The Tianyan Research Center is very efficient.

After Mo Bai proposed the live broadcast, the Tianyan Research Center reached a cooperation with CCTV.

Of course, this can't be said to be how efficient the Tianyan Research Center is. In fact, the staff of the Tianyan Research Center only contacted CCTV, and CCTV has been in contact with the Tianyan Research Center 24 hours a day.

Yes.

That's right.

You know, what's the hottest right now?

It's not what the eye of the sky is.

The 500-meter-diameter Tianyan photo that was exposed to the light before shocked countless people.

At this time, it is said that it is a live broadcast, not to mention that CCTV has resources, even if there are no resources, they will draw resources.

Everything went well.

Although the time is tight, CCTV has urgently dispatched additional manpower, and a live broadcast program called "Star Hunter" has been launched.

Moreover, in order to increase the impact of this program, CCTV also inserted advertisements on several channels of this station.

Even in the news broadcast, the host also mentioned that at 8:30 p.m., the Tianyan Star Hunting program will be broadcast live.

"I'll go, Tianyan Research Center, do you want to be an Internet celebrity, and you actually live broadcast star hunting. ”

"What is a star hunter?"

"Stupid, it's just looking for pulsars. ”

"Pulsars, I know, are the stars discovered by the US Space Agency before. ”

"Yes. ”

"Awesome. A must-see for tonight's live stream. ”

Many fans are certainly not astronomy fans.

Many fans don't know what a pulsar is.

However, they knew that before that, the Chinese people had not even discovered a pulsar.

This also makes the US space agency laugh at us all the time.

But now, everything will be a thing of the past.

The god-like eye of heaven will show the most cutting-edge astronomical technology in China.

Time flies, and in the blink of an eye, half past eight has arrived.

Hundreds of millions of people stay in front of their televisions or computers, watching CCTV's live broadcasts.

"Here we go. ”

"Well, it's time, it's begun. ”

Everyone was glued to it.

CCTV was very punctual, and at 8:30, the Star Hunter program officially began.

"Welcome to the live broadcast of "Star Hunter" for you, I am the host Shen Bing. ”

This is Professor Li Guen, a well-known astronomer. ”

"Hello everyone. ”

A simple set of opening remarks by the two, and the entire live broadcast has begun.

"We put the picture on the Sky Eye Research Center. ”

"As you can see, this is the eye of the sky that was exposed in the media before. ”

"Judging from the video, I think this is more imposing than the previous photos exposed in the media. ”

The camera is aimed at the eye of the sky with a 500-meter caliber from a high altitude, although nothing is introduced. However, that majestic force came to the face.

"It's shocking, I didn't expect that our country would be able to manufacture such a national weapon. ”

"It can indeed be said to be the most important weapon of the country. ”

"By the way, Professor Li, can you tell us a little bit more about pulsars? Although it has been talked about in the media before, I don't think it's very clear. For example, what does the discovery of pulsars do for us, and why do we want to discover them?"

"It's actually quite simple. Let's talk about pulsars first, what is a pulsar will not be introduced for the time being. When it comes to introduction, I'm afraid everyone will have another headache. However, here's what you can know. Pulsars are called pulsars because they can emit periodic pulse signals. How to understand this periodic signal, you can refer to the lighthouse. We know that at night, the lighthouse by the sea is constantly circling in circles, and with each turn, we can receive the light emitted by him. A pulsar is like a lighthouse, and we can receive its pulse signal while it is constantly running. ”

"It turns out that this pulse signal is like a lighthouse, and I understand that. But why do we want to accept this signal, or what does receiving a pulse signal do for us?"

"That's a big deal. If nothing else, let's take astronautics as an example. As soon as our satellites, including rockets, are launched into space, our GPS positioning and navigation will not work. That is to say, when we are on Earth, we can also use GPS navigation and positioning to determine the location of our satellites and our rockets. However, once the satellite leaves the earth and enters space, GPS cannot be located, and we cannot rely on GPS to locate our satellite. ”

"So, what do we do at this time? The answer lies in the pulsar, because the pulsar sends out periodic pulse signals from time to time, and this signal is very stable. With these pulsars, we can locate ourselves in space. ”

"Oh, I get it. ”

The host Shen Bing nodded: "No wonder so many countries have been constantly looking for pulsars. ”

"Yes, it can be said that the more pulsars we look for, the clearer our positioning will be. The more pulses we find, the more accurate our positioning will be. ”

While the two were explaining, the camera also shifted from outdoor to indoors.

"Professor Li, can you tell us about the method by which Tianyan found pulsars?"

"Absolutely. ”

"Because Tianyan is a radio type telescope, his main role is not to see, but to hear. ”

"Listen?"

"Yes. ”

"Professor Li, you said that the eye of heaven hears, does the eye of heaven have ears?"

"Absolutely. ”

Professor Li nodded: "You see, those dozen signal towers are the ears of the eye of the sky. By receiving signals from the universe, we can find out which is a pulsar. ”

"No, no, Professor Lee. Do you mean that the signals of the universe include the cries of bugs, the sounds of thunder, and the sounds of people talking?"

"Yes, of course. But we can rest assured. Although our Sky Eye can accept these signals, through our system, Sky Eye can automatically block out these noises, and we only need to receive useful information for our Sky Eye. ”

"Of course, despite this, it's still a lot of work. ”

"Why?"

"Host, you think, we handle some signals on the planet very well. Because we know the earth, we know the properties of the earth. However, a series of signals from space, from the entire universe, would be too huge and huge. ”

"Professor Li, I understand what you mean. In other words, the range of listening is not only to pulsars, but also to other stars. ”

"Yes. The universe is so big that our starry sky has hundreds of millions of stars. Some we can see, some we can't. How do we find out who the pulsars are among these stars? To use an analogy, it's like a police officer catching a thief, with so many people on the road, how do you determine which one is the thief crossing the street?"

"In this way, it's kind of like looking for a needle in a haystack. ”

"So to speak. ”

Li Guen nodded.

At the same time, there are some worries in my heart.

Generally speaking, it takes at least a few months from the search for a pulsar to the discovery of a pulsar.

Sometimes even years, even decades.

Especially the millisecond-level pulsar, because his pulse signal is measured in milliseconds, it is a headache for countless astronomers.

Li Guen didn't know.

For a job like this, he should secretly catch it himself.

This is certainly not to say secrecy.

The problem is, it took ten and a half days and a half to capture this capture, could it be that this live broadcast would also follow the live broadcast for ten days and a half months?

What's more important is that if you can't catch it in ten days and a half months, you must not die of embarrassment.
