晚上你可以沿着这条路走，它穿过黑暗天空保护区，离葡萄牙阿连特茹不远。或者你可以停下来，抬头看，沿着银河穿过天空。在这张拍摄于6月3日的180度全景图中，这两幅画从地平线延伸到地平线。我们星系的名字，银河系，确实指的是它在天空中呈银河状的样子。银河这个词本身来源于希腊语中的牛奶。从我们美丽的星球上，在没有月亮的夜晚，从黑暗的天空区域最容易看到银河系的弧线，尽管不像这张照片那么明亮或丰富多彩。发光的天体带是由于银河平面上无数恒星的集体光太微弱而无法单独区分。漫射的星光被星系中模糊的星际尘埃云的黑暗条纹所切割。在这幅全景夜景的顶部，明亮的织女星站在银河系的弧线上方，右边是靠近地平线的星系中央凸起。

At night you can follow this road as it passes through the Dark Sky Alqueva reserve not too far from Alentejo, Portugal. Or you could stop, look up, and follow the Milky Way through the sky. Both stretch from horizon to horizon in this 180 degree panorama recorded on June 3. Our galaxy's name, the Milky Way, does refer to its appearance as a milky path in the sky. The word galaxy itself derives from the Greek for milk. From our fair planet the arc of the Milky Way is most easily visible on moonless nights from dark sky areas, though not quite so bright or colorful as in this image. The glowing celestial band is due to the collective light of myriad stars along the galactic plane too faint to be distinguished individually. The diffuse starlight is cut by dark swaths of the galaxy's obscuring interstellar dust clouds. Standing above the Milky Way arc near the top of this panoramic nightscape is bright star Vega, with the galaxy's central bulge near the horizon at the right.
