The Juno spacecraft captured new images of a volcanic plume on Jupiter’s moon Io during a December 21 flyby. JunoCam, the Stellar Reference Unit (SRU), the Jovian Infrared Auroral Mapper (JIRAM), and the Ultraviolet Imaging Spectrograph (UVS) observed Io for over an hour, providing a glimpse of the moon’s polar regions as well as evidence of an active eruption.
