Juno Faint Aurora

Caption

The SwRI-led Ultraviolet Spectrograph (UVS) orbiting Jupiter aboard NASA's Juno spacecraft allowed scientists to discover faint aurora features likely triggered by charged particles coming from the edge of Jupiter's massive magnetosphere. This occurrence, shown in the false color series of images recorded 30 seconds apart (red panels), displays the characteristically ring-like emissions, expanding rapidly over time.
