James Webb Space Telescope: How does it work?

The $10bn (£7bn) project, a collaboration between Nasa, the European Space Agency and the Canadian Space Agency, hopes to look further back in time than ever before - to find out more about the creation of the first stars and the beginnings of our Universe.
