Cosmos: A Spacetime Odyssey returns to Fox on Sunday night with episode 4, titled “A Sky Full of Ghosts.”

Travel back in time to 1809, when astronomer William Herschel (guest voice Patrick Stewart, “Star Trek: The Next Generation”) observes how light plays tricks with time and gravity.

Later, Tyson embarks on an exhilarating journey to the event horizon of a black hole.

Season 1 is scheduled for 13 episodes.

The show airs at 9 p.m. ET.
