Скачать или смотреть The Wow! Signal Explained 1977’s Mysterious Alien Radio Burst

In August 1977, astronomer Jerry Ehman detected a mysterious 72‑second radio signal while scanning the skies with Ohio State University’s Big Ear telescope. This powerful, narrowband burst — recorded at the hydrogen line frequency of 1420 MHz — stood out so dramatically that Ehman circled the data and wrote one word in the margin: Wow!
Known today as the Wow! Signal, this unexplained event remains one of the most compelling mysteries in the search for extraterrestrial intelligence (SETI). The signal appeared to come from the constellation Sagittarius, near the Chi Sagittarii star group, and carried the hallmarks of a deliberate transmission. Yet despite decades of follow‑up observations, it was never detected again.
In this documentary, we explore the story behind the Wow! Signal — from its discovery to the technical details of radio astronomy, the hydrogen line, and why scientists believe this frequency could be a universal channel for alien communication. We also examine the leading theories: comet emissions, satellite interference, and natural cosmic phenomena — and why none fully explain what happened that night.
Whether you’re a science enthusiast, a believer in extraterrestrial life, or simply curious about the universe’s greatest mysteries, this film blends cinematic storytelling with clear technical explanations to bring the Wow! Signal to life.
