Explanation: If the full Moon suddenly faded, what would you see? The answer was recorded in a dramatic time lapse video taken during the total lunar eclipse in 2011 from Tajikistan. During a total lunar eclipse, the Earth moves between the Moon and the Sun, causing the moon to fade dramatically. The Moon never gets completely dark, though, since the Earth’s atmosphere refracts some light. As the featured video begins, the scene may appear to be daytime and sunlit, but actually it is a nighttime and lit by the glow of the full Moon. As the Moon becomes eclipsed and fades, background stars become visible and here can be seen reflected in a lake. Most spectacularly, the sky surrounding the eclipsed moon suddenly appears to be full of stars and highlighted by the busy plane of our Milky Way Galaxy. The sequence repeats with a closer view, and the final image shows the placement of the eclipsed Moon near the Eagle, Swan, Trifid, and Lagoon nebulas. Nearly two hours after the eclipse started, the moon emerged from the Earth’s shadow and its bright full glare again dominated the sky. Later today or tomorrow, depending on your location relative to the International Date Line, a new total lunar eclipse will take place — with totality being primarily visible over northeastern Asia and northwestern North America.

说明：如果满月突然暗去，那你能看见甚么？上面这部2011年摄于塔吉克斯坦的月全食缩时视频，可以解开这个疑惑。在月全食期间，地球运行到月亮与太阳之间，造成月亮突然变暗。不过，因为地球大气折射了部分阳光，所以月亮并不会完全黝黑。在这部主题视频开头时，画面看似是阳光普照的白天，但其实是千真万确的黑夜，大地受到满月的照耀。随着月亮进入月食阶段，明月变暗，背景恒星显现并倒映在湖面上。而最壮观的画面，则是全食月周围的天空突然满是繁星，连壮丽的银河盘面也清楚可见。紧接着视频的视野拉近，最后的画面更突显了全食月附近的老鹰星云、天鹅星云、三叶星云与礁湖星云。在月食开始的2小时后，月亮从地球影子里复现，它的炫光再次宰制天空。端视你与国际换日线的相对位置而异，在今天或明天将再发生一例月全食，不过全食可见的区域主要在亚洲东北角及北美洲的西北部。
