Life is created in unimaginably large explosions called supernovas, scattering the elements formed in the heart of stars. What can they teach us about our origins?

Brilliantly narrated by film and television legend Sir Patrick Stewart, Journey To Space gives a sweeping overview of humanity’s accomplishments in space, as well as our ongoing activities and future plans. Journey To Space puts into historical context the magnificent contributions made by the Space Shuttle program and its intrepid space pioneers. It uses the most spectacular space footage – including unique views of Earth and operations in space – such as deploying and repairing the Hubble Space Telescope. It then goes on to show how the shuttle launched and assembled the International Space Station (ISS). Together, these programs have taught us how to live, build and conduct scientific experiments in space. The ISS will continue operating in space until 2024, and the film shows how it is building a foundation for the next giant leaps into space, concluding with a fascinating, realistic scenario of how astronauts will actually get to Mars, live there for long durations, and then return home after a two-and-a-half-year mission.

Thanks to observations of galaxy redshifts, we can tell that the universe is EXPANDING! Knowing that the universe is expanding and how quickly its expanding also allows us to run the clock backwards 14 billion years to the way the universe began - with a bang.

With his trademark wit, Richard Hammond takes on the ultimate engineering project: how on earth do you build a planet that is just right for life? What do you need to build a planet like ours, and what happens if you get anything wrong? With eye-popping graphics, Richard Hammond opens up a cosmic toolbox to work it out. He's going to build the whole thing, piece by piece, from the top of a two-mile high tower in the Californian desert.

Venus is a gorgeous naked-eye planet, hanging like a diamond in the twilight -- but it’s beauty is best looked at from afar. Even though Mercury is closer to the sun, Venus is the hottest planet in the solar system, due to a runaway greenhouse effect, and has the most volcanic activity in the solar system. Its north and south poles were flipped, causing it to rotate backwards and making for very strange days on this beautiful but inhospitable world.
