Findings from NASA's Juno spacecraft

Juno has been orbiting Jupiter for three years, gathering data on its radiation belts, magnetic field, and interior structure. Despite initial concerns about radiation, Juno remains operational, revealing new insights into Jupiter's atmosphere and magnetic phenomena. The mission has also provided detailed observations of Io's volcanic activity and Jupiter's auroras. Juno's findings challenge previous theories about Jupiter's core and atmosphere, suggesting a more complex structure. The mission continues to enhance our understanding of Jupiter and its role in the solar system.
