Ganymede Auroral Footprint

Caption

NASA’s Juno spacecraft flew through the intense beam of electrons traveling from Ganymede, Jupiter’s largest moon, to its auroral footprint on the gas giant. SwRI scientists used the resulting data to connect the particle population traveling along the beam with associated auroral emissions to unveil the mysterious processes creating the shimmering lights.
