With the Eighth Edition of Astronomy: A Beginner’s Guide, trusted authors Eric Chaisson and Steve McMillan bring a renewed freshness and analysis to recent changes in our understanding of the cosmos. As with the other two books in their Astronomy suite (one for two-semester courses and the other, a brief visual book), the authors continue to emphasize three major themes: the process of science, the size and scale of the universe, and the evolution of the cosmos.
