A Signal So Precise It Couldn't Be Natural

In 1967, a Cambridge student detected a signal so mechanical that an alien source couldn't be ruled out. Jocelyn Bell was studying quasars with radio telescopes — using the one kind of light that crosses billions of light-years without being blocked by dust and gas — when a pulse appeared, arriving exactly every 1.3373 seconds. Nothing natural was supposed to do that. Her supervisor labelled it LGM-1: Little Green Men. He was only half joking. Then Bell found a second source, and a third. This clip tells the full story of how clockwork radio pulses fooled astronomers.
