As we all know, in ancient times, if there were celestial phenomena such as "tengu eating the moon" and solar eclipses, many people would think that it was a bad omen, because at that time, everyone did not know why the moon suddenly fell shorter, and did not understand how the sun was suddenly covered and became dark.
And meteors are different, the ancients made a wish to a shooting star, that is a common thing, whether it was in the past, or today, everyone regards it as a romantic and beautiful astronomical phenomenon, even if you already know that it is useless to make a wish for a meteor, but if you can see the meteor from the sky, it will still be exciting and exciting.
Of course, meteors are also more common than the tengu eating the moon, such as the Gemini meteor shower between December 4 and 17 every year, and at great times you have a chance to see 150. However, the Gemini meteor shower is not formed after the comet enters our Earth's atmosphere, because its parent body is actually an asteroid 3200, the foreign name translates to "Faretong", it is obvious that this asteroid is unusual, which can be seen from its orbit, in the currently named asteroid, asteroid 3200 is the one closer to the sun, until 1983 when scientists discovered its existence, Only at that time it had a temporary name called 1983 TB.
No, the glass of the Jinan Seven Star Observatory was smashed, and there was a Gemini meteor shower that night, and when astronomy enthusiasts went here to see the meteors, they accidentally found that the glass of the Stargazing House was broken, and the time was 8:30 p.m. on the 13th. In fact, on the first night, when the staff walked down the stairs after the cleaning work, they did hear an abnormal noise, which sounded like the sound of glass breaking, but at that time, the staff only looked at the glass on the first floor, and there was no new glass stargazing house.
The staff also said that this glass stargazing house has not been used for the time being because it has just been painted with floor paint, and it is afraid that the time to dry is not enough to step on it, and the door has always been locked.
Niu Guihua is the head of the Seven Star Observatory, but also the president of the Jinan Astronomical Amateurs Association, on the night of the 13th, he plans to broadcast this meteor shower to everyone, so that everyone can witness the beauty together, but the power supply should be taken out of the glass stargazing house, so the door of this room is opened, but even if there is no light in the house, but when he opens it with a flashlight, he finds that there is broken glass on the ground, to know that it is tempered glass, according to the reason, it will not suddenly break into slag.
Therefore, Niu Guihua retrieved the surveillance footage of the night, and the surveillance video showed:
At 00:04:44, there was a white thing smashing into the glass on the roof, and there were two different sounds, one was the sound of an unknown object hitting the glass, and the other was the sound of the sound shattering. On the other hand, there is a 12 mm steel column next to the glass stargazing house, and from the surveillance screen, the diameter of this unknown object should be smaller than the diameter of the steel bar next to it.
When this matter was first known, there was also speculation about whether the tempered glass would explode itself, or that ice would fall from the plane and then just hit the tempered glass, rather than a meteorite that did not burn out?
First of all, talk about the possibility of tempered glass self-explosion, Niu Guihua said that extremely cold weather is indeed possible to cause tempered glass to explode, however, this glass observatory has 4 pieces of glass, but only one piece of self-explosion, and, the temperature that night did not reach minus zero, to know that last winter experienced -30 ° C ultra-low temperature did not self-detonate, moreover, the tempered glass of this glass observatory has taken special measures when it is safe, that is, the use of elastic sponge, which allows it to have more telescopic space, Reduce the probability of self-detonation of tempered glass to a greater extent.
As for the speculation that the ice fell on the plane, it just happened that there was another route in this place, and the staff also consulted the "Jinan Air Traffic Control" department, but the current aircraft toilet is different from many years ago, and has long been improved to a sealed state, that is, the pipes on the aircraft are closed. Moreover, Niu Guihua said that the unknown object displayed in the monitoring, if it is really an ice cube, the size is not easy to break the tempered glass from a 45-degree angle, as for human and animal factors, Niu Guihua also said that it can basically be ruled out.
That is to say, the Jinan Seven Star Observatory was smashed by an unknown object to smash the glass, the current main suspect is indeed a meteorite, but it is not certain that it is really a meteorite, because, so far, no suspicious substances have been found, and this glass stargazing room was also closed at 9 o'clock in the evening on the 13th, and it is still waiting for relevant experts to identify it in more detail.
If the suspicious object is relatively easy to find in the house, but if it falls to the stone mountain road next to it, it is really difficult to find!
