The James Webb Space Telescope (JWST) is a revolutionary space observatory that is revolutionizing our understanding of the universe. With its advanced infrared capabilities, JWST is able to observe some of the earliest galaxies that formed after the Big Bang, as well as study the atmospheres of exoplanets in search of potential signs of habitability.

The podcast episodes discuss the role of JWST in the search for habitable exoplanets and its observations of the cosmic dawn, when the first stars and galaxies began to form in the universe. Episode 46134 explores how JWST is being used to detect atmospheres around exoplanets, while Episode 38238 discusses the telescope's findings on some of the earliest galaxies that formed in the universe.
