人类自对于天空的第一眼开始就对星星产生了兴趣。有些恒星也许有它们自己的行星。如果是这样的话,我们就可以知道这些恒星是否存在生命。但问题在于,最近的一颗恒星在4光年以外。换句话来说,在到达地球之前,光线已经穿行了4年。乘坐火箭也需要千百年的时间才能抵达那个星球,因此,也许地球上没有人会造访它。
(仓促翻译,但意思应该不会错的)

自从人们抬起头来看天空,他们就已经对星星产生了兴趣。一些星星也许有他们自己的行星。如果那是真的,那我们可以知道他们上面有生命得存在。问题是,最近的星星离我们4光年远。换句话说,他们发出的光要经历4年才能到达我们这。可能地球上没有人能去参观那个星星因为火箭都要花100000年到达那。

给楼主翻译一下吧,我想看汉语的话应该能明白是什么意思:人类从他们仰望星空开始就一直对星星产生了浓厚的兴趣,这其中的一些星星也许有这自己的星系,如果这是真的话,那么我们可以推测他们之中应该有生命存在.不过问...

自从人类第一次抬头望星空,就开始对星星产生了兴趣。有些行星有自己的运行轨道。如果是那样的,那么其中一颗星球上可能会有生命迹象。问题是离我们最近的星球也有四光年的距离。换句话说,以光速从它驶向地球需要4年的时间。或许地球上没有人会登陆那个星球,因为乘火箭的话,需要1000000年才能到达。
