Evidence has been captured that life exists on Venus. In the cloud, substances made by microorganisms were captured. Scientists believe that, unlike the harsh surface of the environment, life on Venus is likely to exist in clouds.
On the 14th (local time), an international joint research team led by Professor Jane Greaves from Cardiff University in the UK wrote in the international journal ‘Nature Astronomy’ on the 14th (local time). It captured phosphorous hydride in the air above. “
Phosphorous hydride is a substance that combines one phosphorus atom and three hydrogen atoms, it is synthesized in a terrestrial laboratory or made by microorganisms that live in places where oxygen is scarce, such as a swamp. Even on Venus, the researchers found that the microbes in the cloud could have produced phosphorous hydride.
“It is incomprehensible to find phosphorous hydrogen in the environment of Venus,” said Dr. David Greenspoon of the Arizona Institute for Planetary Sciences. “It means that hydrogen will continue to form and replenish itself because it decomposes quickly.”
◇ Clouds are more suitable for living than the surface.
Hydrogen is present in the depths of the giant planets in addition to the body of Xiang Myung. But Venus doesn’t have such an environment, the researchers said. Additionally, it is possible that asteroids collide or are generated by volcanic activity, but the researchers said it was difficult to produce the amount of hydrogen from phosphorus from this observation in the process.
This time, the researchers captured about 20 phosphorous hydride out of a billion air molecules in a cloud 53 kilometers above the surface of Venus. It may seem very small, but that amount is in a watery cloud filled with acidic solutions, the researchers said.
Also, since phosphorous hydride decomposes within 16 minutes, the observation that this amount of phosphorus continues to mean that phosphorous hydride continues to replenish in the cloud.
In an interview with a British New Scientist, Dr. Clara Susa-Silva of MIT, a member of the research team, said in an interview with a British New Scientist: “We considered all the processes that could produce hydrogen, but in any case, we concluded that we could not produce as much as we observe. “
Two possibilities remain. One is that something we don’t know is happening in the clouds of Venus, or that life, like Earth, is producing hydrogen and phosphorous.
The idea that life could exist in the atmosphere of Venus has existed. The surface of Venus has an atmospheric pressure 95 times that of Earth and a temperature of up to 477 degrees Celsius, making life difficult for life. However, the air pressure and temperature above the surface at 50 km are similar to those on Earth, which is why it is known as an environment that allows life to exist.
Professor Paul Bayern of North Carolina State University in the United States said: “Previously, we had only inferred that life could exist in theory, but now we have identified hydrogen.”
