WebIn a disk galaxy, the disk stars all orbit in the same direction; each star’s velocity is determined by the total mass interior to its orbit. In M31 we hoped to detect the Hα spectral line emitted by hydrogen gas clouds that had been ionized by nearby hot stars. WebThe images and illustration reveal that the Andromeda Galaxy's (M31's) core is composed of a ring of old, red stars and a newly discovered disk of young, blue stars. The disk is trapped within a supermassive black hole's gravitational field. The mass of Andromeda's monster black hole is 140 million times greater than that of our Sun.
