To land a human being on another celestial body will be the first step to living beyond our planet. The breathless pace and daring of the Apollo program sees NASA master previously unimagined tasks in the attempt to achieve the most incredible accomplishment in the history of human endeavor. From the ashes of tragedy on Apollo 1 emerges a determination that puts Apollo 8 in orbit around the Moon ahead of schedule. Apollo 9 and 10 each break bold new ground and pave the way for something few dared to believe was possible. When Neil Armstrong and Buzz Aldrin walk on the Moon and return safely to earth, the whole planet throws them a party.

For decades some have suspected that there might be others out there, intelligent beings capable of communicating with us, even visiting our world. It might sound like science fiction, but today scientists from across the globe are scouring the universe for signals from extraterrestrials. Scientists have been searching the cosmos for strange signals like the Lorimer Burst for more than 50 years. The film ends with scientists' latest search for extraterrestial intelligence. Horizon obtained exclusive access to film researchers at the Green Bank Telescope searching for radio signals from Tabby's Star, a star so mysterious that some scientists believe it might be surrounded by a Dyson Sphere, a vast energy collector built by advanced aliens.

How do astronomers make sense out of the vastness of space? How do they study things so far away? Today Phil talks about distances, going back to early astronomy. Ancient Greeks were able to find the size of the Earth, and from that the distance to and the sizes of the Moon and Sun. Once the Earth/Sun distance was found, parallax was used to find the distance to nearby stars, and that was bootstrapped using brightness to determine the distances to much farther stars.

In August 2018 NASA launched the first ever mission to a star. A historic quest to explore the last great frontier of our solar system - the sun. This will be the fastest man made object ever created. A spacecraft that will travel 450,000 miles per hour. It's ground breaking mission, to fly into the 'atmosphere' of our star and revolutionize our understanding of it. This documentary will celebrate this world changing event. Exploring the amazing science of our sun and going behind the scenes of the NASA mission to reach it. Timed to coincide with the arrival of the probe into the sun's atmosphere (Nov 2018) and the huge media spike this will create, this documentary will celebrate a key moment in human history, humanities first attempt to touch the Sun.
