Set the alarm clock! The most spectacular “dog eating the sun” of this century will be staged on June 21

Have you ever seen “dog eats the sun”? This is actually the phenomenon of solar eclipse. If the moon moves to the middle of the sun and the earth, and the three are in a straight line, the moon will block the light from the sun to the earth, and the shadow behind the moon will just fall on the earth. At this time, the phenomenon of solar eclipse occurs.

Solar eclipses are divided into partial solar eclipses, total solar eclipses and annular solar eclipses.

The occurrence of these three kinds of solar eclipses is related to the position of the sun, the moon and the earth, and also depends on the distance between the moon and the earth.

As we all know, the moon goes around the sun as well as the earth. When the moon reaches a distant place, the shadow of the moon can not reach the ground, it will also block the light from the sun to the moon. In short, the sun, the earth and the moon are all in a straight line. However, because the moon is too small to completely block the sun, it only blocks the central area of the sun, exposing the edges around the sun. So the sun looks like a “ring.”.

When was the first record of an annular eclipse?

There are records about the phenomenon of annular solar eclipse in the ancient civilization countries of the world. There are six ancient solar eclipses recorded on the pottery vessels and broken stone tablets obtained from the ruins of Babylon and ninesia. One of the earliest occurred in 911 BC. It was once thought that this was the oldest record of a solar eclipse in the world.

However, there is also a solar eclipse recorded in Yinzheng in Shangshu. There was an annular eclipse in the 21st century BC, but the officials in charge of observing the sky at that time not only did not predict the time of the eclipse, but also got drunk on the day of the eclipse, so they were all executed for neglect of duty. Therefore, it has been recognized by Chinese and foreign astronomers as the earliest record of solar eclipse in the world.
