The thirteen episodes of the second season of Cosmos (2014) aired on National Geographic earlier this year. Starting from the 22nd of September, the new season - called Cosmos: Possible Worlds - will also air on Fox. The season is presented by Neil deGrasse Tyson (starTalk with Neil deGrasse Tyson).
Even though this is the second season at Fox, this is technically the third season of the Cosmos documentary series. In 1980, Cosmos (1980) aired on PBS. This season was more commonly known as Cosmos: A Personal Voyage. Cosmos: A Spacetime Odyssey aired on Fox in 2014 and after six years the series returns with its second season subtitled Possible Worlds.
