[en] Peculiar features of Jupiter's auroral emissions, with no counterpart at Earth, are the auroral structures induced by the interaction of the Galilean moons Io, Europa, and Ganymede with Jupiter's magnetosphere. These footprints are observed in the ultraviolet, infrared, and radio wavelengths as the result of the local sub-Alfvénic electromagnetic interaction between each moon and the magnetospheric plasma flow. Since July 2016, these interactions and the resulting auroral emissions have been characterized in detail by the Juno mission thanks to its highly-eccentric, polar orbit around Jupiter. The spacecraft enables both remote-sensing observations, including UV, IR, and radio measurements, and in situ observations, with plasma and wave measurements obtained along the magnetic flux tubes connecting the moons to their auroral footprints.
