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

The findings suggest that the gas giant's atmosphere reacts instantly to activity involving its orbiting moons.

Never-before-seen temperature and ion density measurements reveal that the effect of Jupiter's moons on its aurora are more complicated than scientists thought.

New observations have ruled out the chances of an asteroid hitting the moon in 2032, according to scientists using the James Webb Space Telescope.

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.
