A brief, introductory astronomy book designed for readers with little or no scientific background, A Beginner's Guide uses an exceptionally clear writing style. The authors present a broad view of astronomy without complex mathematics, yet the book discusses important concepts without simplification. The book's organization follows the popular and effective “Earth-Out” progression, starting with our planet and then moving through the solar system. A study of the Sun as a model star follows, then the book covers the Milky Way Galaxy, cosmology, and the universe as a whole. Because of its easy-to-read yet comprehensive coverage of astronomy, this book can serve as excellent reference material for those readers interested in learning about our universe.
