The worlds that surround our planet are all made of rock, but there the similarity ends. Some have a beating geological heart, others are frozen in time. Professor Brian Cox travels to the tallest mountain on Earth, the volcano Mauna Kea on Hawaii, to show how something as basic as a planet's size can make the difference between life and death.
To celebrate the Apollo moon landing's 50th anniversary, Professor Brian Cox and Dara O Briain travel to where the historic Apollo 11 mission began – Cape Canaveral in Florida. They hear first hand from astronaut general Charlie Duke what it was like to guide Neil Armstrong and Buzz Aldrin to the surface of the Moon in the Lunar Lander and how he followed in their footsteps three years later. They also look at the most exciting new developments and, with privileged access, they broadcast from the top of launch tower that is being prepared for crewed missions and from the assembly line of a spacecraft factory. They are joined by astrophysicist and medic Dr Kevin Fong and mathematician Dr Hannah Fry, who explore the latest developments in human space flight - from cutting-edge spacewalk technology to a future Mars buggy.

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.
Double stars are stars that appear to be near each other in the sky, but if they’re gravitationally bound together we call them binary stars. Many stars are actually part of binary or multiple systems. If they are close enough together they can actually touch other, merging into one peanut-shaped star. In some close binaries matter can flow from one star to the other, changing the way it ages. If one star is a white dwarf, this can cause periodic explosions, and possibly even lead to blowing up the entire star.
