Encyclopedic overview
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 in the 1864 General Catalogue as GC 2102; this became NGC 3242 in J. L. E. Dreyer's New General Catalogue of 1888.
