Shen Kuo, a scientist in the Northern Song Dynasty, once wrote such a passage in Meng Qian's Bi Tan, describing the scene when a meteorite fell to the ground: "... the sky thundered, but a Mars is like a moon, in the southeast. Occasionally, it will vibrate again and move to the southwest. Another earthquake struck Xu Shiyuan, a citizen of Yixing County. Look far and near, the fire is bright, and the fences in Xushi are burned out ... "Comparatively speaking, the way Jilin meteorites fall to the ground is much more magical.
Walking into the Jilin Meteorite Museum, just in time to explain. When you step into the exhibition hall, you are faced with a vaulted corridor wrapped by an electronic screen. Numerous galaxies passed by us, and the narrator introduced them one by one: "The Cat's Eye Nebula flew over us on the left, and the Butterfly Nebula was on the right ..." Just when we were too busy to look at it, we unconsciously came to a dome cinema. From the movies, I learned about the origin of the universe and the formation of meteorites. It turns out that meteorites are meteors wandering in the asteroid belt and other parts of the universe, or celestial bodies of different sizes. When they enter the gravity range of the earth, they will approach the earth. Some asteroids passed through the earth and flew away; But some fly directly to the earth, break through the atmosphere and fall into the sea or land. When it breaks through the atmosphere, the fast and large asteroids will burst under the blocking of the dense atmosphere and then hit the surface. This is how the Jilin meteorite came to us.
After watching the movie, we saw the largest stone meteorite in the world-"Jilin No.1 meteorite". It is a fragment separated from the "planetary bomb" that the universe rushed to the surface. But this so-called' fragment' actually weighs 1770 kg! Looking at this meteorite carefully, I saw that its appearance was uneven and brown-black, as if it were a weather-beaten old planet that had been hit by thousands of meteorites.
"Jilin No.1 Meteorite" is famous not only for its size, but also for its miracle when it fell!
As we all know, there are hundreds of fragments after the meteorite explosion. So after the explosion, debris flew in all directions, forming a meteorite shower with an area of over 500 square kilometers! Surprisingly, these meteorites seem to have an "automatic avoidance system" when they obviously hit inhabited villages, and there is no damage except the surface! If this is a shock to the people, it is a surprise to the scientific community! According to research, meteorites contain 34 known minerals and 9 minerals that are not found on the earth. This "whisper" has brought a major breakthrough in human exploration of the universe!
Visiting the "Jilin No.1 Meteorite" can't help but sigh the magic of the universe. A meteorite has given mankind a new understanding of the universe. If rocks are "books" that record the history of the earth, then meteorites are witnesses to the changes of the universe!
