In 1971 a Russian spacecraft attempted to photograph Mars, but the planet did not cooperate. Since then, we've learned more about the atmosphere of the red planet, and what makes it similar to, but very different from, our own.

We reveal the planetary enigmas on our doorstep and embark on the New Horizons voyage to photograph Pluto. Will our encounter with this tiny ball of ice and rock and the trillions of icy objects beyond it paint a clearer picture of how the planets came to be?

This is the story of pioneering missions to neighboring planets and our first glimpses of their awe-inspiring terrains. From the giant lava plains of Venus to the volcanoes on Mars that dwarf Mount Everest, we journey around the rocky planets and then to the icy moons of Jupiter, Saturn and beyond.

For centuries the giant planets floated on the fringes of the solar system as distant objects in the eyepieces of astronomers. But in December 1973 mankind had its first close encounter with Jupiter. We chart the story of our discovery of these massive planets, Jupiter, Saturn, Uranus and Neptune.

Earth has a companion in space so large that it rules our nights, our months, our ocean tides. Why Earth should have such a moon is one of the deepest mysteries of the Solar System. We tell the story of how the Earth’s satellite became the unlikely object of desire of the two Cold War superpowers.

For millennia humans have seen our star, the Sun, through the Earth’s atmosphere. But the Space Age has given us a new perspective that has revealed the many faces of the Sun in X-rays, ultraviolet/visible light, heat, and radio. We reveal hidden secrets of the Sun, like the power of solar wind.

As we continue to discover the diversity of life on Earth, we are forced to stop and marvel at how tenacious and inventive life is. So, as we forge onward in our robotic explorations of other worlds, we shouldn't be too surprised to find other places where conditions seem to be right for life.

The Sun created our Solar System and in a fit of cosmic cannibalism will engulf and destroy it. However, our Solar System will see many changes before the light of our star goes out. So, what will be happening with the planets over the next four billion years, before the Sun swallows us and them?

A hyperadvanced species makes their home on doomed exoplanet Terra, which orbits an aging star. Now they must colonize another world, using robots.

In the fall of 2020, a NASA spacecraft called OSIRIS-REx attempts to reach out and grab a piece of an asteroid named Bennu and bring it back to Earth. The OSIRIS-REx team has just three chances to extend its spacecraft's specialized arm, touch down for five seconds, and collect material from the surface of Bennu. Can they pull it off? NOVA takes you inside the mission as the team plans its approach: They must map the asteroid's surface, choose possible collection sites, and rehearse the risky maneuver. If the collection is successful, scientists could gain great insight into Earth's own origins—and even learn to defend against rogue asteroids that may one day threaten our planet.

Brian Cox continues his exploration of the solar system with a visit to a planet that dwarfs all the others: Jupiter. Its size gives it a great power that it has used to manipulate the other planets.

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.
