Exciting Discoveries on Jupiter's Largest Moon

Ganymede, Jupiter's largest moon, is unique with its vast water ocean and magnetic field. Despite its potential for life, the thin oxygen atmosphere and deep ocean pressure make it unlikely. Ganymede's magnetic field, discovered in 1996, is a mystery as it shouldn't exist given its size and composition. Tidal heating from its eccentric orbit and gravitational interactions with other moons may keep its core liquid, explaining the magnetic field. Future missions like the Juice spacecraft aim to uncover more about Ganymede's mysteries.
