In the evening, the source of the Sun Moon Creek, the soft sunset, and the brilliant clouds seem to lie on the mountains not far away, and at the foot of the mountains are a cluster of villages leaning on the mountains and rivers.

The sunset and the mist of the stream in the sky are intertwined, and the surrounding scenery gradually fades away from a haze.

Looking out at the tranquil foothills, the lush trees on the mountain seem to be covered with a halo of light. A clear stream meanders down the mountain, the stream slowly laps on the rocks, the smooth pebbles in the stream are clearly visible, the high mountain clouds in the sunset are also reflected in it, and there is a quaint small stone bridge over the stream, everything looks so simple.

Yuan Haochen walked across the small stone bridge and reached the front part of the village, and the extremely familiar buildings quickly came into view. Mother was already waiting at the door with a sweet smile.

Although Yuan Haochen also left home to live alone in high school, relatively speaking, the time of each departure was short and the distance was close.

In the past six months of studying at Tsinghua University, he has deeply realized the longing for his relatives in a foreign country.

Therefore, the moment he stepped into the house and saw his parents, his heart instantly overflowed with indescribable warm feelings.

Under the warm lighting, a table of delicacies carefully prepared by my mother was placed. During the dinner banquet, the parents, who are not good at words, only smiled, listening to Yuan Haochen tell the story of what happened at school in the past six months and what they had seen in the school, and bursts of joyful laughter wafted in the room from time to time

As the night wore on, Yuan Haochen rummaged through the bookcase in his room to find the strange ores that he had properly stored before.

Yuan Haochen understands that he does not have the ability to unravel the mystery of this ore at present.

But he is always trying to improve his ability and cognitive level, and I believe that there will be a day when the clouds and the moon will be cleared up.

In the next semester, he will be able to choose Dean Li's research topic as his graduation thesis, which means that he will have the opportunity to use the technical equipment of the university's scientific research laboratory to analyze and study this strange ore.

Thinking of this, he who has always been calm can't help but be a little excited.

So Yuan Haochen carefully put away the ore and put it in the suitcase that he was about to take back to school

During this time at home, Yuan Haochen basically accompanied his parents to be busy in the green vegetable base at home every day, and he knew in his heart that as he went farther and farther, he would spend less and less time with his parents in the future, so he especially cherished every minute with his family.

During this period, Yuan Haochen also participated in several reunions of high school classmates and met Fang Xiaoyu and Wang Sanke, who had not seen each other for a long time. Fang Xiaoyu met a female classmate at school, and then the relationship between the two quickly warmed up and became an extremely greasy couple. And this winter vacation, Fang Xiaoyu also invited her to come to Hanhai City to play, Yuan Haochen has also met several times, she is a very gentle and sweet girl. Wang Sanke has traveled all over the natural scenery of northwest China in the past six months, and now it seems that people have become much more arrogant and rough, and it really verifies the sentence, it is better to read thousands of books than to travel thousands of miles.

Soon, the pleasant holiday and the Spring Festival passed, and Yuan Haochen embarked on the journey back to school.

Because Chen Shuqin traveled with her family during the winter vacation for the Spring Festival, and then returned to school directly, Yuan Haochen returned to Beijing alone this time

The new semester began soon in a step-by-step manner, and the teachers and students of the School of Astronomy were widely discussing the matter of Yuan Haochen.

A freshman passed almost all the planned four-year course assessments in the last semester with perfect marks and received the corresponding credits. This semester, I will start to do my graduation thesis research with the dean in advance.

In the dormitory, Zhang Xiaoming was shouting: "Hao Chen, it's really amazing, we used to be considered academic bullies in school, but now compared with you, we are like scumbags, and we are ashamed of ourselves!" ”

"Don't you look at how diligent people are, it's like you are immersed in the gentle township every day." Yang Yang joked about Zhang Xiaoming and Lu Qiufang on the side.

Super Gongzi sat in his chair and didn't say anything, just turned his head and gave a thumbs up to Yuan Haochen.

"It's nothing, it's just that everyone is interested in different aspects" Just as Yuan Haochen explained in a routine, a pillow flew towards him.

"Let you pretend to be forced ~ Please eat at night." The crowd laughed and laughed.

Dean Li is a doctoral supervisor in the School of Astronomy, and originally rarely taught undergraduate dissertation topics. However, Dean Li's laboratory happened to have a topic on the interdisciplinary combination of meteorite and astrochemistry this year, which is suitable for undergraduate students as the research topic for graduation thesis.

Therefore, this project naturally fell to Yuan Haochen.

Yuan's main task is to analyze and detect meteorites collected from all over the world, and then study the main components, evolution, formation and other main information of the nebulae of the solar system.

Yuan Haochen had already dabbled in a lot of books about meteorites last year, so he was extremely familiar with them.

Meteorites are unburned stony, iron, or mixed stony-iron materials that are scattered on the surface of the Earth or other planets by cosmic meteors or dust fragments that have left their original orbits outside the Earth.

Meteorites come in a variety of shapes, and more than 40,000 meteorite samples have been collected around the world, which can be broadly divided into three categories: stony meteorites, iron meteorites, and stony-iron meteorites.

The largest meteorite found in the world so far came from China, weighing 1,770 kilograms, and the largest meteorite was the Goba meteorite from Namibia, weighing about 60 tons.

Most of the meteorites on Earth come from the asteroid belt between Mars and Jupiter, and a small part from the Moon and Mars.

Over the years, astroscientists have discovered that there is an asteroid belt between the orbits of the planets of the solar system, Mars and Jupiter, which is the home of meteorites.

Our planet receives 50,000 tons of such a "gift" every day.

Of course, most meteorites burn up at a height of 10 to 40 miles above the ground, and even if they fall to the ground, they are difficult to find.

Because meteorites have no other protection in the process of operating in the universe, they are directly exposed to radiation and catastrophe from various cosmic rays, so meteorites record a lot of reliable and valuable information. It has important scientific research value in the fields of high-energy physics, astronomical evolution, geochemistry, and the origin of life in astronomy.
