On the evening of November 8, 2022, the astronomical wonder " Blood Moon " will be staged soon. The blood moon usually appears at the same time as the total eclipse of in the month, which means that you can see two astronomical wonders of the total eclipse of blood moon and the total eclipse of lunar eclipse at one time. And this time, there is another even rarer surprise, that is, "Moon Covering Uranus". Three wonders of appear together, and it will be difficult to see again after missing this time. In ancient times, it was very afraid of the Blood Moon. It looked very strange and was considered an unknown sign. So how did the Blood Moon come about?
Magical Sun and Moon Wonder
Like the sun, the moon is one of the stars with the greatest impact on the earth. Since ancient times, the sun and the moon have been the object of worship by humans, but when various strange phenomena appear in the sun and the moon, they will also cause panic. solar eclipse and lunar eclipse are the two most common sun and moon phenomena, and these two have been given many myths. The more famous ones are Houyi shooting the sun and Chang'e running to the moon. In my country, solar eclipses and lunar eclipses are also called "Tiangou Food Day" and "Tiangou Food Day". According to , it is said that it is a fierce Tiangou chases the sun and the moon to vent its anger, and after catching up, it swallows it in one bite.
Without the sun and the moon, people will find it difficult to survive. So whenever there are solar and lunar eclipses, people will beat drums and gongs and set off firecrackers. The Tiangou can't stand the fright and will spit out the sun and the moon. Of course these are just folk legends. In fact, our country has studied solar and lunar eclipses a long time ago.
As early as 1217 BC, my country had records of lunar eclipses, which have been around for thousands of years. Later, various dynasties also recorded detailed records of solar eclipses. The sun gives life to all things, so solar eclipses are a bad omen in people's eyes, and the same is true for the lunar eclipse at this point. The solar eclipse is because the moon runs to the center of the earth and the sun, blocking part of the light shining on the earth, and it looks like the sun has been "eated". The lunar eclipse is because the moon runs into the shadow "behind the earth". Because the moon itself does not glow, the place blocked by the shadow of the earth seems to disappear. Some of the blocking is the html partial eclipse of lunar 3, and if it is blocked, it is the total lunar eclipse.
There are four types of solar eclipse when it occurs, namely daily partial eclipse , total eclipse , angular solar eclipse and total annular solar eclipse. There are three types of lunar eclipse when occur, namely partial eclipse, total lunar eclipse and penumbra lunar eclipse . html April total eclipse and partial lunar eclipse are easy to understand, so what is a penumbra lunar eclipse?
Because the earth is also an opaque sphere, part of the light from the sun will be blocked after it reaches the earth, creating shadows on the other side, which is why day and night occur. The earth shadow will be divided into umbiography and penumbiography. It can be simply understood that some light passes through, and the half-light and half-dark place is the penumbiography area. The lunar eclipse that the moon in the penumbra is called a penumbra lunar eclipse. Because the penumbra is still passing through the light, the moon just looks a little dimmer than usual and is not completely blocked.
When a total lunar eclipse occurs, it will also be accompanied by a very rare wonder, which is the "blood moon" that is considered an ominous omen. As the name suggests, the blood moon refers to the red moon. Among the people, the blood moon is the "bad moon" and "evil moon" of . Once appears, bad things will happen. In Western legends, all kinds of evil ghosts will also gain powerful power when the blood moon occurs, so there is a custom of not going out of the house. So how did the blood moon, which is so scary? The appearance of the blood-moon phenomenon is mainly because the earth's atmosphere refracts part of the sun's rays to the moon in total eclipse, thus casting the moon with a "red" veil. Why is it red? Because the penetration of red light is stronger.Most of the light of other colors such as purple, blue, green is absorbed by the atmosphere, but some of the red can reach the moon. Therefore, when we look at the moon, it is reddish colors such as red or orange red.
The ancients divided the process of lunar eclipse into several processes. The initial loss represents the beginning of a lunar eclipse. Eclipse means that the moon has completely run into the shadow of the earth. Even the moon is located in the middle of the earth's shadow. This is also the most obvious and beautiful time of the blood moon. The birth of light means that the lunar eclipse gradually ends and the moon begins to return to its normal appearance. Rerounding means that the moon is fully restored and the entire lunar eclipse process ends.
During the lunar eclipse, there will be two stages: penumbra eclipse and penumbra eclipse end. At this time, the moon has begun to slowly dim, but it is difficult to find without careful observation. The initial loss of this total lunar eclipse occurred at 17:09 on the evening of November 8, edema edema edema at 18:59, and edema edema at 20:49. The whole process lasted for a relatively long time.
The special thing about this total lunar eclipse is that the moon covers Uranus. Uranus ranks seventh among the eight planets in the solar system and third in size. Uranus is relatively dull, but it is still visible on Earth, so when the moon orbits the earth, it slowly blocks Uranus. This phenomenon is called "Moon covers Uranus". can be seen during this lunar eclipse. In addition to Uranus, the phenomenon of html occultation in in February also occurs. For example, Venus, Jupiter , Mars Saturn, etc. can all be blocked by the moon. The lunar eclipse that occurred on
8 can be seen in most parts of my country, especially in the eastern region. Only when the weather is good can you see the whole process. Although the Blood Moon looks weird, people now only regard it as a rare astronomical phenomenon, so there is no unknown, and you can watch it with confidence.
