Our planet is one in a billion. How incredible, awe-inspiring life is driven by its natural forces - and how we can ensure humans become a force for good. David Attenborough narrates a series revealing how the forces of nature drive, shape and support the Earth's great diversity of life.
The first edition examines volcanoes, which responsible for both for the planet's breathable atmosphere and the oceans, but are also the architects of the planet, with over 80% of the Earth's surface being the result of magma bursting up from the molten interior - providing a platform for life.

Voyager, the most ambitious space mission in history. They're the first probes to truly explore half the planets in our solar system: Jupiter, Saturn, Uranus and Neptune. These went from dots of light in the sky, to real worlds. The Voyager missions have ventured far beyond where other probes have explored. They're the first spacecraft to taste interstellar space, exploring further than any human made spacecraft has gone before. They are the greatest space mission ever. The legacy of Voyager is our remnant, it is our memory. It is a sampling of humanity that is out there now among the stars. And if they last until the death of the Universe, as the final stars fade, and everything goes dark, they will be humanity's final statement: ‘We were here.’
In the last episode of the season 10, experts explore the ultimate, ongoing mission of the Voyager spacecrafts.

Eternal life is humanity’s oldest dream. It may be finally coming true. Today, at least in the West, the quest for immortality has shifted from the metaphysical to the technical and the scientific. In this film we will investigate the advancement of this research in laboratories around the world. With cryonics technology improving, human cloning now possible, mind uploading and digital brain simulation thriving, reversing the aging of cells and organs feasible, immortality may seem right around the corner. In some countries, such as the US, Russia and Europe, private companies are financing and promoting the promise of immortality or at least a longer life expectancy. Are they selling a reality or utopia? We will meet scientists, neurophysiologists, computer specialists, geneticists, and biologists, and also hopefuls of immortal life, futurists, sociologists and businessmen. We will film different research laboratories and cities built for the aging; we will interview the experts as well as the anonymous men and women who speak about their relationship with life and death and those who simply embody it.

'Blood Brothers' follows the lives of two species, Paranthropus boisei and Homo habilis who embody two alternative ways of ape-man life. Although heavyset, with distinctive gorilla-like faces, the boisei are gentle characters. They live within a strict social structure and are led by a dominant male whose strength and power holds the group together. The habilis have taken a different approach to survival. They don't have the specialisms of the boisei but instead have developed into the archetypal jack-of-all-trades, inquisitive scavengers prepared to try almost anything to survive. Tough, active, gregarious and noisy, they are always on the move and always alert to the possibility of a meal. But in the near drought of the dry season the habilis are struggling. It seems as if their way of life cannot help them when conditions are tough.

It's 3.5 million years ago and in East Africa a remarkable species of ape roams the land. Australopithecus afarensis has taken the first tentative steps towards humanity by standing and walking on two legs. The rift valley was forming, and the rain forests dying as Africa dried out - turning the landscape into a mosaic of scattered trees and grass. In this new environment afarensis found it more efficient to move about on two legs rather than four.

One and a half million years ago, a new breed of ape-man walks the land. In southern Africa, Homo Ergaster has taken the next step to becoming human. They have long, modern looking noses, which cool air as they breathe. Their hairless bodies, with millions of tiny sweat glands, mean they don't pant anymore to control their temperature - they sweat. And, above all, they have big brains - nearly two-thirds the size of ours.
