在這幅暮色蒼茫的山景照片中,一輪懸掛 26 小時的明月在義大利多洛米蒂山脈的峭壁輪廓後熠熠生輝。一秒鐘的長時間曝光拍攝於 3 月 30 日月落附近。雖然只能看到太陽照耀下的月球表面的一小部分,但月球的大部分圓盤都可以透過地光看到,因為明亮的地球行星反射的光線照亮了月球的近側。地輝也被稱為月球的灰燼之光, 500 多年前,達芬奇曾用地球海洋反射的陽光照亮月球黑暗的表面來描述地輝。當然,"地球陽光 "只是人們最熟悉的 "行星陽光 "的一個例子。"行星陽光 "是指月球黑暗部分被其行星反射的光線照亮的微弱現象。
原文:A 26 hour old Moon poses behind the craggy outline of the Italian Dolomites in this twilight mountain and skyscape. The one second long exposure was captured near moonset on March 30. And while only a a sliver of its sunlit surface is visible, most of the Moon's disk can be seen by earthshine as light reflected from a bright planet Earth illuminates the lunar nearside. Also known as the Moon's ashen glow, a description of earthshine in terms of sunlight reflected by Earth's oceans illuminating the Moon's dark surface was written over 500 years ago by Leonardo da Vinci. Of course earthshine is just the most familiar example of planetshine, the faint illumination of the dark portion of a moon by light reflected from its planet.
