Overview
Seeds/Backman/Wegryn’s “Foundations of Astronomy,” 15th Edition, offers a comprehensive and visually rich exploration of two key questions: "What are we?" and "How do we know?" Students gain a deep understanding of their place in the universe, viewed as a natural outcome of galaxy, star and planet formation. The stars-first approach provides clarity for studying planets in our solar system, including Earth, within the context of the universe's history and evolution. The authors emphasize the relationship between evidence and hypothesis, offering insights and understanding of scientific processes. Mathematical concepts are integrated into the text, avoiding separate sidebars. End-of-chapter "Sense of Proportion" questions encourage grasping relative time and size scales. Updates include a new chapter on exoplanets and the latest online resources to help meet students' needs.
- Chapter 25 is a new chapter focused exclusively on the rapidly expanding field of extrasolar planets, consolidating substantial up-to-date content with some material appearing in other chapters in the previous edition.
- Every chapter has been reviewed, revised and updated with recent discoveries and images, including the latest results from the James Webb Space Telescope and new international planetary missions. This includes the chapter-opening images.
- Revised and enhanced inclusive language, including using “we” terminology over “you.” The wording has also been updated to avoid excluding persons with low visual acuity.
- Concept Art Spreads are special two-page spreads that help students synthesize and visualize key scientific concepts.
- How Do We Know? Commentaries are integrated sections in every chapter that explain how scientific knowledge is built, emphasizing the role of evidence.
- What Are We? Essays are end-of-chapter essays that explore humanity's place in the cosmos, encouraging reflection of the larger picture.
- End-of-Chapter Active Learning Questions are designed to push students beyond the text, encouraging creative and critical thinking.
- WebAssign Integration offers practice opportunities, additional resources and real-time feedback to enhance learning, including new Stellarium Activities.
- How Do We Know? commentaries appear in every chapter and will help students comprehend how science works. They point out where scientists use statistical evidence, why they think with analogies, and how they build confidence in hypotheses.
- Practicing Science boxes at the end of many text sections are carefully designed to help students review and synthesize concepts from the section and practice thinking like a scientist.
- Special two-page Concept Art spreads provide an opportunity for students to synthesize their own understanding and share in the satisfaction that scientists feel as they uncover the secrets of nature.
- Celestial Profiles of objects in our Solar System directly compare and contrast planets with each other. This is the way planetary scientists understand the planets: not as isolated, unrelated bodies but as siblings with noticeable differences and yet many characteristics and a family history in common.
- Guideposts on the opening page of each chapter help students understand the organization of the book by focusing on a small number of questions to be answered as they read the chapter.
- End-of-Chapter Review Questions are designed to help students review and test their understanding of the material.
- End-of-Chapter Active Learning Questions go beyond the text and invite students to think critically and creatively about scientific questions. These questions can be pondered solo or discussed in class.
- End-of Chapter Sense of Proportion Questions gauge student understanding of relative sizes and timescales in the Universe.
- End-of-Chapter Learning to Look Questions prompt students to answer questions based on observations of visual evidence shown in diagrams or photographs.
