What is Tianhe?

Milky Way

Note: In astronomy, the Milky Way is not equal to the Milky Way. Reference entry "Galaxy"

The bright band of the main part of the Milky Way projected on the celestial sphere is called the Milky Way in China.

In the clear night sky, when you look up at the sky, you can not only see countless shining stars, but also a faint scarf-like light belt across the whole sky, just like a big river in the sky, which runs north-south in summer and close to east-west in winter, that is the Milky Way. In the past, because science was underdeveloped, we didn't know what it was, so we named it Tianhe. Therefore, there are many fairy tales in our country. For example, Cowherd and Weaver Girl meet at Queqiao on Tanabata every year.

In fact, the Milky Way is a part of the Milky Way, which belongs to the Earth and the sun. It is named because the bright band whose main part is projected on the celestial sphere is called the Milky Way in China. It is the round face full of stars that we see when we look at the Milky Way from the inside. Because the light emitted by the star is far away from us, it is large in quantity and mixed with interstellar dust gas, so it looks like a band of light shrouded in smoke, which is very beautiful.

The brightness of each part of a galaxy is different. The direction of Centauri near the silver heart is brighter than other parts.

Research on galactic history

Since ancient times, people have attached great importance to the observation and research of the Milky Way.

The ancients didn't know what the Milky Way was, so they imagined it as a river in the sky. China's famous fairy tale, Cowherd and Weaver Girl, met at the Magpie Bridge, which is located on this Tianhe River. Altair and Vega on both sides of the Milky Way are particularly eye-catching in the night sky. Altair is the brightest star in the constellation Aquila located on the east bank of the Milky Way. Vega is the brightest star in Lyra on the west bank of the Milky Way. Westerners believe that the milky way is formed by the milk flowing out when the queen is nursing, which is called milk passage. That's how the Milky Way in English came from.

Beautiful fairy tales cannot replace satisfactory scientific explanations. What exactly is the Milky Way? After the invention of the telescope, this question got the correct answer. /kloc-At the beginning of the 7th century, the great Italian scientist Galileo aimed his telescope at the Milky Way, and was surprised to find that the Milky Way was originally formed by many stars gathered together. Because these stars are too far away from us, people's eyes can't clearly distinguish them and regard them as bright bands of light.

Yinhe queqiao xianghui

The seventh day of the seventh lunar month is the most romantic "Tanabata" among the traditional festivals in China. It is a legendary day when the Cowherd and the Weaver Girl meet once a year on the Bridge of the Galaxy, and it gradually evolved into Valentine's Day in China. Therefore, every Valentine's Day, lovers always look up at the stars and pray that love will be faithful.

According to experts from Jiangsu Astronomical Society, Cowherd and Weaver Girl are folk names. In fact, in astronomy, Cowherd's Chinese name is Hegu II, and Vega is Vega I, which are two bright stars in Aquila and Lyra respectively. Because these two stars are clearly visible to the naked eye and easy to distinguish, Vega was once one of the navigation marks of Zheng He's voyage to the West in the Ming Dynasty.

On a sunny night, you can find a safe place that is not affected by city lights, preferably about two hours after dark, when there is not much moonlight influence. Make an appointment with friends and relatives in advance and find a lounge chair. Look up on a quiet night. When you see the Milky Way across the sky, you will have a comfortable spiritual enjoyment. Near the top of the head, there are three bright stars in the middle and on both sides of the Milky Way. The brightest is blue and white. She is in the northwest of the galaxy. This is Vega. There are four dark stars below Vega, forming a small parallelogram. They are beautiful clouds and rainbow shuttles woven by Vega in myths and legends. Another bright star is in the southeast of Vega, which is the southeast edge of the Milky Way. He is Altair (also known as Hegu II). Cowherd is a bright yellow star, and the two small stars on both sides of him are called shoulder pole stars. According to legend, Cowherd is pregnant with a pair of children.

According to the results of modern astronomical observation and calculation, Altair is 16 light years away from us (1 light years is about 10 trillion kilometers), Vega is 26 light years away from us, and the distance between the two stars is 16 light years away. Even if Altair calls for Weaver Girl, Weaver Girl will not hear Altair's voice until 16 years later. So they can't meet on July 7th every year.

Legend has it that why should the seventh day of July be regarded as the day when the cowherd and the weaver girl meet? This is because the ancients thought that "seven" was an auspicious number, which meant perfection. Moreover, on the night of July 7, when the moon approaches the Milky Way, the moon's brilliance can just shine on the Milky Way, which is more convenient for people to watch the stars. If you observe it with an astronomical telescope tonight, you will see dense clusters in the Milky Way. The afterglow of the half moon sprinkled on the Milky Way has become an imaginary "magpie bridge".

According to reports, why should the legendary lunar calendar "the seventh day of July" be regarded as the meeting day for cowherd and weaver girl? This is because the ancients thought that "seven" was an auspicious number, which meant perfection. Moreover, on the night of July 7, when the moon approaches the Milky Way, if you observe it with an astronomical telescope, you will see dense clusters in the Milky Way. The afterglow of the half moon sprinkled on the Milky Way has become an imaginary "magpie bridge".

It's midsummer now. At about 9 pm, Vega with zero brightness first appeared near the zenith, and then there was a first-class Altair in the south. In the suburbs far away from the city lights, citizens will be pleasantly surprised to find that there is a white Tianhe (Milky Way) across the north and south between the two stars, in which Altair is in Hedong and Weaver Girl is in Hexi. They looked at each other silently, which was quite poetic.

Galaxy literature

Galaxy has many interesting nicknames in China's classical poems, such as:

"Star Han" and "Star Han is brilliant, if it is out of its territory" in Cao Cao's Watching the Sea.

"Tian Han" in Lu Ji's Imitation of the Moon and the Night, "Swinging in the northwest means southeast".

The "Jiang" in Du Qixi's "White dew contains the bright moon, and the blue sky breaks the river".

Han Yun in Li Bai's Drinking the Bright Moon Alone, is goodwill guaranteed? I watched the long road to the Milky Way.

The "Milky Way" in Du Fu's "Pavilion Night", "Stark sings the fifth watch, beats the drum and blows the horn, and the Milky Way runs through three mountains".

"Tianhe" in Wang Jian's Autumn Nightingale, "Tianhe leaks long, and Beidou in the south building is second-class".

"Pu Yin" in Li He's "A Ballad in the Sky", "The Tianhe River turns back to the stars at night, and Pu Yin learns the sound of water in the clouds".

"Silver Bay" in Li He's "The Stream is Cool in the Evening", "Jade smoke is as white as a building, and the Silver Bay turns east".

"Long River" in Li Shangyin's the Goddess Chang'e flying to the moon, "The shadow of the mica screen candle is deep, the long river is gradually falling, and the stars are sinking".

Synopsis: The film mainly tells the story of some Christians on their pilgrimage to a small town in Spain. After their arrival, they discussed the Christian doctrine and the story of Jesus. During the discussion, there were criticisms of the Pope and questions about the way God exists. Why does God exist in the world and what does God want to bring to people?

In this film, bunuel, as always, launched a fierce bombardment of religious bigotry. The film is led by two pilgrims who beg for vagrancy and sometimes steal things, starting from Paris, and then following the "San Diego Road" to the Campestria church in San Diego, Spain. On the way, they met all kinds of weirdos, except the Virgin Mary and Jesus Christ, and the erotic Sadr. Some people even suggested that Jesus shave off his beard. The five minutes at the end of the film were well received. Jesus came to a small river, pretended to treat the blind miraculously, spat in his eyes to restore his vision, and then jumped over it easily and naturally. We only saw his feet standing by the river for a while. Touch the ground with crutches and feel the depth and width of the river. Immediately, I saw their hesitant feet. Subtitles appear on the camera: from a doctrinal point of view, the Catholicism and heresy derived from Catholicism involved in this film are absolutely accurate. Scriptures and quotations are taken from the Bible, ancient and modern theological works and church stories. The bell rang even louder. The movie is over. Bunuel's unique creation brought people into a magical situation, and performed a wonderful theological fantasy in the screen world beyond time and space.
