Summary:

- NASA's Juno mission has provided new insights into the volcanic activity on Jupiter's moon Io, the most volcanically active body in our solar system.
- Juno's data has revealed that the intense heat and lava flows on Io are generated by the constant flexing of the moon's interior, which is driven by the powerful gravitational forces exerted by Jupiter and the other Galilean moons.
- The findings from Juno's observations have improved our understanding of the internal structure and dynamics of Io, which could provide valuable information about the formation and evolution of Jupiter's moons and the Jovian system as a whole.
