NGC 3242, commonly known as the Ghost of Jupiter, is a planetary nebula located in the constellation Hydra discovered by William Herschel in 1785.
The nebula measures around two light years long, and contains a central white dwarf with an apparent magnitude of eleven.
The inner layers of the nebula were formed some 1,500 years ago. The two ends of the nebula are marked by lobes of fast moving gas showing up in subtle red.
