The most fascinating detail here isn't just the images, but the temperature data. JWST actually found a localized 'cold spot' (538K) right in the core of Io's magnetic footprint, surrounded by a much hotter main aurora. The fact that the ion density shifts so drastically in a matter of minutes is wild.
