Astronomy with the Naked Eye

Abstract

Today we explore the sky with powerful instruments and we know that there are millions of galaxies in the universe, each containing billions of stars. We are accustomed to thinking about the universe from an “unprivileged” point of view. We know, moreover, that the Sun is only one among billions of stars, and a pretty bog standard one at that, and that it occupies a relatively insignificant position in one of the branches—itself quite bog standard—of one of those galaxies: the Milky Way.
