JWST Uncovers Puzzling Variability in Jupiter's Aurora
First infrared spectra of Jupiter's auroral bright spots reveal extreme temperature and density swings that challenge existing models.
Key Takeaways
- JWST captured first infrared spectra of Jupiter's moon-generated auroral bright spots
- Io's auroral footprint shows extreme temperature and density variability on hourly timescales
- Findings suggest Jupiter's magnetospheric dynamics are more complex than current models predict
