Voyage of the Stars.

Chapter 895 Sulfur-based Organisms
The exploration team of the Red Flame Civilization of the Star Alliance had very good execution capabilities. After receiving instructions from the Lyra, they immediately conducted a more detailed exploration scan of the rogue planet.

However, it is not a reconnaissance spacecraft that lands in person, but some smaller probes are dispatched. This is mainly for concealment considerations. After all, the smallest reconnaissance spacecraft is mountain-sized, which is still too large for landing on a planet and may cause a lot of noise.

There would be no problem if covert detection was not required, but before finding out the specific situation, the people on the Tianqin obviously did not want to be too conspicuous.

It is a good time to send out detectors for scanning and detection.

The Chiyan people were quite efficient and before long, the Tianqin received a steady stream of the latest detection information.

Xian Donggui at the command center was inputting information into the model while introducing it to Yue Yuan.

"Captain, this is the latest scan data. It seems that our previous guess was correct. A certain civilization used their planet as a spaceship to travel out of the interstellar space. Their destination is this yellow dwarf star. Based on their trajectory, their departure point should be here."

Following Xian Donggui's words, a star map appeared on the holographic screen, showing three planets, namely a yellow dwarf star, a wandering planet, and a yellow dwarf star. In other words, this wandering planet was going from the yellow dwarf star at the other end of the starry sky to the yellow dwarf star at the other end.

They were still about four light years away from their destination. At their current speed, it would take at least eight hundred years. It was true that this wandering planet had reached 1% of the speed of light relative to the target star, but it was impossible for it to reach its destination at this speed and then decelerate from 1% of the speed of light to a standstill in an instant. They would definitely need hundreds of years of deceleration.

As for the star they set out from, humans had not paid much attention to it before, but after some exploration of it, they discovered that it was a yellow dwarf star that was about to evolve to the next stage. It had a lifespan of about 10 billion years, and its hydrogen fuel was almost burned out.

The mass of this planet is much larger than that of the sun, so its life span is much shorter, only 10 billion years. That civilization must have known the situation of the stars in their home galaxy, so they drove away from their home planet.

Judging from the detection situation, there is definitely life on this wandering planet, but not on the surface of the planet. At least for now, humans can only see 30,000 planetary engines as big as mountains and the ruins of buildings on the surface of the planet.

Judging from the buildings on the surface of the planet, the civilization on this planet was once prosperous. However, their architectural style is rather peculiar. They are not high-rise buildings like humans, but mushroom-shaped buildings. Although they are damaged everywhere, with the help of human information restoration technology, they can be repaired to their original appearance.

If you look down from space, the buildings on the ground are probably not much different from looking down at a mushroom colony.

After seeing this group of dilapidated buildings that looked like mushrooms, and then looking back at the planetary engines, Yue Yuan discovered that the architectural style of these planetary engines was very similar to an upside-down mushroom.

From the scanning images, we can see that there are traces of roads on the land of this planet, and information on the planet's atmospheric composition was soon transmitted back by the probe.

Yes, it still has an atmosphere, but its density is much lower than that of the Earth's atmosphere. It should be that the planetary engine blew away a lot of the atmosphere when pushing the planet.

There is about 10% hydrogen sulfide in the atmosphere, the majority is nitrogen, and the rest is a small amount of carbon dioxide, carbon monoxide and other gases. Oxygen accounts for a very small proportion here, which is no different from rare gases.

It's amazing that it is a planet with almost no oxygen.

There is water on the planet, but because the planet was ejected from orbit, the water has now frozen into a vast ice sheet. The probe also analyzed its composition and found that its water contains hydrosulfuric acid. Obviously, the water on this planet must be a mixture of water and hydrosulfuric acid when it is not frozen.

Apparently that's because the hydrogen sulfide in the atmosphere is dissolved in water.

This kind of water obviously has the characteristics of hydrosulfuric acid, which is corrosive and toxic, and smells like rotten eggs to humans. The hydrogen sulfide gas in the atmosphere is full of the smell of dry toilets, which is like a planet immersed in a toilet in the 1980s and 1990s.

It seems that this is the environment in which the creatures on this planet live.

The surface of the planet has been completely changed, but many frozen plants can still be seen. They are purple in appearance. The probe has already fished out some of these plants for analysis by the research department.

The results showed that these plants also have the ability to absorb stellar light energy by extracting hydrogen from hydrogen sulfide and then giving the hydrogen to sulfur dioxide to create sulfide.

After a series of tests, the biologists were very excited because they concluded that this was a sulfur-based plant and sulfur-based life. After reaching this conclusion, they also asserted that the unknown civilization hidden underground on this planet must also be sulfur-based and be a sulfur-based life form.

Humans have been in the starry sky for so long and have encountered many strange life forms, but except for some special life forms, such as Adélie, they are basically carbon-based life forms. Unexpectedly, they have encountered sulfur-based life forms now.

How could biologists not be happy? It was a life form that had never been seen before.

Human research in the field of life sciences has been stagnant for a long time. Perhaps this form of life can inspire humans.

As the exploration deepened, humans also discovered many places that were obvious entrances to the basements, but basically the doors were tightly closed and there were not even any lights. The entire planet seemed quiet, like a world that had been dead for a long time.

However, humans know that this world is not dead, it is just temporarily dormant, only on the surface. Because through detection methods such as neutrinos, humans can roughly scan these underground bases.

Through detection and scanning, humans have discovered that there are approximately 60,000 huge underground bases on this planet, which should be the habitats of the indigenous people of this planet. However, this type of scanning technology can only give a rough idea of ​​what the indigenous people look like. We can only know what they look like after entering them or waiting for them to open the door and come out.

We can’t see it for the time being, so humans are not in a hurry.

Because in the process of the detector scanning the planet with neutrinos, humans also discovered another interesting phenomenon, that this planet actually has a cooled core.

In other words, it no longer has geological movements and does not have a hot core like the Earth, so there are no plate movements, earthquakes, and naturally no geothermal energy.

Generally speaking, this situation often occurs on planets far away from the main sequence stars, but I didn’t expect this planet to be like this.
