Explanation: Only natural colors of the Moon in planet Earth’s sky appear in this creative visual presentation. Arranged as pixels in a framed image, the lunar disks were photographed at different times. Their varying hues are ultimately due to reflected sunlight affected by changing atmospheric conditions and the alignment geometry of Moon, Earth, and Sun. Here, the darkest lunar disks are the colors of earthshine. 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. But stand farther back from your monitor or just shift your gaze to the smaller versions of the image. You might also see one of da Vinci’s most famous works of art.

说明: 这幅很有创意的影像，呈现月亮在地球天空中的各种天然色泽。作为这张影像像素的众多月盘，则是摄于不同的时间点。它们多变的色泽，取决于不同地球大气条件所反射的阳光，以及月亮、地球和太阳的几何排列。其中，最黝黑的那些月盘反映了地照光的色泽。远在500多年前，达文西就描述过受到地球海洋反射的阳光，会照亮月球黝黑的夜面。然而，如果离你的电脑萤幕远一点，然后再把视线移向右下的缩小版影像，你或许能见到达文西最著名的画作之一。
