Themes Peering into Space

Peering into Space

To gaze upward and know we're part of a vast system of heavenly bodies -- it is simultaneously humbling and utterly thrilling. TEDTalks collects some amazing thinking on our place in the universe. Carolyn Porco takes us on a thrilling flyby of Saturn and its moons, while Burt Rutan, Bill Stone and George Dyson talk about how we could start putting more humans up into orbit and beyond.

Sir Martin Rees and David Deutsch offer throughtful talks worth savoring, on our physical and metaphysical place in space.

And Steve Jurvetson shares the sheer glee of shooting off rockets into the near cosmos.
