With this newly revised Twelfth Edition of FOUNDATIONS OF ASTRONOMY, the authors' goals are to help you use astronomy to understand science--and use science to understand what we are. Fascinating, engaging, and visually vibrant, this text will help you answer two fundamental questions: What are we? And how do we know?

Additional Product Information

Features and Benefits

  • For the Twelfth Edition, several elements have been designed to help students develop a stronger understanding of the big picture. Chapter-opening "Guideposts" connect previous and subsequent chapters to the material students are about to read, highlighting the "essential questions" within the current chapter. These essential questions act as the organizing elements in chapter summaries to encourage students to gain a deeper understanding of the material rather than just memorize a list of facts.
  • The authors' thematic emphasis on the scientific method is emphasized throughout. "How Do We Know?" boxes highlight great moments in science from various disciplines to illustrate the logical processes scientists use to learn about nature. End-of-section "Scientific Argument" features offer a carefully designed question to help students review key concepts. The short answers that follow emphasize how scientists construct logical arguments from observations, evidence, theories, and natural laws. An additional question gives students a chance to construct their own argument on a related issue.
  • A unique art program showcases this visual science in a consistent, striking new style. The hallmark Concept Art Spreads are numbered and emphasized in text narratives, making these two-page visual summaries easy to analyze and synthesize. Concept Figures combine art and text, encouraging students to synthesize information as a unified concept. Guided Discovery Figures provide insightful comments as they lead students through several frames of art, demonstrating processes that occur over time. All H-R diagrams are consistently designed to help students understand the main idea at a glance.
  • In addition, chapter content comes to life with many new and captivating photographs from the Spitzer Infrared Observatory, the Chandra X-Ray Observatory, and the Hubble Space Telescope, as well as new images of Saturn, its rings, and its moons from the Cassini spacecraft.
  • Enhanced WebAssign for Seeds' FOUNDATIONS OF ASTRONOMY, 12th Edition - Exclusively from Cengage Learning, Enhanced WebAssign® combines the exceptional Astronomy content that you know and love with the most powerful online homework solution, WebAssign. Enhanced WebAssign engages students with immediate feedback, rich tutorial content and interactive eBooks helping students to develop a deeper conceptual understanding of their subject matter. Online assignments can be built by selecting from hundreds of text-specific problems or supplemented with problems from any Cengage Learning textbook.
  • The Cengage YouBook helps students go beyond just reading the textbook. Students can also highlight the text, add their own notes, and bookmark the text. Animations and videos play right on the page at the point of learning so that they're not speed bumps to reading but true enhancements.
  • TheSkyX Student Edition includes a CD-based planetarium software option that provides ultimate flexibility for designing your course. Topics include the different types of sky coordinates, motions of the Earth and planetary objects, naming conventions and locations of astronomical bodies, lunar phases, solar and lunar eclipses, and sidereal time.

  • The latest updates on Earth-based giant telescopes and giant radio telescopes.
  • NEW information emphasizing observations over the entire electromagnetic spectrum.
  • Reordered subsections on star formation that place structure first and energy generation last.
  • Clarified discussions of white dwarfs and supernovae, Revised coverage of neutron stars.
  • NEW insight on global warming and ozone depletion, NEW section on extremophiles.
  • Additionally, new "How Do We Know" text boxes were added with significant text updates based on external technical review. These boxes highlight great moments in science from various disciplines to illustrate the logical processes scientists use to learn about nature. At least one review question per chapter refers to each "How Do We Know?" discussion which provides students with a review and suggests ways in which instructors could test this material.
  • While all chapters have been updated to clarify language to better reflect professional usage and reorganized for better clarity, Chapters 4, 6, 8, 10, 11, 14, 15, 16, 17, 23, 24, and 25 have all undergone a major rewrite and reorganization.

Author Bio

Michael A. Seeds

Mike Seeds was a professor of physics and astronomy at Franklin and Marshall College in Lancaster, Pennsylvania, from 1970 until his retirement in 2001. In 1989 he received F&M College’s Lindback Award for Distinguished Teaching. Mike’s love for the history of astronomy led him to create upper-level courses on archaeoastronomy and on the Copernican Revolution (“Changing Concepts of the Universe”). His research interests focused on variable stars and automation of astronomical telescopes. Mike is coauthor with Dana Backman of Horizons: Exploring the Universe, 12th edition (2012); Universe: Solar Systems, Stars, and Galaxies, 7th edition (2012); Stars and Galaxies, 8th edition (2013); The Solar System, 8th edition (2013); and ASTRO, 2nd edition (2013), all published by Cengage. He was senior consultant for creation of the 20-episode telecourse accompanying his book Horizons: Exploring the Universe.

Dana Backman

Dana Backman taught in the physics and astronomy department at Franklin and Marshall College in Lancaster, Pennsylvania, from 1991 until 2003. He invented and taught a course titled “Life in the Universe” in F&M’s interdisciplinary Foundations program. Dana now teaches introductory Solar System astronomy at Santa Clara University and introductory astronomy, astrobiology, and cosmology courses in Stanford University’s Continuing Studies Program. His research interests focus on infrared observations of planet formation, models of debris disks around nearby stars, and evolution of the solar system’s Kuiper belt. Dana is employed by the SETI Institute in Mountain View, California, as director of education and public outreach for SOFIA (the Stratospheric Observatory for Infrared Astronomy) at NASA’s Ames Research Center. Dana is coauthor with Mike Seeds of Horizons: Exploring the Universe, 14th edition (2018); Universe: Solar Systems, Stars, and Galaxies, 7th edition (2012); Stars and Galaxies, 8th edition (2013); The Solar System, 8th edition (2013); and ASTRO, 2nd edition (2013), all published by Cengage.
