A Moon Dressed Like Saturn

Explanation: Why does Saturn appear so big? It doesn’t — what is pictured are foreground clouds on Earth crossing in front of the Moon. The Moon shows a slight crescent phase with most of its surface visible by reflected Earthlight known as ashen glow. The Sun directly illuminates the brightly lit lunar crescent from the bottom, which means that the Sun must be below the horizon and so the image was taken before sunrise. This double take-inducing picture was captured on 2019 December 24, two days before the Moon slid in front of the Sun to create a solar eclipse. In the foreground, lights from small Guatemalan towns are visible behind the huge volcano Pacaya.

说明: 土星怎会这么大?因为它不是土星,只是地球的浮飘过月亮前方造成的景观。当时月亮带着纤细的蛾眉相,其他大片的月面因反射地照光而散发暗淡的灰光。受到太阳直接照耀的月表,只有底部的狭窄蛾眉亮区,因此太阳必然是在地平面下方,而且时值日出之前。这幅多看二眼才会恍然的照片,摄于2019年12月24日,在月亮运行到太阳前方造成一次日食的2天之前。在前景庞大帕卡亚火山后方的人间灯火,是来自危地马拉的小城镇。
