Sounds of Space: New 'Chorus' Recording By RBSP's EMFISIS Instrument
http://www.nasa.gov/mp3/687631main_6...s_chorus_1.mp3

Audio (wav or mp3) of the phenomenon known as "chorus" radio waves
within Earth’s magnetosphere that are audible to the human ear, as
recorded on Sept. 5, 2012, by RBSP’s Electric and Magnetic Field
Instrument Suite and Integrated Science (EMFISIS). Five six-second
"events" are captured in this sample, and they are played end-to-end,
one right after the other, without gaps. Credit: University of Iowa.

NPR: NASA’s Radiation Belt Storm Probes mission was launched 30 August
to study the Van Allen Radiation Belts, a hazardous region of space
around Earth that is filled with high-energy particles. Recently, the
probes recorded the clearest radio signals yet emitted by the energetic
particles in Earth’s magnetosphere.
