Venus immigrants English

Everyone has always been concerned about whether there are traces of ancient civilization on Venus. Many friends think that Venus may have once had a livable environment. Venusians destroyed the environment and ran away. So the traces of Venus civilization in various media are always sought after!

However, in September of 14, a discovery jointly announced by MIT, Manchester University and Cardiff University was really frightening, because this joint research team found phosphine gas in the atmosphere of Venus that can only be produced by the metabolic process of life, which means that there may be life with a temperature as high as 464℃ on this surface!

How can the conditions of Venus be so extreme? Why is there life?

Venus was once one of the most desirable destinations for human beings. Anyone who had contact with aliens can confirm this. For example, the intimate contact of the famous third person, george adamski, claimed to have received the Venusians at1952165438+1October 20th, but after the incident, the Venusians requested to delete the photos and erase all traces!

Indeed, his remarks were quite confusing at that time, because Venus, which is about/kloc-0.08 million kilometers away from the sun, is the closest planet to the earth, with a radius of 605/kloc-0.8/kloc-0.0 kilometers, which is only about 320 kilometers smaller than the earth, and it is also on the hot edge of the solar system's livable zone. That is to say, according to speculation, Venus will only be smaller than the earth.

Therefore, many sci-fi movies and novels of that year were based on the theme of emigrating to Venus, and supporting posters also portrayed Venus as a more comfortable planet than the earth. Humans really dream of emigrating to Venus and enjoying the legendary Venus world!

However, on the day of1962,65438+2 and 14, when Mariner 2 flew over Venus at an altitude of 34,773 kilometers, the dream of human beings moving to Venus was shattered, because according to the data returned by Mariner 2, scientists determined that there was a carbon dioxide atmosphere with a thickness of 60 kilometers on Venus, and the surface temperature of Venus was as high as 425℃ (in the following,

Red and white Venus

In addition, it is not only high temperature, but also the atmospheric pressure caused by carbon dioxide with this thickness is as high as 92Bar (92 times atmospheric pressure), and the pressure cooker that can stew bones on the earth is only 1.8-2 atmospheric pressure! Therefore, when humans have determined the situation of Venus, the search for life on Venus has obviously given up, because no one will believe that life can exist in such a high-pressure and high-temperature environment!

MIT, Manchester and Cardiff University jointly announced the discovery of signs of life on Venus.

On September 14, the joint team announced the discovery of phosphine gas (PH3) in the atmosphere of Venus, which is a gas composed of one phosphorus atom and three hydrogen atoms and is closely related to life on earth. For example, microorganisms in penguin intestines can produce phosphine (penguins fart with phosphine), and microorganisms in anoxic environments such as swamps are also related to phosphine! Of course, it can be synthesized artificially, but without these things on Venus, life cannot exist in such a high temperature environment. How is it formed?

Is there really life that can withstand the temperature at which zinc can melt? This is definitely big news! In fact, this is not the case, because before the discovery of phosphine, a fart suspected of Venus' life, NASA scientists have long suggested that there is an area with suitable environmental temperature and possible life 50-60 kilometers above Venus' atmosphere. The most important thing is that the oxygen concentration here is relatively high!

More interestingly, this result was found in the data observed by james clerk maxwell Telescope in June 20 17. In order to verify this conclusion, this observation was reconfirmed in March 20 19 by using the Atacama Large Millimeter/Submillimeter Array (ALMA)!

In addition, the ALMA verification found that the proportion of phosphine in the atmosphere of Venus was higher than originally expected. This verification also ruled out that Venus was caused by volcanic eruption or meteor decomposition in the atmosphere.

Jane Greaves, a professor at Cardiff University, said that not emphasizing the detection of phosphine is not a strong evidence for the existence of life. But they tried many chemical routes of abiotic synthesis of phosphine and found that this possibility was extremely low, less than four to eight orders of magnitude!

NASA: I'm a little scared. I have to check it out!

What will these lives be like? I remember a sci-fi movie showing a giant whale soaring in the atmosphere. Theoretically, it is impossible to exist, but on a planet with high atmospheric density and low gravity, such as Titan, its atmospheric pressure is twice that of the earth, but its gravity is only 1/6 of that of the earth, so a person should be able to fly with wings on his arms!

What will life be like on Venus? Soaring in the atmosphere? Flying Venus bird? After all, the surface of Venus is close to 500 degrees Celsius. Once it lands, it won't last a second! Moreover, there are sulfuric acid clouds in the bottom atmosphere, which may kill the Venus Bird before landing!

Most likely, there are a large number of microbial communities in the atmosphere of Venus, and it is difficult for us to guess what kind of life mechanism process these microorganisms will have, so the most important task at present is to launch a detector to sample in the atmosphere of Venus!

In 2026, NASA's Venus probe set off.

Earlier this year, NASA put forward a new concept of Venus probe, which is called "Da Vinci+"project. It consists of an orbiter and an atmospheric probe. It is expected to leave for Venus on 20 16! After reaching Venus' orbit, the orbiter will orbit Venus, and the probe will carry equipment deep into Venus' atmosphere. Nothing ventured, nothing gained. NASA is determined to win this time!

During the 63-minute descent, Leonardo da Vinci will collect and send back the measurement data of Venus' atmospheric composition.

However, I would like to remind you that in the plan to explore the brain hole of Venus, "Venus Cloud City" is definitely worth mentioning. As early as 20 18, NASA scientists put forward the idea of using airships to travel in the atmosphere of Venus. The environment here is similar to the surface of the earth, and the atmosphere provides a cosmic ray barrier, plenty of sunshine and high temperature below. This is really a paradise!

Of course, it's not that easy to achieve. It is a whimsical plan to launch a huge airship from the earth to Venus. Of course, if life can really be found on Venus this time, it is foreseeable that NASA will pick up a similar plan, because finding life on other planets in the solar system is definitely the biggest scientific discovery in 2 1 century!
