A catastrophe still reverberating today with Chernobyl on the front line of war. Formerly secret KGB files reveal the astonishing truth about the 1986 explosion of the Chernobyl nuclear reactor in Ukraine, with leading experts and eyewitness accounts.
Newly declassified evidence from KGB archives reveals that the KGB had concerns about the safety of the Chernobyl nuclear plant even as it was being built. The film includes first-hand accounts from survivors, including Oleksiy Ananenko, who braved radioactive waters to prevent a second explosion, and Maryna Sivets, whose unborn child's life was put at risk.

In the second episode, panic strikes the community as a full-blown catastrophe looms. Locals mobilize to confront the authorities and protest the nuclear power industry.
Twenty-eight hours after the accident began, the lieutenant governor appeared at a news briefing to say that the plant's owner had assured the state that 'everything is under control'. Later that day, Scranton changed his statement, saying that the situation was 'more complex than the company first led us to believe'. There were conflicting statements about radioactivity releases. Schools were closed and residents were urged to stay indoors. Farmers were told to keep their animals under cover and on stored feed.

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. '

Inside the heart of the atom, its nucleus houses energy. This hidden treasure was forged billions of years ago in distant stellar furnaces. The secret of starlight is nothing to fool with. It can bring a civilization to life and it can burn it to the ground.
Two atoms from different parts of the universe meet on a small planet. A deadly embrace between science and state altered the fate of the world and a gripping cautionary tale of others who grew used to living in the shadow of grave danger until it killed them all except one.

Recently, the Event Horizon Telescope project captured the first image ever of a black hole. Now, new discoveries might finally reveal how supermassive black holes are made, and using the latest technology, experts are on the verge of understanding how these monsters grow and how they affect life on our planet.
Supermassive black holes: Gargantuan monsters that lurk at the center of galaxies. Right now you are travelling at half a million miles an hour around a giant black hole four million times the mass of the sun. But there's a mystery about these colossal beasts. We have no idea where they came from. How did they get so big so quickly?

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.
