This edition has been developed with the expert input of more than 150 introductory astronomy instructors nationwide. Discovering Astronomy addresses, in detail, the five concepts identified as most difficult for students to grasp:

• big bang cosmology
• stellar evolution
• gravity
• light and spectra
• mathematical concepts

The pedagogy strengthens critical reasoning and evaluation skills, leading to a clearer understanding of the process of science, and enhancing students' abilities to apply scientific concepts in new contexts.

The fifth edition includes recent results from the Mars orbiters and landers, and the Cassini mission to Saturn. Hubble Space Telescope results are discussed when appropriate. The discussion of extrasolar planets has been updated and expanded significantly.  

This text engages students in active involvement in their own learning process. One way the book achieves active involvement is through the inclusion of numerous "Inquiries" within the reading. These "Inquiries" purposely break up the reading so the student stops and thinks about what's been read before continuing. Answers to these "Inquiries" at the end of each chapter allow students to gauge their understanding.
