Carl Sagan's Cosmos: A Personal Voyage (1980) (trailer)

3

Astronomer Carl Sagan's landmark 13-part science series takes you on an awe-inspiring cosmic journey to the edge of the Universe and back aboard the spaceship of the imagination.

The series was written by Carl SaganAnn Druyan, and Steven Soter, with Sagan as presenter.

Topics covered include: the 15-billion year history of the Universe; the evolution of life on Earth and what forms life might take on other worlds; Johannes Kepler, the first modern astronomer; the hellish atmosphere of Venus and the threat of the Greenhouse Effect on Earth; the search for life on Mars; the 17th century exploration of the Earth; the Voyager missions to Jupiter and Saturn; the possibility of time travel; Einstein's theories; the life cycle of stars; determining the origin of the Universe; the brain and the evolution of intelligence; how we might communicate with alien civilisations; the continued survival of the human race versus the threat of nuclear destruction.

The series was first broadcast by the Public Broadcasting Service in 1980, and was the most widely watched series in the history of American public television until The Civil War (1990). As of 2009, it was still the most widely watched PBS series in the world. It won two Emmys and a Peabody Award, and has since been broadcast in more than 60 countries and seen by over 500 million people. A book was also published to accompany the series.

Cosmos: A Personal Voyage has been considered highly significant since its broadcast; David Itzkoff of The New York Times described it as "a watershed moment for science-themed television programming"

Films For Action is a library for people who want to change the world.

 

Our mission is to provide citizens with the knowledge and perspectives essential to creating a more beautiful, just, sustainable, and democratic society.

Films For Action was founded in 2006 by a few friends in Lawrence, Kansas, after realizing how essential healthy media is to a healthy democracy.

Over the last 15 years, we've reviewed and curated over 1,000 free documentaries and 4,000 short films, plus over 150 pay-per-view documentaries, spanning 34 topics related to changing the world.

During this time we've been able to reach tens of millions of people - not by owning a TV network or spending truckloads of cash on advertising, but because millions of awesome people keep sharing 'films for action' with their friends on social media - in particular, our 850,000 supporters on Facebook and 70,000 site members. 

One of the coolest things is, thanks to our patrons, our library is ad-free and 100% supported by member donations. The Pay-Per-View films on our site, of course, help support the filmmakers, and 90-100% of the revenue for PPV films hosted by us goes to the filmmakers. 

To thank our $5/mo patron subscribers, we partner with filmmakers to provide access to a growing number of films that are unavailable for free. With just 29 highly-curated films at the moment, it's basically a mini "Netflix for world changers," but its main function is to support the library as a whole, which is 99% free and always will be.

Want to become a patron? Subscribe here. You can cancel or pause your subscription at any time.

If you'd like to know more, want to help out, or you're a filmmaker or distributor looking to collaborate, drop us a line via our contact page. 

You're also welcome and encouraged to submit videos directly to our library. Just click +Add Video at the top of the site and paste the video URL to get started. We share our favorite submissions with our fans on social media and feature them more prominently on the site.
