Britain's Star Men: Heroes of Astronomy

Four British astronomers celebrate 50 years of work and friendship by going on a road trip to revisit some of the world's greatest observatories. In California, a world leader in observational astronomy at a time when America's space programme was at its height, the astronomers spent their formative years developing friendships that would last a lifetime, and making scientific discoveries that would change the course of history. Together they represent the most productive period astronomy has ever had. Their journey through the southwestern United States allows them to see once again the places and landscape they explored as young men. Now in their seventies, they share their reflections on a life spent looking at the universe. Star Men celebrates the history of stargazing - the inventions and discoveries that have enabled us to learn so much about the universe, but more importantly to understand how much more we have yet to discover.
