In July 1969, history was made as 600 million people watched Neil Armstrong's giant leap for mankind on the surface of the moon. But behind these iconic images is an untold story. Now, 50 years later, Discovery and Science Channel celebrate the Apollo 11 moon landing with a two-hour television event, APOLLO: THE FORGOTTEN FILMS, that tells the complete story of this most audacious of missions. Featuring forgotten and never-before-seen footage from events surrounding the landmark mission, the documentary by Duncan Copp traces the decade's worth of effort involving half a million scientists that was required to enable that "one giant leap for mankind". The archives reveal the incredible lengths an army of engineers, scientists and astronauts went to, to achieve America's greatest technological feat.

It is one of the most baffling questions that scientists can ask: how big is the Universe that we live in? Horizon follows the cosmologists who are creating the most ambitious map in history - a map of everything in existence. And it is stranger than anyone had imagined - a Universe without end that stretches far beyond what the eye can ever see. And, if the latest research proves true, our Universe may just be the start of something even bigger. Much bigger.

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.

Today we’re talking about our galactic neighborhood: The Milky Way. It’s a disk galaxy, a collection of dust, gas, and hundreds of billions of stars, with the Sun located about halfway out from the center. The disk has grand spiral patterns in it, formed by the traffic jams of stars and nebulae, where stars are born. The central region is shaped like a bar, and is mostly old, red stars. There’s also a halo surrounding us of old stars.
