Stewart, who portrayed Captain Jean-Luc Picard on "Star Trek: The Next Generation," is one of two guest actors on the fourth episode of "Cosmos: A Spacetime Odyssey" hosted by astrophysicist Neil deGrasse Tyson. In the episode, dubbed "A Sky Full of Ghosts," Stewart will voice an animated version of astronomer William Herschel as part of a historical reenactment on the science-themed show.
Another British acting veteran, Julian Ovenden (Charles Blake on "Downton Abbey"), will make an appearance on Sunday's "Cosmos" as Michael Faraday, the 19th century inventor of the electric motor. In "A Sky Full of Ghosts," "Cosmos" will recount how Faraday "discovered invisible fields of force that help him understand how gravity works," according to an episode description.
Tyson took direct aim at Young Earthers, showing how if the universe was only 6,500 years old, we would only be able to see a small fraction of the stars in the Milky Way (those within 6,500 light years).
"To believe in a universe as young as six or seven thousand years old is to extinguish the light from most of the galaxy"
