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.

Witness the evolution of galaxies; from clouds of cold gas floating in the voids of space 13 billion years ago, to the magnificent spirals that fill our night.

Finding alien life on a distant planet would be amazing news - or would it? If we are not the only intelligent life in the universe, this probably means our days are numbered and doom is certain.

Today we are talking about the life -- and death -- of stars. Low mass stars live a long time, fusing all their hydrogen into helium over a trillion years. More massive stars like the Sun live shorter lives. They fuse hydrogen into helium, and eventually helium into carbon (and also some oxygen and neon). When this happens they expand, get brighter, and cool off, becoming red giants. They lose most of their mass, exposing their cores, and then cool off over many billions of years.
