About This Episode

Discoveries have gone wild in this StarTalk All-Stars mashup as we explore great discoveries, old and new, from nuclear weapons to TRAPPIST-1. First, you’ll hear host and astrophysicist Janna Levin and comic co-host Matt Kirshen talk with Rainer Weiss, co-founder of LIGO, on the recent breakthrough discovery of gravitational waves: why the discovery was so important, how Rainer found out about the discovery on vacation, and the significance of Einstein’s early predictions of gravitational waves. Next, join Bill Nye and Chuck Nice as they discuss nuclear weapons, key inventions we need for manned-missions to Mars, GMOs, GORE-TEX and more. Following that, host and astrophysicist Emily Rice and Chuck Nice sit down with astrophysicist David Kipping to explore the TRAPPIST-1 system: how we found it and if its possibly tidally-locked exoplanets are suitable for life. Finally, Carolyn Porco – Madam Saturn herself – is joined by Chuck Nice and astrobiologist Chris McKay to investigate what we’re learning about Enceladus, including the possibilities it harbors life and its collection of erupting geysers.
