Push the limits of your imagination as astronomers attempt to grasp the mind-boggling extremes of size, distance and speed within our universe by bringing them down to earth. In this episode, our cast uses awesome analogies to bring the biggest objects, farthest distances and fastest speeds down to earth. To truly understand the scale of the cosmos, we jump behind the wheel of monster trucks, scale the Golden Gate Bridge, and race across the desert in a rocket-powered car.

To celebrate the 30th anniversary of its launch, this film tells the remarkable story of how the Hubble Space Telescope revealed the awe and wonder of our universe and how a team of daring astronauts risked their lives to keep it working.
Additionally, a team led by Greg Bacon and Dr Frank Summers has transformed many of Hubble's most awe-inspiring images into visualisations - from the spectacular Orion Nebula to the fabulous Whirlpool Galaxy and ethereal Horsehead Nebula. One of the most mind-blowing of the visualizations takes the viewer on a remarkable journey, flying across the Universe to witness almost 13 billion years of cosmic evolution. It's called the 'Hubble Ultra Deep Field' and was created when Hubble stared at a small patch of sky for the equivalent of more than 11 days to see some of the most distant galaxies ever observed.

Marcus du Sautoy uncovers the patterns that explain the shape of the world around us. Starting at the hexagonal columns of Northern Ireland's Giant's Causeway, he discovers the code underpinning the extraordinary order found in nature - from rock formations to honeycomb and from salt crystals to soap bubbles. Marcus also reveals the mysterious code that governs the apparent randomness of mountains, clouds and trees and explores how this not only could be the key to Jackson Pollock's success, but has also helped breathe life into hugely successful movie animations.

Take an exhilarating, unprecedented exploration of the seven most amazing wonders of our solar system. Our virtual tour begins with a trip to Enceladus, one of Saturn's outer moons, where icy geysers spout from its surface. Then venture to Saturn's famous rings, which contain mountain ranges that rival the Alps. Next dive into the eye of the biggest storm in the solar system--Jupiter's Great Red Spot. Soar through the Asteroid Belt, containing millions of leftover rocks from the formation of the solar system. Trek up Mount Olympus, the largest volcano, located on Mars. Have a close encounter with the searing surface of the Sun, and finish the journey by exploring our home planet Earth.

Annalisa Piras and former editor of The Economist Bill Emmott, which explores the crisis facing Europe. Through case studies of citizens in different countries, the film explores a range of factors that have led to the present crisis, economic and identity challenges across Europe. High-level experts analyse how and why things are going so wrong. The film includes fictional scenes, set in a post-EU future, which feature archaeologist Charles Granda (played by Angus Deayton) travelling on a flight through a menacing storm, explaining to a child passenger what the EU was. Sombre, thought-provoking and witty, the film frames Europe through the eyes of those who have most at stake - the Europeans themselves.

Just 92 elements made up the world, but the belief that were only four - earth, fire, air and water - persisted until the 19th Century. Professor Al-Khalili retraces the footsteps of the alchemists who first began to question the notion of the elements in their search for the secret of everlasting life.He reveals the red herrings and rivalries which dogged scientific progress, and explores how new approaches to splitting matter brought us both remarkable elements and the new science of chemistry.
