     Lower photo below, R136, a supercluster in the Tarantula Nebula, which is primarily responsible for lighting up the Nebula. R136 consists of dozens of supermassive (50 to 80 solar mass) extremely hot (spectral type O3) stars formed within the last million or two years and embedded within an extremely rich open cluster with perhaps half a million solar masses.
