The planetarium had just opened, and there were no people inside.

Jimeng and Gangya both wore hats and masks, but even that caught the attention of the staff.

"You two, do you need a narrator?" The staff stepped forward and asked with a smile.

Ji Meng looked at the steel teeth, thought for a while and said, "That...... Okay, but how much does the narrator cost? ”

"Oh, narrator, one hundred. But you're all together, so it's a hundred. ”

"Okay, that's you, right?" Ji Meng asked with a smile.

The staff smiled and nodded a little embarrassedly.

Ji Meng looked at the staff member, who looked no more than twenty years old, and looked a little like a college student.

"You can't be a work-study student, are you?" Ji Meng asked with a smile.

"Hey, you're really eye-catching, I'm a work-study student." The staff replied with a smile and nodded.

Then, the narrator took Jimeng and Gangya to set up a planetarium restaurant.

In fact, there is really no great need for a commentator, and there are all kinds of video materials and interactive query equipment in the exhibition hall.

But with him to explain, you don't have to be headless and brainless.

But after reading it all over again, Ji Meng still didn't find a clue.

"Well, excuse me, what is excluded?"

"Huh? What do you mean by that? I don't understand? "Let's have a book

Ji Meng's clueless question made the commentator confused, Ji Meng thought about it, and felt that his question was indeed a little weird, and then said:

"Well, I have a friend who gave me a puzzle and he said, 'Heaven has all the answers, look up, and the one who is excluded is the answer.'" , but I don't understand what is excluded. ”

The narrator tilted his head and thought about it, then his eyes suddenly lit up and said, "Is this...... If it is said that the excluded ...... I do know one.

You should know about the zodiac, right? To put it simply, you girls should like zodiac signs, right? ”

"Uh...... What are you talking about Aries, Taurus, Scorpio, Aquarius, or whatever? ”

"Yes, that's right, that's it. But in fact, it was supposed to be thirteen constellations, but because Westerners think that thirteen is an unlucky number, the original thirteen constellations became twelve constellations, and the constellation that was excluded was Ophiuchus. ”

"Ophiuchus? I think I've heard of it too. Ji Meng tilted his head and said as he thought.

"Ophiuchus has a great reputation for being the only one that is located on the ecliptic but is not part of the zodiacal sign.

Ophiuchus is also the only sign of the zodiac that is connected to another sign, Serpentus.

At the same time, Ophiuchus is also the only constellation that crosses both the celestial equator, the galactic and the ecliptic.

Legend has it that this constellation is Asclepius, the god of medicine, and because he often used poisonous snakes to heal diseases, he was in the image of a man holding a giant serpent with both hands.

He was the son of Apollo and Colonis, and Asclepius tried to resurrect Colonis when she was killed by the Golden Bird.

But Hades, the king of the underworld, knew about it and thought that he had violated the rules of heaven, so he killed him with a thunderbolt. After that, Zeus added him to the constellation.

From the star chart, the constellation Ophiuchus looks like a big bell with a buckle in it, and the brightest α star in the constellation is the top of the clock.

He forms an isosceles triangle with Cowherd (Aquila) and Vega (Lyra), and this method can quickly find Ophiuchus.

The Ophiuchus constellation is somewhere between Scorpio and Hercules, and the Royal Astronomical Society says that people born between November 29 and December 18 should be Ophiuchus rather than Sagittarius. ”
