Our accidental universe

The BBC presenter of 'Sky at Night', and Gresham Professor of Astronomy, Chris Lintott, takes us on an astonishing tour of bizarre accidents, big characters, and human error to tell the story of some of the most important astronomical events of the past hundred years.

As new telescopes are built on mountaintops and in deserts around the world, aiming to transform our view of the universe once more, Chris Lintott shows us that keeping an open mind will benefit us all - whatever might still be out there for us to find.
