JWST Cycle 4 Spotlight, Part 4: Stellar Populations and the Interstellar Medium

Welcome back to our five-part examination of Webb's Cycle 4 General Observations program. In the first and second installments, we examined how some of Webb's 8,500 hours of prime observing time this cycle will be dedicated to exoplanet characterization, the study of galaxies at "Cosmic Dawn," and the period known as "Cosmic Noon." Today, we'll look at programs that will leverage Webb's unique abilities to study stellar populations and the interstellar medium in galaxies.
