Observations from the James Webb Space Telescope show how Jupiter reacts to its moons through auroral footprints, plasma interactions, and rapid electron flows detected in infrared measurements.

While Jupiter's main aurora has a great deal of hot materials, a snapshot showed a cold spot in Io's auroral footprint.

Using the Webb telescope, scientists discovered an unexpectedly cold, dense region within Io’s auroral footprint in Jupiter’s northern lights.
