首先来看太阳。日全食发生时，月球遮挡住了站在地球上本影内的观测者观看太

First look at the sun. Total solar eclipse occurs when the moon blocking the observer standing in the umbra of the earth to watch the sun line of sight, the observer see around the sun is black space, revealing the stars, the earth as night. My question is, sunlight it? Why not put the sun to illuminate the space around it? 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.

First look at the sun. When a total solar eclipse occurs, the moon blocks the view of observers standing in the Earth's shadow to see the sun, and observers see the sun's surroundings are black and dark, with stars revealing and the earth as if it were at night. My question is, what about the sun? Why didn't the sun light up the space around it? When the total solar eclipse is over, the moon moves away, the sun emerges, and the blue sky, white clouds and earth are illuminated again. If a man disappears from my sight behind a wall, it is clear that the wall is blocking an image of his body. This tells us that it is the image of the sun that was previously obscured by the moon, not the sun, that illuminates the blue sky, the white clouds and the earth.

First, look at the sun. When the total solar eclipse occurs, the moon blocks the observer's view of the sun standing in the earth's umbra. The observer sees that the sun is surrounded by black space, with stars exposed, and the earth is like night. My question is, what about sunlight? Why doesn't the sun illuminate the space around it? 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.
