點開這條絕美銀河

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.
晚上你可以沿著這條路走,因為它穿過了距離葡萄牙阿倫特約不遠的黑暗天空阿爾克瓦保護區(qū)。或者你可以停下來,抬頭,沿著銀河穿過天空。在6月3日拍攝的這張180度全景圖中,兩者都從地平線延伸到地平線。我們銀河系的名字,銀河系,確實是指它在天空中的外觀是一條銀河。galaxy這個詞本身起源于希臘語中的milk。在我們美麗的星球上,在無月的夜晚,從黑暗的天空中最容易看到銀河系的弧線,盡管沒有這張照片中那么明亮或多彩。發(fā)光的天體帶是由于銀河系平面上無數(shù)恒星的集體光太微弱,無法單獨區(qū)分。漫射的星光被銀河系模糊的星際塵埃云的暗條切斷。在這張全景夜景的頂部附近,銀河弧上方是明亮的織女星,銀河系的中央凸起位于右側(cè)地平線附近。
