Chapter 747 Planetary Defense Conference

"The Orion λ star, among the Chinese constellations, belongs to the 28 constellations, and it is located above the middle of Betelgeuse and Betelgeuse, with an apparent magnitude of 3.39..."

Lang Tongguang continued to talk about astronomy: "The apparent magnitude is the level of a star visible to the naked eye. The smaller the value, the clearer you can see it, and the larger the value, the dimmer the star.

"In a clear and clear night sky, under normal circumstances, the visual magnitude visible to the human naked eye is 6.

"That is to say, the star Lambda Orionis is visible to the naked eye.

"However, the premise is that the night sky is clear and clear. The modern night sky is relatively bad, so sometimes it is not easy to see stars of magnitude 3.

"Let's continue to look at the surface map of the star beast mother star synthesized by the computer. This is what the star beast mother star looked like a thousand years ago. Let's see what is special about it."

Fang Yuan observed carefully for a while, and replied: "There is no Deep Wind Rift Valley."

Lang Tongguang nodded in satisfaction, and said, "I remember that your military scientific research team has been to the Deep Wind Rift Valley, right? That's right, there is indeed no Deep Wind Rift Valley on this planetary map.

"The reason why the Deep Wind Rift Valley is not on the map is not because it couldn't be photographed, but because it didn't exist in the first place. It can also be seen from this point that the Deep Wind Rift Valley didn't exist a thousand years ago, and it was created later.

"As for the reasons for the formation of the Deep Wind Rift Valley, if you are interested, you can look up the information yourself, so I won't talk about it here."

Regarding the reasons for the formation of the Deep Wind Rift Valley, the students of the military research class who have been to the Deep Wind Rift Valley all know.

The Deep Wind Rift Valley was crashed by Rahu's Halo-class aircraft that descended upon Civilization when it made an emergency landing.

Regarding this content, there is still a classified level, and it has not been declassified, so Lang Tongguang did not continue.

Next, Lang Tongguang explained some content about astrometry.

At 9:40 in the evening, it was announced that get out of class was over.

After class, Fang Yuan ran into He Minghao again on the steps in front of the building.

"You should be the reason why I joined the military research class, right?" He Minghao took the initiative to speak.

"Well, I heard." Fang Yuan replied casually.

"Whether it is the future of the country,

Neither the fate of human beings should be placed in the hands of one person. You should be able to understand this. "He Minghao put his hands in his pockets and tried his best to express his kindness, but there was still a sharp edge in his eyes.

"I'm just curious, when I went to the report last time, it seemed that some people didn't join the military research class because they said they didn't like being in the army, now this is 'really fragrant'?" Fang Yuan grinned.

He Minghao frowned, although he could hear that he was teasing, but as the object of teasing, he couldn't be happy at all.

Moreover, he did say that he didn't want to join the army, so he didn't enter the military research class.

Now that I have entered the military scientific research class again, it is indeed really fragrant.

"The school leaders talked to me and chose to send them over. Of course, I did agree..."

He Minghao looked up at the sky and sighed: "Sometimes life really can't be done according to my own wishes. In fact, joining the army is really not my ideal state. But the elders and mentors all think that the country needs me, so I have no choice but to shoulder this responsibility .”

"Then I wish you success, sincerely." Fang Yuan said with a smile.

"Fair competition. I think our goals should be the same." He Minghao raised his fist.

Fang Yuan could tell that the other party was about to graduate from university, and his thinking was mature, so there was no problem in his position, first he was on the side of the country, and then he was on the side of human beings.

In principle, the two sides are in agreement.

As for the competition, in the crisis era of the earth, whoever is stronger will win, this is the most correct choice.

Both sides lightly punched each other, then turned and left.

...

the next day.

The Planetary Defense Conference is held in the East China Sea.

The meeting place is at the Planetary Defense Council Building in Donghai City.

Two weeks ago, the Eastern Navy Academy of Sciences released some evidence of the existence of the meteorite civilization, and indicated that the meteorite civilization left a piece of information.

This is the third civilization known to human beings after encountering the civilization of star beasts and the civilization of Palesi's soul descending.

Moreover, this civilization left messages.

This news is earth-shattering news for all countries on the earth.

Therefore, this planetary defense conference, almost all countries that can be named have come to participate.

The military scientific research class sat in the northeast corner of the conference hall. There were 38 people in the class, and most of them came.

The five members of Fang Yuan's team formed a small group, and they were talking softly before the meeting started.

Representatives from various countries entered the venue one after another.

At ten o'clock.

Fang Zhenguo came to the stage on behalf of the headquarters, took a document, put it on the podium, cleared his throat and began to say: "Representatives, welcome to Donghai, to participate in this planetary defense conference..."

After the opening speech, a representative from another country asked a question: "Two weeks ago, you released news that there was a civilization in the solar system. Is there any evidence?"

"Don't worry, today's meeting is about this matter, please watch the big screen." Fang Zhenguo clicked the remote control of the presentation.

A star map was released on the big screen, showing the solar system.

Regarding the star map of the solar system, everyone is very clear, basically it can be seen at a glance.

Fang Zhenguo illuminated a place with a pointing ray, and said: "Everyone should know that this is the asteroid belt of the solar system, where more than 600,000 asteroids have been discovered. According to scientists' estimates, all asteroids and cosmic dust combined , will exceed 20 billion.

"The meteorite civilization we announced is in the orbit of the asteroid."

After saying this, there was immediately discussion on the scene.

Since this meeting involves astronomy, delegations from various countries have brought domestic astronomers here.

After discussing for a while, Koji Kawamura, the representative of the island nation, raised a question: "According to our astronomers, the total mass of all the asteroids in the asteroid belt is not as large as that of the moon. It is impossible for a civilization to exist in that location."

"I don't know what you know?"

Fang Zhenguo glanced at him, blocked him with one sentence, and then continued: "I don't want to repeat the speculation about whether there are planets in the asteroid belt, I only talk about the key content of the meteorite civilization.

"The information left by the meteorite civilization shows that they were attacked by a high-level civilization called the Cleanser civilization. This information was left over ten days before the civilization was destroyed.

"This piece of information has a total of more than 20,000 words, recording the general situation of the meteorite civilization, and the process of being attacked by the cleanser civilization, and finally left a warning.

"From the information left by the meteorite civilization, we can know that the meteorite civilization is a carbon-based civilization that lives on an terrestrial planet, and the orbit of this terrestrial planet is near the asteroid belt."
