Probing binary stars in the Small Magellanic Cloud with the JWST‎

The formation and evolution of individual stars in a galaxy shape the evolution of the galaxy itself. Stars and stellar remnants make up the vast majority of a galaxy's mass, so it's not surprising that the stellar population affects the evolution of galaxies. In the Milky Way's disk and bulge, stars and dead stars make up about 85% of the baryonic mass.
