The vast universe is extremely vast, with a diameter of 100,000 light-years, just one of the most inconspicuous ordinary existences. The Centaurus galaxy located on the Orion arm of the Milky Way is very close to the Sun galaxy. The distance of 4.3 light-years is inconspicuous at all in the universe, and the two galaxies are as close as if they are stuck together.

However, even at this inconspicuous distance, it will take more than 20 years for humans in the solar system to reach the current technology. The universe is really vast and humans have come to galaxies outside the solar system for the first time.

"Explorer 1" is the first spacecraft among the Explorer System spacecraft and the first spacecraft to be launched. It was built in order to explore the alien galaxy universe civilization during the Qingquan Technology period. At that time, a total of a series of Explorer spacecraft were built, all of which were launched to the star system closest to the solar system.

"Explorer 1" was launched to the Centaurus galaxy closest to the solar system. After sailing at 0.2 times the speed of light for more than twenty years, it is finally about to arrive in Centaurus.

4.3 light years away in the universe, the "Explorer 1" has been fully awakened at this time, and various exploration instruments are fully opened. The original communication with the earth was only once a week because of energy issues. Now all work has begun, sending all information to the control center in the solar system through quantum communication technology!

Thanks to advanced communication technology, "Explorer 1" can be connected in real time with the control center far away in the solar system. Otherwise, if you rely on traditional electromagnetic wave signals, this one-way communication will take 4.3 years at a time, and it will take 8.6 years to interact with each other. Communication technology is as important as transportation technology, otherwise it will be difficult to move in the vast universe!

"Explorer 1" is still one year away from Centaurus at this time, but the light of the three stars in Centaurus is already very dazzling at this time, and the light of the solar system behind it is already very weak. It is difficult to find it among the stars in the sky without deliberately searching.

"Drip~Drip~Drip~Drip~"

Various instruments on "Explorer 1" are fully opened. The electromagnetic wave receivers in them receive very strong and obviously regular electromagnetic signals, and immediately start to receive these signals. At the same time, other instruments also begin to detect the centaur in a targeted manner.

Centauri α is a three-star system, the closest star system to the sun. It has three stars, its numbers are A, B and C. Among them, C in Centauri is named "Proxima".

The "Explorer 1" with all kinds of instruments quickly transmitted data back to the control center far away in the solar system. At this time, the control center in Mars space in the solar system was also crowded with people. Scientists from all walks of life, including the Imperial Emperor Liu Qingquan, had all rushed here at this time.

According to the news sent back by "Explorer 1", there are obvious and regular electromagnetic signals in Centaurus, and there is only one reasonable explanation for the ability to generate such electromagnetic signals, that is, there are also civilizations similar to those in the earth's civilization!

Naturally, the news quickly spread throughout the empire, and all interested scientists flocked here to obtain more detailed information as soon as possible.

The control center hall was filled with people, and famous scientists and nobles of the empire were discussing casually without any image at this time, discussing what kind of civilization the Centaurus civilization would be, what level of technology would be? What would their attitude towards human civilization?

Liu Qingquan, who is over 50 years old, looks no different from that of decades ago. His profound Yuanli cultivation gives him a long life span. He can't leave any traces on him at all. However, those who do not work hard to cultivate Yuanli are a little old at this time.

"Boss, what do you think of this Centaur civilization?" Jiang Zhipeng, who is also in his 50s, looks very young at this time, and is still called Liu Qingquan as he did decades ago. This seems to be the privilege of their generation. After all, Liu Qingquan is still the emperor of a country at least, and such a name is too big or small.

"I don't have a clairvoyance, so how can I know? But being able to use electromagnetic wave communication technology means that the level of civilization should not be low!" Liu Qingquan shook his head, and he had been looking forward to the civilization of Centaurus for a long time. Although he had known that civilization is common in the universe, it was the first time he had really come into contact with it.

"It's better to have a higher level of civilization. Sometimes we need to communicate more when developing this technology. There must be nothing to communicate with primitive civilization. We can't learn how to use grinding stone knives!" Mo Qingming, who was also very casual on the side.

"It's not okay if the level of civilization is too high! Our technological level can only be considered a level 2 cosmic civilization. In the universe, we can't even fight five scumbags. Anyone can come out can completely defeat us!" Someone immediately objected. When he looked back, he turned out to be Chen Shuiwa, the child from the Loess Plateau, who is now in his 50s.

"Where can there be too advanced civilization around the solar system? If there were, we would have been captured long ago!"

"Our technology can develop rapidly, but it is hard to guarantee that others can do it too. Maybe they will run ahead of us!"

“…”

Liu Qingquan shook his head and looked at them quarreling around. It was obvious that everyone was concerned about the result. One was their level of development, and the other was their attitude towards alien civilizations.

This is how universe exploration is. On the one hand, I hope to encounter civilization, and on the other hand, I am also vigilant enough about it. This is the attitude of human beings towards unknown things, both curious and afraid!

Without participating in the debate between them, Liu Qingquan looked at the screen in the hall attentively. At this time, "Explorer 1" far away from the 4.3 light had already sent back a large amount of information, among which the basic information of Centaurus can be clearly known.

Among the three stars in Centaurus, A and B have similar mass to the sun. They are attracted to each other and are relatively stable. They are early, but have entered a stable period. The star closest to the solar system, which is the star we call Proxima Centauri, has a mass smaller than that of the solar system, only one-seventh of the sun, and is about the same size as Jupiter!

Proxima Centauri is a red dwarf with a surface temperature much lower than the solar system, only more than 3,000 K, which is more than 2,700 degrees, but there is a planet very close to it!

In 2015, astronomers used ESO's astronomical telescopes and other facilities to discover that there was enough evidence to prove that a planet existed in the stellar system closest to Earth (ProximaCentauri).

This long-term observation world, named Proximab, orbits its red dwarf parent star in 11 days, with appropriate temperatures on the surface to maintain liquid water. This planet is slightly larger than the Earth, and is the closest extraterrestrial planet to Earth, and may also be the most likely life outside the solar system.

In other words, in 2015, astronomers on Earth had discovered the planet of Proxima Centauri, and by man-made it should have liquid water, it is inferred that it is most likely to have life!

But in fact, according to the information sent back by "Explorer 1", "Proxima Centauri" captured that there was no life on the planet. This planet is a complete death star without any vitality.

The electromagnetic signals captured by "Explorer 1" do not come from here, but from the middle area of ​​the other two stars, which everyone believes are the least likely to exist in life.

When talking about this, I will first talk about the two stars A and B. The mass of A is slightly larger than that of the sun, and the mass of B is slightly smaller than that of the sun. The distance between the two is about 10 astronomical units.

Among them, A is of great mass and has captured 4 planets by relying on its own gravity. B also has 3 galaxies. However, the electromagnetic signal does not come from these 7 planets, but from the gravitational translation point between the two stars, that is, the position of the Lagrangian point.

I have to sigh at the magic of the universe. The mass, volume, etc. of this planet are much larger than that of the earth, about 10 times the mass of the earth! It is about 6 astronomical units from Star A and 4 astronomical units from Star B. It is just pulled by the gravity of the two stars A and B. This is a planet without an autobiography!

Yes, this is a planet without autobiography. The huge gravity of the two stars completely controls the planet. Because there is no autobiography, its gravity should have been relatively small, but its mass is ten times that of the earth, which just makes up for the defect of insufficient gravity because of the lack of autobiography. In fact, its gravity is similar to that of the earth. After all, where is the mass?

Originally, it is impossible to produce life based on the position of this planet from the star, but because it is illuminated by two stars and is always illuminated by two stars, its surface temperature is very suitable for the birth of life, neither high nor low!

It is far away from the stars, and the temperature will not be too high. At the same time, it is constantly illuminated by two stars, and the temperature will not be too low. The average temperature of this planet is about 20 degrees, which is a very comfortable temperature!

Because it is not autobiographical and is subject to continuous light from two stars, unlike the earth, the cold zone here is a north-south circle. This cold zone divides the planet into two worlds, the side illuminated by star A and the side illuminated by star B.

As more and more electromagnetic wave signals are received and the progress of signal decoding work is made, everyone knows that this planet is called "Blue Riding Star" by the civilization here!
