The glow of the brilliant Orion Nebula in the distance, spanning four light-years, is as bright as day behind the ship's porthole.

Zhang Jingyuan and other "old people" sat at the back of the hall and generally did not speak; Some of the young people ahead are very active. A huge, 20-metre-square projection of the starry sky, now shows the eight main bright "stars" of the entire constellation Orion. Seven of them are particularly bright, but the top one is a little dim.

A middle-aged-looking man was preparing to explain. Of course, in today's Huaxia, people cannot be judged by their appearance, and they may look like young people, but they are actually old monsters -- the typical representative is the big boss.

Obviously, this situation has made the comrades of the civil affairs department and the public security department very annoyed, and this annoyance has not ended until now.

Far away......

"Hello everyone, my name is Zhong Xinghui, just like my surname, I am from the Zhong family. Today, I'm going to talk to you about the Orion Nebula that we've detected; In the face of this unfamiliar interstellar environment, everyone must be prepared. ”

When Zhong Xinghui introduced himself, he was very proud! Also, as one of the most powerful families in the Chinese Empire today, it has the merit of being a dragon. From the construction of the Space Mirror back then, to presiding over the Space Environmental Science and Technology Research Department to promote the development of the empire, to the future exploration of the starry sky, the Zhong family is indispensable. Now, exploring new and unfamiliar star fields is indispensable for the elite of this family.

Also, with merit and dedication. This family has been able to retain their marquis title to this day! You must know that the Chinese Empire adopted a hereditary system, which can be imagined as strong as this family. Even around the solar system, they even have their own galaxy, their own country!

For a national structure like the Chinese Empire, the Pearl Star Domain has also been explored, but it can't be learned! In the rear of China's ancestral land, each galaxy is a country; But in the forward, combined into a huge empire, work together! This is a social structure that is very well adapted to the existence of the universe. Everyone has their own interests, and they can also protect their own interests; And at the same time. The whole race has its own goals to pursue!

Now. This family, which has always taken starry sky exploration as its own responsibility, has let the most elite generation of the family come to assist in the development and development of the empire.

Everyone was sitting in danger, Zhong Xinghui's explanation. It contains all the efforts and achievements of this family. Of course, it will also become the key and guidance for Huaxia's exploration of the Orion Nebula.

See everyone is ready. Zhong Xinghui turned his head and began to explain.

"In our ancient Chinese history, Orion was called Betelgeuse. Reading shen, xiu, ginseng is actually three, capitalized three, the reason is very simple, just look at the three stars in the belt of Orion.

According to the naming of our ancient culture, from top to bottom, the first is two relatively wide positions, the upper middle, there is a not too bright star, this is the Su, as the name suggests, on the hunter pattern of Orion, the position of this star, just on the mouth.

Next red, on the right shoulder of Orion, is a red giant star with a diameter of about 1.6 billion kilometers, almost a little more than the orbital diameter of Jupiter. Red giant, this is the later stage of the star, and it may evolve into the next nebula.

The red giant star was named in ancient China, Betelgeuse.

Next on the left shoulder is Betelgeuse.

And there are three juxtaposed on the belt, which are Betelgeuse one, two, and three.

Below, on the hunter's knee, are Betelgeuse on the right knee and Betelgeuse on the left knee.

First of all, I want to popularize a little astronomical knowledge to everyone. Many people only know that there is a constellation Orion in space, but few people will pay attention to the fact that from our point of view, many stars are actually in the wrong position.

For example, this red giant star Betelgeuse, which does not belong around the Orion Nebula at all. Orion is about 1,500 light-years from the Solar System, while the red giant is only 430 light-years away.

There is also Betelgeuse, which is about 770 light-years away from the solar system.

After talking about these two examples, let's talk about Betelgeuse, this star, which is actually a group of stars, has only recently been explored, and it is 80 light-years away from Betelgeuse, 223, which is the position we are about to reach now (no specific information was found). Betelgeuse is also about 70 light-years away from the nebula, which is a super-blue giant.

Having said all that, I would say that the Orion Nebula, which is our target, is actually Betelgeuse. The star we see in our solar system is actually a nebula with a diameter of 16 light-years!

But we should note that the Orion Nebula is not one, this entire star field, within a radius of two hundred light years, is all a nebula group! Just like the white clouds in the sky, although they seem to be isolated, they are actually inextricably linked, like ribbons.

According to what we have observed so far, what we have been observing is this 16 light-year diameter nebula, which is also the closest to us, and it is also the smallest one in this nebula group.

And behind, there is a large nebula with a coverage of up to 50 light-years.

At the moment, we have detected several danger areas in the nebula, which are those that appear to be particularly bright. ”

"Is it a star that just exploded?" An anxious officer suddenly asked.

"No, quite the opposite, they died at least 3 million years ago!" Zhong Xinghui has a rare sense of humor!

"In 3 million years, the temperature should have dropped, right!?" The officer was puzzled.

"Because they're now in the resurrection phase again!"

“？” The star is dead, but can it be resurrected in the same place? Many people looked at Zhong Xinghui, waiting for the other party's explanation.

"Yes, you heard it right, they are indeed in the resurrection phase. But the resurrected ones are not stars.

As you know, in ghost stories, it is zombies and not people who are resurrected. Similarly, the resurrected star is no longer a star, but a product of the star's death, a black hole!

Black holes, in everyone's understanding, must be the kind of existence that has no light and cannot be explored. For example, the black hole in the Pearl Star Field. But everyone is wrong, black holes also have several stages.

The black hole in the Pearl Star Field is in a stable period, and there is no matter around it that can be swallowed. But the black hole here is in the growth period. They devour the matter around them.

In the process of black hole engulfment, it will lead to the compression of energy, light, and some hydrogen, helium, and even lithium. These elements are compressed to the limit, causing an explosion of nuclear fusion reactions, which in turn release high temperatures and rays.

So those bright regions that we're seeing now are actually black holes, and they're black holes in the process of eating! Its area of influence is about one light-year to one and a half light-years. To be on the safe side, don't enter if you're 2 light-years away from the luminous circle. According to theoretical calculations, the luminous sphere is the extremely compressed nuclear fusion reaction region, and the distance from the black hole here will not exceed 500 million kilometers.

In addition, we should also note that there is another characteristic of nebulae, and that is radiation! Its radiation is completely different from that of a star. We know that the radiation of stars is directional. But the nebula is not, but from all directions! Maybe you see a fist-sized wreckage with a lethal dose of radiation.

To be precise, a nebula is also a celestial body, and if we want to enter the interior of this celestial body, then of course we will be attacked from all directions, that is, radiation. It's like the immune system in our body.

And around those black holes, the radiation is even more intense.

The composition of radiation here is very complex, there are ordinary ray radiation, strong electromagnetic wave radiation, and even particle stream radiation! What neutron rays, gamma rays, beta rays, alpha rays, X-rays, etc., just as much!

People say that roses are beautiful but thorny; And the current nebula is the rose in the universe!

Okay, now that I'm done, what do you have to ask? ”

"Hello Professor Zhong, I would like to ask, at present, we have detected strange life in the nebula, what is the explanation for this? You know, our existing scientific theories can't explain this phenomenon! ”

"Nice lad. Unfortunately, I'm an astronomer, not a biologist. Okay okay, I think you're skewed!

I don't think it's possible to say that our current theories can't explain this phenomenon; It should be said that our theory is about to make a big development again! This shows that carbohydrates, or silicon-based, are not necessarily inevitable for the development and evolution of life.

You see, in this universe, there is such life, they use nebulae as their bodies, planets as brains, and electromagnetic radiation as nerves. Wow, this is a treasure trove!

How fortunate we human beings are, when our development has slowed down somewhat, we have encountered such a miracle!

It's a miracle! Is it? It's a miracle, lad! We are lucky! ”

Finally, Zhong Xinghui emphasized that this is a miracle.

"Yes, Professor Zhong, you are right, this is our nebula, a miracle, a miracle facing us!"

"Okay, what's the young man's name? Would you be interested in becoming a researcher under me? ”

"Willing to teach. My name is Xiaohao! The size is small. "The young man has a tiger's head.

"Small? Oh, that's a rare last name. You'll have a month to pack it up, and then report to the Nebula 7 spacecraft. You'll find me then. ”

"Thank you, Professor!" Xiao Hao happily rolled all the way out of the conference hall.

"Hello Professor Zhong!" A middle-aged officer stood up, "I want to ask, will such a strong radiation of the Orion Nebula affect exploration and affect our safety?" ”

"For the time being, we found that virtual physical technology and energy protection layer technology, combined use, can isolate all damage. But only for the present time to explore. ”

"Thank you!" (To be continued......)

PS: Extra: Professor Zhong Xinghui quietly asked Xiaohao: Young man, will you warm the bed?

Xiao Hao smiled shyly: I have made a good friend, and he has always let me learn to sleep on the floor.
