Saturn Aurora Sounds

NASA’s Cassini spacecraft has been detecting intense radio emissions from Saturn’s aurorae, where magnetic field lines thread the polar regions. These signals have been shifted into the range of human hearing and compressed in time. The complex radio spectrum with rising and falling tones, is very similar to Earth’s auroral radio emissions. These structures indicate that there are numerous small radio sources moving along magnetic field lines threading the auroral region. Time on this recording has been compressed, so that 73 seconds corresponds to 27 minutes. Since the frequencies of these emissions are well above the audio frequency range, we have shifted them downward by a factor of 44.
