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.
The islands of the Galapagos rose explosively from the ocean four million years ago. Although life would not seem viable in such a remote Pacific outpost, the first arrivals landed as the fires still burned. David Attenborough explores the islands for the animals and plants that descend from these pioneers: from the sea birds carrying the seeds that made a tentative foothold on these rocks, to equator-dwelling penguins and a dancing bird with blue feet. This is a story of treacherous journeys, life-forms that forged unlikely companionships, and surviving against all odds. It is the story of an evolutionary melting pot in which anything and everything is possible.

In March 2018 an international team of scientists gathered in a remote valley in the Canadian Rockies to conduct a unique experiment - to attempt to see into the heart of a massive avalanche to see if we can find ways to save lives in the future. Avalanches kill hundreds of people every year. Even in the UK 25 people have been killed by these forces of nature since the year 2000. But we know surprisingly little about them - why they happen or how they are able to produce destructive forces so powerful that they can flatten entire villages. Equally disturbing is the fact that climate change means that the pattern of avalanches is changing. They are occurring in places where they have never happened before. Finding out where might be in danger in the future is of vital importance. Answering all these questions could help save lives. The experiment attempts to provide those answers. The team of experts, gathered from all over the world, includes the programme's presenter Prof Danielle George. Her day job is studying space at Manchester University, but she is also a specialist in the design of experiments. She is even getting personally involved. As part of an experiment to test out safety equipment, Danielle puts on the latest breathing device intended to help you survive being caught in an avalanche. She then agrees to be buried under half a tonne of snow. The scientists hope to do what no one has ever managed before - to reveal the mysteries of an avalanche's destructive power by finding out what is going on at its very heart. Hitherto, our understanding of avalanches has been based on computer models - but these consistently underestimate the sheer power of these natural phenomena. To try and work out why, the scientists will conduct a range of cutting-edge tests, using the latest technology, including placing a car rigged with sensors right in the path of the avalanche. The plan is to set up the equipment and then unleash the avalanche by dropping explosives near the top of the slope. But the team are in a race against time. They have just three days to rig the mountain before the snow will come down the slope naturally. If they aren't ready in time, all their efforts will be wasted. Even worse, they are working in an active avalanche zone. For some scientists going out on the slopes to install their equipment means risking their lives. Interwoven with the main experiment are powerful and moving stories from survivors of these violent natural forces. We meet Casey George, whose two children were buried when an avalanche struck the small town of Missoula, Montana, completely out of the blue while they were playing. Their neighbour Fred Allendorf was inside his house when it was completely destroyed. The cataclysm claimed the life of his wife. Missoula had never been struck by an avalanche before. And no one could understand how a well-built house could be utterly demolished. The film meets British snowboarder Johno Verity, who was being filmed when an avalanche started right underneath him. His story provides clues as to what causes these disasters - a subtle change in the microscopic structure of snow deep beneath the surface. In a unique snow lab, where they can recreate different snow conditions, Danielle discovers exactly how snow can be transformed from something light and fluffy into a potential killer. And there is Elyse Saugstad, an expert skier who, despite years of experience, was caught unawares in an avalanche that killed three of her friends. All these stories emphasise just how unpredictable and devastating these events can be and why we need to understand and so be able to predict them better. In addition to being buried, Danielle George conducts another experiment into equipment that may help skiers survive being caught in an avalanche. Your chances of living rapidly diminish if you are buried for more than 15 minutes. She conducts a test with an inflatable airbag that is designed to keep you near the surface of an avalanche, making you easier to find. After two intense days of work by the scientific team, the experiment ends with over 1,000 tonnes of snow rushing down the mountainside. It triggers a whole host of censors and observational equipment. There is then a tense wait for results. But when they come, they are revealing. It seems that the team may have uncovered the first clues to an avalanche's unexplained power. If so, this could one day lead to significant breakthroughs in how we build houses and infrastructure that may lie in an avalanche's path and in how we devise safety equipment for skiers. It could be that this experiment will help save lives in the future.

Just outside Paris, inside a hi-tech vault, and encased in three vacuum-sealed bell jars, rests a small metallic cylinder about the diameter of a golf ball. It may not look like much, but it is one of the most important objects on the planet. It affects nearly every aspect of our lives including the food we eat, the cars we drive, even the medicines we take. It is the kilogramme, the base unit of mass in the International System of Units. This small hunk of metal is the object against which all others are measured. Yet over time, its mass has mysteriously eroded by the weight of an eyelash. A change that, unbeknownst to most, unleashed a crisis with potentially dire consequences. Follows the ensuing high-stakes, two-year race to redefine the weight of the world, and tells the story of one of the most important objects on the planet.
