“By combining data from this flyby with our previous observations, the Juno science team is studying how Io’s volcanoes vary. We are looking for how often they erupt, how bright and hot they are, how the shape of the lava flow changes, and how Io’s activity is connected to the flow of charged particles in Jupiter’s magnetosphere.”

Coming within roughly 930 miles from the surface of the most volcanic world in our solar system, the pass is e
