The Cat's Eye Nebula (also known as NGC 6543 and Caldwell 6) is a planetary nebula in the northern constellation of Draco, discovered by William Herschel on February 15, 1786. It was the first planetary nebula whose spectrum was investigated by the English amateur astronomer William Huggins, demonstrating that planetary nebulae were gaseous and ...
Helix Nebula. The Helix Nebula (also known as NGC 7293 or Caldwell 63) is a planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, most likely before 1824, this object is one of the closest of all the bright planetary nebulae to Earth. [ 3] The distance, measured by the Gaia mission, is 655±13 light ...

NGC 3242 (also known as the Ghost of Jupiter, Eye Nebula or Caldwell 59) is a planetary nebula located in the constellation Hydra . William Herschel discovered the nebula on February 7, 1785, and catalogued it as H IV.27. John Herschel observed it from the Cape of Good Hope, South Africa, in the 1830s, and numbered it as h 3248, and included it ...
Ring Nebula. M 57, [ 1] NGC 6720, [ 1] GC 4447. The Ring Nebula (also catalogued as Messier 57, M57 and NGC 6720) is a planetary nebula in the northern constellation of Lyra. [ 4] [. C] Such a nebula is formed when a star, during the last stages of its evolution before becoming a white dwarf, expels a vast luminous envelope of ionized gas into ...
Eskimo Nebula. NGC 2392, the Eskimo Nebula by HST in 1999. The Eskimo Nebula ( NGC 2392 ), also known as the Clown-faced Nebula, Lion Nebula, [ 4] or Caldwell 39, is a bipolar [ 5] double-shell [ 6] planetary nebula (PN). It was discovered by astronomer William Herschel in 1787. The formation resembles a person's head surrounded by a parka hood.
