Yet historically, the ancient Egyptians were the first to document the interpretations of dreams. The Chester Beastly Papyrus is one of the earliest documents on dreams. And their dreams were closely linked with divination and soothsaying.
Pluto's baby twin moons, formerly known as S/2005 P 1 and S/2005 P 2, have been christened Nix and Hydra. The objects, discovered last year by the Hubble Space Telescope, received their names from the International Astronomical Union (IAU). A formal announcement will be issued this Friday, 23 June.

In mythology, Pluto ruled the underworld. Nyx was the goddess of night and the mother of Charon, the boatsman who takes souls across the River Styx and into Pluto's grasp. Pluto's large satellite, discovered in 1978, is called Charon. Because an asteroid with the name Nyx already exists, the IAU decided to use a slightly different spelling for the inner one of the two small Plutonian moons, to avoid confusion. Hydra was the mythological nine-headed serpent that guarded the underworld. A large but inconspicuous constellation in the spring sky also bears this name.
Hydra is a monster with the body of a nine-headed serpent, seen as appropriate for the outermost moon of Pluto, the ninth planet in the solar system.
