NOVA: The Planets

Professor Jim Al-Khalili shows how, by uncovering its secrets, scientists have used light to reveal the universe.

Black holes are one of the most destructive forces in the universe, capable of tearing a planet apart and swallowing an entire star. Yet scientists now believe they could hold the key to answering the ultimate question - what was there before the Big Bang? The trouble is that researching them is next to impossible. Black holes are by definition invisible and there's no scientific theory able to explain them. Despite these obvious obstacles, Horizon meets the astronomers attempting to image a black hole for the very first time and the theoretical physicists getting ever closer to unlocking their mysteries. It's a story that takes us into the heart of a black hole and to the very edge of what we think we know about the universe. Directed by: Stephen Cooter

Professor Brian Cox goes on a grand tour of the planet to explain how the Earth's beauty is created by just a handful of forces.

Professor of physics Jim Al-Khalili investigates the most accurate and yet perplexing scientific theory ever - quantum physics.

An epic journey around Mars — built from real satellite and rover data — revealing the red planet as you’ve never seen it before.

Chaos theory has a bad name, conjuring up images of unpredictable weather, economic crashes and science gone wrong. But there is a fascinating and hidden side to Chaos, one that scientists are only now beginning to understand. It turns out that chaos theory answers a question that mankind has asked for millennia - how did we get here?

what is everything, and what is nothing? Professor Jim Al-Khalili explores the true size and shape of the universe and delves into the amazing science behind apparent nothingness. EVERYTHING: what the universe might actually look like and the remarkable stories of the men and women who discovered the truth about the cosmos. NOTHING: science at the very limits of human perception, where we now understand the deepest mysteries of the universe lie. The quantum world of the super-small shaped the vast universe we inhabit today, and Jim Al-Khalili can prove it.

Oak Tree: Nature's Greatest Survivor. In this landmark new BBC documentary, entomologist George McGavin takes us on a fascinating journey through a year in the life of a 400-year-old oak tree.

Documentary presented by Professor Simon Schaffer which charts the amazing and untold story of automata - extraordinary clockwork machines designed hundreds of years ago to mimic and recreate life. The film brings the past to life in vivid detail as we see how and why these masterpieces were built. Travelling around Europe, Simon uncovers the history of these machines and shows us some of the most spectacular examples, from an entire working automaton city to a small boy who can be programmed to write and even a device that can play chess. All the machines Simon visits show a level of technical sophistication and ambition that still amazes today.

Alan Turing is the genius British mathematician who was instrumental in breaking the German naval Enigma Code during World War II, arguably saving millions of lives. Turing's achievements went unrecognised during his lifetime. Instead he ended up being treated as a common criminal, for being homosexual at a time when homosexual acts were a crime. In 1952, he was convicted of 'gross indecency' with another man and was forced to undergo so-called 'organo-therapy' - chemical castration. Two years later, he killed himself with cyanide, aged just 41. Alan Turing was driven to a terrible despair and early death by the nation he'd done so much to save.

Drama-documentary telling the gripping story of an encounter with an alien object travelling through the solar system.

Professor Jim Al-Khalili investigates the important concepts of energy and information.

Two-part documentary which deals with two of the deepest questions there are - what is everything, and what is nothing? Professor Jim Al-Khalili searches for an answer to these questions as he explores the true size and shape of the universe and delves into the amazing science behind apparent nothingness.
