Ann Druyan, creative director of the NASA Voyager Interstellar Record Project, Carl Sagan’s widow, and now executive producer of "Cosmos: A SpaceTime Odyssey", talks about the golden records on board Voyager 1 and reflects on the news that it is now in interstellar space. The record project was intended to demonstrate the diversity of life and culture on Earth for future humans or any intelligent extraterrestrial life it may come into contact with. Plus, Neil deGrasse Tyson, astrophysicist with the American Museum of Natural History and author of the book The Pluto Files: The Rise and Fall of America’s Favorite Planet, joins the conversation to talk about the scientific development that Voyager represents. He’s the host of the new "Cosmos" series.
For the past decade or so, scientists have been waiting for the Voyager 1 spacecraft to cross into deep space. New research suggests it already has â over a year ago.
