The Sound of Saturn's Rings

This is the actual sound of Saturn's rings. They are radio emissions picked up by Cassini. The radio waves are then converted into audio through downshifting frequencies so we can listen.

"The sounds are actual recordings picked up by the Cassini spacecraft. I have heard the eerie audio before, but never had previously seen it paired up with moving images from the mission. The radio emissions, called Saturn kilometric radiation, are generated along with Saturn's auroras, or northern and southern lights. Cassini's Radio and Plasma Wave Science (RPWS) instrument takes high-resolution measurements that allow scientists to convert the radio waves into audio recordings by shifting the frequencies down into the audio frequency range."
