Journey from the Center of the Sun

   2014    Science
How does light escape from the sun? We take a journey from the center of the sun, following the path of light. We witness its fiery birth from in the core, its 430,000 mile battle against gravity and magnetism, and its escape from the solar surface.

Wild Russia: Siberia

   2009    Nature
From east to west, via mountains, volcanoes, deserts, lakes and Arctic ice, this breathtaking series uses stunning cinematography to chart the dazzling natural wonders of this vast country. Accounting for around 10 per cent of the world’s dry land, Siberia is famous as a brutally cold place. Yet it is home to a diverse range of habitats and animal life – including musk deer, camels, gazelles and the extraordinary Siberian salamander, which can spend years encased in -40°C ice and still survive.

Rainforest Home

   2020    Nature
Rainforests face more threats than ever before, but remain the last stronghold for some truly astonishing animal families. Today we know rainforests are some of the most wondrous and important habitats on Earth. It is the richest habitat on earth, teeming with millions of dramatic plants and animals. From giant landscape gardeners to a whole family supported by a single leaf, there are surprises at every turn.

Mission Blue

       History
Legendary oceanographer and TED prize winner Dr. Sylvia Earle is on a mission to save our oceans. Mission Blue is part action-adventure, part expose of an Eco-disaster. More than 100 scientists, philanthropists and activists gather in the Galapagos Islands to help fulfill Dr. Earle's lifelong wish: build a global network of marine protected areas, like underwater national parks, to protect the natural systems that keep humans alive.
As the expedition ends, the Deep water Horizon oil well explodes. With oil gushing into the Gulf of Mexico, Sylvia and an environmental dream team race around the world trying to defend her 'Hope Spots'.

Triumph

   2015    Science
David Attenborough concludes his epic history of the evolution of flight with an exploration of the highly advanced fliers that dominate our skies today – the extraordinarily diverse skills of the birds, and the sonar-guided precision of the bats. He encounters some of our planet’s most remarkable fliers – from peregrine falcons dive-bombing starlings over Rome, to hummingbirds hovering in the cloud forests of Ecuador. In a spectacular finale, he visits Gomantong cave in Borneo to witness the mass exodus of a million bats.

Black Holes: Heart of Darkness

   2021    Science
The centre of our galaxy is home to an invisible monster of unimaginable power – a supermassive black hole named Sagittarius A star, with four million times the mass of the Sun. Recent astronomical breakthroughs have confirmed not only that black holes like Sagittarius A star exist, but that these bizarre invisible objects may be the ultimate galactic protagonists.
Stunning CGI takes us back to witness the fiery origins of our galaxy’s black hole 13.6 billion years ago, when the early universe was home to colossal blue stars, and when they ran out of fuel, they collapsed under their own enormous mass, crushing down into an object so small and so dense it punched a hole in the fabric of the universe. Over billions of years, Sagittarius A star feasted on nearby gas, stars, and through cataclysmic mergers with other black holes. A breakthrough discovery by Nasa’s Fermi gamma-ray telescope has shown that our black hole had the power to sculpt the entire galaxy, creating vast bubbles of gas above and below our galaxy and even protecting stars systems as ours.
In a mind-bending conclusion, Brian Cox reveals how our modern understanding of black holes is challenging our concepts of reality to the breaking point. In trying to understand the fate of objects that fall into Sagittarius A star, scientists have come to a stunning conclusion: space and time, concepts so foundational to how we experience the world around us, are not as fundamental as we once thought.
