Ganymede’s magnetic field
This is a sketch of the magnetic field lines around Ganymede, which are generated in the moon's iron core. Hubble Space Telescope measurements of Ganymede's aurorae, which follow magnetic field lines, suggest that a subsurface saline ocean also influences the behavior of the moon's magnetosphere.
