From the Big Bang to Planet X: The 50 Most-Asked Questions about the Universe ... and Their Answers

The author has succeeded in writing a useful, enjoyable, and eminently readable book. The questions range over the whole domain of astronomy and include those concerned with current areas of astronomical research. . . . In addition to giving answers that are accessible to a general audience, the author often uses easily visualized models to describe, for example, the relative size of the solar system or the thickness of Jupiter's rings. The diagrams and photographs (many taken by the author himself) add significantly to the explanations. Obviously, in a book of this length that covers so wide a range of topics, it is not possible to go into great depth on any particular subject. However, the author has wisely included an extensive reading list for further study, organized question by question.

I love astronomy, but most of the books I read about it are long and drawn-out, and too difficult and advanced for a high schooler to read. However, this book is easy enough for elementary schoolers to read. It's very informative, explained very well, and even has pretty pictures for those who are too lazy to read the whole book. :) I definitely recommend it!
