Cosmos: A Spacetime Odyssey is an American science documentary television series. The show is a follow-up to the 1980 television series Cosmos: A Personal Voyage, which was presented by Carl Sagan on the Public Broadcasting Station and considered a milestone for scientific documentaries. This series was developed to bring back the foundation of science to network television at the height of other scientific-based television series and films. The show is presented by astrophysicist Neil deGrasse Tyson, who was inspired by Sagan as a young college student. Among the executive producers are Seth MacFarlane, whose clout and financial investment was instrumental in bringing the show to broadcast television, and Ann Druyan, Sagan's widow and a co-creator of the original series. The series loosely follows the same thirteen-episode format and storytelling approach that the original Cosmos used, including elements such as the "Ship of the Imagination", but features updated information since the 1980 series and extensive computer-generated graphics and animation footage to augment the narration. The show is produced by Brannon Braga, and Alan Silvestri provides the backing score.
