Stars and Galaxies

Stars and Galaxies, 10th Edition, is an astronomy textbook written by Michael A. Seeds and Dana Backman and published by Cengage Learning. The volume structures its coverage around the scientific method, guiding readers through two guiding questions: what we are and how we know.

The textbook presents astronomical principles by pairing factual information with a conceptual framework for scientific reasoning. Across its discussions, it examines the ongoing interplay between evidence and hypothesis to illustrate how astronomers evaluate celestial phenomena.

Designed for introductory astronomy courses, the text is offered alongside WebAssign digital resources. These materials feature Virtual Astronomy Labs 3.0, which includes 20 interactive simulation activities that incorporate real astronomical data.
