While the entire Venus was carnivaling, the empire's ground control center was tense and busy. Science never leaves anything to chance; you may occasionally discover something, but if you want to understand it in depth, you must invest too much energy.
These are the first few blurry pictures, but in the eyes of real scientists, they have extraordinary value, far beyond the value that ordinary people can see. Through these pictures, you can see how different the structure of this star system is compared to the solar system; see how many planets it has – whether it is stable. Before the subsequent pictures arrive, through simple comparison of these pictures, Roughly calculate the orbit and mass of the planet, etc. Through these photos, we can see the brightness, stability, approximate lifespan, etc. of the star.
Give me a fulcrum and I can lift the whole earth! This statement is somewhat exaggerated.
But among scientists, as long as they master the most basic laws and regulations, and have a little bit of information, they can deduce the entire unknown system - the difference will not be particularly big! This is science. It is a discipline built on a solid foundation and accumulation!
And now, the team led by Zhang Chengye is starting to calculate these overnight. They were so excited that they couldn't sleep at all! Exploring, discovering, and finally utilizing the laws of nature is science. Once you sink into it, you will feel the wonderful passion.
Tick-tock-tock... The clock moved forward quietly, entering June 2, Year 60 of the Imperial Calendar, but everyone was already focused on the picture in front of them. From now on, the detector will send pictures almost every minute. The picture is getting clearer and clearer, and of course getting closer, showing a picture of another star 113 trillion kilometers away from the sun!
"Look, this is a giant gas planet, probably as big as Saturn. Oh, this is the only one discovered so far."
"They have five Earth-like planets. Oh my gosh, four of them are in orbits within Venus, the last one of which is pretty ideal; and one is somewhere in between Earth and Venus... oh Oh, no clearer photos yet, but I’m sure there’s at least one living planet here! ”
"There is no asteroid belt here, and including gaseous planets, a total of six planets have been discovered here. This is the first time such a complete star system has been discovered outside the earth!"
It's already early in the morning. The scientists are not asleep yet. The clearest photos will take at least half a month. Just wait until the detector is inside. Now there are just blurry pictures. But their enthusiasm is unstoppable!
Zhang Jingyuan picked up a printed high-definition picture. This exciting picture looked only two meters square. Not too small. But in this picture, there is only a star the size of a rice grain in the middle, and there are a few invisible black spots around it. If you don't pay attention, you might think it is a problem with the paper itself - although the paper used here is all It is top notch and flawless.
But can we judge so many things just from such a picture? Zhang Jingyuan looked at the busy scientists and suddenly felt that he was a little out of touch with social reality! It can only be said that the current scientific development has exceeded Zhang Jingyuan's cognition. The speed of technological development and explosion is indeed overwhelming! Back on Earth, who would have thought that building a spaceship would require blowing up a moon-like satellite for mining. The spacecraft itself is 117 kilometers long! 117 kilometers, not 117 meters! A whole small artificial steel planet!
The receiver buzzed continuously, and as the detector approached, more and more photos were taken. When the sun came out in the early morning, there were almost one photo every ten seconds.
At the same time, Empire Sync sent the pictures without any processing to the Internet for people to download freely! This is the glory of the entire human civilization. As long as you can connect to the Internet, anyone can download it! Moreover, the superstring communication device sent these data to the earth immediately.
But then the situation changed to updating photos every two hours, hundreds of photos at a time. The main reason is that the superstring communication device is always on, which consumes too much energy! The ones on the ground are fine, but the ones in space are troublesome; especially in the outer space of the solar system, about 30 billion kilometers away, there is almost no sunlight here, and the energy depends entirely on the nuclear fusion reactors it carries - yes, nuclear fusion , the empire's technology is advancing at a high speed; but even the nuclear fusion reactor, after being miniaturized, the energy output is not very high.
However, the citizens of the empire did not complain. In fact, the existing information was enough to make people study frantically for a long time. On June 2 of the imperial calendar, except for a few necessary places such as transportation, medical care, etc., most of the remaining positions are naturally on holiday. People cheered, hugged, and the planetariums everywhere were full. People used radio astronomical telescopes to observe the stars in the distant Cetus constellation. Even if they could only see a point of light here, it could not stop people's yearning for space.
Rich people take their own flying cars or flying saucers to space, rent the empire's space research base, and search for the future residence of mankind in an environment without atmospheric obstruction.
Before the arrival of real clear photos, people were wildly guessing what kind of planet it would be and what kind of race it would be. Is there any intelligent life close to humans? Some people even dug out some science fiction movies from the past.
But many people even create simple animated pictures and so on to satisfy their fantasies.
But when a picture was updated on June 20, the whole world was silent: two planets! Yes, there are actually two planets in this starry sky that meet human standards!
A blue planet with several ant-sized artificial satellites in the sky. There is a large deserted place on the surface of the planet, but more of it is green land and blue sea!
However, people's shock is not over yet. Outside this planet, there is actually another planet. Although the mountains are covered with ice and snow, it still has a dense atmosphere and a few strange plants! ! !
There is life! There is life on the planet! And yes: two! ! !
Soon, the official also gave specific exploration data. As more and more photos are taken, the information scientists have becomes more and more comprehensive, and a completely digital whale constellation appears in front of people!
The illumination intensity of the Cetacean constellation is a little more than 45% of the sun, less than 50%; but because the fourth terrestrial planet is in an ideal position, life is flourishing on it, and the average temperature is about 17 degrees (Earth 15); while the fifth planet , although it is a bit far away, but if you compare the lighting, it is similar to the orbital range between the Earth and Mars, which is more biased towards the Earth. Although it is cold, the average temperature is about 5°, and there is a large amount of liquid water in its equatorial region. Likewise It's a great place to live!
Li Changxing and others looked at each other and saw the surprise in each other's eyes. God is really good to mankind! There are the moon and Venus next to the earth; there are two life planets not far away from the stars that are suitable for humans! Yes, 12 light years is very small in the universe. If the universe were the size of the Earth, then 12 light years would be a few nanometers away! ! !
However, these information alone are not enough; more is needed.
The first living planet has a diameter of 18,000 kilometers, a slightly smaller density, and a mass twice that of the Earth - and a gravity twice that of the Earth. With a little training, it can be used as an ideal place for immigrants.
The second living planet is slightly smaller, with a diameter of 12,000 kilometers, more water, and a mass about 0.9 times that of the Earth. Of course, the same is true for gravity. If you ignore the temperature, this is ideal - you can live in it as soon as you arrive.
However, under the settings of the automated program, the detector did not take too many pictures of Life Planet No. 2. Attracted by electromagnetic waves and so on, it plunged into Life Planet No. 1!
Seeing this, the scientists were suddenly very disappointed. Sure enough, the machine was unreliable and there was no flexibility at all. Hao Hao Hao, the second life planet, actually took two photos!
But then it gets interesting. As the Clairvoyance probe landed, it was first surrounded by some lifeforms with live ammunition. These lifeforms were also upright, but had a long tail. Not to mention their furry bodies, they were only one meter tall. There are two eyes that take up almost half of the face. The face is hairless, and the top of the head is of different colors - it should be like dyeing hair?
And then there was a being wearing gorgeous clothes, constantly making strokes and playing games in front of the detector. He should obviously be a noble or a high-level person in society. However, this final test of the intelligence of life is no longer of much use, because man-made satellites have been seen outside this planet, which is enough to prove that this is a real planet with intelligent life. Well - neither of the two living planets can see natural satellites, it may be a problem with the shooting angle.
But entering the atmosphere also serves another purpose, and that is to test the air!
Groups of data span 12 light-years and return to Venus.
Oxygen content - 33%. So high! Earth citizens exclaimed that oxygen is a resource that humans must pay attention to. Without water, you can live healthily for one day; without oxygen, you can only live healthily for 30 seconds!
Carbon dioxide content - 2%, much higher than the Earth's content, but similar to Venus's carbon dioxide content, and slightly lower.
Nitrogen content - 55%, not bad. It seems to be affected by a wide range of physical structures. The elemental composition of other planets is also similar to the Earth group.
The content of toxic and harmful gases is 0.1‰, and the air quality is higher than the quality of the earth.
Water vapor content: The water vapor content at the detection location is 9%, and the air is very humid, even humid. However, the landing location is at 20° north latitude, which is understandable.
Atmospheric pressure - 1.78 standard atmosphere, which is lower than the current pressure on Venus and completely acceptable.
The local gravity is 1.88 times the Earth's gravity, which is a bit heavy, but it takes a while to get used to it, up to a year. Don't underestimate mankind's ability to evolve.
Local time: Calculating the surface speed, 20 hours a day, the rotation is a bit fast. Comprehensive evaluation: Suitable for human habitation index: 80%, excellent! (Note: The earth is 90% - the percentage of a 10% reduction in air pollution, oxygen content, excessive population, etc.) (To be continued.)
