The Russian Arctic is one of the world’s most extreme habitats, yet it is a haven for polar bears, lemmings, arctic foxes and walruses. In late August, massive muskoxen bulls gather together to compete for mating dominance. Each bull can weigh 400 kilogram’s and charge at a speed of 40 kilometres an hour; a head-to-head impact can be heard more than a kilometre away

How is the universe put together? How is it built? And how does it actually work? How the Universe Works Series 8 shows the inner workings of our planet, the solar system, the galaxies and the universe itself.
In the first episode, if a massive asteroid collides with earth, it could end life on our planet as we know it. New discoveries and cutting-edge tech reveal just how close we are to apocalypse and what it would take for the world's leading space agencies to stop it.

What are the latest discoveries in the deadly world of asteroids? Will a recently returned Japanese spacecraft become the first to bring an asteroid sample back to our planet? What would happen to America's East Coast if the massive asteroid impact that helped form Chesapeake Bay 35 million years ago struck today? And why did President Barack Obama choose an asteroid as the destination for the next great manned mission into space? Learning about these huge space rocks isn't just about science, it's about survival.

The documentary is to tell the dramatic story of the greatest natural disaster to shake the ancient world, a disaster that triggered the downfall of a civilisation and spawned a legend. Around 1620 BC a gigantic volcano in the Aegean Sea stirred from its 19,000-year slumber. The eruption tore the island of Thera apart, producing massive tsunamis that flooded the nearby island of Crete, the centre of Europe's first great civilisation – the Minoans. This apocalyptic event, many experts now believe, provided the inspiration for the legend of Atlantis. Based on the work of leading scientists, archaeologists and historians, this drama immerses viewers in the exotic world of the Minoans.

Without words, Ron Fricke shows us the world, with an emphasis not on 'where,' but on 'what's there.' It begins with morning, natural landscapes and people at prayer: volcanoes, water falls, veldts, and forests; several hundred Balinese Hindu men perform kecak, the monkey chant. Indigenous peoples apply body paint; whole villages dance. The film moves to destruction of nature via logging, blasting, and strip mining. Images of poverty, rapid urban life, and factories give way to war, concentration camps, and mass graves. Ancient ruins come into view, and then a sacred river where pilgrims bathe and funeral pyres burn. Prayer and nature return. A monk rings a huge bell; stars wheel across the sky.

The universe began with a massive expansion, billions and billions of years ago, and it continues to expand with every passing second. The idea that the universe, and man's very existence, began with a "Big Bang" is no longer a topic of debate among most scientists--it is essentially taken as fact.
