商品簡介 |
| The Ever-Changing Sky is a comprehensive and uniquely non-mathematical guide to spherical astronomy. In a clear and lucid text, it guides through terrestrial and celestial co-ordinate systems, time measurement and celestial navigation, on to the stars and constellations (with useful star maps provided), the motions and appearance of the Moon and planets, tides and eclipses, and the smaller bodies of the Solar System (asteroids, meteors, meteorites and comets). There is also a brief overview of atmospheric phenomena. This text is invaluable to students of naked-eye astronomy, amateur and professional astronomers, and more general readers wanting to know how the night sky changes. |
