Explanation: On November 8 the Full Moon turned blood red as it slid through Earth’s shadow in a beautiful total lunar eclipse. During totality it also passed in front of, or occulted, outer planet Uranus for eclipse viewers located in parts of northern America and Asia. For a close-up and wider view these two images were taken just before the occultation began, captured with different telescopes and cameras from the same roof top in Shanghai, China. Normally very faint compared to a Full Moon, the tiny, pale, greenish disk of the distant ice giant is just to the left of the Moon’s edge and about to disappear behind the darkened, red lunar limb. Though only visible from certain locations across planet Earth, lunar occultations of planets are fairly common. But for this rare “lunar eclipse occultation” to take place, at the time of the total eclipse the outer planet had to be both at opposition and very near the ecliptic plane to fall in line with Sun, Earth, and Moon.

说明: 在11月8日，满月于美丽的月全食期间穿过地球的影子里，暂时披上了血红的外衣。在全食期间，它还通过太阳系外围的天王星之前方，让位在北美和亚洲部分地区的月食观察者，同时见到了月掩天王星的景观。而提供特写及大视野景观的这2幅图像，分别使用不同的望远镜及相机，摄于中国上海市的同一座屋顶。图像中，和满月相较，通常很细小昏暗的这颗遥远冰质巨行星之泛绿盘面，则位在月亮的左侧，而且即将消失在昏暗红化的临边后方。虽然月掩行星是在某些地表区域才得见的景观，但这类事件相当常见。然而，要见到这种极罕见的“食月掩星”事件，在月全食期间，外围行星得位在冲的位置，而且必须非常靠近黄道面，才能和太阳、地球、及月亮连成一直线。
