Six people were sitting around the experimental group conference room of the School of Astronomy, Experimental Building, and Dean Li Huiqun.

"Today's regular meeting, I will introduce to you the new members of our team, Yuan Shichen." Li Huiqun continued after the introduction, "I guess you have heard that Yuan Shichen completed the four-year undergraduate teaching course in astrophysics in just one semester. This semester, we will conduct graduation thesis research in our experimental group. His research topic is to study the main components and evolution information of the solar system nebula through the detection of meteorite samples."

"I'm very happy to join the experimental group. Please take care of me with all my seniors." Yuan Shichen greeted everyone sincerely with a smile.

"Welcome, I am Ye Haijun, and my research direction is galaxy formation and gravitational lenses." A man in his early thirties first introduced that Ye Haijun is not tall, has a straight facial features and looks full of vitality. He is the most experienced member of the laboratory and the only doctoral student.

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

"Welcome, welcome, Senior Sister Qinglian said everything she should say, let's communicate more in the future." Liu Kun enthusiastically extended his hand to Yuan Shichen. Liu Kun was tall and could tell that he was an extrovert.

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

Later, when Yuan Shichen heard the introduction of others, she found out that her name was Chen Xi, and she was also a master's student in the experimental group. She was said to have a very good family background.

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

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

The people in the experimental group are usually busy with their own things. Because Yuan Shichen is a newcomer, Li Huiqun arranged for Lu Qinglian to give him some necessary guidance.

"This is where you usually do routine experiments and analysis. There are only some commonly used experimental equipment here. Some precision and high-end instruments, such as high-precision trace elements and isotope analysis equipment that you will use when performing meteorite detection, are managed by dedicated personnel. You need to apply and make an appointment in advance when using it." Lu Qinglian brought Yuan Shichen to a laboratory and introduced.

Yuan Shichen looked at the laboratory. The room was furnished in a simple manner. An ultra-high-definition electronic scanning microscope was placed on the laboratory bench.

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

"In the past few days, you must be familiar with our laboratories and commonly used equipment as soon as possible. If you encounter operating problems, you can ask me and Liu Kun. The equipment level and scientific research strength of the laboratory of Tsinghua University School of Astronomy are relatively good in China, and can basically meet our daily scientific research needs. However, if you need to use more top technical forces, you must apply to the Chinese Academy of Sciences - the most authoritative scientific research institution through the college. "Lu Qinglian introduced to Yuan Shichen seriously.

"By the way, the first batch of meteorite samples you need to test and study will be sent to the laboratory in a few days. You will go to the Materials Department to collect them at that time." Lu Qinglian added.

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

In the next few days, Yuan Shichen learned about his research tasks in detail.

This research project is actually a branch of a multi-national joint project, and it also carries out astronomical research experimental groups from well-known universities such as Harvard University in the United States, King's College in London, Munich Polytechnic University in Germany, Australian National University, and Tokyo University in Japan.

The entire joint project team will analyze meteorite samples collected from all over the world. The experimental group where Yuan Shichen is located is mainly responsible for analyzing and studying meteorite samples collected in China, and conducting preliminary summary and analysis of the collected data to submit them to more authoritative institutions for further scientific research purposes.

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

The laboratory is filled with more than 100 meteorite samples from all over the country that Yuan Shichen received from the Materials Department, most of which are stone meteorites, and a small number are iron meteorites.

Most of these meteorite samples have "melting shells". The molten shell is a thin shell formed by a meteorite flying at high altitude, with a surface temperature of several thousand degrees, and the surface melts into liquid. When the melted surface cools down.

Because meteorites often contain iron, the melted shell is usually black, but there are also brown or green, or even clearer colors.

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

In the next few days, Yuan Shichen basically stayed in the laboratory except for resting and going out to inquire about information.

With his amazing learning ability, he mastered all experimental theories and the operation of various equipment very quickly. During the process of conducting all major and small experiments, the operation of each link was like flowing, both accurately and in place, and never made any mistakes.

This made Lu Qinglian and Liu Kun in the next laboratory stunned and praised him for being watching an art performance.

On a sunny night, on a hill in the suburbs, there is a wide view.

A faint moonlight shines on the grass, and the singing of crickets rings everywhere in my ears. The fragrance of the night is spreading in the air, and many astronomical enthusiasts are gathering here to wait and watch the Gemini meteor shower.

Among these astronomy enthusiasts, there are the learning maniac Yuan Hakchen and his close friends in college.

"Wow, there are such professional astronomical telescopes, which is what it means to watch a meteor shower!" Wang Yali was excited.

"That's right, who made us from the Astronomy Academy? Watch the meteor shower with us..." Yang Yang boasted with pride.

Yuan Naichen and Deng Xiaochao have set up and debugged the astronomical telescope on the hills, and Zhang Xiaoming is carefully teaching Lu Qiufang how to use the astronomical telescope.

Chen Shuqin was sitting on a round rock and waiting quietly, looking forward to the stars from time to time.

Suddenly, cheers rang out in the crowd, and the meteor shower arrived as scheduled.

A meteor fell from the distant interstellar interstellar, like a bright ribbon, dancing into the deep night sky. Then several meteors passed through the sky, emitting charming brilliance, and melted into the night sky little by little.

The reason why meteors are beautiful is that they are brilliance at that moment, and the reason why meteors are beautiful is that they are passing by. Tonight, an expected meteor shower is so beautiful that it has a unique artistic conception.

"Xichen, the starry sky here is so beautiful. It is far away from the mist and escapes from the hustle and bustle. Looking at the endless night sky, this feeling is both peaceful and mysterious." Chen Shuqin still looked at the night sky from afar and said slowly to Yuan Xiaochen.

"Yes, every time I look at the starry sky, my heart becomes quiet. How shocking and awe-inspiring the starry sky is." Yuan Shichen glanced at Chen Shuqin and looked at the starry sky again.

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

Yuan Shichen also remembered his experience of looking at the starry sky at the pond where the origin of Sun and Moon Creek, and remembered the strange ore that unexpectedly encountered after the meteor that night, which completely changed his life trajectory.
