Grade 4–6—Jefferis ranges through the solar system and then far beyond in these volumes. The first book begins with a summary look at galactic types and origins, then goes on to describe cores, halos, and other structures with special reference to the Milky Way. It closes with a smattering of advice for young sky watchers and a spread of general facts about galaxies. Similarly in the second title, the author explains what space probes are for, names many that have visited each of the major planets, and then suggests where models and mock-ups (since they can't be observed directly) might be found. The third book focuses on important observatories—earthbound and orbiting—along with types of telescopes—and concludes with brief observations about binoculars and cameras. All three volumes are designed with easily digestible blocks of question-and-answer text sharing page space with large, sharply reproduced space photos and graphic art. They all close with cursory lists of further resources. The information in Galaxies is readily available elsewhere, but Space Probes and Star Spotters provide quick, useful surveys of significant discoveries about space and some of the high-tech tools that were used to make them.—John Peters, New York Public Library
