你不能沿着银河系走。尽管如此，在黑暗的天空下，你还是可以探索它。在一个漆黑无月的夜晚，在天空中划过的苍白的光带看起来确实像是一条穿过天空的路径。发光的天体带是遥远恒星发出的微弱的集体光，被大片模糊的星际尘埃云切断。它位于我们银河系的平面上，因为它看起来像银河系而得名。从伽利略时代开始，用望远镜观察天空的人就发现银河系充满了无数的恒星和宇宙奇观。

You can't walk along the Milky Way. Still, under a dark sky you can explore it. To the eye the pale luminous trail of light arcing through the sky on a dark, moonless night does appear to be a path through the heavens. The glowing celestial band is the faint, collective light of distant stars cut by swaths of obscuring interstellar dust clouds. It lies along the plane of our home galaxy, so named because it looks like a milky way. Since Galileo's time, the Milky Way has been revealed to telescopic skygazers to be filled with congeries of innumerable stars and cosmic wonders.
