With this newly revised tenth edition of FOUNDATIONS OF ASTRONOMY, International Edition, author Mike Seeds' goal is to help you use astronomy to understand science--and use science to understand what we are. Fascinating and engaging, this text will help you answer two fundamental questions: What are we? How do we know? This edition addresses the newest developments and latest discoveries in the exciting study of astronomy, including new data on Jupiter's ring system; new observations of the shapes of stars; new evidence of dark energy, quasars, and galaxy collisions; and a look inside supernova explosions.
