3月14日是满月。在一个适当的圆周率日庆祝活动中，月球与地球天空中的太阳在黄道经度上的距离为3.14弧度（180度）。对于圆周率派的粉丝和夜空的粉丝来说，在那一天，月球也在月全食中直接穿过地球的本影。在晴朗的天空中，月食的颜色会很鲜艳。智利塞罗·托洛洛天文台在这张时间序列合成图像中记录了深红色的阳光散射到地球的阴影中，暗月盘反射出深红色的阳光。这幅月球三联画捕捉到了持续约一个小时的月全食阶段的开始、中间和结束。在阴影边缘较亮的月球边缘可以看到微弱的蓝色，这是由于阳光通过地球平流层的臭氧层过滤造成的。成长画廊：2025年3月的月全食

On March 14 the Moon was Full. In an appropriate celebration of Pi day, that put the Moon 3.14 radians (180 degrees) in ecliptic longitude from the Sun in planet Earth's sky. As a bonus for fans of Pi and the night sky, on that date the Moon also passed directly through Earth's umbral shadow in a total lunar eclipse. In clear skies, the colors of an eclipsed Moon can be vivid. Reflecting the deeply reddened sunlight scattered into Earth's shadow, the darkened lunar disk was recorded in this time series composite image from Cerro Tololo Observatory, Chile. The lunar triptych captures the start, middle, and end of the total eclipse phase that lasted about an hour. A faint bluish tint seen just along the brighter lunar limb at the shadow's edge is due to sunlight filtered through Earth's stratospheric ozone layer.
