Chapter 217: A Habitable Planet?

"What are those blue-green patches on Alpha Centauri BB1?"

"Is there a clearer picture?"

"There should be. Pen ~ Fun ~ Pavilion www.biquge.info"

"It still doesn't seem clear enough......"

"It's a pity that the size of the telescope of the Pupil of the Earth is limited, and the performance is far from that of the top telescopes, so it is impossible to get a clearer picture."

"Is there any other way?"

"Only by making the Pupil of the Earth a satellite of Alpha Centauri BB1 can you get a clearer view at a close enough distance."

"However, we can't control the Earth Pupil yet, and it's 2.3 light-years away from us.

......

Yuan Chen, Smith, and Lynn were carefully examining the messages sent back by the Earth Pupil, discussing them from time to time.

Next, they plan to get more information by analyzing the spectral signals sent back by the pupil of the earth.

As previously predicted, both planets have dense atmospheres (both planets have a large enough gravitational pull).

Moreover, they were pleasantly surprised to find that the main composition of the atmosphere of the pale yellow Alpha Centauri star BB1 is carbon dioxide, accounting for about 50.1%, followed by nitrogen, accounting for about 34.8%, and although the oxygen content is not as good as that of the earth (the oxygen content in the earth's atmosphere fluctuates between 21% ~ 25%), there are also 12.9%, in addition to a small amount of argon and other gases.

The atmosphere of another dark brown planet is carbon dioxide, which accounts for about 90.2%, followed by nitrogen, which accounts for about 7.1%, in addition to small amounts of argon, carbon monoxide, methane and other gases.

(Because each chemical element absorbs a very unique coefficient of color, the main components of the gas in the atmosphere can be known according to the physical properties of the gas and its atomic spectrum.) )

"In terms of atmospheric composition, the conditions for the presence of liquid water on both planets are present." "Carbon dioxide in the atmosphere keeps the planet warm and heats the atmosphere, thus creating conditions for the presence of liquid water on the planet's surface, or preventing the planet's surface from freezing. ”

It's not just liquid water, but the atmospheric composition of the yellowish Alpha Centauri star BB1 basically suggests that it is a habitable planet. Although its living environment seems to be much worse than that of Earth.

"Those blue-green patches are probably plants or liquid water." Lynn excitedly continued, "By the way, there are ice caps at the poles! I don't know if it's solid carbon dioxide or ice? “

"It's impossible to tell if the ice sheet is solid water or not, but the blue-green patches are most likely plants or liquid water!" Yuan Haochen also agreed with Lynn's judgment.

"It's amazing! What a beautiful planet, I suddenly felt that the previous hard work was simply worth it. Smith seemed to be in a good mood.

Although they have not yet obtained direct evidence of the existence of water on Alpha Centauri BB1, through comprehensive environmental analysis on this planet, the possibility of liquid water on Alpha Centauri BB1 is extremely high!

From a broad perspective of the universe, hydrogen accounts for more than 70% of the universe, and oxygen is also one of the most common stellar fusion products.

Therefore, the amount of water (ice) in the universe is inherently large.

For example, Europa in the solar system has a lot more water (mostly ice) on it than on the entire Earth.

Scientists have analyzed that when the solar system first began to form, the water content of the inner and outer solar systems should be about the same.

But with the formation of the primordial sun, which began to glow and heat, the water in the inner solar system began to be destroyed. Due to the small mass of hydrogen, it is easy for planets to escape if they are not massive enough, so that a large amount of hydrogen is gradually driven out of the inner solar system.

Therefore, the lack of water on Mercury, Venus, and Mars is actually a lack of hydrogen, and oxygen is everywhere.

In the hundreds of millions of years when Mars was first formed, there was still a lot of water on it, and because the temperature on Mars was higher than it is now, a huge ocean was formed on the entire planet, and there are still traces of water currents to this day. This is also the reason why 2.1 billion years ago, the alien doctors chose both Mars and Earth as the goals of the [Genesis Project].

However, most of the water on Mars has indeed been lost today.

Going back to Alpha Centauri BB1, first of all, it happens to be in the habitable zone, and secondly, its total mass is large enough, its gravitational pull is sufficient, and it is likely that it also has a magnetic field, so the water molecules can be well protected, and even if the hydrogen is destroyed, it will not easily escape.

Most importantly, 2.1 billion years ago, the Alpha Centauri galaxy gave birth to a cosmic civilization of level II or higher.

Therefore, the discovery of a habitable planet here is certainly not an accidental event, but an extremely high probability event.

......

"It's really likely to be a habitable planet. However, judging from the appearance, it is clear that Alpha Centauri 1 does not have an advanced cosmic civilization world. Yuan Haochen continued slowly, "So, we were worried too much before. ”

"It looks more like a desert, maybe it's really a barren world with extremely few resources." Lynn said.

"Then let's call it the Sand Star first, what do you say?" Smith suggested.

"Sounds apt." Yuan Haochen nodded in agreement.

"What about the other planet? Look at the color, and the texture, you don't think it's like a pile of excrement......"

"Dung Star?" Smith smirked.

“shi~t? Come on, we're scientists. Although the colors did look similar...... Lynn forced a smile, looking at his expression made one suspect that he might have thought the name was still good in his heart.

"Then the dung star, it's too similar indeed."

Hara pretended to be serious and stared at the planets in the image, looking up and down, the more he looked at it, the more it looked like cow dung that was commonplace in the village when he was a child.

"Hahaha~"

The other two thought that it was indeed the same thing as the hero, so they laughed out loud......

Although the possibility of an advanced extraterrestrial civilization has been largely ruled out on Sand Star, as a habitable planet, the possibility of life is very high.

"Can the Pupil of Earth detect the signal of life on the Sand Star?"

Lynn knew relatively little about the Pupil of the Earth, so he asked Yuan Chen.

"Perhaps, it remains to be seen."

Yuan Haochen is not completely sure about this.
