Abstract
UNLIKE the other nebulæ in the local group, the two companions of the Andromeda nebula—M 32 and NGC 205—and the central region of the Andromeda nebula itself, have hitherto defied resolution into stars by the most powerful instruments at the disposal of astronomers. It was therefore supposed that the luminosity of their brightest stars was abnormally low. This conclusion is amply confirmed by the resolution of these objects on plates taken recently on the 100-in. telescope (W. Baade, Astrophys. J., 100, 137; 1944).
