Children's LiteratureGenerally, the books from "Isaac Asimov's 21st Century Library of the Universe" series are soundly written with plenty of clear scientific explanations and interesting facts, but they are not terribly exciting. Each book reads like the next, as they all progress through the history of scientific discoveries leading to what we know about a particular celestial body today. But this volume escapes the rigid formatting and repetitive writing of the series and shines in its impressive content. Asimov and Hantula explain solar flares, why the sun is hot, how the sun came to be, the historical worship of the sun, and how scientists study the star. It even includes a marvelous collection of photographs that show solar flares in action as well as the shape of the sun's corona. Showing readers these beautiful engaging pictures is a marvelous way to make the star more accessible. One aspect missing from the book is an explanation of the sun's life as a star. However, this is certainly one of the better volumes from the series. It is a wonderful addition to a classroom or school library. 2004 (orig. 1988), Gareth Stevens Publishing, Ages 6 to 10.
