"I'll go, what is this?"

"What a big pot. ”

"It's not for stir-frying. ”

As soon as the Tianyan photo appeared, the eyes of the spectators were instantly stunned.

"I said, it's like looking at glasses. ”

"Yes, it must be the glasses. ”

"Look, this is the Arecibo glasses of the United States, the eyes of heaven are almost the same as his, but they are bigger. ”

"Nima, take a cursory look, the diameter of this telescope must be at least 500 meters. ”

"No, 500 meters of glasses, this and this...... Is this technology from Mars?"

"I don't know if it's Mars Technology, but I know that this can definitely beat Arecibo in the United States. ”

Although the official has not announced what this Tianyan is, countless fans have been enthusiastic.

……

"Everyone, how about it, I'll just say that as soon as we make a move, Hua Guo won't even dare to speak. ”

"That is, we dare not say that in other industries, if we talk about astronomy, there is a difference of 200 years between China and us. ”

"Don't be proud, we have to continue to work on it, and we will continue to expose some content next month. However, remember, the content of the exposure is seven percent true and three points false. We have to shock their eyes, but we can't share the results of our research with them. ”

"Definitely. ”

Several researchers from the National Space Agency were in a good mood and clinked glasses from time to time.

"No, guys, there's bad news. ”

"What's the bad meaning, I said Anda, don't be like this all the time, the aliens didn't attack Earth. ”

"Yes, Boss, it's true that the aliens didn't attack Earth, but Hua Guo's side announced their latest glasses. ”

"Hey, did they make a lookout glasses too?"

"Yes. ”

"What type?"

"Radio glasses. ”

"It seems that they want to fight with us in the ring, what are the parameters, and what is the caliber?"

"The specific parameters are not known for the time being, but the caliber, we estimated it in rough steps, it should be about 500 meters. ”

"What, 500-meter caliber?"

"Yes. ”

"Anda, you're not drunk today, are you? ”

"Boss, I didn't drink today. ”

"Then how do you say the caliber of 500 meters, do you know, how big is more than 500, he is as big as 4 football fields. ”

"Boss, look. ”

Seeing that the boss didn't want to believe it, Anda immediately took out the printed information.

Looking at the oversized goggles installed between the lofty mountains, all the researchers on the scene were directly blinded.

"Oh my God, that's too big. ”

"Is this really the glasses made by Huaguo?"

"No, it can't be, there can't be such large-caliber telespectacles in the world. ”

"Yes, even if the latest telescopes made in Europe are only more than 100 meters, how can China have the technology to make a caliber of 500 meters?"

"This must be P-picture, it must be. ”

Several people kept shaking their heads.

It's just that, after ten minutes of refusal, they gradually became silent.

Looking at the glasses on the map, they knew it was true.

Yes.

Is it PS that they can see at a glance.

Moreover, from all aspects of the picture above, it can be proved that this must be a super-large telescope.

Reflective surfaces, signal towers, including cable net skeletons......

All of this proves that this oversized telescope is real.

Not only is it true, but it has been determined to be pure radio telescopes.

"What should I do?"

Everyone, you look at me, I look at you, and there are some unacceptables in my heart.

You know, they have just announced the discovery of pulsars to the world.

And, with this news, their Arecibo also shocked the world.

But the reality is so cruel.

When they thought they were the number one in the world, Huaguo followed up and announced a bigger glasses than them.

No, not just bigger, but ten times their super telescopic glasses.

Compare the two with one another.

If the previous Arecibo is still the world's top glasses.

Then, the current Arecibo can only be regarded as a beginner's glasses.

"Don't look at me, I don't know what to do?"

After speaking, the deputy director of the National Space Administration of the United States seemed to feel that this was too demoralizing for his side, so he said: "Actually, we don't have to be so shocked, the comparison of the glasses is not the size of the caliber." It is not that which glasses have a larger caliber will be stronger. ”

"Let's wait a minute, look at the specific parameters announced by their Huaguo, and then we will analyze it. ”

"Well, that's all for today's meeting. By the way, let's get together less in the future. ”

The deputy director put down his glass and left directly.

What was left behind was a group of dumbfounded scientists.

……

"That, why did the official only release a picture and not explain it. ”

"By the way, is this cauldron a sight glass?"

"This is too big, if it's really looking at glasses, it can simply beat the United States. ”

"Didn't some experts confirm it?"

"Although various experts have confirmed that this is definitely radio telescopic glasses. And it looks like he must be better than any of the glasses in the world, but if it is not officially announced, I always feel bottomless in my heart. ”

"Me too, looking forward to the official announcement of the answer as soon as possible, and let's get excited. ”

The Chinese people are looking forward to it.

Of course, the officials didn't make everyone wait too long.

The next day, the Yunnan-Guizhou Provincial Authorities officially announced the answer.

Yes.

That's right.

The big iron pot that was announced yesterday is indeed a radio type telescope.

In addition, the official also named this telescope "Sky Eye".

In addition, the official not only officially announced the answer, but at the same time, the official also announced some performance parameters of Tianyan at this time.

1. Ball reflective surface: radius - 300m, diameter - 500m

2. Effective lighting caliber: 490m

3. Focal ratio: 0.467

4. Sky coverage: zenith angle 40°

5. Working frequency: 70MHz-3GHz

6. Sensitivity (L-band): 20000.

Well, it should be said that most people can't understand this performance parameter.

However, everyone can't understand it, but naturally some people can understand it.

"Ou Shuhua", an expert who has been studying astronomy, opened a blog and explained in detail the major parameters of the eye of the sky.

First, in terms of caliber, Huaguo's caliber is 500 meters, while Mi's Arecibo is only 50 meters, which is more than 10 times his size.

Second, you may not be able to understand it from the perspective of caliber alone. So, let's talk about effectively observing the target. Compared to the largest telescopic glasses in Europe, the Sky Eye is 300 times that of him. As for the comparison with Arecibo in the United States, it is 100 times. In other words, the world's most powerful telescopes can only see a small part of the universe, or can only receive signals in a small range. And now Tianyan has increased this range by 300 times.

Third, in terms of sensitivity, the sensitivity of the eye is 20,000, the sensitivity of the largest telescope in Europe is 200, and the sensitivity of Arecibo is only 1000, which is dozens of times more than them.

Fourth, in terms of comprehensive performance, Tianyan will be 200 times that of the largest telescope glasses in Europe and 100 times that of Arecibo.

Fifth......

Forget about the fifth.

Don't look at the fifth, everybody.

As long as you look at the previous points, hundreds of millions of Chinese people are completely sensational.

"I'm grassy, I'm sloppy, I'm hasty. ”

"I always thought that Arecibo in the United States was an alien technology, but now that I look at it, it's just a beach. ”

"In other words, a few days ago, they used this to pretend to be a slap in the face, saying that our Huaguo is 200 years behind them in astronomy. I think they should be talking back, it's right that the United States is 200 years behind us. ”

"I just want to know how NASA feels right now. ”

"Hahaha, I want to know too. ”
