義大利上空的四重排列
A Quadruple Alignment over Italy

為什麼這個月球看起來如此與眾不同？ 一個關鍵原因是它鮮豔的紅色。這種顏色是由地球大氣層對藍光的偏轉造成的--這與白天天空呈現藍色的原因相同。 月球看起來也異常扭曲。 月球的奇特結構是一種光學效應，是由於地球大氣層中的各層由於溫度或壓力的突然差異而對光線產生了不同的折射。 月球看起來如此不尋常的第三個原因是，前面偶然飛過一架飛機。大約兩週前，我們在義大利都靈上空拍攝到了這幅如詩如畫的長月。我們熟悉的懸停的天空球體是不尋常的四重排列的一部分，其中包括兩個歷史悠久的地面建築：近處山上的聖米歇爾教堂（Sacra di San Michele）和遠處的索普加大教堂（Basilica of Superga）。 您的天空驚喜在您朋友的生日上，APOD 報道了哪張照片？ ( 1995 年後)
原文：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.
