为什么土星看起来这么大？它没有——照片上的是地球上的前景云穿过月球前面。月球呈现出轻微的月牙形，其大部分表面被反射的地球光称为灰光。太阳从底部直接照亮了明亮的月牙，这意味着太阳一定在地平线以下，所以这张照片是在日出前拍摄的。这张双重引人注目的照片是在2019年12月24日拍摄的，就在月球滑到太阳前面形成日食的两天前。在前景中，从巨大的帕卡亚火山后面可以看到危地马拉小镇的灯光。新闻：APOD获得国际天文学联合会首届外联奖

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. News: APOD Receives First Outreach Prize from the International Astronomical Union
