Terraforming Mars

Could human settlements on Mars become reality as early as 100 years from now? Artificial micro organisms created with the latest techniques in synthetic biology could be used to produce resources such as iron, energy, and food directly on the planet itself. What would this new "Earth" look like?

Knowing without Seeing - The Science of Black Holes

Einstein, Oppenheimer, and other physicists and astronomers wrestled with the concept of Black Holes. With relentlessly powerful gravitational pull, black holes suck in anything that comes near them, but do they? As the study of black holes progresses, science finds more mysteries than solutions.

Monster Black Holes

There are Black Holes, and then there are Monster Black Holes -- containing several million to ten billion times the mass of our Sun! They've been discovered in the center of many galaxies. But they don't just absorb everything around them...in fact, they may be key to forming new galaxies.

Saturn's Moon Titan - Another Earth?

Even with a surface temperature of -180C, Saturn's moon, Titan, could be another Earth. There's evidence of dunes made of quantities of organic material that could contain the building blocks for DNA. Astrobiologists are conducting studies on the possibility that life could be present on Titan.

Signals from Outer Space?

Were "little green men" trying to contact us? Over 40 years ago, extremely constant pulses were detected reaching the Earth from outer space. It caused a great sensation. Using a radio telescope larger than a baseball field, scientists looked for the source of these signals and found - pulsars.

Blues for a Red Planet

The episode, devoted to the planet Mars, begins with scientific and fictional speculation about the Red Planet during the late nineteenth and early twentieth centuries (H. G. Wells' The War of the Worlds, Edgar Rice Burroughs' science fiction books, and Percival Lowell's false vision of canals on Mars). It then moves to Robert Goddard's early experiments in rocket-building, inspired by reading science fiction, and the work by Mars probes, including the Viking, searching for life on Mars. The episode ends with the possibility of the terraforming and colonization of Mars and a Cosmos Update on the relevance of Mars' environment to Earth's and the possibility of a manned mission to Mars.

Man Made Planet: Earth from Space

In 1972, the crew of Apollo 17 captured the iconic 'Blue Marble': the first photograph ever taken by an astronaut of the entire Earth. This photo had a profound effect on our perception of ourselves. Since then, Nasa has taken millions more. In this epic, powerful and revelatory documentary, a new generation of astronauts, including Tim Peake, use those images of the Earth from space to reveal the astonishing transformation humanity has wrought in the 45 years since 'Blue Marble'. Together, the astronauts provide an armchair tour of the change they've witnessed from orbit, as humankind etches our presence on the planet. Using stunning time-lapse sequences, the programme reveals how we are reshaping our world, for better and for worse: from the sprawling megacities of China to vast desert farms in the Middle East and from the melting snowcap of Kilimanjaro to giant solar arrays in Nevada.

8 Days: To the Moon and Back

Eight days, three hours, 18 minutes, 35 seconds. That is the total duration of the most important and celebrated space mission ever flown - Apollo 11 - when humans first set foot on the moon. It was a journey that changed the way we think about our place in the universe. But we only saw a fraction of what happened - a handful of iconic stills and a few precious hours of movie footage. Now it is time to discover the full story. Previously classified cockpit audio, recorded by the astronauts themselves, gives a unique insight into their fears and excitement as they undertake the mission. And dramatic reconstruction brings those recordings to life, recreating the crucial scenes that were never filmed - the exhilarating launch, the first sight of the moon, the dramatic touchdown and nail-biting journey home. Original archive footage from the Apollo programme is combined with newly shot film and cinematic CGI to create the ultimate documentary of the ultimate human adventure.
