Audio: Som ET - 83 - Earth

Audio recordings of NASA's Van Allen Probes/Waves plasma wave observations.

The Van Allen Probes EMFISIS Waves instruments detect electric and magnetic components of plasma waves and radio waves that range through frequencies that include those audible to humans. Although these differ from the pressure waves that we normally think of as sound, they can be used to drive speakers and produce sounds we can hear.
