Ganymede, Jupiter's largest moon, has long defied expectation by possessing a magnetic field that conventional planetary science struggled to explain. A new theory now suggests the moon's metallic core may not be a frozen relic but an actively forming structure, kept alive by tidal forces from Jupiter's immense gravity. This reframes not only Ganymede's geological story but also the broader human understanding of how worlds are built — and how long that building can take.
