Via Boing Boing, we are quite the privileged witnesses to a solar eclipse caused by the shadow of Io moving across the dappled clouds of Jupiter (previously). One of the Galilean Satellites discovered by the artist and polymath in 1610 and designated Jupiter I, this innermost moon is the most dehydrated body known and also the most geologically (ionically) active with over four hundred volcanoes driven by gravitation pressures and tidal heating from its host world.
The mythological figure (whose name means moon) was one of Hera high priestesses at Argos and caught the wandering eye of Zeus, whose advances she steadily rebuffed. Unhappy with the extra divine scrutiny, Io was turned out of the temple, whereupon Zeus transformed her in a resplendent white heifer in order to hide her from his wife. The deception was rather transparent and Hera dispatched an obnoxious gadfly to pester the poor cow and drive her to wonder the Earth without rest.
She crossed from Europe into Asia at the Bosporus (oxford), where she met Prometheus chained, whom despite his own torture was able to console Io was the prophesy that her humanity would be restored. Returning to Greece, prodded still ever onward, she sought relief by taking the sea route to Egypt (the Ionian), when upon arrival, Zeus was able to disenchant her. With Zeus, Io bears Apis, king of Egypt—identified with the historical pharaoh Apophis (*1575 – †1540, BC), and primogenitor of many of the ancient, semi-legendary great houses of the Mediterranean.  Among the most frequented bodies in the Solar System and well studied, inhospitable Io has been rather ignominiously described as having (the namesake—that is) the colour of pizza.
