Juno Discovers Rare Plasma Waves in Jupiter’s Auroras

Speedy Summary

• Using data from NASA’s Juno spacecraft, researchers have detected an unusual type of plasma wave in Jupiter’s auroral zones, specifically near its north pole.
• Plasma waves in this region have very low frequencies due to the combination of low density polar plasma and Jupiter’s strong magnetic field.
• Unlike Earth’s auroras that form donut-shaped activity patterns around polar caps, Jupiter’s magnetic field allows particles to flood directly into its polar cap.
• Infrared images from the James Webb Space Telescope have contributed to aurora studies, but Juno is the first spacecraft in a polar orbit tailored for such analysis on Jupiter.
• Thes findings add new knowledge about how plasma behaves differently under varying magnetized planetary conditions compared to Earth. Researchers aim to collect more data through Juno’s continuing mission.
• results were published in Physical Review Letters,dated July 16,2025.
