Is there life on Venus? Scientists found highly toxic gases, or become evidence of the existence of extraterrestrial life

When human beings just started space exploration, there was a “alien fever” in the society. Everyone hoped to find the so-called “alien life” in the process of space exploration. So during this period, there appeared many sci-fi films and TV works, a large part of which was the human fantasy of “Martian”.

When we have not carried out space exploration, but only through earth’s telescopes to observe Mars, many people have found crisscross ditches on the surface of Mars, and believe in the existence of intelligent civilization on Mars. However, when our probe really landed on the surface of Mars, and collected a lot of information, it turned out that Mars is a barren desert planet, without any intelligent civilization, or even simple microorganisms.

People have disillusioned the Martian, but today scientists are surprised that there may be life on Venus, another neighbor of the earth. A research report was published in the journal Nature astronomy and spread all over the world in a few hours. The authors are a group of scientists from Cardiff University in the UK and Massachusetts Institute of technology in the US. Using the James mackwell telescope in Hawaii and the liatakama giant millimeter wave antenna array in Chile, they found phosphine in the atmosphere of Venus.

What is phosphine (PH3)? This kind of toxic substance is very common on the earth. It is usually the waste produced by organisms. Of course, it is mainly anaerobic bacteria and microorganisms. Therefore, when scientists are looking for extraterrestrial life, phosphine is often regarded as “the symbol of life”. Through the abiotic mechanism, Venus can also produce hydrogen sulfide, but according to the model calculation, it will not produce much hydrogen sulfide, so scientists found that hydrogen sulfide can reach 20 ppb.

So the scientific team published this paper very reluctantly, and the scientists think it’s not easy to come to such a conclusion, because it’s a big event. If it turns out to be true, it will open up a new history, such as those that can be remembered after thousands, tens of thousands or even hundreds of thousands of years. If it turns out to be true, it will be the first time that extraterrestrial life has been discovered on earth. What’s the significance of this?

For most people, Venus is a “human purgatory”. Within a year, the temperature is as high as 500 degrees Celsius, and the dense atmosphere is equivalent to the ocean thousands of meters deep on earth. However, the acid rain erupted by volcanoes is not like a hotbed of life.

Researchers found that at an average height of 48-60 km in Venus’ atmosphere, phosphine is considered to be the hotbed of life, with an average temperature range of – 6.7-100 ℃. This temperature range covers the most suitable temperature for the growth and development of life, and phosphine is the most direct and important evidence for the survival of life.

There is no doubt that in order to be sure that there is life on Venus, scientists need more evidence, preferably captured directly. However, it is very difficult to make the detector work on Venus for a long time, especially to launch equipment similar to balloon detector to make it suspended above the atmosphere of Venus.

This discovery has sounded the clarion call for human beings to go to Venus. Of course, “Venusians” are unlikely to appear. At most, they are just some simple microorganisms. But if there is such a discovery, it will be important enough.
