has a diameter of 50000 light years.
The star in the white dwarf stage is clearly visible in the center of the nebula the central part of which has a diameter of only 20 arc seconds which is tiny one of the reasons why it is relatively little imagined. The Cats Eye Nebula is 3x10 to the power of 16 meters in diameter. The nebula formally cataloged NGC 6543 is every bit as inscrutable as the JRR.
Seeing varys between 3-22 FWHM. Planetary nebulae are like snowflakes. This composite image with Hubble Space Telescope data red and green shows where the hot X-ray emitting gas appears in relation to the cooler material seen in optical wavelengths.
No two look alike. A stunning photo taken by the Hubble Space Telescope of the Cats Eye Nebula. The central star is expected to collapse into a white dwarf in a few million years.
The Cat Eye Nebula NGC 6543 is a mythical object from the deep sky of the Northern Hemisphere. The Cats Eye Nebula. Its central PNN is a hot dying star with a temperature of 80000 kelvin.
