"Astronomers have discovered new auroras over Jupiter's four largest moons: Io, Europa, Ganymede, and Callisto, observable at visible wavelengths. The new auroras reveal in greater detail the composition of the thin atmospheres of these Jovian moons, including traces of oxygen and sodium, but only minimal water vapor. "
Never expected that moons could have auroras

Wouldn't that just mean that the moon has a sufficiently sized magnetic field

Just curious, but wouldn’t it be Jupiters magnetosphere, causing the auroras?
