Question

Quizplus · Accepted Answer

Ganymede, a moon of Jupiter, has its own magnetic field, which interacts with charged particles from Jupiter's magnetosphere, leading to the formation of auroras in its atmosphere. This process is similar to how auroras are produced on Earth, but the source of charged particles is Jupiter's magnetosphere instead of the solar wind.
