Its four big moons are visible with binoculars and change position from one night to the next, which is what Galileo noticed in 1610 and why they carry his name. The Great Red Spot is a storm wider than Earth, though it has been shrinking for a century. Its name is the oldest of any god in the sky. Jupiter, the Greek "Zeus pater" and the Sanskrit "Dyaus Pitar" are the same phrase, all three descended from one reconstructed form.
