Based on the 6-part video series, Tyson explores all the stuff we know nothing about in the universe and how everything we do know – from the behavior of quarks to the birth of entire galaxies – has stemmed from scientists who’ve been willing to ponder the unanswerable.

Currently the head of NYC’s Hayden Planetarium, Tyson will fill you with wonder (and laughter) with his unique insights into space and science. Have a question about how the world works? He just might answer it in our interactive Q&A session.

A New York Times best-selling author, Tyson hosts the Emmy-nominated series StarTalk and will return as host of Cosmos: Possible Worlds premiering on National Geographic Channel March 9, 2020.
