Katy Perry is all in with her inner nerd!
The 32-year-old singer is one of several celebrity guests on the fourth season of Neil deGrasse Tyson's geek-tastic science-driven talk show, StarTalk, and only ET has the exclusive trailer of the new episodes, which premiere in October on NatGeo.

Special comedian co-hosts this season include Scott Adsit, Godfrey, Sasheer Zamata and Maeve Higgins, while Tyson often calls upon Bill Nye to discuss the week's theme, while other celebs from the entertainment and science worlds, such as Adrian Grenier, join via live chat.
“Our aim with StarTalk is for the audience to not only be entertained, but also walk away with a deeper sense of how or why things work,” said Tyson in a statement. “We don’t want to just appeal to science fans, we want to connect with those who may not necessarily love the subject or realize how science touches their lives every day.”
StarTalk, which is recorded in front of a live studio audience at the American Museum of Natural History Museum in New York City, is based off Tyson's radio show and podcast of the same name. Earlier this month, it earned its third Emmy nomination for Outstanding Informational Series or Special.

Each episode features interviews with prominent names from pop culture, politics, sports and news, and focuses on how science and technology have affected their lives and careers. Past seasons have featured guests like Bill Clinton, Seth MacFarlane, Whoopi Goldberg and Buzz Aldrin.
