为什么月亮在这栋楼的顶上？规划。为了创造出这种惊人的叠加，这位天文摄影师进行了仔细的规划，包括确定相机的确切位置和拍摄的确切时间。这张照片拍摄于11月19日凌晨，接近月偏食的高峰期，当时月球正穿过地球的阴影。在这个时候，几乎整个月球——99.1%的面积——都在地球阴影中最黑暗的部分。这座建筑是智利的圣地亚哥大塔，是南美洲最高的建筑。虽然整个日食持续了令人印象深刻的6个小时，但这张照片必须在几秒钟内拍摄才能使其对准正确-地球的自转很快使建筑物偏离了直线。下一次地月食将是12月4日发生的日全食，但只能从地球的底部看到。APOD编辑（RJN）周一在线：美国宇航局最佳太空图像（&视频）值得注意的APOD提交：2021年11月19日的月食

Why is the Moon on top of this building? Planning. It took the astrophotographer careful planning -- including figuring out exactly where to place the camera and exactly when to take the shot -- to create this striking superposition. The single image featured was taken in the early morning hours of November 19, near the peak of the partial lunar eclipse that was occurring as the Moon passed through the Earth's shadow. At this time, almost the entire Moon -- 99.1 percent of its area -- was in the darkest part of the Earth's shadow. The building is the Gran Torre Santiago building in Chile, the tallest building in South America. Although the entire eclipse lasted an impressive six hours, this image had to be taken within just a few seconds to get the alignment right -- the Earth's rotation soon moved the building out of alignment. The next Earth-Moon eclipse will be a total eclipse of the Sun that will occur on December 4 -- but only be visible from the bottom of our world.
