Hyperactive stars move at twice speed of sun Stars in a distant galaxy move at stunning speeds - greater than 1 million mph, astronomers say. These hyperactive stars move at about twice the speed of our sun through the Milky Way, because their host galaxy, 1255-0, is very massive, yet strangely comp...
