Jupiter is a wonderful object for radio study. It is somewhat predictable and yet often surprising in its violent outbursts below 40 MHz. You can receive Jupiter using relatively simple equipment or you can construct complex spectrograph receivers and build monstrous antenna arrays to capture its more subtle messages. The complex relationship between the gas giant planet and its volcanic moon Io is not completely understood, but we do know these bodies work together to produce „radio noise storms“ as they pirouette through space.
