Liz Bonnin presents a Horizon special about a rare and beautiful event in our solar system, one that we should all be able to see for ourselves - the transit of Venus across the face of the sun.

Presented by Professor Iain Stewart, this film explores what meteorites and asteroids are, where they come from, the danger they pose, and the role they have played in Earth's history.

On the 15th December, Tim Peake will launch into space to be Britain's first astronaut on board the International Space Station. For the past two years, Tim has been filming a video diary for Horizon showing the risks, pressures and rigorous training required to launch into space. Horizon also talks exclusively to his wife and two children as they prepare to wave him goodbye on his voyage to space.

Horizon takes the ultimate trip into the unknown, to explore a dizzying world of cosmic bounces, rips and multiple universes, and finds out what happened before the big bang.

There is a strange and mysterious world that surrounds us, a world largely hidden from our senses. The quest to explain the true nature of reality is one of the great scientific detective stories.

Until very recently the whole idea of the multiverse was dismissed as fantasy. Horizon asks whether multiple universes exist and, if so, which one we are actually in.

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?

Famed for their ability to inflict Armageddon from outer space, asteroids are now revealing the secrets of how they are responsible for both life and death on our planet.

New planets are now being discovered outside our Solar System on a regular basis, and these strange new worlds are forcing scientists to rewrite the history of our own Solar System. Far from a simple story of stable orbits, the creation of our Solar System is a tale of hellfire, chaos and planetary pinball. It’s a miracle our Earth is here at all.

Professor Jim Al Khalili delves into over 50 years of the BBC science archive to tell the story behind the emergence of one of the greatest theories of modern science, the Big Bang.

The definitive story of going to the moon, told by those who went. Between 1969 and 1972 an elite group of men achieved an incredible dream. They were, and remain, the only human beings to set foot on a planet other than our own.

Using cutting edge visual effects and CGI, this scientific visual extravaganza creates the first accurate non-stop journey from here to the edge of the universe

Two-part series in which Professor Jim Al-Khalili shows how, by uncovering its secrets, scientists have used light to reveal almost everything we know about the universe.

Professor Jim Al-Khalili tells the story of how we went from thinking we were close to a complete understanding of the universe to realising we had seen almost none of it. Today, our best estimate is that more than 99 per cent of the cosmos is hidden in the dark, invisible to our telescopes and beyond our comprehension.

In 2009, NASA celebrated the 40th anniversary of the first moon landing. This documentary series offers audiences a unique chance to glimpse an astronaut\'s view of spaceflight.

Right now you're hurtling around the Sun at a hundred thousand kilometres an hour. Join Kate Humble and Dr Helen Czerski as they explore the relationship between the Earth's orbit and the weather

Right now you're hurtling around the sun at 64,000 miles an hour (100,000 kms an hour). In the next year you'll travel 584 million miles, to end up back where you started. Presenters Kate Humble and Dr Helen Czerski follow the Earth's voyage around the sun for one complete orbit, to witness the astonishing consequences this journey has for us all. In this first episode they travel from July to the December solstice, experiencing spectacular weather and the largest tides on Earth. To show how the Earth's orbit affects our lives, Helen jumps out of an aeroplane and Kate briefly becomes the fastest driver on Earth.

In this final episode we complete our journey, travelling back from the March equinox to the end of June. Kate Humble is in the Arctic at a place where spring arrives with a bang, whilst Helen Czerski chases a tornado to show how the earth's angle of tilt creates the most extreme weather on earth.

In this second episode we travel from January to the March equinox. Kate Humble gets closer to the Sun than she has ever been before, whilst Helen Czerski visits a place that gets some of the biggest and fastest snowstorms on Earth.

This episode looks at the influence of the sun and reveals how its seasonal journey affects the lives of all creatures.

Film telling the story of the greatest physicists of the 20th century and the discoveries they made, told in their own words. Men and women who transformed our understanding of the universe, from unlocking the secrets of the atom to solving the mysteries of the cosmos.

This is the epic story of the stars, and how discovering their tale has transformed our own understanding of the universe.

In the last month of the space shuttle programme, Kevin Fong is granted extraordinary access to the astronauts and ground crew as they prepare for their final mission.

Professor Hawking considers one of the most important mysteries facing humankind: the possibility of intelligent alien life.

A new age of space exploration, and exploitation, is dawning. But surprisingly, some of the boldest efforts at putting humans into space are now those of private companies started by a handful of maverick billionaire businessmen.

Series in which mathematician Marcus du Sautoy explores the stories behind some of the most familiar scientific diagrams

When Polish priest and astronomer Nicolaus Copernicus developed his extraordinary theory of a sun-centred universe 500 years ago, he was flying in the face of both science and religion. Mankind had believed for thousands of years that the earth was at the centre of the cosmos, and to disagree was to risk derision and accusations of heresy.

Prof Jim Al-Khalili tackles the biggest subject of all, the universe, through a series of critical observations and experiments that revolutionised our understanding of our world.

In this second part, Professor Jim Al-Khalili carries us into the distant future to try to discover how the universe will end - with a bang or a whimper?

The hunt for aliens is on! After a distinguished career in cosmology Professor Martin Rees, the astronomer royal, has taken up the search for extra-terrestrials. Looking for aliens is no longer science fiction - it is a question that's engaging some of the greatest minds in science.
