Is there life on Venus? This idea, which has been put forward before, has been seriously discussed in science. The research team, who published the paper in natural astronomy, put forward their own opinions. In their astronomical observations, they all found the biological marker phosphine in the atmosphere without exception.
This means that phosphine is present on Venus. As for this phenomenon, the team of researchers explained it. First, there is a chemical reaction on Venus that we never knew. These reactions dissolve and catalyze, and unknown chemical reactions occur, thus producing phosphine. Second, there is life in the grassroots of Venus, which is the life that creates these gases.
The exploration of human beings is always moving forward, especially the fantasy and exploration of extraterrestrial life. From the moon, Mars and beyond the Milky way, human beings are exploring the outer edge of the universe. But speaking of Venus, we are very close neighbors, but there is not much news and fantasy. After all, scientists all know that many conditions for life to survive require the right temperature, the right water, the right air and so on.
So at this stage, the goal of human exploration is a habitable place or an extraterrestrial planet, and Venus in the sun, the temperature is as high as 500 degrees, and a little, the air is extremely dry – a thick atmosphere, not only carbon dioxide, but also quite a lot of sulfuric acid. From the perspective of habitability, Venus is definitely not a good choice.
Although the weather conditions of Venus are so bad, there is still a relatively mild area in the atmosphere.
This area is very small, and 60 kilometers away from the surface of Venus, and about its pressure, in this respect, we know the data is very similar to the earth’s environment, the temperature is below 50 degrees, although there is still sulfuric acid cloud, but there are already microorganisms on the earth that can survive in the sulfuric acid environment, so scientists began to guess whether it is on Venus Is there such a creature that can not only meet the living conditions here, but also endure to get the sulfuric acid cloud?
If it does exist, it will only be in this atmosphere.
So what kind of method should be used to explore the existence of creatures on Venus? It turns out that the researchers used some kind of biomarker – it’s a molecule that’s produced by the metabolism of an organism, and no non living organism can create it
. Phosphine is a kind of poisonous gas emitting a bad smell. On earth, this kind of gas generally exists in the atmosphere, but its content is very low, which can be ignored. It has only two sources, one is the product of anaerobic biological metabolism, the other is human industrial and agricultural production.
In other words, both of them are closely related to life. If there is no life on the earth, there will be no such gas.
Of course, different planets should be analyzed according to different facts. If it is in Saturn and Jupiter, it is entirely possible to produce phosphine because of their extremely high internal temperature. So although scientists have found this gas on two planets, they are not very surprised by the results.
But Venus is different, because it is a rocky planet, different from Jupiter and Saturn, so according to common sense, it should not appear phosphine.
It is confirmed that there is phosphine on Venus, so the question is, how did these things come from? First of all, with today’s science and technology, no team can directly prove that this is the trace left by life activities, so what the team can do is to find out all the possibilities, delete the most impossible, and the rest is the most likely truth no matter what.
According to the feedback of NASA’s simulation research, we can know that perhaps Venus had a very mild climate in its early days, and even had a liquid ocean. Such a warm and humid environment may be able to breed some simple Venus creatures.
Therefore, it is still too early to confirm or object to the existence of life on Venus only by the evidence on hand. Moreover, there is still a great controversy in the astronomical circles about how phosphine is produced. It can indeed become a marker of life activities, but the source of phosphine still needs to be further explored.
At the call of many scientists, NASA is also considering re exploring elaborate details.
At that time, maybe we will get a new understanding of Venus’ astronomy, chemistry and physics.
