Chapter 215

Just as people are celebrating their new year and arguing about population policy, a series of subtle changes have taken place on the life planet next door.

There are three human satellites floating on this planet, monitoring the surface conditions all the time. The reason why there are only three satellites is that human beings did not carry more satellites when they set out from the earth. For such a long time, the three satellites have not had any surface anomalies, so that people have gradually relaxed their vigilance.

Glitzer 581g, an ordinary earth like planet. Because of its larger mass than the earth, it has a thicker 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 light intensity of the central star is not high, under the effect of the greenhouse effect, the average surface temperature can still reach about minus 20 degrees Celsius.

The temperature of minus 20 ℃ is quite comfortable for life. Even the earth's north and south poles are tenacious existence of life, not to mention has been fully adapted to the environment of alien creatures.

Of course, the average temperature doesn't mean much, because the temperature difference between different parts of the planet is very huge

It's incredible!

Because it is locked by the tide of stars, Gliese 581g always has only one side facing the star. Under the light for many years, the temperature is extremely hot, and even the most central water is almost boiling.

On the other side, however, it is an eternal night. It is extremely cold. The temperature of more than 100 degrees below zero causes all the water to condense into thick ice, forming a permanent ice sheet several kilometers thick.

This double sky scene of ice and fire has formed a wonderful astronomical spectacle.

But the landscape of the planet is more than that. According to the law of thermodynamics, heat will spontaneously transfer from the high temperature region to the low temperature region. The huge temperature difference between ice and fire makes the air convection of the whole planet extremely intense.

Heat and water vapor from the sea water are spontaneously transferred from the warm side to the cold side, which forms a huge gale.

Water vapor condenses when it is cold, forming rainfall. Due to a lot of ice on the shady side and high terrain, most of the rain will return to the ocean. So that's the water cycle of the whole planet.

Global large-scale air convection, so that 15 or 16 typhoon become commonplace, sometimes, these violent hurricanes can reach 18, or even 20!

In order to adapt to this windy environment, almost all the animals on the planet have the ability to dig holes. If you don't hide in the cave when the wind blows, 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. Most animals are very small, crawling on the ground, a bit similar to the reptiles on the earth.

This kind of life only crawls out of the ground for food when it is needed.

In a word, dusk line is still the best living area of the planet, where the temperature is suitable, the precipitation is abundant, and there is a certain amount of light. As long as we can avoid the huge typhoon, life can live well here

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

Send some UAVs or reconnaissance vehicles for field exploration, which will be blown away by the hurricane in a few days, and then crash heavily on the ground and be scrapped.

For poor human beings, every scientific instrument is precious. If there is no way to produce it on a large scale at present, one less instrument will be damaged. So, up to now, human beings still don't know the specific situation of the earth's surface. They can only use satellites to watch and monitor from a distance in the sky

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

On this day, it was a beautiful day, cloudless and rare. The eternal sun in the west, never set.

A life body like a guinea pig emerges from the ground. It is vigilant to observe the surroundings, sniff East and West, and make the action of foraging sensitively.

The yellow and purple dwarf plants, with short leaves and well-developed roots, are called "Aruba" by the Greeks. In ancient times, it used to be a kind of food with little taste, and it was also a kind of raw material for clothes

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

It is not an ordinary creature, but a mechanical mouse!

Powerful electronic eyes began to observe satellites 330000 kilometers away.

There is the earth age, a huge spaceship, a lot of machinery moving back and forth on the surface of the planet

The mechanical mouse recorded all the data.

Yes, there is intelligent life in this galaxy!

Even more, the strength of science and technology is far beyond human estimation.

But fortunately, just like the ultimate prediction of new civilization historiography, most civilizations in the universe are mediocre. The glitzer civilization is also in an unprecedented and irreparable decline"Sir, this is the astronomical data we have taken. Please have a look!"

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

Because of the structure of the body, these intelligent creatures don't need a stool or a bed. Usually when resting habitually squats on the ground, when sleeping will curl up the whole body.

According to human aesthetics, they look like pangolins, with yellow skin covered with scales and two flexible and powerful forepaws. They are good at digging holes.

Of course, at the current level of technology, they don't need to dig holes with their claws. In order to do complicated work better, they usually trim off their nails.

The officer anxiously read the astronomy report, one picture after another, the huge spaceship, and all kinds of traffic equipment on the surface. It's not particularly clear, but it's enough.

Everything shows that this foreign civilization is not a scientific research, but to take root here!

Several other Greeks 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 originated from the solar system, more than 20 light-years away from us."

"They've been sending signals But we didn't reply. "

"It seems to be called Man
