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.

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.

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

“Our findings suggest that Jupiter’s moons did not form as chemically pristine worlds,” Mousis said. “Instead, they may have accreted, or accumulated, a significant inventory of COMs at birth, ...
