巴黎上空的月暈
A Lunar Corona over Paris

為什麼多雲的月亮有時會呈現出五彩斑斕的顏色?這種效果被稱為 "月球日冕",它是由中間大部分透明的雲層中單個大小相似的水滴周圍的光量子機械衍射產生的。由於不同顏色的光有不同的波長,因此每種顏色的衍射也不同。月球日冕是少數幾種量子力學色彩效應之一,可以用肉眼輕易看到。 太陽日冕有時也很明顯。這張照片是上個月從法國巴黎拍攝的。 埃菲爾鐵塔發出的藍色訊號燈並沒有影響到色彩斑斕的月冕。 宇宙之門隨機 APOD 生成器
原文: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
