The Scale Model of Our Solar System

With the December 2021 launch of the James Webb Space Telescope, one of the most expensive and ambitious scientific initiatives ever attempted commenced operations. Now that the telescope has been successfully deployed in its unique position in space, its advanced instruments will be able to gather data on questions that scientists once could only dream of answering. Is there life on other planets? How do supermassive black holes mold the mass in their galaxies? JWST may soon be able to tell us. In this episode, host Steven Strogatz speaks to two researchers leading JWST's observations of our universe: Marcia Rieke, the principal investigator of the telescope's Near-Infrared Camera, and Nikole Lewis, an astrophysicist studying planets outside of our solar system. (For more on the JWST and the history of its construction and launch, read Natalie Wolchover's article, "The Webb Space Telescope Will Rewrite Cosmic History. If It Works," which was recently honored with a 2022 Pulitzer Prize for Explanatory Reporting.)
