Tibetan border guards filmed the starry sky. Why is the most beautiful starry sky always in Tibet?

With the coming of the National Day and Mid-Autumn Festival, every family gathers together to celebrate these two festivals, but the soldiers in the frontier still silently stick to their posts and defend their country! Bian Xiao saw the beautiful starry sky video shot by soldiers in Tibet's border areas released by People's Daily Weibo. The starry sky in the video is like a dream, which is a beautiful scenery that can't be seen in the city, and Bian Xiao thinks it is the most beautiful scenery with the most beautiful people! But why is the most beautiful starry sky always in Tibet?

This actually has a lot to do with the geographical location of Tibet. Tibet is located in the southwest of the Qinghai-Tibet Plateau, which is the highest plateau in the world, so the average altitude of Tibet is above 4000 meters, so it is called? Roof of the world? . The higher the altitude, the closer it is to the sky, and it will be clearer than other places with low altitude; In addition, due to the high altitude, the sky atmosphere in Tibet is relatively thin, there are fewer clouds, and the blocking rate of the sky is small, so it will not block the stars in a large area, so it is easy to see a large area of starry sky at night in Tibet.

Secondly, because of Tibet's high altitude, clean air, less particulate matter in the atmosphere, less astigmatism to starlight and moonlight, and Tibet's independence time is late, the degree of development is small, the air pollution is small, and it is far away from light pollution, so the starry sky in Tibet will become clearer and clearer. In addition, winter in Tibet is affected by the alternating west wind and southwest monsoon, and the dry season is distinct. The general dry season is from June 10 to April of the following year. It was mostly sunny in Tibet during this period, and there were few dark clouds in the sky, so the night in Tibet always presented beautiful starry sky, and this period was also the best time for Tibet to watch the starry sky!

Now friends should know why the most beautiful starry sky is always in Tibet! In fact, it is not only because of nature's ingenuity, but also because of our most beautiful soldiers, who can abandon their small families and come to the frontier of Tibet to defend the territory of the motherland and defend this most beautiful starry sky!
