While people are celebrating their New Year and arguing over population policy, a series of subtle changes have taken place on the living planet next door.

There are three artificial satellites of humanity floating on this planet, monitoring the surface conditions at all times. The reason why there are only three of them is because humans did not carry more artificial satellites when they set off from the earth. For such a long time, there has been no anomaly on the surface of these three artificial satellites, so that people have gradually relaxed their vigilance.

Gliese 581g, an unremarkable terrestrial planet. Because it is more massive than the Earth, it has a thicker atmosphere, mainly composed of nitrogen, carbon dioxide, water vapor, and small amounts of greenhouse gases such as hydrogen sulfide and methane.

Even if the light intensity of the central star is not high, the average surface temperature can still reach about minus 20 degrees Celsius due to the effect of the greenhouse effect.

The temperature of minus 20 degrees Celsius is quite comfortable for life. Even the north and south poles of the earth have life tenaciously existing, not to mention alien creatures that have completely adapted to the environment.

Of course, the average temperature doesn't tell you anything, because the temperature varies greatly from region to region of the planet......

It's incredible!

Due to being tidally locked by the stars, Gliese 581g will always have only one side facing the star, and the light-receiving side will be extremely hot under the light for many years, and even the sea water in the center is almost boiling.

But on the other side of the night, it was an eternal night, which was extremely cold, with temperatures of more than 100 degrees below zero, causing all the water to condense into thick ice, forming a permanent ice sheet several kilometers thick.

This scene of ice and fire has formed an astronomical spectacle that people talk about.

But the planet's landscape is more than that, according to the laws of thermodynamics, heat spontaneously shifts from the hot zone to the low zone. The huge temperature difference between the two heavens of ice and fire has caused the air convection phenomenon of the entire planet to be extremely violent.

The heat and the water vapor evaporated from the sea water spontaneously transfer from the warm side to the cold side, which creates a huge gale.

Water vapor condenses and forms rainfall. Due to the heavy freezing on the shady side and the higher terrain, most of the rain will return to the ocean. This creates a planet-wide water cycle.

Large-scale air convection around the world has made typhoons of magnitude 15 or 6 commonplace, and in some cases, these violent hurricanes can reach magnitude 18 or even 20!

In order to adapt to this windy environment, almost all animals on this planet have a good ability to dig holes with one hand. When the wind blows, if you don't hide in the hole, you lose your chance to survive.

Coupled with the fact that the planet has very low oxygen levels and does not produce much energy from anaerobic respiration, the vast majority of animals are very short and crawl on the ground, somewhat similar to reptiles on Earth.

Such a living creature will crawl out of the ground to forage for food only when needed.

All in all, the twilight line is still the best living area on the planet, where the temperature is right, the precipitation is abundant, and there is a certain amount of light, as long as you can avoid the huge typhoon, life can live here very well......

Of course, the chaotic hurricane has also caused a huge obstacle to the entire scientific research operation of mankind. With the current productivity of human beings, it is estimated that there will be no return if the members of the scientific expedition team are directly put down......

Send some drones or survey vehicles to conduct field investigations, and within a few days they will be blown away by a hurricane, and then hit the ground heavily and be scrapped.

For poor human beings, every scientific instrument is precious, and in the current situation where there is no way to produce it on a large scale, one will be less damaged. Therefore, until now, human beings still have not been able to clearly express the specific situation, and can only use satellites to watch and monitor from afar in the sky......

After all, life means opportunity, but also ...... Crisis!

On this day, the wind and the sun were beautiful, the sky was cloudless, and it was rare to see good weather. The eternal sun hangs in the west and never sets.

A guinea pig-like creature emerges from the surface, vigilantly observing its surroundings, sniffing east and west, and making sensitive movements to forage for food.

The yellow and purple dwarf plants, with short leaves and well-developed root systems, are called "Aruba" by the Gliese people. In ancient times, it used to be a food that did not taste very much, and it was a raw material for clothes......

The guinea pig approached an "Aruba" and looked up at the sky.

It's not just an ordinary creature, it's a mechanical rat!

Powerful electronic eyes began to observe satellites at a distance of 330,000 kilometers.

There's the Earth Age, a massive spaceship, and a lot of machinery moving back and forth on the planet's surface......

The robot rat recorded all the data.

Yes, there is indeed intelligent life in this galaxy!

Even, and the technological strength far exceeds human estimates.

But fortunately, as the historians of the new civilization ultimately predict, the vast majority of civilizations in the universe are mediocre. The Gliese civilization is also in the midst of an unprecedented and irreversible Great Recession......

"Sir, this is the astronomical material we have photographed, please take a look!"

A Greeze, who is only one meter long, is prostrate on the ground respectfully, which is their unique culture of etiquette.

Because of their body structure, these intelligent beings don't need stools or beds. Usually when resting, I habitually squat on the ground, and when I sleep, I curl up my whole body.

According to human aesthetics, they look a bit like pangolins, with yellow skin with patches of scales and two front paws, which are good at burrowing.

Of course, with the current state of technology, they no longer need to dig holes with their claws, and they usually have their nails trimmed in order to do complex work better.

The chief flicked through the astronomical reports with concern, photo after photograph, huge spaceship, and all sorts of transportation equipment on the surface. Not particularly clear, but adequate.

Everything shows that this foreign civilization is not a scientific expedition, but 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 3,000 years ago came from the solar system, more than 20 light-years away from us. ”

"They're emitting signals all the time...... But we didn't reply. ”

"It seems to be called...... Mankind! ”
