The enhanced pedagogy, streamlined presentation, and integrated media of The Cosmic Perspective, Third Edition, makes it easier than ever for students to successfully navigate their way through introductory astronomy. Renowned for its up-to-date and expert coverage, this student-friendly text focuses on central ideas and unifying themes to provide a cosmic context. New chapter openers and end-of-chapter summaries expertly steer students through key concepts, helping them stay focused on core learning goals. The text's superior media package has been further enhanced to provide professors with superior in-class presentation tools and the ability to use and assign media activities out of class in creative ways they may not have previously considered. In particular, The Astronomy Place Website's highly acclaimed tutorials are now fully assignable with a built-in grading system, and a new Lecture Launcher CD-ROM puts a comprehensive library of in-class presentation applets, animations, and images in the palm of professors' hands. The Third Edition also features expanded coverage on seasons, the solar system, chronological history, and astrobiology. A reorganized table of contents makes the text even more cohesive and easy to use.
