The Mira Distance Scale with HST and JWST: Measuring the Hubble Constant

Learn about groundbreaking research in cosmic distance measurements through this astronomy talk exploring the Hubble Constant tension and alternative measurement methods using Mira variables. Delve into the significant 5σ discrepancy between observed and predicted universal expansion rates, which hints at physics beyond the Standard Model of Cosmology. Discover how Mira variables - evolved asymptotic giant branch stars - serve as precision distance indicators and calibrators for Type Ia supernovae, offering advantages over traditional Cepheid or Red Giant Branch methods. Examine recent observations from both the Hubble Space Telescope and James Webb Space Telescope of Mira variables in M101, investigating their potential to resolve one of modern cosmology's most intriguing puzzles.
