35 years after the Chernobyl disaster, Ben Fogle travels to the most radioactive place on Earth. He spends a week living alone inside the Chernobyl Exclusion Zone, gaining privileged access to the doomed Control Room 4 where the disaster first began to unfold.
'The planet faces unprecedented challenges - many of them, like Chernobyl, of our own making. What I've discovered in Chernobyl is that nature's reclaiming it. This is the greatest, accidental rewilding project of the globe. For me, the really exciting part of the Chernobyl story is the accidental hope that came from it. '

In August 1977, the Big Ear Radio-telescope in Ohio received a strange signal from the Sagittarius constellation while searching for intelligent extra-terrestrial life. It had a duration of 72 seconds and an intensity 30 times higher than usual. Named the Wow signal, it is still being considered as one of the best examples of having being sent by intelligent extraterrestrial life. But, nothing has revolutionised the search of extra-terrestrial intelligent life as much as the recent discovery by the Kepler Satellite, of thousands of Earth-like planets where life could be possible. Join the debate with this stunning documentary, as we ask Is Anybody Out There?

A deep sea diver is stranded on the seabed with 5 minutes of oxygen and no hope of rescue. With access to amazing archive this is the story of one man's impossible fight for survival.
Chris Lemons were carrying out repairs 100m below the surface of the North Sea, supported by the vessel Bibby Topaz. The vessel's dynamic positioning system failed, causing it to snap the umbilical tether that provided Lemons oxygen, as well as hot water to heat his suit, power for his light, and a radio link to the surface. He was left with only the few minutes of breathable gas contained in the cylinders he wore on his back.
For reasons that are unclear, Lemons survived for around 30 minutes while he was located by a remote underwater vehicle and then by Yuasa, who was able to pull him back onboard the diving bell. The documentary uses genuine footage and audio recorded at the time of the accident on the divers' radios and body cameras, supplemented with interviews of several of the individuals involved, as well as some reconstructed footage, to tell the story of the accident.

This documentary looks at the remarkable genius of Orson Welles on his centenary - the enigma of his career as a Hollywood star, a Hollywood director (for some a Hollywood failure), and a crucially important independent filmmaker. Orson Welles's life was magical: a musical prodigy at age 10, a director of Shakespeare at 14, a painter at 16, a star of stage and radio at 20, romances with some of the most beautiful women in the world, including Rita Hayworth. His work was similarly extraordinary, most notably Citizen Kane, (considered by many to be the most important movie ever made), created by Welles when he was only 25. In the years following Citizen Kane, Welles's career continued to change as he made film after film (some never finished, many dismissed) and acted in other projects often to earn money in order to keep making his own films. Magician features scenes from almost every existing Welles film, from Hearts of Age, (which he made in a day when he was only 18 years old) to rarely-seen clips from his final unfinished works like The Other Side of the Dream, The Deep, and Don Quixote, as well as his television and commercial work.

It bursts from the Sun with the power of ten thousand nuclear weapons... and when it hits our planet, it could create the largest disaster in recorded history. A magnetic storm from the Sun could wipe out electrical power, television, radio, military communication, and nearly every piece of electronics in the Northern Hemisphere. It's a "Solar Katrina" -- a planet-wide "hurricane" of magnetic forces that scramble all 21st Century technology, possibly for good. What causes this magnetic superstorm? Why is magnetism so powerful -- and yet so poorly understood? And is there anything we can do to prevent the Magnetic Storm?

Deep in the mountains of West Virginia, the Green Bank Observatory has been receiving a mysterious signal from deep space. A team of astronomers has been detecting high-energy bursts erupting from unknown sources far off in space since years ago. But one of them is different from the rest. They call it FRB 121102.
What is actually giving rise to this very powerful flash? Could this be a message from an advanced civilization, or is it a much stranger and violent occurrence? Visit the largest steerable radio telescope on the planet for answers.
