TL;DR

New JWST study of nine early galaxies, combined with VLT data, reveals a larger population of faint, small stars than in the Milky Way. This means those galaxies contain more mass than previously estimated, with one example reaching up to four times the prior mass. The finding could require revisions to galaxy-formation models and suggests more planets may have formed around small stars in the early universe.
