"Groundbreaking Discovery: Tiny, Dormant Galaxy Unveiled"
Astronomers using the James Webb Space Telescope as part of the JADES survey have discovered a new quiescent galaxy, JADES-GS+53.12365-27.80454, which is the least massive quiescent galaxy detected at a high redshift. The galaxy has a stellar mass of only 950 million solar masses and has been quiescent for 600 million years. Its structure suggests a different evolutionary path compared to more massive galaxies at similar redshifts. The discovery provides evidence of environment-driven quenching and may improve our understanding of galaxy evolution. Further investigation using ground-based surveys and targeted surveys with JWST is recommended.
