Chapter 221
Just as people are celebrating their New Year and arguing about population policy, the life planet next door has undergone a series of subtle changes.
There are three human artificial satellites floating on this planet, constantly monitoring the surface conditions. The reason there are only three triflings is because humans did not carry more artificial satellites when they set off from Earth. For such a long time, these three artificial satellites have not experienced any abnormality on the surface, so that people have gradually relaxed their vigilance.
Gliese 581g, an ordinary terrestrial planet. Because of its greater mass than Earth, it has a denser atmosphere, with nitrogen, carbon dioxide, water vapor, and a small amount of hydrogen sulfide, methane and other greenhouse gases as the main components.
Even if the central star's light intensity is not high, under the effect of the greenhouse effect, its average surface temperature can still reach minus 20 degrees Celsius.
The temperature of minus 20 degrees Celsius is quite comfortable for life. Even the north and south poles of Earth have life stubbornly, even more how alien creatures that have fully adapted to the environment.
Of course, the average temperature data can’t explain anything, because the temperature difference in various regions of this planet is very huge...
It's incredible!
Because of being locked in by the stellar tide, Gliese 581g will always have only one face moved towards the star. The light-receiving face is under the illumination of many months and the temperature is extremely hot, and even the most central sea water is almost boiling.
But the other side is the eternal night, it is extremely cold, the temperature of more than one hundred degrees below zero, causing all the water to condense into thick ice, forming permanent ice with a thickness of several kilometers. Cover.
This scene of Fire and Ice Two Layer Heaven forms a astronomical spectacle that people talk about.
The landscape of this planet is more than that. According to the law of thermodynamics, heat will automatically transfer from the high temperature area to the low temperature area. The huge temperature difference between Fire and Ice Two Layer Heaven causes the air convection phenomenon of the entire planet to be extremely violent.
The heat and water vapor from the seawater transfer spontaneously from the warm side to the cold side, which creates a huge gust of wind.
Water vapor will condense and form rain. Due to the large amount of ice on the shady surface and the higher terrain, most of the rainwater will return to the ocean. In this way, the water cycle of the entire planet is formed.
Global large-scale air convection has made 15 Level 6 typhoons commonplace. Sometimes, these violent hurricanes can reach Level 18 or even Level 10!
In order to adapt to this windy environment, almost all animals in this planet have a good ability to dig holes with one hand. If you don’t hide in a cave when there is a strong wind, you will lose your chance of survival.
In addition, the oxygen content of this planet is very low, and the energy produced by anaerobic respiration is not much. Overwhelming majority animals are very short and crawl on the ground, a bit similar to the reptiles on Earth.
With such a lifeform, it will climb out of the ground to find food only when it is needed.
In short, the dusk line is still the best living area for this planet. Here, the temperature is suitable, the precipitation is abundant, and there is a certain amount of sunlight. As long as you can avoid the huge typhoon, life can live here very much. Ok...
Of course, the chaotic hurricane has also caused a huge obstacle to the entire scientific research operation of mankind. Based on the current productivity of human beings, if the scientific expedition team is put down directly, it is estimated that they will directly won but never returned......
Send some drones or survey vehicles to conduct field investigations, and they will be hurricane within a few days. Blow off, then smashed heavily on the ground and scrapped.
For poor human beings, every scientific instrument is precious. In the current situation where there is no way to mass-produce it, if one is damaged, one will be lost. So, up to now, human beings still don’t know the specific situation on the surface, and can only use satellites to watch from a distance in the sky and monitor...
After all, life means opportunity and also means With... crisis!
This day, bright sun and a gentle breeze, cloudless, rarely seen good weather. The eternal sun hangs to the west and will never set.
A lifeform like a guinea pig drilled out of the ground. It watched all around vigilantly, sniffing from the east and the west, and making foraging movements sensitively.
Those yellow and purple dwarf plants, with short leaves and extremely developed root systems, are called "Aruba" by the Gliese people. In Ancient Times, it used to be a kind of food with little taste, but also a raw material for clothes...
This guinea pig approached an "Aruba" and then looked up at the sky.
It is not an ordinary creature, but a mechanical mouse!
The powerful electronic eye began to observe satellites as far away as 330,000 kilometers away.
There is an Earth Era docked there, a huge spaceship, and a large number of machinery is moving back and forth on the surface of the planet...
The mechanical mouse recorded all the data.
Yes, this galaxy does have intelligent life!
Even, the technological strength far exceeds human estimates.
But fortunately, just like the ultimate prediction of the new civilization history, the overwhelming majority civilization in the universe is mediocre. Gliese civilization is also in the midst of an unprecedented and irreversible recession...
"Sir, this is the astronomical data we photographed. Please have a look!"
A Gliese person who is only one meter in length is crawling on the ground respectfully. This is their unique and respectful etiquette culture.
Because of the structure of the body, these intelligent creatures do not need a stool or a bed. I habitually squat on the ground when I rest, and curl up my whole body when I sleep.
According to human aesthetics, they look a bit like Pangolin. Yellow skin is covered with scales, and the two front paws are flexible and powerful. At first glance, they are a species that is good at digging holes.
Of course, as far as the current level of technology is concerned, they no longer need to dig holes with their claws. In order to better perform complex tasks, they usually trim off their nails.
The chief looked anxiously through the astronomical report, one after another, the huge spaceship, and the various transportation equipment that appeared on the surface. Not very clear, but it's enough.
Everything, everything shows that this foreign civilization is not a scientific study, but is to take root here!
Several other Gliese people are gathering in this small room underground to discuss: "According to our analysis, it is likely that the civilization that sent the signal more than 3000 years ago, the source In the solar system, more than 20 light-years away from us."
"They have been sending signals...but we have not responded."
"It seems to be called...human!"
