Data used to generate this composite image of volcanic activity on the Jovian moon Io was obtained by the JIRAM (Jovian Infrared Auroral Mapper) instrument aboard NASA's Juno spacecraft during a flyby of the moon on Oct. 16, 2021. JIRAM took the four images over a short time interval to observe volcanic activity on the moon from different view angles.

JIRAM data collected over time could provide information on changes to Io's surface, including the number of active volcanoes or variations in their intensity. JIRAM "sees" infrared light not visible to the human eye. In this composite image, the measurements of thermal emission radiated from the planet were in the infrared wavelength of around 5 microns.
