What's the use of Ursa minor and Ursa major?

Connecting the seven bright stars in Ursa major can form a bucket similar to the Big Dipper in Ursa major, so these seven stars are also called Ursa minor. Bucket handle begins with Alpha Ursa minor, which is now the North Star, indicating the North Celestial Pole.

Polaris can be found by drawing a straight line from the two stars β (Tian Xuan) and α (Shu Tian) in the constellation Ursa Major and extending it to five times the distance between the two stars.

At different latitudes of the earth, the constellations you can see are different. The constellation Ursa major can be seen all year round in areas above 40 north latitude, that is, north of Beijing and Greece. However, in spring, Ursa major is high in the northern sky, which is the best time to watch its panorama in four seasons.

The star of Ursa major.

Ursa major ranks third in the whole sky, second only to Ophiuchus and Virgo. Because of the existence of the Big Dipper (from Alpha Ursa major to η Ursa major, except for Delta Ursa major, the other six are bright stars above second star), Ursa major is probably the most famous constellation in the whole day. The first two stars of the Big Dipper, α and β, are signs for finding the North Star, and the connection between these two stars directly points to the North Pole.

The second star with spoon handle (ζ Ursa major) is actually a cluster star, and we can see a fourth-class companion star Alcor with naked eyes. Through the small telescope, we can also see another star near Ursa major, which is also a 4-star. In fact, these three stars are each a binary system, so this is a six-star system. Another interesting thing is Ursa major ξ, which is a binary star system, consisting of two * * stars, moving with each other for 60 years. This constellation has two spiral galaxies: M8 1 of 8 and M 10 1 of 9.

Ursa minor, the nearest constellation in the north celestial pole, Ptolemy and the modern 88 constellations all include Ursa minor. Ursa minor marks the position of the north celestial pole, and Alpha Ursa minor, the brightest star in the constellation, is the current Polaris.

Legend 1

Ursa minor represents one of the goddesses who raised Zeus.

Legend 2

Ursa minor represents Akka, the son of Zeus. Once, Zeus fell in love with a Zhu Fu named Caristo, and soon Caristo became pregnant and gave birth to Zeus' son Aka. After learning this, the angry diva Hera changed karis into a big bear, and she had to live in the forest. Many years later, Caristo's son Aka grew up and became an excellent hunter. On this day, Aka was hunting in the forest. Caristo recognized her son, but forgot that she was a bear. She ran to him involuntarily. However, Aka didn't know that this terrible bear was his mother, so he raised his pike and pointed it at the bear. At this dangerous moment, Zeus quickly turned Aka into a bear. Achatz, who became a bear, recognized his mother, thus avoiding a tragedy of killing relatives. Later, Zeus took two bears to heaven and gave them two glorious positions among the stars, Ursa Major and Ursa Minor.

Hera also sent a hunter with two fierce hounds to chase the two bears. This hunter is the shepherd in the sky, and the two hounds he leads are the dog constellation.

The ancient Greeks saw this big bear wandering in the sky every night and never fell below the horizon. They think this must be Hera's trick again. It turned out that Hera sent hunters and hounds to hunt down the mother and son, but she still refused to give up. She came to the blue sea again and asked her brother Poseidon for help. Poseidon listened to his sister's story and agreed to her request. So we can see that other constellations have the phenomenon of rising east and setting west. There is always a time when they sink below the horizon and go to Poseidon's territory to rest. Only the bear and the girl are discharged from the hospital.

The bright star in Ursa minor is excluded. But fortunately, Crystal can stay with her Achatz all the time, so that Hera won't come up with any bad ideas.

UMa is one of the northern constellations, located near Ursa minor and Leo, opposite Cassiopeia. Suitable for spring observation, it is the constellation of the famous Big Dipper.

greek mythology

Mother-child relationship

In ancient Greek myths and legends, there was a beautiful and kind girl named Crystal. Among the fairies around the moon god and the hunting goddess Artemis, she is the most touching one. But she never relied on it. She is always very kind to every partner, and let everyone feel her heartfelt care from time to time. People also like her very much, and everyone has a carefree and happy time together. What makes Callisto, the star of Ursa major, different is that her gentle appearance contains a resolute character. Unlike other fairies, she wandered around the stream all day, strolled in the garden, recited poems and danced. She always wears a mighty hunting suit, carries a bow on her shoulder, and holds A Jin hair, bravely following Al themis to chase wild animals in the mountains and forests. The tiger's roar made all the animals tremble, but it didn't scare her, and the cunning fox couldn't escape her vigorous skill. She became Al themis's most effective and trusted assistant.

On a hot summer day, callisto drove wild animals to a clearing. Hot and tired, she lay in the shade and soon fell into a deep sleep. All this was seen by Zeus Almighty. In ancient Greek mythology, Zeus was the biggest god in the sky and the father of the gods. He is supreme and admired by all things, but he often does shady things. It is common for him to secretly seduce the goddess in the sky and the beauty on the earth.

Zeus was surprised to see the beautiful Callisto lying on the green grass, and he naturally refused to miss such an opportunity. He flew down from the clouds and became the image of Al themis. He approached Crystal gently and held her in his arms. Crystal woke up from her dream and was inexpressibly happy to see Artemis in this remote place. Was about to stand up and continue hunting with themis when Zeus suddenly showed his true colors. Poor callisto was unprepared. She fought hard, but to no avail. After all, Zeus is omnipotent. Although Callisto has the ability to subdue dragons and tigers, it still can't escape Zeus' clutches. Zeus proudly returned to the Heavenly Palace. As the master of the universe, he will naturally not be punished or rewarded. Unfortunately, it can only be innocent Callisto! She wiped away her tears and silently returned to everyone. I can't tell you how painful I am, but I have to smile in front of everyone. However, old Callisto will never see it again. She always lowers her head and looks at the ground in shame; The smile on his face disappeared, and he often sat silently away from everyone; When hunting, I don't have the courage and aura to watch the prey slip away from my eyes. To make matters worse, Ursa Major found herself pregnant. No matter how to hide it, finally one day, everyone still knows the secret. Artemis, who knew nothing about it, was furious. Although she regarded Crystal as her daughter, she couldn't restrain her anger and drove her out of the hunting ground.

Helpless callisto built a thatched shed deep in the forest and settled down. He can no longer see the laughter of his sisters and hear the call of the goddess. Soon after, she gave birth to a boy and named him Arcaz, which became a little sustenance in her life.

Zeus thought it was secret and no one would know. However, when God also miscalculated, his wife Hera, the queen of God, heard about it. Hera was born in a noble family and was arrogant since childhood. Even Zeus sometimes had to respect her. Zeus did such an ugly thing behind her back. Little Achatz was born and was walking with his mother! Hera, who has always been uncompromising, is going crazy. She vowed to punish Crystal with her magic and let her know the majesty of Tianhou.

Hera came to the woodland where Crystal lived and swore at her as soon as she saw her. Regardless of Crystal's pleading, she threw her to the ground by pulling her hair and said cruelly, "I'm going to ruin your beauty so that you can't be charming anymore!" "

While speaking, Hera secretly cast a spell. Suddenly, Callisto's snow-white arm grew long and thick black hair, delicate fingers turned into sharp claws, and delicate red lips suddenly turned into maw. Hera is still not Japanese. She was afraid that Crystal's prayer would be heard by Zeus, so she was deprived of the ability to speak and turned the silvery voice into a dull roar. In a blink of an eye, the angelic Callisto disappeared forever and she became a big bear. Location map of Ursa Major Poor Crystal wanted to cry, but she kept wailing, lamenting her tragic fate and cursing the heartless Zeus. Once upon a time, that brave hunter has become a beast chased by hunters, hiding in the deep mountains and forests all day, and there is no peaceful time in the past.

Time flies, fifteen years have passed. Little Achatz grew up to be a beautiful young man, as brave and determined as his mother, and became an excellent hunter. One day, Hera happened to meet Achatz. The son of her enemy is so handsome. More than ten years ago, the evil spirit came to my mind, and a deadly trap was born in her heart.

One day, Achatz was looking for prey in the forest with a pike in his hand. Suddenly, a big bear came slowly towards him. This bear is Callisto. She recognized that the brave hunter in front of her was the little Achatz she had been missing for fifteen years. She excitedly ran to hug her baby.

God, how could Achatz think that this bear in front of him is his mother who has been lost for fifteen years! Seeing such a big bear coming at him, he flashed back excitedly, raised his spear and stabbed the bear with all his strength.

Seeing a tragedy is about to happen. Fortunately, Zeus, who was touring the sky at this time, saw this scene. He really couldn't bear to let his son kill his mother himself. So he turned Achatz into a bear with a little magic. In this way, little Achatz immediately recognized his mother. He came running affectionately and snuggled up in his mother's arms, and the mother and son were happily reunited.

In order not to let the mother and son suffer any more accidents, Zeus lifted them to the sky and gave them two brilliant positions among the stars, namely Ursa Major and Ursa Minor, which shone brilliantly in the northern sky.

Hera stole the chicken and wasted the rice. She was furious, but she couldn't anger Zeus, so she sent a hunter with two fierce hounds to chase the two bears. This hunter is the shepherd in the sky, and the two hounds he leads are the dog constellation.

The ancient Greeks saw this big bear wandering in the sky every night and never fell below the horizon. They think this must be Hera's trick again. It turned out that Hera sent hunters and hounds to hunt down the mother and son, but she still refused to give up. She came to the blue sea again and asked her brother Poseidon for help. Poseidon listened to his sister's story and agreed to her request. So we can see that other constellations have the phenomenon of rising east and setting west. Once in a while, they sank below the horizon and went to Poseidon's territory to rest. Except for two bears. But fortunately, Crystal can stay with her Achatz all the time, so that Hera won't come up with any bad ideas.

Oriental legend

Beidou Shen Jun

China called the Big Dipper the King of the Big Dipper in ancient times. As the saying goes, "Nandou is reborn, Beidou is dead." It is said that the king of the Big Dipper holds the power of life and death. It is said that Peng Zu begged for his life from the Big Dipper, so he lived 800 years. It is said that there are nine planets in the Big Dipper, two of which are hidden in the bucket, and the Jade Emperor Shen Yuan is in the bucket, so it is not easy to be seen. If someone sees it, they can prolong their lives. It is said that Huo Guang, the prime minister of the Han Dynasty, had a servant at home. One day, when he saw two bright stars in the bucket of the Big Dipper, he bowed down devoutly, and his life expectancy increased by 600 years. According to this legend, Ursa major and Ursa minor are really worth seeing.
