月球又称“月亮”。在望远镜发明之前，古代的人们只能在晴朗的夜晚，用眼睛仰望皎洁的明月。看到月亮表面有明有暗，形状奇特，于是人们就编出如嫦娥奔月、吴刚伐桂、玉免捣药等美丽神话。古希腊人则把月球看作美丽的狩猎女神阿尔忒弥斯，并且把女神狩猎时从不离身的银弓作为月球的天文符号。 The moon is also called the moon. Before the invention of telescope, ancient people could only look up at the bright moon with their eyes on a clear night. Seeing the moon's surface is bright and dark, and its shape is strange, people have made up Beautiful myths such as Chang'e running to the moon, Wu Gang cutting the laurel, Yu Mian tampering with medicine and so on. The ancient Greeks regarded the moon as Artemis, the beautiful hunting goddess, and regarded the silver bow that the goddess never left when hunting as the astronomical symbol of the moon. 月球基本上没有水，也就没有地球上的风化、氧化和水的腐蚀过程，也没有声音的传播，到处是一片寂静的世界。 Basically, there is no water on the moon, so there is no weathering, oxidation and water corrosion process on the earth, and there is no sound transmission. There is a silent world everywhere. 月球上几乎没有大气，因而月球上的昼夜温差很大。白天，在阳光垂直照射的地方，温度高达127℃；夜晚温度可低到-183℃。由于没有大气的阻隔，使得月面上日光强度比地球上约强1／3左右；紫外线强度也比地球表面强得多。由于月球大气少，因此在月面上会见到许多奇特的现象，如月球上的天空呈暗黑色，太阳光照射是笔直的，日光照到的地方很明亮；照不到的地方就很暗。因此才会看到的月亮表面有明有暗。由于没有空气散射光线，在月球上星星看起来也不再闪烁了。 |
