Zhao Dahe stood on the podium, took a deep breath, and looked at the expectant eyes on the scene, faintly feeling a heavy pressure.

Exploring the satellite system will carry the hope of the future of the Ocean Group and determine the future development direction, which must not be careless. This will make it possible to bet on the entire accumulation of the Dayang Group and the 'national fortunes' of the next 350 years, or even 100 years.

Although it is a bit strange for a group to say 'national fortune', it is almost what it means.

And now the heavy task of exploring the satellite system falls on Zhao Dahe.

Zhao Dahe slowly inserted the mobile hard drive into the computer on the podium, and then turned on the big screen. Moments later, a hovering galaxy appeared on a large screen with a total area of 150 square meters in the conference hall.

The galaxy has four spiral arms, but the ends of the spiral arms fork and begin to blur, eventually forming a fuzzy ring around the outer reaches of the galaxy.

On the outskirts of galaxies, there are also sparse nebulae and scattered small stars forming a 'dust circle', which is almost a quarter of the diameter of the main body of the galaxy and surrounds the entire galaxy like a protective ring.

If the galaxy is flattened, this dust circle is basically spherical, 'protecting' the entire galaxy.

Not far from the outer periphery of the galaxy, outside the 'dust circle', there are more than a dozen small galaxies or star clusters that are more significant, in addition to many scattered points of light.

In fact, there are quite a few star clusters in the 'dust circle', but they are too small.

Seeing this star map, everyone's eyes seem to be brighter.

Zhao Dahe spoke: "What you see now is the picture of the Zhou Tian Great Galaxy, which is the latest. Of course, although it is the latest, it is not entirely certain that our Zhou Tian galaxy is in this shape.

We are inside the Zhoutian Galaxy, and it is not easy to recognize the true shape of the Zhoutian Galaxy. So a lot of it is deduced by computers.

We also borrowed pictures taken from the Demon World, but because of the distance and the inability to arrange a large astronomical observation system in the Demon World, the pictures taken were blurry. And the pictures we took from the Heavenly Demon World are side pictures, not front pictures.

Later, after continuous correction, I got the current picture.

To put it bluntly, one-third of this area is directly generated by the computer, not the real image. The location on the back side of the galaxy's core has not been observed in detail so far.

Let me start with a brief overview of the Great Galaxy next week.

At present, the data we have detected is: the diameter of the Zhoutian Great Galaxy is about 16~200,000 light years, and the whole is flat.

If calculated according to the gravitational range of the Zhou Tian galaxy, the maximum range is 20 light-years in diameter. Beyond this range, the star will break away from gravity and drift in the stars.

Just as there is an escape layer in the planet's atmosphere, this is also the fugitive layer of a galaxy.

According to this calculation, the thickness of the Zhoutian galaxy is about 30,000 light-years.

The periphery of this fugitive layer is the 'dust circle' that you see. Here, satellite systems and large galaxies compete for each other's stars, interstellar dust, etc.

There is also a calculation method, which is calculated according to the maximum range of the spiral arm. The diameter is 160,000 light-years. By this calculation, the thickness of the galaxy is 7,000 light-years.

In addition, in the Zhou Tian Great Galaxy, the area shrouded by the 'Zhou Tian Great Array' should be 80,000 light years. The extent of Sanyuan, the core part of the Zhoutian Galaxy, is about 20,000 light-years away. Migaki doesn't look really big, only 6.3% of the total volume of the entire galaxy, but the mass is enough to be 40% of the entire galaxy!"

Zhang Hao asked, "What is the significance of the two calculation methods?"

"The first way of computation, in an academic sense, is conducive to our understanding of the universe. The second is of practical significance, and in practical application, it is good to calculate according to the second one. ”

Zhang Hao nodded.

Zhao Dahe continued: "Now let's talk about the focus of this discussion, the satellite system.

At present, we have found large and small satellite systems and star clusters around galaxies, a total of 12 of which are qualified to be recorded separately. We numbered them in the order in which they were found.

However, although qualified to be recorded and observed individually, not all satellite systems or clusters have the potential to develop into new bases for the Ocean Group. For example, we recently discovered Cluster 12, which can only be barely called a star cluster.

Cluster 12 is about 30 light-years long, but there are fewer than 400 stars, most of which are small stars, mainly red dwarfs. This star cluster doesn't even have a black hole of its own. In its center, it is only a red giant.

The stars are small and there aren't many planets. There is a serious shortage of basic supplies.

Therefore, after preliminary screening and rigorous discussion, the astronomical research department preliminarily selected three satellite systems, 1, 2, and 5. Today we will have a final discussion on the three satellite systems. Let me briefly introduce these three satellite systems. ”

"No. 1, we named it 'Pisces Nebula', and we use 'nebula' to distinguish it from large galaxies.

The Pisces Nebula is a complete small galaxy and the second largest moon system we have discovered. Our preliminary research suggests that it is a complete independent galaxy attracted by the Zhoutian Galaxy.

At present, the Pisces Nebula is falling towards the Great Galaxy at a speed of 117 kilometers per second. It is expected that after 1.2 billion years, it will be completely captured by the Zhoutian Galaxy and integrated into the Zhoutian Galaxy. Of course, we can ignore such a long time.

The Pisces Nebula has two spiral arms that look like Pisces playing with pearls, and its core, the 'beads' of 'Pisces playing with pearls', is a massive black hole, which is tentatively estimated to be 1.3 million times the star of Tianyuan.

The Pisces Nebula is about 7,600 light-years in diameter and has about 27 billion stars. It is about 155,000 light-years away from the core of the Great Galaxy of Zhoutian, and about 165,000 light-years away from us. Because of the interstellar movement, the distance between it and the Tianyuan Star is close to 22 kilometers per second.

The Pisces Nebula has the greatest potential for development. ”

"No. 2, we named it 'Oasis Nebula'. The Oasis Nebula is chaotic as a whole, the nebula is rich, and we even observe the star-making phenomenon in the nebula.

However, the Oasis Nebula has a very high density of stars, and the name 'Oasis Nebula' is also due to the high energy density and the overall green luster under the telescope. According to the energy level, it is much higher than the red and yellow levels.

The energy level is the rainbow colors of red, orange, yellow, green, blue, and purple, and we use this to mark the energy distribution of the universe.

We speculate that the Oasis Nebula should have swallowed half of the galaxy by the Great Galaxy, which devoured its periphery, leaving behind the inner core of the galaxy.

The Oasis Nebula is 3,700 light-years in diameter, but its core black hole is estimated to be 2.2 million times the mass of the Celestian Star. The number of stars in the Oasis Nebula is estimated at 15 billion. But because the nebula is relatively rich, it is not real.

Compared to the Pisces Nebula, it seems to have more potential for development. But it's a little further away from us.

The Oasis Nebula is about 170,000 light-years away from the core of the Zhoutian Galaxy, and 157,000 light-years away from us, and the distance from the Tianyuan Star is 27 kilometers per second due to interstellar motion.

The Oasis Nebula has a stable orbit and has formed a perfect balance with the Zhoutian Great Galaxy. ”

"Then there's the number 5, which we named 'Carp Nebula'. This satellite system is forward, equivalent to the position of the fish's head, and is a relatively standard vortex system, but there is no difference in the spiral arm.

But it dragged a long tail, like a comet. In fact, the Carp Nebula is being torn apart and swallowed by the Great Galaxy.

Of the three options, the Carp Nebula is the smallest, with a body diameter of only 2,400 light-years and an estimated number of stars around 5 billion. Its core black hole is estimated to be about 900,000 times the size of Tian Yuan Star.

The Carp Nebula is only 120,000 light-years away from the core of the Zhoutian Galaxy, and less than 80,000 light-years away from Tianyuan. It seems to be the easiest satellite system to reach.

Because of the interstellar movement, Tian Yuan is 'catching up' with the Carp Nebula, approaching 31 kilometers per second.

However, if you want to reach the Carp Nebula, you need to go through the constellation of the Celestial Society, which is the location of the Red River civilization and the military secession regime.

Based on the relationship between the Celestial Garden constellation and the gravitational string, we may need to borrow the gravitational chord of the Celestial Constellation. The Celestial Constellation is also an elongated constellation, and it should be easy to find the gravitational strings.

That's all for a brief introduction. If you have anything to ask, just ask. ”

After Zhao Dahe's introduction, everyone became lively. Bai Yutang was the first to speak: "I have a question, 12 satellite systems or star clusters have been discovered so far, can you briefly introduce the rest, why did you choose these three in the primary selection?"

I remember that there was a 'satellite system 4', named 'Straw Hat Nebula', which seemed to be more than 12,000 light-years in diameter, and it was the largest satellite system ever discovered. Why isn't it included in the selection?"

Zhao Dahe smiled and pointed to the star map on the display screen behind him, "The Straw Hat Nebula is here, located on the back of the galaxy, 190,000 light-years away from the core of the Zhoutian Great Galaxy, but 260,000 light-years away from us, and the center needs to be crossed over the Zhoutian Great Galaxy core." It's unrealistic to reach the Straw Hat Nebula.

Besides, the Pisces Nebula is big enough.

The rest of the satellite systems or clusters have similar problems, either because the clusters are too small or too far away. ”

Saying that, Zhao Dahe introduced the rest of the satellite systems and star clusters one by one, most of which were like the No. 12 star cluster, and the researchers didn't bother to take the name from, just give a number.

After the explanation, everyone has to agree that the three satellite systems 1, 2, and 5 are the most potential among them.

But which one is exactly what it is, we have to discuss it carefully.

There is one thing that the top management of the Ocean Group understands very well: with the current technical situation and background of the Ocean Group, it can only organize a fleet and explore a galaxy. It will take 30 years at the earliest. With a slight delay, it's fifty years. Again, taking into account the velocity of the gravitational strings.

Such a fleet should have the ability to develop and build a galaxy, rather than simply three or five spaceships going around in a circle. According to preliminary estimates, at least 3,000 spacecraft will have to be sent.

But now that the Blue Star Group is facing a big war, all kinds of resources are beginning to be strained, and in another thirty or fifty years, a war may break out at the gate of the world in the rear, and it will be a war between the two worlds.

Therefore, if you think about it casually, you can understand that the opportunity for the Ocean Group to explore the satellite system will only have one chance in the foreseeable century!

If you don't succeed the first time, it will be difficult to follow. In particular, it is unknown whether the rest of the members of the Blue Star Group will have other thoughts.

Moreover, judging from the current development speed of Dayang Group, in another 30 years, the development space of Dayang Group will reach the limit. The Ocean Group desperately needs a piece of territory that is completely its own!

The entire Dayang Group is under tremendous pressure, but even if the pressure doubles, it still has to move forward with a heavy load. The huge pressure of survival makes Dayang Group not only unable to slow down, but also to continue to accelerate.

If you want to relieve the pressure within the group, you have to take another approach. For example, marriage, through marriage to rejoice. Or explore outer space to give vent to the pressures within the group.

In short, it is under this premise that the senior management of the Ocean Group has discussed the three satellite systems at present. Gradually, however, the discussion focused on the 1 and 2 satellite systems. It's just that in this process, Bai Yutang never spoke.

The Pisces Nebula, the 1 satellite system, appears to be the most promising, but it's a bit far away, 165,000 light-years from Tianyuan.

The No. 2 satellite system, that is, the Oasis Nebula, has a lot of potential, and the distance from the Tian Yuan Star is 157,000 light years, but the distance between this galaxy and the Tian Yuan Star is being widened, 27 kilometers per second, then it can be opened 8.5~860 million kilometers a year.

This distance...... Maybe negligible. Today's spacecraft are often thousands of light-years per month, and hundreds of millions of kilometers are drizzling. Even at 860 million kilometers per year, it would take about 11,000 years to pull a light year apart.

It's just that choosing the Oasis Nebula isn't that easy. Because the Oasis Nebula has a thick nebula inside!

Imagine how a planet's industrial development and life would be affected if it was covered in fog all year round. And that's what happens with the Oasis Nebula.

In addition, according to astronomical telescope observations, through occultation observations, it is suspected that there are a large number of super-large starry sky monsters in the Oasis Nebula.

For this, Zhao Dahe emphatically explained: "The so-called occultation observation is very simple. If a person walks in front of a light, it will obscure the light, causing the light to be dim. Similarly, if a planet passes in front of a star, it will also obscure part of the star's light, causing a slight change in the star's light.

This change may be 1 in 10,000 or 1 in 100,000, but with the high-precision telescope matrix we can find a faint change 100,000 light-years away.

The Oasis Nebula is a bit far away, but after technical adjustments, it can barely observe some occultations of periphery, blue giants. But we found that the stars here change quickly and irregularly. Whether it's the frequency, or the intensity of the occlusion.

At first we thought it was a spaceship. But it was quickly ruled out. Because the route of the spacecraft is generally relatively stable.

Everyone should know that the spaceship is fast in the starry sky, and the route of the spacecraft is fixed for safety. Even those small countries in the Great World of Zhou Tian will have such an arrangement.

Finally, after comprehensive consideration, referring to the opinions of the General Staff, we believe that it is a starry sky monster. Moreover, in the entire Oasis Nebula, there are only a few such starry sky monsters. These starry sky beasts that have been developing freely for an unknown number of years may not be what we can deal with now.

After all, we speculated that the Oasis Nebula was most likely the remaining core of a large galaxy. The original size of this large galaxy is estimated to be one-quarter to one-third the size of the current Zhoutian large galaxy. It is completely understandable that such a place gave birth to a starry sky monster. ”

Zhang Hao listened to it and couldn't help asking: "How long has this situation been observed, and how sure is it?"

"We have been observing this phenomenon for half a year, and we have called on almost all telescopes to form a superarray to observe.

This superarray of telescopes has formed a virtual super-telescope with a diameter of 120,000 kilometers, and the observation accuracy is ...... It should be above ninety. ”

The virtual telescope is a telescope technology of the Ocean Group. By arranging a large number of telescopes into an array, all the telescopes are linked together by a computer to form a bee-eye-like structure. It's just that this bee's eye is a bit big, and it can reach 120,000 kilometers.

Through such technology, the current telescope technology of the Ocean Group can be brought into full play, and the sensitivity of a single telescope can be exerted one million times. Of course, costs are also rising.

But through such telescope technology, the Ocean Group has also benefited a lot.

Zhang Hao groaned slightly. From the current point of view, the Oasis Nebula is undoubtedly the most suitable. But if there really are a lot of starry sky beasts here, it's a different story.

After pondering for a while, Zhang Hao suddenly said, "Is it possible to do this?" We could send a fleet to the Pisces Nebula, but turn a corner in the middle and pass by the Oasis Nebula. ”

"I'm afraid this won't work. There is a great distance between the two nebulae. ”

Zhang Hao said again: "Then what if you just try to get as close as possible to the Oasis Nebula and observe it up close?"

Zhao Dahe pondered for a while, looked at the star map, and said, "If you want not to affect the trip to the Pisces Nebula, it is at most close to 50,000 light years. Then you'll have to turn around and head to the Pisces Nebula.

But if we could move forward 50,000 light-years, we might be able to double the clarity of our observations. ”

But at this time, Bai Yutang, who had been silent, spoke, "I think it might be better to explore the Carp Nebula." ”

"Oh?" everyone focused their eyes on Bai Yutang.

But seeing Bai Yutang stand up, walked to the podium, and walked to the front of the star map, he swiped his finger across the Tianshe constellation, "Everyone, the Tianshe constellation is basically independent for the time being, and it is no longer controlled by the royal family of the Red River Empire, nor is it controlled by the Yujing Empire. There is even intelligence that the Celestial Society constellation is colluding with the 'Celestial Empire'.

The Celestial Empire is located in the east of the Yujing Empire, and this kind of interstellar power has been facing each other for tens of thousands of years.

But now that the Blue Star Group is facing a big war, the Yujing Empire is afraid that it will not be able to take care of it here. Then we may have the opportunity to buy the Celestial Constellation from the Yujing Empire, and also buy the Celestial Constellation from the Royal Family of the Red River Empire.

The Celestial Constellation is almost located on the edge of the Zhou Tian Great Galaxy and the Zhou Tian Great Array, and it has little meaning to the Yujing Empire. The Red River Empire is also beyond its reach. So I think that both the Yujing Empire and the Honghe Empire will agree.

The Celestial Constellation is only a military secession regime of the Red River civilization, but such a secession is not popular with the people. Moreover, the development time of the constellation of the Celestial Society is short. There is very little underwriting. Once we have nominal ownership, we can take this place strongly!"

"One more important thing is that. Saying that, Bai Yutang's fingers crossed the constellation of the Heavenly Society, "The constellation of the Heavenly Society is slender, everyone looks like a guide rail, a guide rail of gravitational strings." If we can include the Celestial Snake Constellation in our sphere of influence, we will be able to use the gravitational strings of the Celestial Constellation to 'launch' the fleet and reach the Carp Nebula faster.

As for the problem that the carp nebula is small, I don't have to worry about it at all in the short term. This is enough to support the recent demand of the Ocean Group. ”

Bai Yutang's suggestion aroused everyone's great interest in an instant. Yes, the Ocean Group and the Tian Yuan Star Civilization have now grown into overlords, and they no longer need to be as cautious as in the past.

Previously, Gao Gao Shang also obtained the small star cluster of 'Jinghui 16 Stars' from the royal family and completed the occupation. Then now it seems that it is nothing to get involved in the constellation of the Heavenly Society.

Another important point, which has actually been discussed before, is the fuel of the spaceship. At present, the nuclear fuel of the spacecraft can travel up to 10,000 light-years at a time. If you want to cross the 100,000 light-years starry sky, even if you add storage space technology, you have to refuel at least twice in between.

If you want to go to the satellite system, you have to think about the supply station. Therefore, the significance of the constellation of the Celestial Society has invisibly added another layer.
