This fourth edition has been carefully reviewed, revised and brought up-to-date with new text and photographs. The chapter on cosmology is significantly expanded to include new information about the origin of the universe and the large-scale structure of the universe. Also included are over thirty new photographs of planets, nebulas, galaxies and galaxy clusters. Every major topic of astronomy is described clearly and concisely. The Universe and Beyond addresses the questions that arise most often from those with a fascination for the night sky. Brimming with color illustrations, the book includes the Cassini-Huygens mission.
