I recommend this Top Ten List of Strange Space Noise recorded over the years by scientists and researchers. Marvel at the mutterings of an actual Black Hole! Hear the astonishing sonic wash of space telemetry (Brief Interruption Here. Here is an explanation of Space Telemetry: Data Transmission Space telemetry transmits information in the form of a radio signal. Sensors on the spacecraft collect analog data–a photograph of Mars for example–and send it back to Earth. Early space telemetry systems used Pulse Position Modulation (PPM) and Pulse Width Modulation (PWM) to transmit data.) in all its glory! You get the idea. [More]
