首先来看太阳。日全食发生时，月球遮挡住了太阳，站在地球本影里的观测者看

First look at the sun. Total solar eclipse occurs when the moon blocking the sun, standing in the umbra of Earth around the sun observers see is blackness of space, revealing the stars, the earth as night. My question is, why did not the sun to illuminate the space around the sun? When the end of a total solar eclipse, the moon is removed, exposed sun, blue sky, white clouds and the earth was again illuminated. If a person disappeared behind a wall from my sight, apparently this wall blocked his body image. This tells us that illuminate blue sky, white clouds and the earth that was previously hidden moon image of the sun, not the sun.

首先来看太阳。日全食发生时，月球遮挡住了太阳，站在地球本影里的观测者看到太阳的周围是漆黑的太空，繁星显露，大地如同夜晚。我的疑问是，阳光为什么没把太阳周围的太空给照亮？当日全食结束，月球移开后，太阳露出来，蓝天、白云和大地再被照亮。假如一个人从我的视线里消失在一面墙的后面，显然这面墙挡住的是他身体的影像。这在告诉我们，照亮蓝天、白云和大地的是先前被月球遮住的太阳的影像，而不是阳光。

First, look at the sun. When the total solar eclipse occurs, the moon blocks the sun. The observer standing in the earth's shadow sees that the sun is surrounded by dark space, with stars exposed. The earth is like night. My question is, why doesn't the sun illuminate the space around the sun? At the end of the total eclipse, when the moon moved away, the sun came out, and the blue sky, white clouds and the earth were illuminated again. If a person disappears from my sight behind a wall, it is obvious that the wall is blocking the image of his body. This tells us that the image of the sun, which was previously covered by the moon, rather than the sun, lights up the blue sky, white clouds and the earth.<br>
