Voyager Plasma Sounds by NASA published on 2017-10-26T19:53:07Z These melodious tones are created at a special frequency in a plasma with a magnetic field. The frequency is set by the number of electrons in a given volume (the electron density) and the strength of the magnetic field. Hence, the frequency of these waves, called upper hybrid waves, can provide a very accurate measure of the density of the plasma; a fundamental property of the Jovian environment of interest to scientists. These emissions were acquired by Voyager 2 as it passed through the outer magnetosphere in 1979.
