在月全食期间，月球的外观是如何变化的？这段特色的延时视频经过数字处理，以在2018年1月31日5小时的月食期间保持月球的明亮和中心。起初，满月是可见的，因为只有满月才能经历月食。恒星在背景中移动，因为月球在月食期间绕地球运行。然后就可以看到地球的圆形阴影在月球上移动。阴影边缘的浅蓝色色调与地球天空是蓝色的原因有关，而阴影中心的深红色色调与太阳在接近地平线时呈现红色的原因有关。明天晚上，生活在东亚、澳大利亚和北美大部分地区的人们可能会看到全血月月食。这里的“血”指的是（可能是）月全食时的红色。几乎超空间：随机APOD生成器

How does the Moon's appearance change during a total lunar eclipse? The featured time-lapse video was digitally processed to keep the Moon bright and centered during the 5-hour eclipse of 2018 January 31. At first the full moon is visible because only a full moon can undergo a lunar eclipse. Stars move by in the background because the Moon orbits the Earth during the eclipse. The circular shadow of the Earth is then seen moving across the Moon. The light blue hue of the shadow's edge is related to why Earth's sky is blue, while the deep red hue of the shadow's center is related to why the Sun appears red when near the horizon. Tomorrow night, people living in Eastern Asia, Australia, and much of North America may get to see a Total Blood Moon Lunar Eclipse. Here the term blood refers to the (likely) red color of a fully eclipsed Moon. Almost Hyperspace: Random APOD Generator
