FOUNDATIONS OF ASTRONOMY, 11e, INTERNATIONAL EDITION brings science to life. With this newly revised Eleventh Edition of FOUNDATIONS OF ASTRONOMY, INTERNATIONAL EDITION, best-selling authors Mike Seeds and Dana Backman strive to help students use astronomy to understand science--and use science to understand what we are. Fascinating, engaging, and extremely visual, this text emphasizes the scientific method throughout as it guides students to answer two fundamental questions: What are we? And how do we know? In discussing the interplay between evidence and hypothesis, the authors provide not only fact but also a conceptual framework for understanding the logic of science. The Eleventh Edition addresses the newest developments and latest discoveries in the exciting study of astronomy, including information to emphasize observations over the entire electromagnetic spectrum; new data on star formation and stellar structure; new insight on global warming and ozone depletion; updated information on the Kuiper belt and dwarf planets; and more.
