Listening to Ganymede

This animation provides auditory and visual presentations of data collected by the Juno spacecraft’s Waves instrument during a flyby of the Jovian moon Ganymede. The animation is shorter than the duration of the flyby because the Waves data is edited onboard to reduce telemetry requirements.

The abrupt change to higher frequencies around the midpoint of the recording occurs as the spacecraft moves from one region of Ganymede’s magnetosphere to another. The actual frequency range of the data is from 10 to 50 kHz. The animation audio has been shifted to a lower range audible to human ears.
