How Wiretapping Helped Transform Astronomy

World War I saw the use of early wiretapping, which led to the discovery of whistler-mode waves. These waves, caused by lightning and plasma interactions, became crucial tools in astronomy. They help us understand Earth's atmosphere, the Van Allen belts, and the magnetic fields of gas giants like Jupiter and Saturn. Probes like Voyager and Cassini have used these waves to study planetary atmospheres and interactions with moons. The research continues to provide insights into space phenomena.
