Ngc 6543 Is Located Almost At The North Pole Of Earth's Orbit And Is Therefore Also Known By The Older Name Of The Ecliptic North Pole Nebula.
The diameter of the cats eye nebula is about 1,000 light years across. Declination +66° 37′ 59.52″ constellation: 17 h 58 m 33.423 s:
The Cat's Eye Nebula Is Therefore Small Than Our Home Galaxy.
It is estimated to be 1,000 years old. Tt was discovered by william herschel in 1786. Cat's eye nebula (ngc 6543) is a planetary nebula.
The Cat's Eye Nebula (Ngc 6543) Is A Planetary Nebula In The Constellation Of Draco.
The cat's eye nebula (ngc 6543) is a young planetary nebula in the constellation draco, midway between delta and zeta dra; To put this in context, the milky way galaxy, that is the galaxy that we currently reside in is about 100,000 light years across. The image from hubble's advanced camera for surveys (acs) shows a bull's eye pattern of eleven or even more concentric rings, or shells, around the cat's eye.
The Full Beauty Of The Cat's Eye Nebula (Ngc 6543) Is Revealed In This New, Detailed View From Nasa's Hubble Space Telescope.
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. 17 h 58 m 33.4 s: Ngc 6543 ic 4677 right ascension:
Its Central Pnn Is A Hot Dying Star With A Temperature Of 80,000 Kelvin.
Declination +66° 37′ 59″ distance: Though the cat's eye nebula was one of the first planetary nebulae to be discovered, it is one of the most complex such nebulae seen in space. The nebula, formally cataloged ngc 6543, is every bit as inscrutable as the j.r.r.
