How far can you see? The Andromeda Galaxy 2.5 million light years away is the most distant object easily seen by the unaided eye. Other apparent denizens of the night sky, stars, clusters, and nebulae, typically range from a few hundred to a few thousand light-years away and lie well within our own Milky Way Galaxy. Also known as M31, the Andromeda Galaxy is the faint smudge near top center of this Earth and skyscape, taken from eastern Italy, near Monte Conero on the Adriatic sea coast. From a few centimeters to a few million light-years, the picture demonstrates a stunning range of vision. Though galaxy and seaside rocks could be seen with the eye on that clear summer night, no camera captured this view in a single exposure. Because the stars trailed above the horizon while the picture was made, separate exposures tracking the stars were combined with one of rocks and cliffs made with the camera steadied to create the tantalizing scene.
中文翻譯:
在這個清澈的夏夜，你可以看到距離地球約 250 萬光年的仙女座星系（Andromeda Galaxy），這是肉眼能夠輕易看見的最遙遠物體。其他在夜空中可見的星星、星團和星雲通常距離幾百到幾千光年，這些都屬於我們的銀河系（Milky Way Galaxy）。這幅來自意大利東部、亞得里亞海海岸的蒙特科內羅（Monte Conero）拍攝的照片中，仙女座星系（M31）是一個位於圖片上方中心附近的微弱光暈。
從幾厘米到幾百萬光年，這幅圖片展示了驚人的視覺範圍。雖然在這樣清澈的夏夜能夠用肉眼看到星系和海邊的岩石，但沒有相機能夠在一個曝光中捕捉這一景象。由於星星在拍攝期間沿著地平線移動，攝影師將追蹤星星的多個曝光與一張穩定拍攝岩石和懸崖的照片相結合，創造出這個引人入勝的畫面。
