“After ten days, we’ve come thirty million light-years from Sol. Spinner, we’ve reached the center of the Virgo Cluster—the supercluster of galaxies of which our Galaxy is a member. Way behind you is a little patch of light: that’s the Local Group—three million light-years across, the small cluster dominated by our Galaxy and the Andromeda galaxy. And to your left, at about eleven o’clock, you’ll see the center of the Virgo Cluster itself: that massive group of several thousand bright galaxies. They used to be bright, anyway...”
