The Cowherd and Vega appear at what time of Tanabata

As the blueprint for the legend of Qixi Festival, the Morning Glory and the Weaver Girl and the seventh day of the seventh month are first involved in the ancient astronomical calendar and the astrological religion. According to the law of the development of the ancient mythological system, first from the "star to the god", and then from the "god to the man", the morning glory is also known as the "river drum", one of the twenty-eight nights, the second of the seven nights of Xuanwu, there are six stars (just the six stars of Capricorn in Greek mythology); On the other side of the Milky Way, Vega (the three main stars of Lyra). Altair is regarded as the god of grain by the ancestors of our farming Chinese nation, and the Weaver Girl is said to be the god of mulberry of the daughter of the Emperor of Heaven, and the god of grain and silkworm are the gods that the ancestors of our farming nation value very much.

The "seven" of Qixi is the habit of the summer calendar, and the ancient people often chose to sacrifice on the first and second seventh, and the number of sacrifices and rituals is often a multiple of seven.

On the seventh day of the seventh month, when no one whispered in the middle of the night.

Tanabata Cowherd and Vega cannot meet.

When you are enjoying the shade outdoors on a summer night, you can see a bright star above your head, and there are four small stars next to it, like a shuttle weaving cloth, which is Vega. Across the Milky Way, there is a bright star in the southeast, and a small star on each side, that is, the Cowherd Star, across the river from Vega.

Myths are myths after all, and it is impossible for the Cowherd and the Weaver Girl to meet overnight. Cowherd and Vega are both very distant stars, both of which are larger than the Sun, simply because they are very far away from us.

In astronomy, the distance between stars is mostly measured in "light years". A light-year is the distance traveled by sunlight traveling 300,000 kilometers per second in one year. The Cowherd is 16 light-years away from us, and the Vega is 27 light-years away, so it looks like a small point of light.

The distance between the Cowherd Star and the Vega Star is also very far, there are light years, and the distance between the Cowherd Star and the Earth is about the same, even if the Cowherd runs fast, he can run 100 kilometers a day, and it will take 4.3 billion years to meet the Weaver Girl. Even if it were to be changed to a spaceship that flew 11 kilometers per second, it would take 450,000 years to fly to the Weaver Girl. Don't say that they meet overnight, even if they make a **, it will take years to reach each other.

Inheritance significance. The legend of "The Cowherd and the Weaver Girl" originated and formed in Lushan, and the local Cowherd and Weaver Girl culture retains its original appearance. The earliest Ming Jiajing chronicles and the gazetteers of cities, counties and townships are recorded. Lufeng Mountain of Lushan is a unique peak, it is said to be the place where the Cowherd grazes, the first of the eight ancient views of Lushan, the Cowherd Cave under the mountain is the place where the Cowherd and the Weaver Girl meet, the descendants of the Cowherd often kneel in front of the Cowherd Cave and worship their ancestors.

The beggar of the Nine Women's Temple, the begging customs of the Qixi Festival, the eavesdropping custom under the grape trellis, the ancient temple fair of Qixi Festival in Xinji Township, Lushan County, the silkworm weaving in the mountainous area, the farmers' respect for the cow, the stark contrast between the ban on the performance of "Tianhe" in Sunyi Village, the hometown of the Cowherd, and the singing of the Cowherd and the Weaver Girl opera in other villages, etc., all show the deep cultural roots of the story of the Cowherd and the Weaver Girl in Lushan, and the people of Lushan have firmly believed that this is a real and beautiful story for thousands of years.

On the slope of Lu Mountain, even the Milky Way in the sky, the cow girl comes to meet, the world is happy, and the folk songs and ballads about the Cowherd and the Weaver Girl have been sung for thousands of years, but also retains the original folk culture, adding respect and remembrance to this love story.

Yes! After all, ideas are always good! It's just thinking'Not reality!

Legends do, but that's legends after all.

It depends on the location, and it is also related to the weather, not necessarily.

Extended information: Brother Sheng sells the Cowherd and the Weaver Girl, a famous Han folk love story in ancient China, and one of the four major folk legends in China (the other three are "Liang Shanbo and Zhu Yingtai", "Meng Jiangnu Crying on the Great Wall" and "The Legend of the White Snake"), derived from the star names of Altair and Vega. Legend has it that the ancient Emperor of Heaven's granddaughter, Weaver Girl, was good at weaving cloth and weaving colorful glow to the sky every day.

She hated this boring life, so she secretly went down to the mortal world, married the cowherd of Hexi privately, and lived a life of male farmers and female weavers. This angered the Emperor of Heaven, who took the Weaver Girl back to the Heavenly Palace, ordered them to separate, and allowed them to meet only once a year on the seventh day of the seventh lunar month on the Queqiao Bridge.

Cowherd Star: River Drum 2, the famous "Oxherd Star", "Aquila" (Altair), also known as "Altair" or "Great General", is called "Hikoxing" in Japanese. The twelfth bright star of the day, white.

In starry sky observation, it is a corner of the summer triangle. Its line with the constellation Aquila is pointing towards Vega. The West calls this star altair, which is the Arabic word for "flying eagle" (alnasr-l'tair:

Abbreviation. Location: 19 o'clock right ascension, 8 degrees 44 minutes declination.

Vega: Also known as Vega or Lyrae, Vega is the brightest star in the constellation Lyra, fifth in the night sky, and the second brightest star in the Northern Hemisphere, after Arcturus.

Like Arcturus and Sirius, it is a star very close to Earth, only light-years away; The temperature is slightly cooler than Sirius. It is also one of the brightest stars near the Sun. In the ancient Chinese myth of the Cow's Head and the Weaver Girl, the Weaver Girl was the granddaughter of the Emperor of Heaven, so she was also called the Heavenly Sun.

Astronomers have studied Vega extensively, so it is "undoubtedly the second most important star in the sky, after the Sun". Vega was the starvation pole in the Northern Hemisphere around 12,000 BC, but due to precession, it will become North Star again in 13,727, when its declination will reach +86°14'。Vega was the first star outside the Sun to be photographed by humans, and the first star to have a spectral record.
