There are traces of the galaxy

The walls and ceiling around Li Zhi's room are pure black, and the lighting is very dark, cold, with a faint dark blue, forming a strong contrast with the outside.The living room is decorated in warm colors, most of the furniture is made of mahogany, and the decoration is rather simple. Opening the door of Li Zhi's room, it seems that you have suddenly fallen into a different space, as if you were still in the wooden house in the mountain one second, and you have traveled through it in the next second. Into the world of science fiction.

"It's so cool." Lin Chaosheng said in surprise as soon as he entered the door.

"It's okay," Li Zhi bent down, opened the small refrigerator at the foot of the table, "Would you like a drink?" He took out two cans of red Coke.

"Thank you," Lin Chaosheng took the Coke and pulled the tab with a snap. "When I was a child, I also thought about painting the room black. I told my mother about this idea, and she scolded me."

"Hahaha, if my mother would definitely scold me." Li Zhi also opened the Coke, and the carbon dioxide gas gushed out frantically.

Lin Chaosheng's eyes moved away from the miniature green refrigerator.Li Zhi's room is large, but there are not many things, and they are arranged in an orderly manner, which looks a bit empty.

Except for the bed, the big guy standing on the balcony-a white refracting telescope, Lin Chaosheng noticed as soon as he entered the door, there are several black wires of different thickness at the interface connected to the computer host.

There is a gray iron bookcase on the right side of the balcony, with a metallic texture and a cool air.

The upper layer of the bookcase is full of books by category, and the lower layer has a glass compartment, which is filled with all kinds of strangely shaped big stones. There is nothing special about it, but they must be Li Zhi's cherished collection.

Lin Chaosheng glanced roughly at the upper shelf of the bookcase. Several books caught his attention, including Introduction to Astronomy, Modern Astronomy, General Astronomy, and some books related to physics.

"Are you studying astronomy?" Lin Chaosheng asked curiously.

Almost everyone who is good at science and full of curiosity has dreamed of being a parent, and Lin Chaosheng is no exception.His dream of being an astronomer was shattered at the age of 13. There was a telescope store in Qimao City where his father worked. He passed by and was attracted by the variety of equipment in the window, and glimpsed the instrument introduction and price list.American Celestron, Reflective, 3500.At that time, Lin Jingye was working part-time in an auto repair shop, and his monthly salary was only more than 3000. He took a look outside the window and left silently.Later... Later Lin Chaosheng forgot about it.

"Now it's physics for my undergraduate degree." Li Zhi thought for a while and replied, "Those are the textbooks I read in my undergraduate course, and I don't want to throw them away."

Lin Chaosheng asked hesitantly, "Aren't you an undergraduate student?" He felt that Li Zhi was about the same age as him, and he seemed to be a sophomore or junior at most.

"Do I look so young?" The corners of Li Zhi's mouth curled up, "I'm in graduate school at the beginning of school."

Lin Chaosheng let out an "oh", but was a little surprised in his heart.I really can't tell.

In fact, Lin Chaosheng also thought about applying to the Department of Astronomy when he was filling out his application a few days ago, but he just thought about it.I'm a little interested, but not to the extent that I have to learn, after all, the universe is too far away from him.

Li Zhi took two sips and put the Coke on the computer desk.Lin Chaosheng followed Li Zhi's hand holding the Coke can, and saw the camera placed on the black table, as well as the equatorial mount and theodolite placed beside the table. He himself can only be regarded as a half-hearted astronomer. He couldn't recognize such a sophisticated instrument.

"Do you play astrophotography?"

"No," Li Zhi shook his head, and picked up the camera, "I bought this and it didn't work much. I tried it, but it didn't work."

In recent years, the development momentum of the electronic technology industry has been strong. Large-aperture and wide-angle lenses have become cheap. Generally, wealthy enthusiasts can afford them, and those with little money can buy them with savings. Taking pictures of star trails and galaxies has become very simple. In the photos, the universe is no longer as far away as it was before the advent of the information age.

Li Zhi has photographed star trails and the Milky Way, and the experience is complete.There are too many people taking pictures of these things now, and Li Zhi doesn’t have any unique attainments in this area. If you want to appreciate photos, you can search them online. Professional photographers take much better photos than him.

So he started to try deep space photography and take pictures of nebulae, but the results were always unsatisfactory.Shooting deep space requires extended exposure, which is time-consuming and labor-intensive. It is often taken from late at night to dawn, and the nebula in the original material is blurred, with only a little faint light. It requires complex post-processing to make a colorful nebula image. .Sometimes if something goes wrong in any link, the computer will be completely blank, and all the energy of the night will be in vain.

Li Zhi thought it was too troublesome, so he didn't continue to shoot, and the equipment was basically idle. Occasionally, his cousin Dai Yueran came to live here on vacation, and let her tinker with it by herself.

Near noon, it really rained outside, pattering down for a while, and the sky cleared up soon.It seems that Li Zhi and Li Wenjin were right.

"Do you think it will rain tonight?" Li Zhi sorted out the materials for the start of school at the computer desk.

Lin Chaosheng was sitting on the small sofa on the balcony, looking at the introductory stargazing guide that Li Zhi gave him from the bookcase. Hearing this, he glanced at the sky outside, "I guess not."

"I don't think so. Although there is no meteor shower, there are still many stars, and maybe the Milky Way." Li Zhi paused, "Do you want to see it?"

Li Zhi is a person who is afraid of trouble, but he is unexpectedly patient with Lin Chaosheng.Li Zhi was not so enthusiastic, but looking at Lin Chaosheng who was sitting on the balcony and looking at the stargazing guide seriously, he suddenly wanted to invite him to watch the stars.

One is because Lin Chaosheng is polite and sensible, and he didn't ask to play with the telescope or touch the instrument, and the other is maybe because Lin Chao looks good-looking, and people always have a little more patience with good-looking people.

"Okay, where to look?"

Li Zhi never said the answer to this question. He just told Lin Chaosheng when he asked, and you will know it at night.

The afternoon passed quickly, and night fell quietly.

After a simple dinner, Li Zhi took out a few cans of green beer from the small refrigerator and let Lin Chaosheng hold him. He opened the drawer under the computer desk, bent over slightly, and rummaged through something.

"found it."

Lin Chaosheng took a closer look and saw that Li Zhi was holding a portable pair of binoculars.

Li Zhi pointed to the telescope on the balcony, "It's too troublesome to move that up, but this is enough to see it."

Li Zhi asked again: "Can you use a camera?"

"No." Lin Chaosheng held the cold beer, his hands and clothes were wet, but he didn't feel very cold.

"I teach you?"

"Don't bother." Lin Chaosheng said hurriedly, he is really not good at taking pictures, and he might screw up.

"Okay," Li Zhi blinked, looking a little frustrated, but he quickly took out his phone, "There is no light pollution here, and you can take pictures with your phone."

"Really? I don't know why, but the photos I take with my mobile phone are always blurry." Lin Chaosheng's mobile phone is a model from last year, and the pixels are quite high, but no matter what he takes, the picture is blurry. This is definitely not the reason for the pixels. .

Li Zhi turned on the camera, leaned in front of him, and taught him, "Adjust the exposure time of the phone to a longer time, increase the ISO, and just fix it in one place. You can try it later."

"...Okay." The distance between the two was very close. Li Zhi lowered his head. From Lin Chaosheng's angle, he could just see the swirls hidden in his black hair and a small section of white hair exposed from the collar of his T-shirt. neck.Lin Chaosheng was not used to being so close to others, so he slightly turned his body back.

Lin Chaosheng held five cans of beer in his arms and followed Li Zhi from the dark room to the dark stairwell. The voice-activated light was very sensitive, and it would light up with a light stomp.The two climbed up to the third floor, the roof was separated from the inside by a glass door, and a red lock was put on the door handle.

Lin Chaosheng was a little surprised: "Why is it still locked?"

"Hmm..." Li Zhi took out the key from his pocket and said as he unlocked it, "I'm afraid someone will commit suicide and jump off the building. There are quite a few people who come to my house to stay overnight. Sometimes... you know."

"Understood." Lin Chaosheng nodded. In fact, he didn't understand very well, but he didn't ask any questions. His intuition told him what should have happened here.

Push open the glass door and walk to the roof. The night sky is not blocked by any buildings, and a large amount of starlight shines down, making the roof look very bright.

Lin Chaosheng looked up, the sky was as black as splashed ink, with a touch of blue, and the sky was full of stars, which was unbelievably beautiful.No matter how high-end the lens is, the starry sky is not as shocking as seeing it with your own eyes. The human eye may be the best camera.

There were two thick black shadows on the ground, thin and long, extending to the edge of the roof. When walking to the center of the roof, only half of the shadows could be seen, and the other half seemed to fall straight down.

A large blanket was spread in the middle of the roof, and a dark rattan rocking chair was placed next to the blanket, which was covered with mottled scratches, as if it had been aged for some time.

Li Zhi sat cross-legged on the blanket, pointed to the rattan chair, "Just put the beer on it."

Lin Chaosheng also sat down, touched the blanket casually, it was very soft and slippery, and immediately said: "This feels so comfortable."

"Golden snub-nosed monkey hair, can you be uncomfortable?" Li Zhi said lightly.

"Huh???" The golden monkey... this should be illegal, right?

"You're kidding, Rabbit Hair." Seeing Lin Chaosheng froze for a moment, Li Zhi said slowly, "But there are really golden monkeys here, you might see them when you go down the mountain."

The golden monkey is a national first-class protected animal. When Li Wenjin first arrived here more than ten years ago, he encountered many poachers, so he would carry a hatchet with him when he went up the mountain to patrol.

Li Zhi had never been to Linchuan Mountain before he was in college, and he rarely met his father, but he prefers it to the compound where he has lived for more than ten years. He likes the quiet life in the mountains, and the rare animals and plants that can be seen everywhere. , and the sky full of stars that you can see when you look up at night.

Li Zhi was recalled, he lay on the fluffy blanket silently with his arms pillowed on his head.When most of his male classmates are stargazing outdoors, as long as there is a non-professional among the people present, they must not escape the fate of being "popularized". Li Zhi has no habit of popularizing science when he meets everyone, purely because of laziness.

He thought that Lin Chaosheng would be impatient to speak first, but unexpectedly, Lin Chaosheng was also quiet all the time, lying motionless on the fluffy blanket. Hearing the gentle breathing, Li Zhi once thought that the person next to him had fallen asleep.The breeze blew by, sending a burst of fragrance of grass and trees, the sound of insects buzzing in the ear, faintly mixed with a few dogs barking in the distance, and the sky full of stars twinkling, like a distant dream woven by the gods in the sky.

"The last time I saw so many stars was when I was in elementary school." Lin Chaosheng said suddenly.He lived in the outskirts of the city when he was a child. Later, when his family conditions improved, the family moved to the city. The city was full of tall buildings, and the night was as bright as day. Occasionally, he could see a few lone stars hanging high, but he never saw a star like him when he was a child. Such a starry night sky.

"It's really rare to see it in the city, but here you can see it every day as long as it doesn't rain." Li Zhi paused, and then said a little confused: "But it's quite strange to say, it's okay in normal times, as long as there is What astronomical phenomenon, it's either cloudy or raining here."

"That's really strange... Eh? I seem to see Orion." Orion is one of the most recognizable constellations. Lin Chaosheng stared at it with binoculars for a while, then pointed to the western sky, "Then What is that white thing, am I dazzled?"

"Pleiades star cluster." Li Zhi turned on the phone, and the faint fluorescent light reflected on his face, which looked faintly bright white. He glanced at the time and calculated the position of the stars.

"I can only recognize two or three. Can you recognize all the constellations in the sky?" Lin Chaosheng turned his face and asked him with interest, "I am a Leo, can you see it with the naked eye?"

When Li Zhi heard this, he suddenly smiled, it was a very obvious smile, his eyes narrowed, and the corners of his mouth raised, looking very happy, "Do you know who asked the constellation like that last time?"

"Who?"

"My cousin." Li Zhi said.

In Li Zhi's impression, those who are interested in constellations are generally young girls.He doesn't know astrology very well, after all, astronomy doesn't specialize in studying astrology.Every time Dai Yueran came here, he would pester him to ask him about the difference between wind signs and earth signs, whether personality is really related to astrology, whether Cancer and Sagittarius are compatible, and other low-intelligence questions.Li Zhi was annoyed by her questioning, so he directly dumped her a few books for her to read by herself, fooling her and saying, you will understand after reading it.

They are all extremely boring professional books, and there is no content about whether constellations and personalities are related at all, but Dai Yueran actually took it seriously, and spent half a month after returning home to finish the whole thick book, called him, and shouted Be deceived.

"..." Lin Chaosheng was silent for a few seconds, "So?"

Li Zhi still looked at him with a smile, "I can't read all the constellations, but there is a software that can do it, you can download it and have a look."

"Okay...so, can you tell me why you're smiling so hard?"

Li Zhi showed an obvious smile again, his eyes were very bright, and the pupils seemed to reflect the stars in the night sky, "I think you are a bit like my cousin."
