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

Updated documentary series using computer animations, archive footage and interviews to examine our current knowledge and contact with the bodies of our solar system.

Professor Brian Cox explores the dramatic lives of the eight majestic planets/worlds that make up our solar system.

The rocky planets Mercury, Venus, Earth, and Mars were born at the same time from the same material - yet have lived radically different lives. What immense forces are at play?

Documentary series tracing our exploration of the solar system. This programme investigates geological activity, looking at the discovery of frozen lava plains on Venus, and a volcano on Mars that would dwarf Mount Everest. Scientists postulated that despite these intriguing surface features, the planets were effectively dead. However, pictures from the moons of Jupiter and Neptune would soon contradict this theory.

Documentary series tracing our exploration of the solar system. This programme looks at Voyager's expedition to the vast gas planets of Jupiter, Saturn, Uranus and Neptune.

Documentary series tracing the exploration of our solar system. This programme investigates our growing understanding of the origins of the moon.

Documentary series tracing the exploration of our solar system. A look at the quest to understand the sun, from the simple etchings of the astronomer Galileo to the discoveries of the latest solar probes. The latest scientific images reveal that the sun is a gigantic nuclear generator, a swirling mass of superheated gases that travel along powerful magnetic field lines.

This programme describes the investigation of weather systems found throughout the solar system. Scientists have discovered sulphuric acid rain and metallic snow on Venus, while space probes have revealed the arid surface and frozen seas of Mars and the mysteries of the gas giant, Saturn.

The documentary series about the solar system examines how our understanding of the evolution of life on earth has changed, and explores the evidence for life on other planets. In 1976, two robotic probes suggested that the surface of Mars was dead. But the latest research reveals that this may not be the case and that it is possible that life on earth may have evolved from Mars.

Documentary series tracing the exploration of our solar system. This programme looks at the fate of the solar system and explores the new planetary systems that are being found around nearby stars.

In the final episode, Professor Brian Cox journeys to the remotest part of the solar system, a place that the most mysterious planets call home.

Professor Brian Cox reveals the history of Saturn. Saturn began life as a strange planet of rock and ice and in time transformed into a gas giant, ring-less and similar looking to its rival, Jupiter.

Brian Cox continues his exploration of the solar system with a visit to a planet that dwarfs all the others: Jupiter. Its size gives it a great power that it has used to manipulate the other planets.

Professor Brian Cox continues his tour of the solar system revealing that it was once home to not one, but two blue planets.

Drawing on the latest theories as well as 200 years of scientific discoveries and the genius of Einstein, Brian tries to answer the classic questions raised by the Doctor - can you really travel in time? Does extra-terrestrial life exist in our galaxy? And how do you build something as fantastical as the TARDIS?

For many years our place in the universe was the subject of theologians and philosophers, not scientists, but in 1960 one man changed all that.

It's the start of a new solar cycle, and the spacecraft Ulysses faces retirement, but solar missions Stereo and SOHO are still revealing our nearest star in a new light

Michael Mosley embarks on an informative and ambitious journey exploring how the evolution of scientific understanding is intimately interwoven with society's historical path.

This is the story of the most extraordinary journey in human exploration, the Voyager space mission. In 1977 two unmanned spacecraft were launched by NASA, heading for distant worlds. It would be the first time any man-made object would ever visit the farthest planets of the solar system - Jupiter, Saturn, Neptune and Uranus.

Professor Brian Cox explores the globe to reveal how a few fundamental laws of science gave birth to the most complex and unique feature of the universe - life.

In this episode Brian Cox visits South East Asia's 'Ring of Fire'. In the world's most volcanic region he explores the thin line that separates the living from the dead and poses that most enduring of questions: what is life?

The universe is almost entirely devoid of life. Earth, the planet we call home, seems to defy the laws of physics. It is teeming with life in all colours, shapes and sizes. No-one knows for sure how many different species are alive right now, our best guess is close to 8.7 million

Professor Brian Cox reveals how the fundamental scientific principles and laws explain not only the story of the universe but also answer mankind's greatest questions.

Professor Brian Cox seeks to understand the nature of time.
