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?但这仍然是一门科学,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.
