Book Description
Editorial Reviews
From Booklist
Gr. 5-7. The photo-essay format is attractive, with large, mysterious pictures of skies in dazzling light and color, but the physics of what causes the Northern Lights isn't easy to understand. It does help that Souza tries to explain the action of solar-wind particles, magnetic fields, and atmospheric gases in terms of daily things around the house, from images on the TV screen to the action of neon lights and the swirling of clothes in the drier. She also includes information on where and when the auroras can be seen, a folklore section of fascinating facts, and a glossary. This will be useful for curriculum support and discussion.

From Kirkus Reviews
For centuries, humanity's fascination with northern lights has generated myths and superstitious awe. The aurora's physics, too, is awesome: high energy particles streaming from the sun are captured and focused by Earth's magnetic field to collide with and excite gas molecules; as they return to a stable energy state, photons are emitted, creating colorful visible light. Souza's lucid explanation of the phenomenon is generously illustrated with clear diagrams, maps, and superb color photos. Except during solar flares and unusual solar activity, only Americans in the northern states can experience the aurora directly; this book may inspire a special trip. A beautifully presented example of a relatively narrow slice of science that nicely illuminates wider topics. Glossary; index. (Nonfiction. 10+) -- Copyright ©1994, Kirkus Associates, LP.
