DK 目击者天文学 Eyewitness Companions Astronomy 2006

从研究太阳系最小成员到最遥远的星系，天文学是一门无止境的科学。它试图回答最基本的问题：我们来自哪里，一个人吗？但它仍然是一门科学，业余爱好者可以发挥作用。
From the study of the smallest members of the solar system to the most distant galaxies, astronomy is a science that knows no bounds. it attempts to answer the most fundamental questions: where did we come from, and are we alone? yet it remains a science in which amateurs can play a role.
