How do satellites send messages through space?

Professor Gizmo (Amazing Science Presentations) gives expert video advice on: Why do we need to wear a space suit in space?; Why do things float around in space?; Why do stars twinkle? and more...

Satellites will send messages through space the same way a radio station on earth sends signals to your radio, or television stations send signals to your television. It's electronic signals that travel through air, space, and so when there are satellites that are up in space and they're picking up information, that information is sent to us by a signal from the satellite to the earth that we receive with radio receiving equipment.
