一个26小时前的月亮在意大利白云石嶙峋的轮廓后面，在这片朦胧的山脉和天空中摆姿势。这张1秒长的曝光照片是在3月30日月落附近拍摄的。虽然只有一小部分被阳光照射的月球表面是可见的，但大部分的月球表面都可以通过地球的光线看到，因为地球反射的光线照亮了月球的近侧。500多年前，列奥纳多·达·芬奇（Leonardo da Vinci）就地球海洋反射的阳光照亮了月球黑暗的表面，这一描述也被称为月球的灰光。当然，地球光只是我们最熟悉的行星光的一个例子，行星光是由行星反射的光线照射到月球的黑暗部分。

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.
