Juno Probe Reveals Extensive Lava Lakes on Jupiter's Moon Io

New infrared imagery from NASA's Juno spacecraft provides unprecedented insights into Io's volcanic activity.

Juno's infrared instrument JIRAM detected widespread lava lakes across Io's surface.
The data revealed that around 3% of Io's surface is covered by molten lava lakes.
Infrared images show a thin circle of lava at the borders of these lakes, suggesting a balance between erupted and recirculated magma.
Researchers propose two hypotheses for the observed volcanic activity involving crust deformation and magma upwelling.
Continued flybys are expected to yield more detailed information on Io's volcanic processes.
