点开这条绝美银河

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.

晚上你可以沿着这条路走，因为它穿过了距离葡萄牙阿伦特约不远的黑暗天空阿尔克瓦保护区。或者你可以停下来，抬头，沿着银河穿过天空。在6月3日拍摄的这张180度全景图中，两者都从地平线延伸到地平线。我们银河系的名字，银河系，确实是指它在天空中的外观是一条银河。galaxy这个词本身起源于希腊语中的milk。在我们美丽的星球上，在无月的夜晚，从黑暗的天空中最容易看到银河系的弧线，尽管没有这张照片中那么明亮或多彩。发光的天体带是由于银河系平面上无数恒星的集体光太微弱，无法单独区分。漫射的星光被银河系模糊的星际尘埃云的暗条切断。在这张全景夜景的顶部附近，银河弧上方是明亮的织女星，银河系的中央凸起位于右侧地平线附近。
