Cat's eye nebula facts. Its angular expansion rate is. See the NASA press release for more info. First discovered by William Herschel on February 15th 1786 this planetary nebula is a real gem of the night sky.

Billions of years ago there was a normal Sun like star located far away from the Earth. One problem that scientist face with planetary nebula is determining their distance from earth. Cats Eye Nebula Facts and Info.

The Cats Eye Nebula NGC 6543 is a planetary nebula in the constellation of Draco. A light year is about 6 trillion miles how far light moves in a year. The image title is in reference to the Cats Eye Nebula a well studied iconic nebula that shares similar features to this image of Eminescu such as notably the blues yellows and spherical shape of the formation.

The Cats Eye is one of the most structurally complex nebulae known. The Cats Eye Nebula consists mainly of hydrogen and helium with smaller quantities of heavier elements. A planetary nebula forms when Sun-like stars gently eject their outer gaseous layers that form bright.

The Cats Eye nebula has a Wolf-Rayet Star at the centre which is 10000 brighter than our own star the Sun. The Cats Eye Nebula is a planetary nebula that is located 3262 Light Years away from the Earth in the constellation of Draco the Dragon. The HST images seem to indicate that the central star is actually a binary system and that the nebula we see today is actually the result of at least two separate events.

The Cats Eye Nebula was the first planetary nebula to be discovered with a spectroscope. It was used to develop Expansion parallax. The Cats Eye Nebula is a very bright nebula in the northern constellation Draco.
