How It Works

The sound of Saturn’s rings

Dr Don Gurnett (University of Iowa) “That sound that you heard is the sound of radio emissions from Saturn. And I think you could very definitely hear that beat. The sound that you’re hearing was speeded up considerably. We had five days that were played in only 15 seconds. And the beat period you could hear, that is the rotation of Saturn. It essentially gives us the length of the day at Saturn.”
