Hogwarts Asylum

Astronomy class is held every Wednesday night. In this class, the little wizards basically use telescopes to observe the starry sky and learn the names of planets, stars and constellations, as well as their positions, orbits and environments.

When they first took the astronomy class, almost all Gryffindor students underestimated the height of the Astronomy Tower. Everyone thought that the Astronomy Tower, which looked not much taller than Gryffindor Tower, was easy to climb, so everyone was late. .

Fortunately, Professor Aurora Sinister, who teaches astronomy, is a very gentle lady. Her heart is as tolerant as the stars, and she very generously forgave Harry and others who were at least 10 minutes late.

Including Harry and Hermione, most young wizards of Muggle origin like this course because they were exposed to the same content when they were in Muggle primary school. Although they read it in books, it was better than Others learn faster.

But tonight, Harry was surprisingly in a daze, and didn't even hear Professor Sinistra call him to answer a question.

"Harry, Harry." Ron poked Harry next to him.

"Huh? What's wrong?" Harry came back to his senses and saw Ron pointing to the middle of the astronomy tower. Following the direction of Ron's finger, he saw Professor Sinistra looking at him, and Harry immediately shrank. Neck.

"Why didn't you call me earlier?" He complained softly and stood up quickly, "I'm sorry, Professor, I was fascinated by the stars just now."

Professor Sinistra squinted his eyes and smiled, and said gently: "It's okay, Harry, sit down. Like you when I was in school, I often looked at the stars and was fascinated, and sometimes I even forgot to go back to the dormitory.

However, I still suggest that you listen a little more carefully the next time you go to class.

Having said that, let me teach you one more thing. "

After Harry sat down, he immediately listened with all his concentration, fearing that he would be too embarrassed if he accidentally lost his focus again.

"Although many wizards think that knowing these stars is useless, what I want to tell you is that those are all wrong perceptions, and they are just the complaints of people who do not understand astronomy.

In fact, astronomy is a very useful subject. Compared with elective courses such as ancient runes, magical creatures, and divination, astronomy, along with spells, transfiguration, potions, etc., is included in the first-year curriculum. The required courses at the beginning are very reasonable arrangements. "

Professor Sinistra talked eloquently,

“In order to improve everyone’s motivation for learning, I decided to reveal to you a little bit about the usefulness of a subject like astronomy.

First of all, when we reach a certain level, we can get some inspiration based on the regular changes that occur when the stars move. The astrology used by wizards was invented based on this.

This is just a very simple application. Although the accuracy is not higher than that of prophets with divination abilities, it is still a good gain compared to ordinary wizards.

Of course, there are deeper applications, but I can't say much now, but I can demonstrate a little. "

As he spoke, Professor Sinistra pinched his wand and waved it hard, and suddenly a tiny galaxy composed of one star and nine planets appeared in the air. Harry remembered that this was what they learned in the last class. , that is the solar system, and the middle one is the sun.

In midair, the galaxy that occupies almost half of the top of the astronomical tower is slowly rotating according to Professor Sinistra's command.

The little wizards marveled, thinking that was the end of it, but instead of stopping, Professor Sinistra waved his wand even harder. All nine planets in the air disappeared, leaving only the little sun, and then the little sun. It expanded bigger and bigger, and the little wizard who got closer could feel the heat wave blowing in his face.

Just when the little wizards couldn't stand the scorching sun, it suddenly disappeared, and then the sky-blue Uranus appeared, and strong winds began to blow on the astronomy tower. The little wizards had to protect their telescopes to prevent them from being blown away. bad.

Not long after the strong wind blew, Uranus turned into Venus. The little wizards were very curious about what effect Venus would have, but after waiting for a long time, they found nothing until Professor Sinistra threw a pebble on Venus. As soon as the pebble came into contact with the atmosphere surrounding Venus, it was completely corroded, leaving no powder behind.

Professor Sinistra seemed to be very satisfied with this effect, and then Venus turned into a sea-blue Neptune. On the astronomy tower, the temperature dropped sharply. Several young wizards who relied on their physical strength and ignored the cooling at night and did not wear more clothes were all They hugged each other to keep warm when they were freezing.

Neptune didn't stay long before it turned into a dark, unresponsive planet. Harry wasn't sure whether it was Pluto or a planet in some other galaxy, because he had never seen a black planet in his textbooks. planet.

Professor Sinistra did not give an explanation. She waved her hand away and moved the planets in the sky, then said: "Different people can obtain different magic after in-depth study of astronomy, and what I am demonstrating to you is what I obtained. of.

If you like this kind of magic, then I hope you can get excellent in the OWLs exam in fifth grade, and then I can teach you all the things I just demonstrated.

Okay, that's the end of today's class. This week's homework is to write a paper about the solar system, at least 7 inches. Let's finish the get out of class. "

The little wizards were complaining. Apart from the flying class, which was taking place tomorrow and had no homework, there were seven compulsory courses for the first grade. The professors of almost every class would assign a bunch of homework. This was simply to make them So exhausted!

However, the biggest advantage of the little wizards is that they are forgetful. They quickly put aside the pile of unfinished homework and began to discuss the magic they just saw.

"That's really cool, isn't it, Harry." Ron excitedly led the way. Ever since Neville led him the wrong way and almost broke into the restricted area on the fourth floor, Harry and Ron had been taking turns leading the way. Tonight it's Ron's turn.

"Yeah." Harry replied absently.

"If I can be like Professor Sinistra and have a few stars surrounding me, then can I become the best player in the first grade?" Ron thought.

"Yeah." Harry's reaction was still a little flat.

"Harry, what's wrong with you? You've been in a daze tonight." Ron was a little confused.

"Yes," Neville said, "Harry, what's on your mind?"

"I guess he's worried that he won't be able to finish his homework, just like last week." Hermione secretly complained from the side.

"Then there's nothing to worry about. Neville will copy it for us after he finishes it first." Ron hugged Neville's shoulders matter-of-factly, "right, Neville?"

"I..." Neville looked hesitant to speak. He wanted to say that it was best to do his homework by himself. Moreover, he thought that his homework was a mess, but when he thought about being dragged by Harry and Ron that day, In the scene of running away, he couldn't say anything to refuse.

Ron pointed at Neville's nod and looked at Hermione with a proud look on his face.
