Comet of the Century

It contains 99.9 percent of all the matter in our solar system and sheds hot plasma at nearly a million miles an hour. The temperature at its core is a staggering 27 million degrees Fahrenheit. It convulses, it blazes, it sings. You know it as the sun. Scientists know it as one of the most amazing physics laboratories in the universe.

Learn how seemingly small flashes of innovation have changed the course of civilization. Humanity from Space is an epic journey of discovery. Using the very latest mind-boggling data and astonishing CGI, the film traces the story of humankind’s ascent from hunter-gatherer to dominant global species.

Neil Armstrong's family and friends, many of whom have never spoken publicly before, tell the story of the first man to set foot on the moon. Drawing heavily on unbroadcast archive footage and the unique perspectives of the contributors, this is an exclusive account of Neil Armstrong's extraordinary life story. From his childhood during America's Great Depression to the heady days of the space programme, his historic first step on the Moon and his famously private later life. Seen through the eyes of those who were with him, the film explores the man behind the myth, a man who was very much a product of his time. The film goes beyond his days as an astronaut and shows that his life after the flight of Apollo 11 was, in many ways equally challenging, as Armstrong came to terms with life outside NASA and the relentless demands of fame until his death in August 2012.

Recently discovered footage reveals the secret history of NASA's first landing on the moon, and using this brand-new evidence, former astronauts and experts challenge everything known about the Apollo missions.
