The Magnetic Mystery of Jupiter's Moons The latest research from Kyoto University sheds new light on a longstanding question in planetary science: why do Jupiter and Saturn have such vastly different moon systems?
While Jupiter boasts an impressive 100 or so moons, including four large ones that are among the biggest in our solar system, Saturn is dominated by Titan, its largest and almost solitary moon.
This dichotomy has puzzled astronomers for years. Various theories have been proposed to explain it, but a new model developed by researchers from Japan and China suggests that magnetic fields may be the key.
