Science writer Dr Gabrielle Walker has been obsessed with ice ever since she first set foot on Arctic sea ice. In this programme she searches out some of the secrets hidden deep within the ice crystal to try to discover how something so ephemeral has the

90 million miles away from us is the power that shapes our world - the sun. We see it shine in the sky above us, but beyond our sight something dramatic is happening - the sun is going into overdrive.

Documentary-maker David Malone delves into the secrets of ocean waves. In an elegant and original film he finds that waves are not made of water, that some waves travel sideways and that the sound of the ocean comes not from water but from bubbles.

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

Jim Al-Khalili investigates whether quantum physics might solve mysteries in biology.

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

Theoretical physicist and futurist Michio Kaku shows how quantum physics is giving mankind the almost godlike power to manipulate the fundamental building blocks of matter. Science fiction ideas like the space elevator, teleportation, invisibility cloaks, or nanosized molecular machines might soon become a reality. But will we use our unprecedented scientific mastery wisely?

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

In this episode, Brian travels around Australia to explore the physics of the size of life. Beginning with the largest organisms on our planet, a forest of giant eucalyptus trees, he then takes to the seas to get up-close with an ocean giant - the great white shark.

As far as we know, there is only one place in the universe on which life has taken hold - Earth - but for how much longer will this distinction remain? Astronomers are on the brink of finding other worlds the same size as Earth and the same distance from their star.

In this spellbinding series Professor Brian Cox visits the most extreme locations on Earth to explain how the laws of physics carved natural wonders across the solar system.

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.

What are we and where do we come from? Professor Brian Cox finds out.

Brian Cox takes on the story of the force that sculpts the entire universe - gravity.

In the last episode of Professor Brian Cox's epic journey across the universe, he travels from the fossils of the Burgess Shale to the sands of the oldest desert in the world to show how light holds the key to our understanding of the whole universe, including our own deepest origins.
