Juno Waves Audio Clip

As NASA's Juno spacecraft crossed into Jupiter's immense magnetic field the Waves instrument recorded the onset of "trapped continuum radiation", a result of multiple reflections from the boundaries of a low-density plasma cavity inside Jupiter's magnetosphere.

The video presents a frequency-time spectrogram with a moving cursor that shows the time position of the audio track. Time advances from left to right along the horizontal axis, frequency ranges from low to high frequencies along the vertical axes, and the amplitude of the signals is color coded with blue indicating weak signals and red indicating strong signals.
