译文
人们常常会观看美丽的夜空。世界上的许多古人曾密切研究星星来判断神的痕迹。中美洲和墨西哥的玛雅人和阿兹台克人建造很高的建筑来观星。埃及、希腊、意大利和中国的古人也研究星象。居住在太平洋岛屿上的人利用星象来寻找穿越海洋的路。
地球上的人今天仍然还看关于星象的信息——不是关于古老的神,而是关于宇宙。现代技术使得观看在太空中成千上万的数百万千米远的物体成为可能。
如果你居住在地球的北半球,你可以在向北的夜空中搜寻并找到北极星。
古人观看北极星很长一段时间,发现它移动得很少。它总是可以在北部天空的同一个地方找到。古人利用北极星来引导他们的船只穿越海洋。
在地球的南半球,你可以在夜空中看到半人马座阿尔法和贝塔星。它们指向一群叫做“南十字星座”的美丽的星星。古人利用南十字星座来引导他们的船只。
