"The Astronomy Encyclopedia is an interstellar tour led by the acclaimed Sir Patrick Moore, England's ambassador to the night sky. In more than 3000 alphabetically organized articles and over 600 photographs, star maps and explanatory diagrams, it covers everything and everyone from the American Association of Variable Star Observers to zodiacal light.".

"The articles provide authoritative yet accessible information on subjects such as our Galaxy, the Sun and planets, life in the Universe, optical and radio telescopes, stars, black holes, astrophysics, observatories, astronomical photography, space programs, the constellations and famous astronomers.

Supporting these articles are shorter entries on planetary features and satellites, asteroids, observational techniques, comets, satellite launchers, meteors, and subjects as diverse as software for astronomy and the structure of meteorites."--BOOK JACKET.
