On a bright, cold morning on 15th February 2013, a meteorite ripped across the skies above the Ural mountains in Russia, distintegrating into three pieces and exploding with the force of 20 Hiroshimas. It was a stark reminder that the Earth's journey through space is fraught with danger. A day later, another much larger 143,000 tonne asteroid passed within just 17,000 miles of the Earth. 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.

Lost Horizons - The Big Bang

To coincide with the switch-on of the Large Hadron Collider, the world's largest particle accelerator complex, Professor Jim Al Khalili from the University of Surrey 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 remarkable idea that our universe simply began from nothing has not always been accepted with the conviction it is today and, from fiercely disputed leftfield beginnings, took the best part of the 20th century to emerge as the triumphant explanation of how the universe began. Using curious horn-shaped antennas, U-2 spy planes, satellites and particle accelerators, scientists have slowly pieced together the cosmological jigsaw, and this documentary charts the overwhelming evidence for a universe created by a Big Bang. Professor Al-Khalili comments: "This one-off documentary was made by the BBC Horizon team and was great fun to be involved with. The archive footage is fantastic too."

Across the Universe: The Voyager Show

A spectacular journey into the depths of space: In August 1977, NASA launches one of its most daring missions in space flights. The Deep Space orbiters Voyager 1 and Voyager 2 are shot into space. The task of the two orbiters: exploring the outer gas planets in our solar system. More than 30 years later, the two orbiters have traveled a distance of 15 billion miles and still send unique data to Earth. Countless recordings of these orbiters still serve as the only footage of the two planets Uranus and Neptune, and their moons. After more than 30 years of flight Voyager 1 is the farthest from Earth object that mankind has ever created. THE VOYAGER SHOW: ACROSS THE UNIVERSE demonstrates all the technical, historical and astronomical details of the fascinating Voyager missions that continue to this day.
