Long before Voyager arrived in this star system, probes to explore the entire galaxy had already been dispatched. It's just that because www.biquge.info of the anxious disaster on the Voyager in the early days, not only Zhou Xin's attention, but even the focus of the probe's exploration is all on the planet where the base is being built, and the attention to other places in the galaxy is far less than that planet. However, after all, a small number of probes were sent to the entire galaxy, so when Zhou Xin suddenly asked Atlas about the situation of the star system they were in, the little girl was not ignorant.

"There are three stars in this galaxy that can be called planets. Among them, the planet closest to the star and also the captain's brother is an ordinary rocky planet. The situation on this planet has been carried out in great detail in previous investigations, so it will not be explained in detail. At the beginning, Atlas first gave a brief introduction to the information that Zhou Xin already knew. Then, she continued, "In addition to this, there is a rocky supergiant planet at a distance of about one astronomical unit from the star. It's not as exaggerated as the supergiant planet we've encountered before, about five times the diameter of the Earth, but it's quite exaggerated among rocky planets. As she spoke, the little girl showed a picture of the supergiant planet on the screen.

It was a slightly grayish-yellow planet overall, and due to the shooting distance, there was not much detail on the planet's surface in this image on the screen. But even so, in addition to the streaks all over the surface of that planet, Zhou Xin still saw something of interest.

"There's an atmosphere on the planet's surface?" Looking at the irregular pale red objects that appeared on the surface of the planet in the picture, Zhou Xin asked curiously.

"Brother Captain, you're right, the surface of this planet is indeed covered with an extremely thick atmosphere." Atlas nodded and replied, "However, according to the findings sent back by the probes who arrived on the planet. The planet's atmosphere is mainly composed of toxic gases composed of nitrogen oxides, in addition to small amounts of carbon dioxide and water vapor. Brother Captain, you saw the floating clouds in the picture, which were actually strong acid clouds formed by the combination of nitrogen oxides and water vapor. Of course, that's all you can see in the picture. In addition, most of the planet's surface is still blowing strong winds of more than 12 all year round. The first probe to land on the surface of that planet was completely destroyed by the strong winds on the planet. ”

Hearing the content of Atlas's report, Zhou Xin, who had originally raised a little interest, immediately felt a little disappointed, "In this environment, it seems that there is no life on this planet." ”

Nodding, Atlas agreed with Zhou Xin's opinion, "Indeed, the possibility of a life similar to the captain's brother on the planet is too low. ”

"Forget it, luck can't always be on our side every time, there is no life without life." During the whole journey, Zhou Xin can be regarded as having seen a lot of lifeless planets. So he was just disappointed and returned to normal, and then comforted himself: "At least one of our crises has been solved here." With that, he motioned for Atlas to continue with the supergiant planet's information.

"Because the environment on that planet is too harsh, until now, people have tried four or five times, but they have not been able to get the probe to land on the surface of the planet. Those probes were either destroyed by the strong winds on the planet, or they were not protected from the corrosion of the strong acid environment for a long time. The most infuriating thing is that yesterday there was a probe that was about to land successfully, but the probe did not fully understand the nature of the atmosphere on that planet, and just as it was about to approach the ground, the probe actually flew again under the impetus of the device originally used to slow down. By the time they reacted, the detector had already been destroyed by the strong winds in the air. Speaking of this, even the little girl was a little angry, "Hmph, today people are going to personally control a probe to land on that planet." People don't believe it, and with other people's personal departures, this landing will not be successful. ”

Hearing Atlas's unconvincing words, Zhou Xin couldn't laugh or cry, but then he was also a little surprised and curious about the little girl's description. Then, a series of questions came out of his mouth, "Did the probe fly again while performing the landing procedure?" We've never been in this situation before, so aren't we sure the probe itself is having a problem with the landing procedure? Also, you just mentioned that the probe doesn't know about the planet's atmosphere, is there anything special about that planet's atmosphere? ”

"There must be nothing wrong with the probe, because there was still normal communication with the probe when it landed." Atlas replied, "And, based on the data sent back before the probe crashed, the cause of this anomaly has been analyzed." After a pause, the little girl explained, "Brother Captain, you can't imagine how much air pressure there is near the surface of that supergiant planet. After selling it a little, a value came out of her mouth that surprised Zhou Xin extremely much, "It has reached three hundred times the standard atmospheric pressure of the earth!" ”

"Three hundredfold?!"

"Brother Captain, you heard it right, it's three hundred times." Atlas nodded in confirmation, "Such a dense atmosphere would have had a good cushioning effect. Even if the thrust reverser is not turned on, the speed of the probe will be long gone by the time it approaches the planet's surface. However, the intelligent program on the probe rigidly turned on the thrust reverser according to the landing process, and it was still at full power, which broke down, causing the probe, which was originally very slow to land, to fly again. By the time people received the abnormal information from the detector, it had been in reverse for a long time, and it was already too late for people to pass on the adjustment instructions at this time. After explaining, he comforted Zhou Xin, "But it doesn't matter, since we already know the situation on the surface of the planet, there will be no problem with the operation of the next probe." As long as people find a way to avoid the strong winds and acid rain clouds high above the planet, they should be able to reach the ground without any problems. ”

"In that case, there is no problem, just continue to send probes to the surface of the supergiants." Knowing that the problem was not with the detector, Zhou Xin's mood suddenly returned to normal. For him, losing a few probes in the process of exploration is not a problem at all, but it is even more important if there are any operational problems with the probes themselves.

Because the probe has not yet begun to explore the surface of the supergiant planet, it has only captured some footage from space and sent back a small amount of data before it crashed in the atmosphere. So after a brief introduction, Atlas can't provide more information about supergiant planets for the time being. After telling Zhou Xin that he would continue to explore the planet's surface in the future, Atlas turned the conversation to another planet in the star system.

"The outermost planet is actually an ordinary gas giant." As he spoke, Atlas switched the screen, revealing a blue-green planet on the screen. While Zhou Xin carefully observed the planet, the little girl continued, "The distance between this planet and the central star is about thirteen astronomical units, about three-quarters the size of Jupiter, but it is not exactly the same as Jupiter. According to the data sent back by the probe, although the surface of the planet is rich in hydrogen and helium, which are the two elements of gas giants, there is also a large amount of methane, water and other substances present in ice giants. Therefore, although the planet mainly exhibits the properties of gas giants, it is mixed with the properties of some ice giants, the most obvious of which is also the color of the planet's surface. Of course, there are other interesting things about this hybrid nature on this planet, many of which are new information that has never been recorded before, and can almost be considered a new type of planet when you think about it. ”

"As for why the planet is the way it is, analyze it based on the information available now. It has been speculated that the planet is now in an orbit just halfway between the orbit of a pure gas giant and the orbit of a pure ice giant. So in the early days of the planet's formation, it gathered the material that originally belonged to two different planets, and then it became what we see now. After saying this, the little girl's tone became strange, "Based on the results of many simulations of the formation of star systems. Theoretically, this type of planet can indeed form naturally in the universe, but the probability is too low, and we didn't expect to be lucky enough to meet one of them. And generally speaking, even if such planets exist, methane and water should sink into the interior of the planet, rather than mixing with light elements such as hydrogen and helium, as we see now. This proves that the planet should be a young planet that has only been born for a short time, and its surface is not active enough to stratify the different components of the planet. ”

Atlas's explanation Zhou Xin understood, but after understanding, his brows furrowed, and at the same time, he said to himself thoughtfully: "Isn't it a pure gas giant?" In that case, doesn't that mean there will be an impact on our fuel harvesting? ”

"There will be some impact, but it won't be huge." Atlas replied, "When we gather resources on ordinary gas giants, we also need to separate the impurities in them, but now we need to separate more impurities and the composition is more complex." The existing equipment on board the ship is sufficient for the job, but it may not be as efficient as it would be when it were a pure gas giant gathering resources. ”

"That's good." After listening to the little girl's explanation, Zhou Xin breathed a sigh of relief, and then motioned for her to continue the introduction.

"The investigation of the ice-gas giant is still ongoing, and many strange phenomena still need to be observed for a long time before an accurate conclusion can be drawn." Atlas said, "There are a lot of things that people are not sure about now, so let's tell the captain's brother after a while when they have investigated clearly." ”

"That's fine." Zhou Xin nodded, and then he commanded, "Since it is a new planet type, it is a big discovery. Let the probe collect more information on the planet and try to deepen our understanding of that planet. For that reason, it doesn't matter if we stay here any longer. ”

"People get it." The little girl agreed, and then she mentioned another discovery of the probe in this star system, "Brother Captain, in this star system, in addition to the three planets we know, the probe has also found two asteroid belts. ”

"Two?" For Zhou Xin, the discovery of the asteroid belt was not such a surprise news, but he was interested in the number of asteroid belts mentioned by Atlas.

"It's two, and they're between the first and second planets and the second and third planets in this star system." "The asteroid belt between the first and second planets is quite narrow, and the number of asteroids is not large, probably no more than 10,000," Atlas elaborated. But the asteroid belt on the periphery is different, it's extremely wide. It spreads from about three AU to 10 AU from the star. According to estimates, the number of asteroids may be in the hundreds of millions. ”

"How is that possible?" Zhou Xin said with some disbelief, "How can there be such a large asteroid belt, it stands to reason that they should be able to gather together to form a larger planet." ”

"The probe did observe anomalous clustering at a few locations within the asteroid belt," Atlas said, "but it's estimated that it will be a long time before a mature planet finally emerges." She then went on to add, "In addition, in addition to the anomalous aggregation points, the two massive planets on either side of the asteroid belt orbit are also relying on their strong gravitational pull to constantly pull the asteroid out. Many of these asteroids flew out of the star system after a drastic change in their orbits, but some of them were also captured by the gravitational pull of the planets and became moons of the two planets. As a result, the probe observed the presence of a large number of moons around the other two planets, possibly in the triple digits for each. ”

This news did not attract Zhou Xin's special attention, after all, it was not unseen before on a planet with many moons. After talking about the asteroid belt, Atlas went on to describe the probe's other discoveries in this star system. However, compared to the previous discoveries, the little girl is going to introduce the general phenomena that can be seen in most other star systems, and there is nothing worth mentioning.

After listening to Atlas's introduction for nearly a day, Zhou Xin finally got a preliminary understanding of the star system he is in now......
