Jupiter's moons leave cold 'footprints' in the planet's auroras, James Webb Space Telescope finds

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.

The JWST Reveals Some Puzzling Surprises in Jupiter's Northern Aurora

Jupiter's powerful, continuous aurorae dwarf those of Earth. Scientists know that Jupiter's Galilean moons created bright spots on Jupiter's northern aurora. The JWST observed these bright spots and generated infrared spectra of them for the first time. Those observations showed that Io's bright spot is extremely variable in both temperature and density, and researchers want to know why.
