Discovering Astronomy is a college-level introductory astronomy textbook now in its sixth edition. The new edition by S. Shawl, G. Byrd, S Deustua, and M. Lopresto expands upon the previous edition's unique pedagogical features including an emphasis on understanding the nature of science, its use of in-text inquiries, and chapter discoveries. Chapter summaries help to emphasize the nature of science by grouping the chapter's ideas into observations, theory, and conclusions.

New to this edition are Critical Observations, which illustrate specific examples throughout astronomy of how a specific observation allowed astronomers to choose one theory over the competing ideas.

For the first time in a digital format, WebAssign has integrated the test bank questions associated with the textbook, which were collaboratively written by the authors of Discovering Astronomy. These questions can be used for practice, homework, or testing.

The eBook for this course is currently available directly from Acadiem.
