Plot Synopsis

COSMOS: POSSIBLE WORLDS, which is sometimes called the third season of COSMOS, is a one-hour documentary series that features time travel to past eras, revealing unsung scientific heroes who sacrificed everything in the pursuit of scientific revelation. It transports the viewer to a hidden place where life may have begun on Earth, to some of the lost worlds of our ancestors and to the possible worlds of our remote descendants. Astrophysicist Neil deGrasse Tyson of the American Museum of Natural History reprises his role as host and executive science editor, which he started in COSMOS: A SPACETIME ODYSSEY, the followup to the classic COSMOS series that debuted on PBS in 1980. Filmed across 19 locations in 11 countries, the creative corps of craftspeople include Emmy-nominated cinematographer Karl Walter Lindenlaub; Academy Award-winning and Emmy-nominated costume designer Ruth E. Carter; Emmy-winning and Academy Award-nominated composer Alan Silvestri; VFX supervisor Jeff Okun; and supervising animation directors Lucas Gray; Emmy-nominated Brent Woods; and Academy Award-nominated Duke Johnson.

"COSMOS: POSSIBLE WORLDS continues the eternal search for answers about ourselves in the universe," Tyson says. "The series explores the interwoven tapestry that is life on Earth and calls on us to remember this truth as we collectively build the future of civilization."

"The importance of our species' continued investment in the enterprise of science cannot be overstated. As we strive toward a deeper understanding of the universe around us, I am honored to play a small role in the elevation of that passion, as a part of the COSMOS producing team," says executive producer Seth MacFarlane, who also voices President Truman in the series.

COSMOS: POSSIBLE WORLDS airs from 8-10 PM ET for seven weeks beginning March 9, in the US, and it will air globally in 171 countries and 43 languages and on FOX in summer 2020.
