Catching Andromeda`s Light
... The Earth moves fast around the Sun. But if the Sun had much more mass than it does, the Earth would move much faster. So the very high speed of the stars and gas near Andromeda’s center means there must be so much mass that it’s a black hole! Astronomers calculate that Andromeda’s central black hol ...
