This Sunday, two talents who've spent their lives among the stars will join forces as Stewart star in an animated Cosmos segment. He'll be the voice of 19th century astronomer William Herschel, who explains to his young son about how time and gravity affect light — or, in layman's terms, SPACE GHOSTS.


The episode, which will air on Fox on March 30th at 9:00pm, is actually titled "A Sky Full of Ghosts," so you know Tyson is pretty pleased on this metaphor. Hmm... wait a second... Creationists believe God is a spirit who lives in the sky on a cloud... science clearly is cool with the existence of space ghosts... man. It really seems like these guys could find some common ground here!
