Image Description and Details: NGC 6543, also known as the Cat's Eye Nebula, is a planetary nebula located in the constellation of Draco (located approximately 3,500 light-years away from Earth), discovered in 1786 by William Herschel, and its name comes from its characteristic ring with a bright, central region that resembles a cat's eye.
The brightness of the outer ring is due to the emission of light from the gas excited by the hot central star.
The inner disk is elliptical and elongated and the star at the center of the nebula is a remnant of an explosion from a star similar to the Sun.
