While the Big Bang is often credited as the moment of creation, the universe actually plunged into a 100-million-year period of absolute pitch-black darkness known as the Cosmic Dark Ages. This documentary follows leading astrophysicists and astronomers as they use supercomputers, robotic sky-mapping, and giant radio telescopes in Australia's remote outback to uncover "Cosmic Dawn"—the moment the very first stars ignited. By simulating primordial hydrogen clouds, discovering 13.6-billion-year-old second-generation stars, and mapping how massive ultraviolet "bubbles" cleared a dense cosmic fog, scientists reveal how these short-lived stellar giants forged the heavy elements that made planets, chemistry, and life possible.
