Experts say it is impossible to move to Venus. Why?

Whenever people look up at the starry sky, they often can't help but fantasize: Is there life on other planets in the universe? Is it possible for human beings to realize "interstellar travel"?

It is reported that astronomers have detected phosphine in the atmosphere of Venus. This gas was detected in the atmosphere of Venus, which means that there may be life on Venus.

Is that really the case? How likely is it that humans fantasize about "moving to Venus"?

The possibility brought by phosphine needs to be clarified. What does it mean to detect phosphine in the atmosphere of Venus this time?

Some astronomical scientists observed through telescopes that a gas called phosphine was detected in the acidic clouds of Venus, thus speculating that there may be signs of life in Venus.

"In fact, before this, humans have found phosphine in the atmosphere of Jupiter and Saturn. But in the atmosphere of Jupiter and Saturn, phosphine can exist stably for a long time. So it is not surprising that there are phosphine on Jupiter and Saturn. " Wang Shuang, an associate professor at the School of Physics and Astronomy of Sun Yat-sen University and a famous popular science writer, said.

He also said, but Venus is different. Venus's atmosphere is strongly acidic and will react with phosphine. Therefore, phosphine was detected in the atmosphere of Venus, indicating that there is some mechanism that can continuously produce phosphine on Venus.

"Under normal circumstances, phosphine is produced in two ways. One is natural phenomena, such as lightning and volcanic activity; The other is biological mechanism, that is, the life activities of some anaerobic microorganisms can produce phosphine. Wang Shuang said, "But the problem is that the amount of phosphine produced by natural phenomena is very limited. In other words, it is difficult to explain why there is a large amount of phosphine in the atmosphere of Venus with natural phenomena. "

Therefore, some people speculate that there will be some anaerobic microorganisms in the atmosphere of Venus. According to Wang Shuang, this is only a theoretical possibility, far from confirming the existence of life on Venus. Even if there is life, it's just some alien microbes, and aliens can't talk about it at all.

But the findings of this study still have important scientific significance. Wang Shuang said, "Why can phosphine be continuously produced in the atmosphere of Venus? What is the reason behind it? This is worth exploring in science. "

What is the possibility of moving to Venus? It is worth noting that many people are so excited when they hear that phosphine has been detected in the atmosphere of Venus, largely because they have a romantic imagination in their hearts: Will there be aliens on Venus? Can I travel to Venus in the future?

This kind of imagination is not completely illusory. In the popular science work "Odyssey of the Universe: Walking in the Solar System", it is mentioned that Venus has long been regarded as the sister planet of the earth because they do have many similarities.

For example, the volume of Venus is about 85.5% of the earth's volume, while the mass of Venus is about 81.5% of the earth's mass; In other words, both are about the same size and quality. So many people fantasize that maybe one day humans can immigrate to Venus. The ideal is full, but the reality is very skinny. The real Venus, its environment is more like a terrible "hell".

Horrible Venus Environment In ancient times, Venus had several names. When it appears in the eastern sky at dawn, it is called "morning star", and when it appears in the western sky at evening, it is called "Chang Geng star". However, Venus, which looks so bright and beautiful, has an extremely harsh environment.

Wang Shuang introduced that human beings have sent probes to Venus many times, and then learned about the hellish environment of Venus. Venus has three worst places.

The first is high temperature. The average temperature on the surface of Venus is about 460℃, which is higher than that of Mercury. Landing on Venus is equivalent to entering a burning oil pan. The second is high pressure. The atmospheric pressure on the surface of Venus is about 92 times that of the Earth. To give a simple example, this is equivalent to putting a tank on a person. Then there was the terrible acid rain. There will be a large-scale sulfuric acid rain on Venus from time to time. It's really concentrated sulfuric acid, which can disfigure people.

Wang Shuang said that the main culprit in turning Venus into this hellish appearance is the "greenhouse effect". In the atmosphere of Venus, the content of carbon dioxide is as high as 96%. The content of this greenhouse gas is so high that the "greenhouse effect" on Venus is completely out of control, creating this terrible environment of high temperature, high pressure and strong corrosion.
