Many of us spend more time at our desks than anywhere else. Astrophysicist Neil deGrasse Tyson takes us into his office at the Hayden Planetarium in New York City for a tour of his office, in the fourth of Science Friday's Desktop Diaries series. From a Saturn lamp Tyson made as a kid to his van Gogh pillow, Tyson has a lot of universe-themed paraphernalia. Tyson highlights some of his collection, and talks about what his journey to science stardom has been like.
