In June 2021, NASA’s Juno spacecraft flew close to Ganymede, Jupiter’s largest moon, observing evidence of magnetic reconnection. An SwRI-led team used Juno data to characterize the magnetic topology and electron flow direction for two different reconnection scenarios at Ganymede’s magnetopause. The yellow dashed line indicates Juno’s trajectory.
