Good news! Approaching the end of October means that November is coming, not only is the long-awaited New Year's holiday one step closer, but the two long-awaited celestial phenomena for astronomy enthusiasts will also quietly arrive. In ancient times, observing celestial phenomena may have been a means of predicting auspiciousness and calculating agricultural time. Nowadays, it has become more and more common, becoming more and more "accessible". According to the official forecast, prepare the tools in advance, make time, and find the best observation point, you can take the lead in seeing it with your own eyes and solve the hunger.
<h1 class="pgc-h-arrow-right" data-track="5" > 2021 super "blood moon" is coming! What are the highlights of November? </h1>
According to the official forecast, on November 5, there will be a mysterious "Uranus Rush". This is a once-in-a-lifetime opportunity for veteran astronomy enthusiasts, and it is also a target for observation. In the past, perhaps Uranus was relatively far away from us, and most astronomical enthusiasts did not have the hard condition of observation equipment.
However, the opposition of Uranus this time is more peculiar, not only as usually thought to be a good opportunity to observe the mysterious planet of Uranus using the unique position where the earth is located, but also because the 5th Uranus opposition is visible all night, the brightness is as high as 5.7, visible to the naked eye. Only a SLR camera is needed, and even a mobile phone can capture this rare moment of "show strength".
Immediately after, it is the much-anticipated super "Blood Moon" in 2021! According to the official preview, it will be officially staged on November 19. The "Blood Moon" spectacle, also known as the partial lunar eclipse, has a food score of up to 0.978, which can be regarded as a total lunar eclipse. As the second lunar eclipse of the year, how is this time different? It is said that "the blood moon sees, the demon appears", as an ominous omen, is this really the case? How exactly does the Blood Moon happen? With these questions, the following is still a specific science popularization by the Rubik's Cube.
<h1 class="pgc-h-arrow-right" Data-track="40" How > "Blood Moon" is generated? Why is it called an ominous omen? </h1>
The blood moon, also known as the "tengu eats the moon", is scientifically called the lunar eclipse. When there is a lunar eclipse, if it is a partial lunar eclipse, it will show the spectacle of the moon in the sky missing a corner, and if it is a total lunar eclipse, it is a complete large moon, just like the Mid-Autumn Festival every year. However, the lunar eclipse is still a little different from the moon in the Mid-Autumn Festival, that is, there will be a "blood moon" during the lunar eclipse, and the moon in the sky is red. It is precisely because of its rarity that many people are prone to imagination only from the appearance.
The reason why the blood moon is red is because the thick atmosphere absorbs the purple, blue, green and yellow light, leaving only red to penetrate, so the red moon appears during the lunar eclipse. The formation of the blood moon is because the sun, the earth and the moon are just or almost in the same straight line, and the light from the sun to the moon will be partially or completely obscured by the earth, so a lunar eclipse occurs, thus presenting the scene of the blood moon.
So why is it called an ominous omen? There are two main reasons. First of all, judging from the appearance of the blood moon, it is indeed red, and in ancient times, it was extremely easy to associate with disasters and disasters without understanding so much scientific common sense. So there are many rumors in the folk, such as: "The blood moon is a fierce moon, it is a fierce omen", "The blood moon appears, the planet is broken, the qi is exhausted, such as falling into prison", "the red moon and even the yin to the cold phase, indicating that the world is weak in righteousness, evil is strong, resentment is strong, and the anger is strong; the wind and clouds change drastically, the mountains and rivers are mournful; the world is turbulent, and the fire is everywhere"... Wait a minute.
Secondly, in ancient times, there were many myths and stories, and the blood moon was only once or twice a year, which was indeed too rare. For example: Houyi Shooting Sun, Chang'e Jade Rabbit and so on. The moon is usually given a very important position, as one of the main objects of divination, and the slightest movement seems to represent something. The blood moon was also known in ancient times as the "tengu eating the moon", and they believed that the tengu would gradually eat the moon, and even people would not hang out outdoors when this celestial phenomenon occurred. Under the habit of the past for a long time, gradually the blood moon did not spread more and more evilly. Therefore, it is more verified that it is an ominous omen.

<h1 class="pgc-h-arrow-right" data-track="41" > what happened to the four blood moons? Will blood moon really demonize? </h1>
Four blood moons in a row, which means that there have been four total lunar eclipses for two consecutive years. The four consecutive blood moons are indeed more rare, and the blood moon that appeared in 2019 before 2021 is neither a continuous blood month nor a continuous total lunar eclipse. But it also exists, and NASA estimates that the next four blood moons will appear in 2032-2033.
It is worth noting that there have been four consecutive blood moons in history, only 3 times in 500 years, and the most recent one occurred in 2014. However, it is very surprising that it seems that every time it appears, there are indeed extraordinary things that happen in that year, so the rumor about "blood moon sees evil appears" is even more mysterious. For example, in 1493 and 1494, a series of four blood moons appeared, and the Spanish regime, the first country in history to be crowned the "Empire of the Sun Never Sets", was overthrown. In 1967 and 1968, another four blood moons in a row, the Third Middle East War occurred, causing hundreds of thousands of refugees to be displaced, and countless deaths and injuries... Wait a minute.
Are the rumors true? Not really! In fact, the Blood Moon and the disaster are completely unreliable, and there is no inevitable connection. The blood moon is only a natural phenomenon in essence, and the reason why it is associated with disasters is also because the ancients did not understand scientific principles, and had different beliefs, emphasized the unity of heaven and man, liked divination, and watched the sky at night. Today, astronomy has become independent and has become another major scientific category beyond man and nature. In the long history of mankind, disasters cannot be avoided, which are the natural evolution of people and the environment.
<h1 class="pgc-h-arrow-right" data-track="42" what are the highlights of the blood moon on the 11th of this month >? Where is the best observation point and when is the best observation time? </h1>
The blood moon on the 11th mainly has two highlights, first of all, as mentioned above, the food score is as high as 0.978, which can be regarded as another total lunar eclipse, and the super moon + red moon + total lunar eclipse group reappears, becoming a rare scene in history, so that the viewer can feast their eyes. In addition, there is another highlight that when the "eclipse moonrise" occurs, there will be as many as 3,000 or so clusters of stars near the moon. At that time, the 7 stars known as the "Seven Sisters Cluster" will be visible to the naked eye, and in ancient times, people also used this opportunity to test their eyesight. Generally speaking, people with good eyesight can still see more than 7, and we can also try it.
Well, here's the problem. Such a rare super blood moon, where is the best observation point? When is the best time to observe? Experts said that the coverage of the blood moon is very wide, in addition to the polar continents, other continents can be seen, mainly concentrated in the western and northwestern parts of the continents. As far as the ocean is concerned, the Pacific Ocean and the Arctic Ocean can also be seen. As far as China is concerned, because the original coverage has the whole of Asia, it is just located in the second half of the lunar eclipse, so it can see the "moonrise with eclipse" in its entirety, and it only needs to be suitable for combining the landscape to take a perfect photo.
In addition, in terms of observation time. The time of the appearance of the blood moon is relatively friendly, neither late at night nor in the early morning. Experts say the eclipse occurred at 17:02 p.m., when the whole process was just beginning, and the moon was just above the horizon. At that time, you only need to keep watching the east, and after more than an hour, that is, around 18:47, it will return to the circle. In fact, the observation time is different every year, and the duration is also different, so it is really rare to have such a long and suitable observation time.
<h1 class="pgc-h-arrow-right" data-track="43" > summary</h1>
Humans live on Earth, and the moon and earth are so closely related, as the new youth of the twenty-first century, it is crucial for us to understand the principle of the formation of the blood moon. It is reported that because the moon and the earth are indeed close, so when there is a lunar eclipse, it will have a relatively large impact on the earth's tides, but there is no scientific basis for the impact in other aspects, such as tsunamis, earthquakes, etc. are not necessarily possible.
All in all, the two major celestial phenomena of November are still not to be missed, especially what attracts attention in 2021 is another super blood moon spectacle. On the 19th, when the time came to move the small bench, it was time to see who could witness this historic moment. After all, after watching it this time, I am not sure if there will be next year!
