The view this evening (Glenn)

(No, actually---not the view this evening. This is a sky picture showing how the Andromeda Galaxy, the nearest galaxy outside the Milky Way, would appear to our eyes if it were bright enough. It's roughly 1 million light years away and ca. 100,000 light years across, almost twice as large as the Milky Way, our own galaxy.)
