This is an original and quite a successful book. With very brief text, with pictures (by Dorothy Waugh) that are both decorative and informative, this is a picture book and expanded definition of the basic facts of astronomy. The sun, the planets, the earth, day and night, climate, eclipses, the individual planets, stars, comets, meteors, atoms, nebulas. Then something about telescopes and their use. The author's husband is one of the astronomers at Mt. Wilson Observatory, and this book has a note of authority, without being too bald in statement.
