Fascinating, engaging and extremely visual, Seeds/Backman/Wegryn's "Foundations of Astronomy," is renowned for its current coverage, reader-friendly presentation and detailed yet clear explanations. The authors' goals are to help you use astronomy to understand science, and use science to answer two fundamental questions: "What are we?" and "How do we know?" The text is available with WebAssign, the powerful digital solution that enriches the teaching and learning experience. It includes Stellarium Activities for every chapter through WebAssign, plus Virtual Astronomy Labs 3.0 -- a set of 20 interactive activities that combine analysis of real astronomical data with robust simulations -- providing a true online laboratory experience for your Introductory Astronomy course.
