Cosmos: A Spacetime Odyssey is a American science documentary television series. 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, as a young high school student, was inspired by Sagan. Among the executive producers are Seth MacFarlane , whose financial investment was instrumental in bringing the show to broadcast television, and Ann Druyan , a co-author and co-creator of the original television series and Sagan's wife. 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" and the " Cosmic Calendar ", but features information updated since the series, along with extensive computer-generated graphics and animation footage augmenting the narration.

Episode 13 - Unafraid of the Dark. Tyson begins the episode by noting how the destruction of the Library of Alexandria lost much of humanity's knowledge to that point. He then contrasts on the strive for humanity to continue to discover new facts about the universe and the need to not close off further discovery. Tyson then proceeds to describe the discovery of cosmic rays by Victor Hess through high-altitude balloon trips, where radiation increased the farther one was from the surface. Swiss Astronomer Fritz Zwicky, in studying supernovae, postulated that these cosmic rays originated from these events instead of electromagnetic radiation. Zwicky would continue to study supernovae, and by looking at standard candles that they emitted, estimated the movement of the galaxies in the universe. His calculations suggested that there must be more mass in the universe than those apparent in the observable galaxies, and called this dark matter.

The new version features an upgrade of the Cosmic Calendar, and is co-produced by Ann Druyan, Sagan's widow. The first season concludes with a profile of Swiss astronomer Fritz Zwicky , a pioneer in the study of supernovas, neutron stars and dark matter in the universe; and a rumination on Carl Sagan's best seller "Pale Blue Dot.
