About this collection

Space documentaries take you from the surface of Mars to the edge of the observable universe, explaining the cosmos in a way that makes you follow the reasoning rather than simply marvel. This collection holds 760 free space and astronomy documentaries.

Explore black holes and relativity, the Big Bang and the birth of galaxies, the James Webb and Hubble telescopes, Mars rovers and the search for life beyond Earth. You will find films on the planets and moons of the solar system, exoplanets and the possibility of alien life, dark matter and the far future of the universe, several made by working physicists and science communicators.

For anyone who has looked up and wondered, this is a collection that pairs breathtaking imagery with real science about where we are, how it all began, and where it is heading.
