bright and colorful

? Astronomy enthusiast magazine commented next to a beautiful photo of a thunderstorm night sky. When it comes to the night sky, do you think of the word "darkness"? In fact, the night sky is colorful, and various phenomena such as reflection, refraction and scattering make the night sky show various colors.

I never thought I could just look up at the night sky and it would pass in four or five hours. I was surprised when I first saw the moon rise. It was sultry when I wandered around the clouds after the moon rose. Clouds are thick or light, and the moon can even be deep red, with all kinds of light and shadow changes. The stars in the sky are flashing, rising, moving and sinking. The milky way is like a hazy white practice, crossing the starry area. Occasionally, meteors pass by, beige or fiery red, leaving a fleeting white mark. On a thunderstorm day, thunderous lightning appeared in the clouds, turning the night sky into sauce purple and lake blue. I only heard thunder rumbling and dark clouds rolling up to the sky.

? The splendor of the night sky is not that gorgeous beauty, but quiet, quiet and restrained. I'm afraid I can't understand if I'm impetuous, and it's hard to understand if I'm boring. In the rain, Leo 200 1, I intend to dedicate the night to the library and the thick Longman Ying Ying dictionary. Two girlfriends dragged me to Tsinghua to see meteors, and I shamelessly hesitated. As a result, I was stunned by the dazzling meteor flash that night. Perhaps it was the first time that I felt that there was something else in the night sky besides black, and I realized how vast the world was and how infinite life was. Compared with it, learning this thing is really too small. Two girlfriends can't remember the night of the meteor shower when we were frozen in Tsinghua playground, but this night has inspired me with the philosophy of life.

In fact, I didn't always look up at the night sky after that, until my son was fascinated by astronomy and dragged us to see this star and that star. He and dad can watch for a long time and want to know which is which, but I have no motivation to go deep, just appreciate the beauty on the surface. Miao village, Dong village, east, west, north and south all left our star-watching footprints. This summer, we should have watched the Perseid meteor shower in Chaka Salt Lake. Because we were not allowed to leave Beijing, we came to Yanqing Astronomical Farm: Huahai Pastoral.

It is said that this used to be a farm yard. Later, the boss found out why so many people came to see the stars, and this place was transformed into a farm dedicated to watching the stars. He spent a lot of money to buy various high-end astronomical equipment such as telescopes, which can be rented to visitors. According to the boss's son, there may be only one such farm in China, because of the small population and the high equipment investment. When we were watching the stars, we met a veteran player with hundreds of thousands of astrophotography equipment, which also confirmed that at least around Beijing, this is the only place where we can watch the stars professionally and freely. Other places, such as Lingshan, Jinshanling Great Wall, Miyun Bulaotun, etc., must bring their own tents for camping.

The night when advanced players came, it was the lunar calendar 14. That night, there was the roundest moon in the lunar calendar 14 years, which only appeared six times every 100 years. When I was chatting with my best friend that day, I accidentally caught a glimpse of a bright yellow light coming out of the distant hill. The more exposed the light, the whole circle is seen from arc to semicircle and then to big semicircle, and the sunset glow is like sunrise. "the moon!" Turn off your phone quickly and look greedily (poor city dwellers! )。 The moon can be used as a street lamp at night. Bright moon and stars, isn't it great? However, the vast farm is empty except for the three veteran players who are connected to the computer with binoculars and SLR. It turns out that the roundest moon is the biggest obstacle to stargazing that night: super light pollution! Players will still come, because a new wisdom comet that only visited the earth once in 6000 years will come to a galaxy tonight, and the camera can capture it. Although there is a moon in the way, when there is no moon, the comet may leave, or the comet and the galaxy cannot be photographed together. Give up, give up, life is a process of weighing and letting go.

At night, dogs, donkeys and sheep bark around the farm, which is even more silent. A week later, on the night of the meteor shower, the stargazing platform was crowded with figures and telescopes, and only one or two dogs barked occasionally. After work, advanced players drive here directly from units unrelated to astronomy to shoot comets and M64 galaxies. First, control the telescope and SLR to locate automatically on the computer, shoot for 2 hours, and then do the synthesis work later.

The green star with a tail is a comet, but the green color can't be observed by naked eyes. The hazy star in the upper left corner is M64.

The person I especially admire is such a person who has something he really likes, is very devoted and leads a gorgeous and energetic life.

The next night, I began to wait for the moon to rise early.

The sunset disappeared, but the moon didn't appear on the mountain yesterday. On inspection, the moon is still below the horizon. This is a beautiful night. At eight or nine o'clock, the moon shone in the clouds for the first time. Then it appeared in the light cloud, which was much softer than last night.

?

The third night was cloudy, with no stars and no moon. My father and son went out to try their luck at nine o'clock. Just after they went out, my phone rang. "Come out, come out!" Go out in a hurry, "look at the sky, hurry". Can't wait to get on the platform? As soon as I looked up, a crimson moon was hidden behind the gauze-like clouds, charming! Hurriedly on the second floor platform, look again, the moonlight is brighter than before, and it can't return to the artistic conception just now. The moon just appeared when the father and son said to call me.

The night sky changes endlessly, and the next second is different from what I saw this second. Often, it's almost midnight.

The night of the biggest Perseid meteor shower, unfortunately caught up with the rainstorm. The night after that, fans came, children studying abroad came, and girlfriends came. There are many telescopes on the platform, and even more complex equipment. Later, I learned that there were senior players in it that day, and I couldn't see Xinzhixing gradually moving away from the earth when I took that tail. Every time a meteor passes by, the crowd is in a commotion, "Wow!" "Meteor!" "hey!" "This way!" People who see it are excited, and those who miss it are sorry. This is nothing compared with the Leo epidemic 20 years ago. At that time, it was a golden light followed by a golden light, and even dozens of golden lights crossed at the same time. At this time, you need to concentrate on looking at the sky. It would be nice to see one in ten minutes. According to Murphy's law, meteors usually pass by when you look down at your mobile phone.

On the day of Yanqing, it happened that the Badaling Great Wall had a night tour, and we also went to join in the fun and felt another kind of excitement.

Lighting landscaping is also an art. After heavy rain washes crowded people home, the night view of the Great Wall is comfortable, inconspicuous and undisturbed. What I don't like most is that some caves illuminate all kinds of stalactites with colorful and vulgar light, so it is better to expose the face of the stone as much as possible, just like Zhijin Cave in Guizhou. I don't really appreciate the colorful Zhenyuan night in Guizhou.

If I hadn't been trapped in Beijing because of the epidemic, I might never have thought of staying at the foot of the Great Wall. An ancient city of more than 460 years is hidden at the foot of the Great Wall. It was built in the 30th year of Jiajing in Ming Dynasty (155 1), with more than 1000 households and a prosperous market. It used to be the outpost of Badaling Pass and the main road to Beijing, with nearly 1,000 permanent defenders. Now it is a street in B&B, where a group of unusual people are chasing their dreams. The Great Wall Hotel where we stayed. The boss used to do Hetian jade business. Because he likes the Great Wall, he came here with his jade family and opened a jade shop. Now he is a homestay. But dreams still have to compromise with reality, because children's primary education can't let the whole family enjoy a quiet life here. The proprietress and her son have to go to school and work in Beijing from Monday to Friday.

? There was also an encounter in Badaling Wildlife Park. Because we didn't drive, we had to walk down the mountain and go with a keeper. He fed for the last time before going to work. I saw him feeding the fox, and the fox was scared to hide. People dare to come out for dinner when they are gone. Go to the henhouse and drive the chicken into the cage and take out an egg. The animals here are so used to being fed that even the horses beg in front of the car for stuttering. Foxes that hide in fear often get chicken legs. A player who likes animals and zoos, taking playing as his major, visited and observed many zoos around the world and wrote a book called Going to the Zoo is a Serious Business, which turned his love into a career, popularized the concept of animal welfare, the correct concept of zoo play and a higher level of animal pleasure, and benefited human beings and animals. He is a flower erosion teacher who is particularly opposed to animal feeding and hates begging.

We never thought about going to the World Garden Expo in Yanqing 20 19, and we don't want to go on this trip. As a result, because there was nowhere to go, we went reluctantly. We were surprised by the colorful buildings around the world in the park. The so-called ignorant people are all too shallow and self-righteous. The buildings and gardens built with care reflect the culture and unique thinking of that country or region. Looking at some of these buildings, we can recall the people we have met and the experiences related to this country.

Yanqing has many green areas and low population density. Driving in the suburbs is a bit like dressing up in America. There is no convenient bicycle sharing here, only people over the age of 18 can share bicycles, so a bicycle rental company was born. Stepping on the Earth, I like the name very much. Rent a car for one day 108 yuan, if you ride in the Baili Gallery 138 yuan. My son Xiao Bai is riding a bike. He learned to drive when he was 9 years old. After learning that, he put the car on the shelf and didn't touch it for two years. Almost 12 years old, just take this opportunity to do street training. For the first time, I rented an ordinary car to ride in Yeyahu Park for 5 hours, and for the second time I rented a professional-looking car to ride in Guishuihe Forest Park and the urban area for 6.5 hours.

Riding on Wild Duck Lake is a bit thrilling. We turned into a deserted path and went deeper and deeper. We almost reached the intersection of the main road. Suddenly, we saw two big black dogs walking back and forth on a road ahead. Dad shouted, "Evacuate!" The three men quickly returned from the original road, and when they returned, it seemed to be a construction site in the park. Black dogs are probably gatekeepers, so they can't be gentle. The price of adventure, I said, "the result is good, the adventure is good." Back on the main road, we breathed a sigh of relief. There are flat roads, muddy roads and a dangerous one in Yeyahu. The dirt road is particularly narrow, with reeds on both sides. I don't know how deep the water is under the reed. If the car slips into the water, the consequences are unimaginable. There are so many mosquitoes. It is no exaggeration to say that our legs were covered with mosquitoes when we passed that area.

? Guishuihe Forest Park has a special bicycle lane, which goes up and down, across rivers, across rice fields, and meets hemp nests and camel nests. Not enough riding, we rode on the highway and arrived at the location of Yanqing Bicycle Association. Yanqing Gymnasium turned around and passed through the major parks in the city. It is really the city of parks.

I still feel that I have to weigh my steps before I can feel this trip. The next best experience is cycling.

Still three backpacks, we came to Yanqing. I lost my desire to watch the meteor shower in Chaka Salt Lake for a while, but as long as my heart is colorful, everything can be colorful, right?
