Mikoyan was at the Space Observation Office at this time.

The old man who spoke at the conference before had already obtained all kinds of data after the cicada-class 004 boarded the alien spacecraft.

And a large number of astronomers are studying this data.

Dr. Mikoyan asked, "Ivan, what do you think?" ”

The old man hurriedly analyzed the data, and replied casually: "45300~45400 years, you can basically lock the starting time of this spaceship, plus the direction of the other party's sailing. ”

He casually pulled up a star map and circled an area.

"The starting area of the alien spacecraft, probably right here."

Looking at the empty target area, Dr. Mikoyan touched his beard thoughtfully: "Dark Star? ”

"You should know that in the long evolutionary history of the universe, in addition to a large number of planetary systems, there are actually a few dark stars hidden in those seemingly empty interstellar spaces." Old man Ivan explained calmly.

The so-called dark stars are wandering planets that wander outside the planetary system.

These wandering planets are asteroids, planets, ultra-faint red dwarfs.

Asteroids and planets, in particular, are difficult to detect by astronomical telescopes because they do not emit light.

Dark stars can also be called ghost planets.

Ivan guessed that the home star of the alien spacecraft is most likely a dark star, and it is still unknown whether it is an ultra-dark red dwarf star or a planet.

"Mikoyan, I want to mobilize a part of the cosmic astronomical telescopes to focus on this area and see if I can find this dark star."

Mikoyan thought for a moment: "This kind of planet should be difficult to lock, right?" ”

"It's hard, but I want to give it a try."

Seeing the gaze of his old friend, Mikoyan knew that this guy had made up his mind, and he nodded: "Okay! I can give you a letter of assistance to get those telescopes to work with. ”

"Thank you."

"You're welcome."

In fact, the Office of the Space Observatory has quite a few astronomical telescopes.

However, the astronomical telescopes in their office are on the Earth's ground and in low-Earth orbit.

In addition to the Space Observatory Office, there are five other institutions within Homo sapiens that also have astronomical telescopes.

These five institutions are: Space Division - Space Security Office, Science Division - Institute of Astrophysics, Ministry of Industry - Star Precision Instrument Group, Planetary Physics Equipment Group, and Hengguang Precision Instrument Group.

Among them, the astronomical telescopes of the Office of Space Security are the largest, densely covered with gold, wood, water, fire, earth and the six planets of the earth, with a total of 729 cosmic astronomical telescopes.

The Institute of Astrophysics has a total of 76 astronomical telescopes and scientific exploration equipment, which is almost the same number as the Space Observation Office.

Finally, there are starry sky precision instruments, planetary physical equipment, and constant light precision instruments, these three are equipment R&D and manufacturing companies, and they have 20~50 pieces of equipment operating in outer space, mainly for testing equipment.

The first institution Ivan contacted was the Institute of Astrophysics.

The two sides hit it off and quickly organized various types of astronomical telescopes to closely monitor that piece of the void.

And as time goes by, the Cicada-class 004 spacecraft has collected more and more information on the alien spacecraft.

This information further determines the power of the alien spacecraft, which is conducive to determining the speed limit of the alien spacecraft.

And the speed of the alien spacecraft is determined, and the departure time of the alien spacecraft can be added to determine the approximate location of its starting point.

In the end, Ivan and others finally locked on an approximate position, at a distance of 3.021~3.025 light years.

The angles and spatial coordinates, as well as the possible movement area of the ghost planet, have also been analyzed by other researchers.

According to this data, they gathered a large number of high-precision astronomical telescopes and detection equipment, and after four months, they finally found the clues of this ghost planet.

It is a gas planet with a radius 1.6 times larger than Jupiter, and a huge ring.

This planet can be found, thanks to the planet's huge rings, which increase the reflection area of starlight.

The planet is currently drifting in the other direction, and at its current rate, it is expected to reach the vicinity of Vega in 87.2 million years.

Apparently the planet is moving away from the solar system.

Although they don't know if the civilization on this planet is still there, after synthesizing various information, they still have some speculations.

Resource depletion and civil war are the two likely to be the greatest.

After all, this is only a large gas planet, and even if the gas planet abducts dozens of natural satellites, it is estimated that it is not enough for a civilization to develop to a level 1 civilization.

Extraterrestrial civilizations have discovered that their parent planet is drifting in the direction of distant Vega, and it will take another 87.2 million years to reach the vicinity of Vega.

It's a desperate time.

Even Ivan and others mourn for this civilization.

In the case of the continuous population growth of the home planet, unless their entire civilization can reasonably control the population growth, or adjust various technological developments, the resources will be depleted sooner or later.

Ivan and others speculated that the civilization might have been faced with two choices at the time.

One is to endure hard, and after 87.2 million, the mother star arrives near Vega, and then quickly immigrates to Vega.

Another option is to migrate to the nearest planetary system, the solar system.

However, according to the technological retrogression of alien spacecraft, the technological level of alien civilizations is half as good as that of current human civilization, and even some of the technology is not as good as Homo sapiens.

With such a level of technology, it is difficult to build a generation spaceship that tries to cross a distance of 3 light years and immigrate to the solar system.

Moreover, the major think tank offices of Homo sapiens have simulated the social form of this alien civilization.

Combined with the currently known information, there is a high probability that the alien civilization is not monolithic, but some members tend to wait conservatives, and the other part is radicals who tend to immigrate to the solar system.

This can be analyzed backwards from the fact that the other party only launched one generation spacecraft.

If this civilization is really united, then if they want to immigrate to the solar system, they will definitely not only have a generation of ships, but will concentrate all the resources of the home planet.

In this way, they can build at least a few hundred generation ships.

If there are really hundreds of generation ships, then this alien ship will not be completely extinct now, and the resources of large-scale generation ships can be scrapped by scrapping some spaceships, so as to ensure that some spaceships can be maintained.

It can be seen that in this alien civilization, the radical immigrants are very likely to be in the minority, and the vast majority of other aliens are conservatives.

Based on this conclusion, another piece of information can be deduced, that is, it is very likely that there are still surviving members on the home planet of the civilization.

This has forced Homo sapiens to be on high alert.

After all, the technology of this alien spaceship was only made by the civilization 45,200 years ago, and it does not represent the true technological level of the civilization now.

In case the other party's technology has advanced by leaps and bounds in the past tens of thousands of years, then this alien civilization will be a huge threat to human civilization.

After Li Qingye read these analysis reports, he immediately asked all departments of the company to discuss and make a plan to deal with the invasion of alien civilizations into the solar system.

And the other side.

The exploration of the alien spacecraft of the Cicada-class 004 spacecraft has also begun to enter a new phase, and they are ready to check the situation of the aliens.
