The Comet's Tale

Prepare to immerse yourself in an alien world as if you were standing there yourself. Giant ice fountains rising over 100km high; an ocean hidden beneath a frozen crust of ice; storms twice the size of Earth coloured blood red by a vortex of dust and gases; immense volcanoes that could rip a planet apart — this series reveals the true and awesome beauty of our solar system. Using the very latest breathtaking images sent directly from space, groundbreaking CGI transforms the static into the dramatic. Travelling from the Sun to the far-out reaches of Neptune, the series has at its heart the latest scientific knowledge beamed back from the fleet of probes, rovers and telescopes currently in space, and offers a vivid and unprecedented tour of the world beyond our planet. Presented by Professor Brian Cox.

Who are we? Why are we here? Where do we come from? These are among the most enduring and profound questions we can ask, and it is an essential part of human nature to want to find the answers. We can trace our ancestry back hundreds of thousands of years to the dawn of humankind, but in reality our story extends much further back: it starts with the beginning of the universe. Professor Brian Cox tells the epic story of the universe and shows how its story is also our story.

When Neil Armstrong stepped onto the moon in 1969, America went down in popular history as the winner of the space race. But that history is bunk. The real pioneers of space exploration were the Soviet cosmonauts.  This remarkable feature-length documentary combines rare and unseen archive footage with interviews with the surviving cosmonauts to tell the fascinating and at times terrifying story of how the Russians led us into the space age. A particular highlight is Alexei Leonov, the man who performed the first spacewalk, explaining how he found himself trapped outside his spacecraft 500 miles above the Earth. Scary stuff.
