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

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.

An international team of scientists, led by PhD researcher Katie Knowles from Northumbria University, has made groundbreaking ...

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

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.

Images captured in 2023 by NASA's James Webb Space Telescope of the massive aurora lights on Jupiter reveal unexpected activity in the gas giant's atmosphere. (Video: NASA, ESA, CSA, STScI) ...
