The Celts - one of the world's most mysterious ancient people. In Britain and Ireland, we are never far from our Celtic past but in this series Prof. Alice Roberts and archaeologist Neil Oliver travel much further afield, discovering the origins and beliefs of these Iron Age people in artefacts and human remains right across Europe, from Turkey to Portugal. What emerges is not a wild people on the western fringes of Europe, but a highly sophisticated tribal culture that influenced vast areas of the ancient world - and even Rome". Rich with vivid drama reconstruction, we recreate this pivotal time and meet some of our most famous ancient leaders - from Queen Boudicca to Julius Caesar - and relive the battles they fought for the heart and soul of Europe. Alice and Neil discover that these key battles between the Celts and the Romans over the best part of 500 years constituted a fight for two very different forms of civilisation - a fight that came to define the world we live in today. In the first episode, we see the origins of the Celts in the Alps of central Europe and relive the moment of first contact with the Romans in a pitched battle just north of Rome - a battle that the Celts won and that left the imperial city devastated.

Sir David Attenborough journeys to both Polar Regions to investigate what rising temperatures will mean for the people and wildlife that live there and for the rest of the planet. David starts out at the North Pole, standing on sea ice several metres thick, but which scientists predict could be Open Ocean within the next few decades. The Arctic has been warming at twice the global average, so David heads out with a Norwegian team to see what this means for polar bears. He comes face-to-face with a tranquilised female, and discovers that mothers and cubs are going hungry as the sea ice on which they hunt disappears. In Canada, Inuit hunters have seen with their own eyes what scientists have seen from space; the Arctic Ocean has lost 30% of its summer ice cover over the last 30 years. For some, the melting sea ice will allow access to trillions of dollars worth of oil, gas and minerals. For the rest of us, it means the planet will get warmer, as sea ice is important to reflect back the sun's energy. Next David travels to see what's happening to the ice on land: in Greenland, we follow intrepid ice scientists as they study giant waterfalls of meltwater, which are accelerating iceberg calving events, and ultimately leading to a rise in global sea level. Temperatures have also risen in the Antarctic - David returns to glaciers photographed by the Shackleton expedition and reveals a dramatic retreat over the past century. It's not just the ice that is changing - ice-loving adelie penguins are disappearing, and more temperate gentoo penguins are moving in. Finally, we see the first ever images of the largest recent natural event on our planet - the break up of the Wilkins Ice Shelf, an ice sheet the size of Jamaica, which shattered into hundreds of icebergs in 2009.

Three years in the making, Francis Whately’s film is a social and musical history of (probably) the world’s greatest music festival, as told by its principal curators, Michael and Emily Eavis, and many of the key artists who’ve appeared there between 1970 and 2019 – Billie Eilish, Thom Yorke, Florence Welch, Dua Lipa, The Levellers, Aswad, Orbital, Fatboy Slim, Linda Lewis, Noel Gallagher, Ed O’Brien, Chris Martin, Stormzy and more.
Balancing the driving forces of social conscience and hedonism, Glastonbury has always been both a world apart and a barometer of the state of the nation. Looking at the hippie days, CND, the contribution of the travellers, dance music, Britpop, The Wall, the impact of television and the first black British solo headliner, this film takes viewers backstage and deep into the archive to reveal the forces that have driven this alternative nation between utopia and dystopia, the greatest night of your life and a muddy field in the middle of nowhere.
This is not a chronological plod through the festival’s evolution so much as a thematic and story-driven exploration of the peaks and troughs, and the agonies and ecstasies, that have shaped Glastonbury’s 50 years and counting.

Even 2,000 years after his death, General Hannibal's battle strategies are still studied today. But of all his military feats, perhaps his greatest was leading his massive Carthaginian army of men and three-dozen elephants across the Alps and into the heartland of Rome in 218 B.C. Until now, the route they took has been a matter of dispute, but thanks to modern-day technology, geomorphologist Bill Mahaney and microbiologist Chris Allen believe they've accurately traced this ancient journey.

It is 200 years before the birth of Christ and Rome is the new superpower of the ancient world. She believes she is invincible - but one man is destined to change that. He is a man bound by oath to avenge the wrongs inflicted on his home and, in pursuit of revenge, he will stop at nothing. This featured docudrama explores the man behind the myth, revealing what drove the 26-year-old to mastermind one of the most audacious military moves in history. With 40,000 soldiers and 37 elephants, he marched 1,500 miles to challenge his enemies on their own soil. It was an act so daring that few people believed it possible.
‘Hannibal: Rome Worst Nightmare’ combines drama, the latest historical research and state-of-the-art CGI to bring this spectacular story to life.

Sagan discusses comets and asteroids as planetary impactors, giving recent examples of the Tunguska event and a lunar impact described by Canterbury monks in 1178. It moves to a description of the environment of Venus, from the previous fantastic theories of people such as Immanuel Velikovsky to the information gained by the Venera landers and its implications for Earth's greenhouse effect. The Cosmos Update highlights the connection to global warming.
