Exciting Developments in Cosmology for 2025
The year 2025 is poised to unveil significant advancements in cosmology, centering around a variety of intriguing research projects. A particular focus is on new measurements of the Hubble constant from the James Webb Space Telescope (JWST) through the TRGB-SBF project, which seeks to refine distance measurements by utilizing the luminosity of red giants as standard candles. This independent effort aims to verify the existing expansion rate, potentially affirming the higher Hubble constant values previously reported. Such results could be announced as early as January 2025, sparking valuable discussions in the cosmological community.
