SnagFilms.com now has this seminal body of work up on its site. I have enjoyed watching these episodes. I saw many of them as a young adult and was mesmerized.
Carl Sagan was “the man” and he made science cool and fun for a generation.
Watch this one. It is a famous episode on black holes and supernovas. The Lives of Stars. Click here and be enlightened.
Mr. X, Carl Sagan, is the man. Love his books, and his work. His life was cut far too short, but in his 64 years he provided plenty to talk about and celebrate. This coming from a penguins fan.
