Carl Sagan leads us on a guided tour of the universe, bringing such topics as Einstein's theory of relativity to a layman's level of understanding.

Award-winning series from 1980, which inspired a generation of scientists, Brian Cox amongst them.

Astronomer Carl Sagan leads us on an engaging guided tour of the universe, bringing such topics as Einstein's theory of relativity and Darwin's theory of evolution down to a layman's level of understanding. The first episode opens with a description of the cosmos and introduces the iconic 'Spaceship of the Imagination'. What, in 1980, were groundbreaking special effects allow Sagan to seemingly walk through environments that were actually models rather than full-sized sets.

The series is still regarded as a watershed moment for science-themed television programming.
