最後的滿月
The Last Full Moon

被北半球一些人稱為十二月冷月或長夜之月的 2023 年最後一輪滿月正在這座超現實的山峰和天空中升起。這個達利斯式的場景是在義大利格拉巴山附近用相機和長焦鏡頭一次性曝光拍攝的。不過，滿月並沒有融化。它在地平線附近拉伸和扭曲的外觀是由於沿視線折射的變化造成的，並在明亮的月盤上形成了移動的影像或海市蜃樓。大氣折射的變化與溫度和密度迥異的大氣層相對應。由於這次滿月升起的視線較長，大氣折射產生的其他影響還包括在扭曲的月球下緣隱約看到的紅色細邊，以及沿月球頂部看到的綠色細邊。
原文：Known to some in the northern hemisphere as December's Cold Moon or the Long Night Moon, the last full moon of 2023 is rising in this surreal mountain and skyscape. The Daliesque scene was captured in a single exposure with a camera and long telephoto lens near Monte Grappa, Italy. The full moon is not melting, though. Its stretched and distorted appearance near the horizon is caused as refraction along the line of sight changes and creates shifting images or mirages of the bright lunar disk. The changes in atmospheric refraction correspond to atmospheric layers with sharply different temperatures and densities. Other effects of atmospheric refraction produced by the long sight-line to this full moon rising include the thin red rim seen faintly on the distorted lower edge of the Moon and a thin green rim along the top.
