This comprehensive textbook for the two-term course focuses students on not only the foundational concepts of astronomy but on the process of scientific discovery itself—how we know what we know about the cosmos. Engagingly written and filled helpful pedagogical tools, the book also excels at dispelling widely held misconceptions and helping students avoid common pitfalls as they explore the heavens.

Thoroughly updated, the new edition features the latest discoveries and new pedagogy, and is supported by an expanded media/supplements package centered on W. H. Freeman’s extraordinary new online course space, LaunchPad.
