为什么阴天的月亮有时看起来是彩色的？这种效应被称为月冕，它是由光在一个中间但大部分是透明的云中的单个大小相似的水滴周围的量子力学衍射产生的。因为不同颜色的光有不同的波长，所以每种颜色的衍射也不同。月球日冕是为数不多的可以用肉眼轻易看到的量子力学色彩效应之一。太阳日冕有时也很明显。这张特色照片是上个月在法国巴黎拍摄的。从埃菲尔铁塔上发出的蓝色信标没有影响到彩色的月冕。传送门宇宙：随机APOD生成器

Why does a cloudy moon sometimes appear colorful? The effect, called a lunar corona, is created by the quantum mechanical diffraction of light around individual, similarly-sized water droplets in an intervening but mostly-transparent cloud. Since light of different colors has different wavelengths, each color diffracts differently. Lunar coronae are one of the few quantum mechanical color effects that can be easily seen with the unaided eye. Solar coronae are also sometimes evident. The featured image was taken last month from Paris, France. The blue beacon emanating from the Eiffel Tower did not affect the colorful lunar corona. Portal Universe: Random APOD Generator
