This is a list of star-forming regions in the Milky Way Galaxy and the Local Group. Star formation occurs in molecular clouds, which become unstable to gravitational collapse, and these complexes may contain clusters of young stars and regions of ionized gas called H II regions. Stars typically form in groups of many stars, rather than in isolation.
