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.

Juno spacecraft discovered magnetospheric fireworks as magnetic field lines merge and snap between the gas giant and its largest moon. In June 2021, NASA’s Juno spacecraft flew close to Ganymede, Jupiter’s largest moon, observing evidence of magnetic reconnection...
