为什么这个月亮看起来如此不寻常？一个关键的原因是它鲜艳的红色。这种颜色是由地球大气对蓝光的偏转造成的，这和白天天空呈现蓝色的原因是一样的。月球也出现了不寻常的扭曲。它奇怪的结构是地球大气层中由于温度或压力的突然变化而产生的不同折射光的光学效应。月球看起来如此不寻常的第三个原因是，碰巧有一架飞机在月球前面飞行。这张风景如画的月亮是两周前在意大利都灵上空拍摄的。我们熟悉的盘旋在空中的球体是一个不寻常的四连珠的一部分，包括两个历史悠久的地面建筑：附近山上的圣米歇尔圣坛和远处的苏佩尔加大教堂。你的天空惊喜：APOD在你朋友的生日上展示了什么照片？(1995后)

Why does this Moon look so unusual? A key reason is its vivid red color. The color is caused by the deflection of blue light by Earth's atmosphere -- the same reason that the daytime sky appears blue. The Moon also appears unusually distorted. Its strange structuring is an optical effect arising from layers in the Earth's atmosphere that refract light differently due to sudden differences in temperature or pressure. A third reason the Moon looks so unusual is that there is, by chance, an airplane flying in front. The featured picturesque gibbous Moon was captured about two weeks ago above Turin, Italy. Our familiar hovering sky orb was part of an unusual quadruple alignment that included two historic ground structures: the Sacra di San Michele on the near hill and Basilica of Superga just beyond.
