"Three ...... of the South River"

At this time, Yang Meng recalled a lot of information about Nanhesan,

As a binary star system,

Nanhe-3 is composed of a sub-giant star, Nanhe-3A, and a white dwarf, Nanhe-3B.

This kind of stellar structure is nothing.

Sirius, located 8.6 light-years from Earth,

It is also a binary star system consisting of a star plus a white dwarf.

So, such star systems are not uncommon in the universe.

As for the special celestial body in Nanhe III - the white dwarf.

It is not the main reason that prevents him from going to Nanhe San. ，

On the contrary, white dwarfs are very stable objects compared to stars.

If there is only one white dwarf star in the Nanhe three-star system, his return path will definitely pass through the Nanhe three.

After all, white dwarfs are just corpses of stars after they die,

As a corpse, it should lie there peacefully!

Of course, there are also some stars that struggle to bring obscurity to their surroundings after they die, such as black holes!

And the real reason for Yang Meng to avoid Nanhesan,

Or the main sequence star of Nanhe III, Nanhe IIIA:

"This star is about to enter the end of its stellar life,

Whether there is life in the Nanhe three-star system or not, it doesn't matter to human beings! ”

This is the evaluation of Nanhe San by the decision-makers of the Human Pioneer Exploration Program.

The reason why it doesn't matter is because when a star enters the end of its life, a lot of phenomena happen.

According to the mass, Nanhe 3a should be classified as a yellow dwarf star like the Sun.

But it is classified as a subgiant by some astronomers,

This is because Nanhe San entered the end of his life and began to expand.

Over the next 10 million years,

Eventually, it will swell to 80 to 150 times its current size, become a red giant, and then die, leaving only the white dwarf as a corpse, and the other white dwarf in its own galaxy.

According to the simulation calculation,

The same is true of the end of the solar system,

When the Sun enters the terminal stage of the star, there is also a high chance that it will become a red giant and eventually a white dwarf.

And the reason why stars change like this,

Or is it because of the change in its own "fuel",

The main element that stars burn at the beginning is hydrogen.

The ash produced by the "combustion" of hydrogen is helium.

Helium can still be "burned" by fusion reactions! ”

However, compared to hydrogen, which has a mild temperament, helium has a wilder temperament.

Without a certain physique, the helium element is simply suppressed,

If the physique is not enough, and you force the helium element, not only will you not take much advantage in the end, but you will also be kicked away by the helium element that resists fiercely, and finally you will die of redness and swelling!

Unfortunately, stars of the Sun level can't suppress the existence of helium.

And the kick kicked by the helium element also has a resounding name - helium flash.

Helium flash! As a powerful storm of stellar particles,

If there is a helium flash in the sun,

Humans can only drive the earth to wander.

Fortunately, the scope of helium flash is limited, and the only way to avoid the impact of helium flash is to avoid the impact of helium flash if it does not enter that galaxy.

The short history of astronomical observations of mankind cannot determine whether the Nanhe Sana, which has begun to be "red and swollen", has undergone a helium flash.

If it hadn't been carried out, then Nanhe 3A would be a huge time bomb.

If it has been carried out, it should not be taken lightly,

Because the combustion of helium is not sufficient, it can lead to an accumulation effect.

A secondary helium flash can occur at any time. And the entire South Gate Samsung system is in such a state,

This is also one of the real reasons that prevented Yang Meng from going to South Gate Three.

"No matter how you say it, the Rutan system has seven planets, and some planets have their own moons!"

"Should be able to gather enough resources to repair the ship......"

At this moment, Xiao Yi's voice sounded in his ears:

"It's on track!"

"Attention! According to the fast docking technology,

It is expected to dock with the ship's core module in 37 minutes! ”

Hearing Xiao Yi's voice,

Yang Meng's thinking has returned to reality from the three-star system in the south gate.

I saw him silently close the star map,

Looking at the porthole on the side,

At this moment, the small light still floated in front of the porthole, as if the scene of outer space could not be seen enough.

"This should be the first time he has seen space in sight!"

Feel the familiar weightlessness environment,

Yang Meng untied the safety restraints on his body and slowly floated up. His right hand gently pushed his seat,

The whole person floated in the direction of the porthole.

When you come to the porthole,

Yang Meng of the entire Rutan B planet is clearer,

Under the light of Rutan, Planet B is a completely red planet to the naked eye of humans:

"This is your planet!"

"Yes! We live here! ”

"That's right! What is the planet you live on? ”

"It's a planet with a blue star."

"Blue, what a rare color!"

……

With a wordless dialogue,

Yang Meng and Xiaoguang floated in front of the porthole and looked at this strange Rutan planet.

Thirty-seven minutes passed quickly.

The living module has finally come to the front of the core cabin,

Through the image sent back by Xiao Yi, Yang Meng saw the spaceship in bulk at this time,

Compared to the complete appearance of a spaceship on the ground,

The makeshift spacecraft, which is made up of the core module and other important parts, looks very cluttered, like a large space station from his grandfather's time.

And the next docking part, you just need to wait for the program to complete automatically.

"The robotic arm is connected!"

"Docking in progress......"

"Docking complete!"

"Detecting ......"

"The connection is working!"

"The cabin environment is normal!"

"You can open the hatch!"

Hearing Xiao Yi's voice, Yang Meng sorted out the equipment on his body,

glanced back at Xiaoguang behind him, and saw that Xiaoguang was still in front of the porthole, and Yang Meng didn't pay attention to it.

He has a lot of work to do.

Whatever the state of resources in this galaxy,

He had to do some preliminary assembly and maintenance of the ship before he could move on to the rest of the business.

However, when the maintenance was carried out in the communication cabin, Yang Meng got a piece of bad news for him personally.

"Xiao Yi! Do you mean that the data of our communications with the Earth has been lost? ”

Looking at the large communication device in front of him, Yang Meng's face was a little unsightly.

"Due to the loss of storage energy, the storage media has been restarted, and most of the non-important communication data has been lost!"

"That's not unimportant data!" Yang Meng silently retorted in his heart, but he didn't argue with Xiao Yi about anything.

After all, as an artificial intelligence, Xiao Yi can't understand what those unimportant data mean to him.

In the nearly 100 years since he left the earth, he has not completely lost touch with the earth.

Instead, they communicate at regular intervals.

Every year, the earth will change the various changes that occur in human beings.

and news of his important relatives and friends,

Passed to him by means of a cluster signal packet,

But what he didn't expect was that these data that stole his emotions were lost.

"Xiao Yi, when is the next cycle of communication?"
