New Features

The addition of learning objectives to each chapter helps students understand the goals for the chapter.

Carefully updated art that includes the latest images and scientific results from planetary spacecraft and space telescopes, including Hubble and Kepler. These updates not only add to the book's visual appeal but enhance student learning with clear, accurate representations that reflect the most current data in the field.

New and regenerated maps of the planets using a consistent equal-area map projection.

SmartBook is the first and only adaptive reading experience available for the higher education market. Powered by an intelligent diagnostic and adaptive engine, SmartBook facilitates the reading process by identifying what content a student knows and doesn't know through adaptive assessments. As the student reads, the reading material constantly adapts to ensure the student is focused on the content he or she needs the most to close any knowledge gaps.

Key Features

LearnSmart™ an intelligent learning system that uses a series of probing questions to pinpoint each student's knowledge gaps. LearnSmart strengthens student understanding and retention of your course's fundamental concepts; effectively preparing your students for class so you can review less and teach more. The LearnSmart methodology is simple: determine the concepts students don't know or understand, and then teach those concepts using personalized plans designed for each student's success.

"Key Points" are included at the end of each unit to reinforce student learning.

A total of 9 full page, "Looking Up" boxes are designed to show students how some of the astronomical objects discussed in the text connect with the real sky that they can see overhead at night. These full-page art pieces show where a variety of frequently mentioned and important astronomical objects can be seen. Each feature presents a photograph of one or more constellations in which nebulas, star clusters, and so forth are identified and illustrated.

Numbered marginal Conceptual Questions are included in the text and promote thinking and discussion.

The fourth edition includes the latest scientific information and photos. Information was updated throughout the book for clarity and to include some of the most interesting new images of astronomical events available. The author paged this material himself to keep the art and text together to allow for easy reference.

Pathways to Astronomy covers astronomy like a series of mini-lectures instead of a monograph of the entire field of astronomy. The same material covered in other introductory astronomy texts is included, but this is broken up into smaller self-contained units. These units are woven together to flow naturally for the person who wants to read the text like a book, but it is also possible to assign them in different orders, or skip certain units altogether.

Seasonal star charts (spring, summer, fall, winter) are included in the text.

Throughout the text unique symbols for each physical quantity are used consistently. Where tradition dictates that the same letter be used for different quantities (such as acceleration and semi-major axis), we have used distinctive fonts. A symbol glossary in the appendix helps students review the meaning of symbols in formulas.

This text includes a periodic table geared toward astronomy -- Cosmic Periodic Table.

Electronic Media Integration has been incorporated throughout the text. Icons have been placed in the margin to alert readers that animation and interactives can be found in Connect (text web site).

Thomas Arny

Tom Arny is an Emeritus professor in the Astronomy Department at the University of Massachusetts at Amherst. He was associated there with the Five College Astronomy Program(comprising faculty from U-Mass, Amhurst, Hampshire, Mt. Holyoke, and Smith Colleges). Dr. Arny received his undergraduate degree from Haverford College and his Ph.D. in astronomy from the University of Arizona. In addition to his interest in astronomy, he has a long-standing fascination with the natural world: weather (especially atmospheric optics such as rainbows), birds, wildflowers, and butterflies.
