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.

Construction of the famous Basilica in Barcelona, designed by Antoni Gaudi, was started in 1882. To this day, it has not been completed. The architecture is one of such creative madness, originality, and fantasy, that it has been declared a World Heritage Site by UNESCO. After years of piecing back together Gaudi’s master plan with advancements in computer technology and design, architects have been able to pursue the building, started 140 years ago. However, as construction progresses, some of its greatest challenges have yet to be surmounted, including the construction of 10 more spires. The team hopes to complete the masterpiece by 2026, Gaudi’s 100 year anniversary.
This film documents the complexities of respecting the original inspiration and techniques set forth by Gaudi over a century ago. Juxtaposing sequences shot in the midst of the cathedral as construction ensues, with reenactments and CGI images, the documentary draws you into Gaudi’s paradise on earth, from the origins of its inspiration to the most recent architectural additions.

In households across the world, pets are at the heart of family life. They share our homes, but how well do we really know them? In this series we'll dig deep into our pets' inner lives to discover the secrets they've kept hidden until now. From spectacular feats of communication to extreme athleticism, extraordinary intelligence and incredible super senses.
We'll meet remarkable pets from across the globe whose owners have harnessed their hidden skills and shared them with the world and will use groundbreaking technology to reveal how amazing their brains and bodies really are.
In the first episode, a base-jumping border collie, a bopping cockatoo, and racing rats show that animal intelligence can get a big boost in the right enriched environment.

Our frozen planet is changing. In this final episode, we meet the scientists and people dedicating their lives to understanding what these changes mean, not just for the animals and people who live there, but for the world as a whole.
Our journey begins in the Arctic, where every summer huge quantities of ice calve from the edges of Greenland’s melting glaciers. On top of the ice cap itself, glaciologist Alun Hubbard descends into a moulin to try to understand the mechanisms that are driving this historic loss of ice.
Elsewhere in the Arctic, it’s not just land ice that is disappearing. In the Gulf of St Lawrence, Canada, biologists are trying to find out how the loss of sea ice will impact the lives of baby harps. In Arctic Russia, with the loss of summer sea ice, more and more polar bears are arriving on the island of Wrangel. Here, a local ranger and scientists are braving the hungry bears to assess their future survival.
Loss of sea ice impacts not just wildlife but people too. In the remote community of Qaanaaq, Greenland, local Inuit hunters are finding the ice too dangerous to travel and hunt on, risking their traditional way of life. And these changes happening in the Arctic have the potential to affect people far beyond. On Alaska’s open tundra, bubbling lakes hint at the gases being released from the previously frozen soil, including the potent greenhouse gas methane.
There is one place where the full scale of a melting Arctic can be best witnessed - from space. Based in the International Space Station, astronaut Jessica Meir looks down at forest fires across Europe and reflects how our changing weather patterns are interconnected.
Rapid ice loss is also happening across the high mountains of the planet’s continents. Glaciologist Hamish Pritchard uses a sophisticated helicopter-strung radar system to try to quantify how much ice is left in the previously uncharted glaciers of the Himalayas. It’s important as, downstream, some 1.2 billion people rely on glacial meltwater as their primary source of fresh water.
Finally, in Antarctica, we meet Bill Fraser, who has dedicated 45 years of his life to studying the Adelie penguin. Over this period, he has witnessed changes in weather conditions and the extinction of entire colonies. These ‘canaries in the coal mine’ are a sign that all is not well, even in the remotest place on earth. And changes here have the potential to affect all of us, so an international group of scientists is on an urgent mission to assess the stability of a huge body of ice known as the Thwaites ice shelf. If this plug of ice melts and slips into the ocean, it will raise global sea levels, impacting coastal communities across the planet.
The unprecedented changes our scientists are witnessing may be profound, but there is hope that, through a combination of technology and willpower, there is still time to save what remains of our frozen planet.

Witness the secret powers of extraordinary animals, experience the world as they do and see the SUPER/NATURAL side of nature as never before. Executive produced by James Cameron and narrated by Benedict Cumberbatch, this series uses the scientific innovations and leading-edge filmmaking technology to reveal the secret powers and super-senses of the world’s extraordinary animals. See flowers in bee-vision to eavesdropping on conversations between elephant seals to soaring the length of a football field with glow-in-the-dark squirrels.
They say in nature that only the strongest survive. But when cooperation and communication bring animals and plants together and superpowers combine even the most vulnerable can become unstoppable. If you think you know nature, think again.

As tides rise and fall twice a day, vast amounts of water swirl around the earth. This is a huge energy source that's currently largely untapped. An estimated 3000 gigawatts are available to be harvested globally, enough to power a third of the earth's homes. Yet compared to wind and solar, the technology needed to harness tidal power is still in its infancy. The power of the ocean’s tides is the last great untapped energy source on Earth. From sub-sea kites to floating platforms, teams of engineers are racing to perfect the technology to harness the vast flows of water.
