Looking almost 11 billion years into the past, astronomers have measured the motions of stars for the first time in a very distant galaxy. They are whirling at a speed of one million miles per hour--about twice the speed of our Sun through the Milky Way. The galaxies are a fraction the size of our Milky Way, and so may have evolved over billions of years into the full-grown galaxies seen around us today.
