In the experimental building of the School of Astronomy, there are six people sitting around in the conference room of Dean Li Huiqun's experimental group.

"At today's regular meeting, I would like to introduce to you a new member of our team, Yuan Chen." After Li Huiqun's introduction, he continued, "I think you have also heard that Yuan Haochen completed the four-year undergraduate teaching course in astrophysics in only one semester. This semester, he will be working on his graduation thesis in our experimental group, and his research topic is to study the main components and evolutionary information of nebulae in the solar system through the detection of meteorite samples. “

"I'm glad to join the experimental group, please take care of your brothers and sisters." Yuan Haochen greeted everyone sincerely with a smile. "Welcome, I'm Ye Haijun, and my research direction is galaxy formation and gravitational lensing." A man in his early thirties, who was in his early thirties, was the first to introduce that Ye Haijun was not tall, with good facial features and an energetic appearance, he was the most senior member of the laboratory, and he was the only doctoral student.

"Welcome, my name is Lu Qinglian." A girl with a smile on her face immediately spoke, "He is Liu Kun, the two of us are in the same graduate research group, and our research direction is planetary orbits." “

"Welcome, welcome, Senior Sister Qinglian has said it, let's communicate more in the future." Liu Kun enthusiastically stretched out his hand to Yuan Haochen and said, Liu Kun is tall, and it can be seen that he is an extrovert.

"Welcome." A beautiful girl waited until everyone else finished speaking, and then spit out two words with a cold face.

Later, Yuan Haochen learned from other people's introductions that her name is Chen Xi, and she is also a master's student in the experimental group, and it is said that her family background is very good.

"Okay, I hope everyone will get along in harmony in the future, help each other, and make progress together!" Li Huiqun said loudly.

Next, the members of the experimental group need to report the research progress of each research group to Dean Li as usual, and Dean Li will comment and guide everyone's research work.

The people in the experimental group are usually busy, because Yuan Haochen is a newcomer, so Li Huiqun arranged for Lu Qinglian to give him some necessary guidance.

"This is where you usually do routine experimental analysis, and there are only some commonly used experimental equipment here. Some precision high-end instruments and equipment, such as the high-precision trace element and isotope analysis instruments and equipment that you will use when doing meteorite detection, are managed by special personnel, and you need to apply and make an appointment in advance when using them. Lu Qinglian took Yuan Haochen to a laboratory and introduced.

Yuan Haochen looked at the laboratory, the room was simply furnished, and an ultra-high-definition electron scanning microscope was placed on the laboratory table.

There is also an electron probe device, an isotope analyzer, X-ray fluorescence spectrometer around the test bench, and a glass-door cabinet against the wall, which is filled with various glass instruments and medicines.

"In the past few days, you have to familiarize yourself with our laboratory and common equipment as soon as possible, and if you encounter operational problems, you can ask me and Liu Kun. The level of instruments and equipment and scientific research strength of the laboratory of the School of Astronomy of Tsinghua University are relatively good in China, which can basically meet our daily scientific research needs, but if we need to use more top-notch technical strength, we must apply to the Chinese Academy of Sciences, the most authoritative scientific research institution, through the college. Lu Qinglian seriously introduced to Yuan Haochen.

"By the way, the first meteorite samples you need to test and study will be sent to the laboratory in a few days, and you will have to go to the materials department to collect them then." Lu Qinglian added.

"Okay, thank you, senior sister, I will start getting familiar with the work as soon as possible." It seems that this senior sister is still quite enthusiastic, and Yuan Haochen hurriedly thanked Lu Qinglian sincerely

In the next few days, Yuan learned more about his research mission.

This research project is actually a branch of a multinational joint project, which is carried out at the same time by the astronomical research experimental groups of well-known universities such as Harvard University in the United States, King's College London in the United Kingdom, Technical University of Munich in Germany, Australian National University, and the University of Tokyo in Japan.

The entire joint project team will analyze meteorite samples collected from around the world. Yuan's experimental group is mainly responsible for analyzing and studying the meteorite samples collected in China, and conducting preliminary summary analysis of the collected data for submission to more authoritative institutions for further scientific research purposes.

Specifically, Yuan needs to analyze the physical, optical, mechanical, and structural properties of various meteorite samples.

The laboratory was already full of more than 100 meteorite samples from all over the world that Yuan Haochen had received from the materials department, most of which were stone meteorites and a small number were iron meteorites.

Most of these meteorite samples have "molten shells". Molten crust is a thin crust formed when the surface temperature of a meteorite reaches several thousand degrees when it flies at high altitude, and the surface melts into a liquid, and when the melted surface cools down.

Because meteorites often contain iron, molten crusts are usually black, but they can also be brown or green, or even more clearly colored.

Yuan also found that a very small number of meteorite samples did not have molten shells, and they looked as ordinary rocks. This is because the meteorite fell to the earth for a long time, and the molten crust weathered and peeled off.

In the next few days, Yuan Haochen basically soaked in the laboratory except for rest and going out to inquire about information.

With his amazing learning ability, he mastered all the experimental theories and the operation of various equipment very quickly. In the process of conducting all the big and small tests, the operation of each link is like a smooth flow, that is, accurate and in place, and there has never been a mistake.

This made Lu Qinglian and Liu Kun in the laboratory next door stunned, and they praised that this was simply watching an art performance

On a sunny night, on a hill with a wide view on the outskirts.

The faint moonlight shone on the grass, and the song of crickets rang in my ears. The scent of night fills the air, and astronomy enthusiasts are gathering here to watch the Geminid meteor shower.

Among these astronomy enthusiasts are the study madman Yuan Haochen and his best friends from college.

"Wow, there is such a professional astronomical telescope, this is called watching meteor showers!" Wang Yali jumped with great interest.

"That's, who made us from the Academy of Astronomy and watch the meteor shower with us," Yang Yang boasted proudly.

Yuan Haochen and Deng Xiaochao have already set up and adjusted the astronomical telescope on the hill, and Zhang Xiaoming is carefully teaching Lu Qiufang how to use the astronomical telescope.

Chen Shuqin was sitting on a round rock waiting quietly at this time, looking up at the starry sky from time to time.

Suddenly, there were bursts of cheers from the crowd, and the meteor shower arrived as scheduled.

A meteor, drawn from the distant stars, danced into the deep night sky like a bright ribbon. Immediately after that, several meteors streaked across the sky, emitting a mesmerizing brilliance that melted into the night sky little by little.

The reason why the meteor is beautiful is the brilliance of that moment, and the reason why the meteor is beautiful is the beauty of the moment when it passes. Tonight, an exciting meteor shower is so beautiful that it has a unique artistic conception.

"Hao Chen, the starry sky here is so beautiful, away from the fog, escape from the hustle and bustle, looking at the endless night sky, this feeling is peaceful and mysterious." Chen Shuqin was still looking at the night sky from afar, and said slowly to Yuan Haochen.

"Yes, every time I look at the starry sky, my heart becomes peaceful, how shocking and awe-inspiring the starry sky is." Yuan Haochen glanced at Chen Shuqin, and then looked at the starry sky in the distance.

"I think of the night sky in Hanhai City, which is quieter and clearer than here," Chen Shuqin said with emotion.

Yuan Haochen also remembered his experience of looking at the starry sky by the waterhole at the source of Sun Moon Creek, and remembered the strange ore that he encountered unexpectedly after the meteor that night, which completely changed the trajectory of his life.

Yes, maybe I can start trying to learn more about that piece of ore, and I can use the equipment in the laboratory to analyze its composition, Yuan Haochen thought to himself
