In the last month of 2021, the astronomical wonders of the world can be said to be quite a lot, mainly 3, the first and one of the three major meteor showers in the northern hemisphere, the Gemini meteor shower, is expected to reach up to 150 per hour. Second, the moon covers Mars. This astronomical spectacle is because the moon obscures Mars, and a large area of our country can be observed if the climatic conditions are better, because most of the northern region is in the observation belt, so you can prepare for it.
Third, a rare total solar eclipse, and this total solar eclipse is also the only one in 2021 and will appear on December 4. Judging from the situation of these three major celestial phenomena, the biggest attraction may be this total solar eclipse, after all, the other two astronomical wonders are more conventional. When it comes to total solar eclipses, many people are saying that this is the advent of an ominous omen, just like the "red moon" we said before, there are still many people who think that this is an ominous omen, what is the situation? Let's take a look.
Total solar eclipse is a kind of solar eclipse, and the eclipse is divided into four parts, namely partial solar eclipse, total solar eclipse, annular solar eclipse, and total annular eclipse. This is the most typical total solar eclipse process, and the principle of eclipse is basically the same, that is, the moon moves to the middle of the sun and the earth, if the three are exactly in a straight line, the moon will block the light of the sun shooting at the earth, and the black shadow behind the moon just falls on the earth, when the eclipse phenomenon occurs.
So, a total solar eclipse is only one part of the eclipse. The biggest highlight of the total solar eclipse - that is, some places on the earth where the sunlight is completely blocked by the moon, and when the celestial phenomenon reaches its peak, we will see a different "black celestial body". However, the entire total solar eclipse is divided into five stages: initial loss, eclipse, eclipse, light, and recovery, of which eclipse is the peak of the total solar eclipse. However, during the total solar eclipse phase, a typical celestial phenomenon appears.
That's what we call "Tengu Eclipse Day." Speaking of this celestial phenomenon, both young people and old people may have been "familiar" and have seen it. However, because the moon is smaller than the earth, coupled with the occurrence of the process of movement, it will form a spectacle of "Tengu Eclipse Day", which will trigger a heated discussion among many people. And as long as the spectacle of "Tengu Eclipse Day" appears, it will inevitably make many people think of folk rumors, so it is also said that there is a "bad omen".
In fact, after seeing our explanation above, everyone should also have an understanding of the occurrence of the total solar eclipse. What's more, this is not the first time that a "total solar eclipse" has occurred globally. In 2009, there was a total solar eclipse in China, and a wide range of areas such as Sichuan, Chongqing, Hubei, Hunan, Anhui, Jiangsu, Zhejiang and Shanghai in China have seen the occurrence of total eclipses, and other parts of the country can be seen.
If it is an "ominous omen" coming, is something big already happening? It is clearly unscientific. It is ominous to say that the total solar eclipse and the tengu eclipse the moon are ominous, mainly because some people have accepted the ancient ideas, and the ancient rumors - the tengu eclipse day caused damage to the sun, which naturally caused fear, coupled with the guidance of many people, so that people mistakenly thought that the eclipse heralded the "bad omen". Many people in our country believe that evil gods such as "tengu" oppose people and deliberately destroy the sun on which all things depend.
Therefore, "spreading false rumors" makes everyone mistakenly think that when these celestial phenomena appear, something will happen, and many people are unwilling to see it, which is completely the work of thought. Obviously this is not credible and unscientific. Although the number of total solar eclipses is not large, from the recorded situation, it has no major impact at all.
However, when it appears, there is a probability of affecting the ionosphere changes in the upper parts of the atmosphere, which may temporarily cause certain interference to the radio medium-wave and short-wave communications that the signal needs to reflect through the ionosphere, but the use of ultra-short wave FM broadcasting, mobile phones, wireless Internet access, etc. is not affected (public instructions).
Therefore, everyone will treat this celestial phenomenon normally, and there is no ominous sign to come, it is just a normal astronomical wonder, look at it once less, and don't miss it.
Although it is the only total solar eclipse in 2021, people in most parts of the world cannot see this total solar eclipse, including China, which can only be observed in parts of Antarctica. Let everyone down, unless you are in the Antarctic region, it is impossible to see.
The next total solar eclipse will not occur until April 8, 2024, but the 2024 total solar eclipse will be seen in many regions, such as Canada, Mexico and parts of the United States.
If China wants to see the next total solar eclipse, and to see it well, it needs to wait until March 20, 2034 to occur in the mountainous areas of northern Tibet, but it is basically a no-man's land, and it also needs to be prepared in advance.
In addition, on September 2, 2035, there was another total solar eclipse in the north of China, with a duration of 1 minute and 29 seconds, this time is relatively good, so in terms of time, it will take 14 years for China to see a relatively perfect total solar eclipse, which is the general situation.
