I wanted to write an article about some special astronomical phenomena that appeared two weeks ago, but I missed it because of a task. Let’s explain it again now, it can be regarded as a delayed echo. This is where some very magnificent astronomical phenomena appeared in the west. Why do you say it is magnificent? This is because in the sky around 20 o'clock at night, a very large area of light-band cloud suddenly appeared, and this light-band cloud was moving significantly and rapidly. The scope itself is very large. If the ground houses are used as reference, the background range of this fast-moving light-band cloud is even larger than that of the low-rise residence itself, which means there is a very large viewing area in the air at night. More importantly, like Comet , it moves quickly with a front point core. Its overall shape is a bit like a comet, but its radiation points are much sharper than those of comets; and the light-belt clouds spread farther than those of comets. If you pay attention to astronomy, you will know that Halley's comet has recently returned to orbit near the earth. Because 's comet tail is too small and thin,
is basically impossible to see directly with the naked eye on the earth, and can only be observed with a telescope of a certain multiple. The largest and brightest comet that humans can see on Earth in the past 30 years is the Haier Pop Comet that appeared from 1996 to 1997, but when it appears most obvious in the sky on the west side, it is only not much longer than the length of a full moon. The light-band cloud that suddenly appeared this time occupies a larger perspective in the sky than the house on the ground, which is quite extraordinary. More importantly, all comets move very slowly in the sky background, and the movement can basically be seen by the human eye alone. Only by observing at the same time every day will you find that you have moved slightly in the background sky. This shows that comets are all celestial phenomena that are hundreds of millions of kilometers away from the Earth. Therefore, the human eye looks small and cannot be seen even if it moves instantly. The light-band cloud that appeared this time had a very large observation range, and it was visible to the naked eye to move quickly.
finally took only ten minutes to fly across most of the sky. The shiny light-belt cloud eventually faded after a few dozen minutes and eventually disappeared. From these special features, this is obviously not a natural comet. The sudden appearance, the range is very large and the movement speed is very fast, which means that this is a high-speed flying object very close to the earth's ground, rather than a comet-like celestial body that is often hundreds of millions of kilometers away. Since this scattering cloud looks very much like the lighting area effect that appears when a vehicle turns on the high beam on the ground, some people say that this is the alien spacecraft suddenly turned on the high beam when it is approaching the earth. This is of course a joke, and the probability of such a situation actually happening is slim. Then it is neither a comet nor an alien to turn on the high beam. So what is this? In fact, it is very simple. It is the rocket of humans and the large rocket , which is mainly liquid power. When it just broke through the atmosphere and continued to climb eastward outside the atmosphere, the total reflection optical phenomenon observed by the rocket jet tail feathers under the rocket trajectory, which was observed by the rocket jet tail feathers under the special angle of sunlight. So large rockets are launched almost every day around the world. Why is this special astronomical phenomenon not very common? This mainly lies in the fact that there are several prerequisites for the formation of this special astronomical phenomenon. It's like it's raining almost all the time on Earth, but the probability of a rainbow appearing after the rain is not particularly high. Because whether it is the formation of a rainbow or the magnificent astronomical phenomenon that the artificial rocket flies, there are some necessary formation conditions. The first is that the observer must be roughly below the trajectory of the big rocket's eastward flight. Moreover, there is a distance of two or three thousand kilometers between it and the rocket launch point. Only at this distance has the large rocket launched by humans broken away from the 160-kilometer-thick atmosphere and began to continue climbing and flying outside the atmosphere. Second, the rocket's launch must be launched before and after sunset at the launch point. When the track passed the top of the observation square head on the east side, local time,
was already 1 to 2 hours after sunset, that is, between 19:00 and 20:00 pm.At this time, the location where the observer was located was completely dark. However, because the large rocket flying here is about 200 kilometers at an altitude, its jet tail feather can be strongly reflected by the sunlight at high altitudes, so it can see a spectacular high-altitude reflective cloud belt on the ground below the trajectory, and it will continue to move and spread as the rocket continues to fly. So the normal flight trajectory of the big rocket in the sky is just an arc, so why is the reflective cloud belt so huge? This is because the atmospheric pressure of space above 160 kilometers is almost zero, and the wake sprayed by liquid rockets is high-speed and high-pressure. The jet of liquid rockets will actually quickly spread out some extremely small water droplets in the vacuum. The longitudinal length will extend one or two thousand kilometers and hundreds of kilometers in the horizontal direction. Therefore, the range of this space cloud belt is very huge, and it looks naturally very spectacular on the ground. This rocket tail,
appears very suddenly, and disappears very quickly. The main reason is that the small droplets can only last for a few minutes in a space vacuum environment and completely evaporate. Moreover, as the earth rotates rapidly, the irradiation angle of the high-altitude sunlight will also change rapidly, and the appropriate total reflection phenomenon cannot be maintained for a long time. After this astronomical phenomenon appeared, G's statement was not abnormal, which implies that the rocket that produced strong reflection was not launched by its own country. It was later proved to be a special astronomical phenomenon produced by the large rocket launched by the famous Baikonur launch site abroad. Because the longitude of the Baikonur launch site is 63 degrees east longitude and 43 degrees north latitude, the manned rocket it launches needs to fly southeast, and the flight projection extends 1,500 to 2,500 kilometers after takeoff, just above some western regions. If the launch time is in the evening and the lighting conditions are appropriate, this kind of special phenomenon is more likely to occur.
