science ๐ญ Massive stars might explain weird galaxies found by Webb
Astronomers are investigating if early galaxies look strange because their biggest stars evolved differently. A new survey, TEMPOS, using Hubble's COS, is examining these stars in nearby dwarf galaxies. This work was published on September 21, 2026, and involves 29 massive stars from six local dwarf galaxies. These stars act as stand-ins to model conditions from the early universe, which Webb is currently exploring. Findings suggest wind speeds drop sharply at very low metallicity, potentially changing galaxy evolution. ๐
