Addressing the newest developments and latest discoveries in the exciting study of astronomy, this revised seventh edition of STARS AND GALAXIES helps students use astronomy to understand science and use science to understand what we are. Fascinating and engaging, STARS AND GALAXIES illustrates the scientific method and guides students to answer these fundamental questions: What are we? How do we know? In discussing the interplay between evidence and hypothesis, author Michael Seeds provides not only facts but also a conceptual framework for understanding the logic of science.
