I have always lived in moderate to large sized cities, so imagine my surprise when my husband told me that the Andromeda Galaxy is bigger than the moon (see here for a picture that illustrates it). Now I know that placed side-by-side, a galaxy is bigger than the moon, but I thought that all galaxies look like little blurry stars and of course the moon is the largest object in the sky. This is true, if you live in a city or suburb. In a dark sky, like in the mountains or the country, Andromeda is bigger than the moon, but it is dimmer so that city lights wash it out to a barely identifiable smear. I felt slightly cheated. Next time I go out away from the city lights, I am definitely going to look up.
