StarTalk
Famed astrophysicist Neil deGrasse Tyson demystifies the universe, from quasars to rock climbing, with comic co-hosts and expert guests.
This is a multi-format science show where Neil deGrasse Tyson acts as the central expert. Episodes are either two-hander explainers with comedian Chuck Nice or panel interviews with an expert guest, like a fellow scientist or a high-performer such as Alex Honnold. The show's core mission is to filter all of pop culture and human experience—from movies to sports—through the lens of scientific principles, making complex physics and astronomy accessible.
“Unlike drier academic podcasts, StarTalk intentionally pairs its lead astrophysicist with comedians, creating a dynamic where the co-host serves as an audience proxy, asking basic questions and providing comic relief. The show's unique hook is applying rigorous scientific scrutiny to pop culture phenomena.”

Notable episodes
- 01Overcoming Fear, with Alex Honnold
A classic StarTalk episode applying the principles of physics, physiology, and psychology to a world-class athlete's seemingly superhuman feat.
- 02Matt O’Dowd’s Favorite Object in the Universe
A deep dive into a complex astronomical topic (quasars) made accessible through Tyson's analogies and a guest expert from PBS Space Time.
- 03How Much Does Air Weigh?
A prime example of the show's non-interview format, where Tyson and co-host Chuck Nice use Socratic dialogue to explain a fundamental physics concept.
What you'll be asked on this show
Neil deGrasse Tyson's interview style is that of a Socratic educator. He often opens by establishing a baseline definition for the audience ("Could you explain what 'free solo' means?") before diving into the underlying science. He uses guests as a springboard to explore his own favorite topics—physics, evolution, and astronomy—often framing questions with historical context from his own career to show how science has advanced. He'll frequently summarize a guest's complex point with a pithy analogy ("Is it safe to say a quasar is a galaxy whose black hole is having dinner?") and uses his comic co-host, Chuck Nice, to voice the audience's potential confusion and keep the conversation grounded.
The format varies between guest interviews and "Cosmic Queries" episodes. Neil deGrasse Tyson is the central scientific authority, flanked by a comic co-host (usually Chuck Nice) who translates jargon and injects humor. The tone is educational but informal, with Tyson's signature sign-off being "Keep Looking Up."
