Venus in ancient times may have given birth to life. Why has it become a hell planet now?

In ancient times, due to the lack of astronomical observation equipment, people could only observe the stars by naked eyes. Among the stars visible by naked eyes, one star received the most attention, which is Venus.

Venus is called Changgeng, Qiming, Taibai or Taibai Venus in ancient China. Ancient Greek mythology is called Aphrodite. The ancient Romans called it Venus. In the early morning, it is called “Qiming” and appears in the eastern sky; in the evening, it is called “Changgeng” and lies on the west side of the sky. It reaches the maximum brightness just before sunrise or after sunset, and its brightness is second only to the moon in the night sky.

It is because Venus is very bright in the sky, so the ancient astronomers paid more attention to it, so many legends about Venus were born. With the advent of the era of science and technology, when we have astronomical telescopes, we can see the extraterrestrial sky through the earth. At that time, we have a preliminary understanding of Venus. We know that it is the closest planet to the earth, which is very similar to the size, volume and mass of the earth.

Therefore, after humans walked out of the earth, the first planet to explore was Venus. At that time, scientists believed that Venus was almost the same as the earth in geological structure, and also had a very thick atmosphere. They believed that Venus might have the conditions to breed life. Moreover, Venus is the closest to the earth in absolute distance, and the probe only takes about three months to arrive.

In order to explore the mystery of the life of Venus, the Soviet Union launched many detectors to Venus in the last century. When the detector reached the orbit of Venus, it was found that the environment of Venus was completely different from what we had originally imagined. Although Venus had a very thick atmosphere, the main component was carbon dioxide, which reached more than 90%.

The high level of carbon dioxide makes the greenhouse effect of Venus particularly severe, resulting in the surface temperature of more than 460 degrees Celsius. In addition, there is a thick layer of acid rain in the atmosphere of Venus. Acid rain often falls on the surface of the planet, which aggravates the surface environment. Such Venus is a hell planet in the eyes of scientists.

The harsh environment of Venus also hindered the landing of the probe. Due to the thick atmosphere of Venus and the acid rain layer, it is difficult to observe the surface of Venus through the orbital probe. It could only land on the surface of Venus, but several attempts by the Soviet Union ended in failure. Even if they barely landed on the surface of Venus, they could hardly survive for two hours.

The harsh environment of Venus forced scientists to give up exploration and finally focused on Mars, another neighbor of the earth. Therefore, in recent decades, what we can see is basically about the major discoveries made by the probe on Mars, but rarely mentioned by Venus scientists.

Many people think that scientists don’t explore Venus because it has nothing to study. Is that true? Of course not. In fact, in the minds of scientists, the research value of Venus far exceeds that of Mars. You should know that Venus is the sister planet of the earth. There are too many similarities between them. In the line of sight of astronomical telescopes, Venus and the earth are not different except for their colors.

Since Venus is so similar to the earth, why is its ecological environment so different from the earth? Why did Venus become like this? Some scientists even believe that Venus in ancient times may be as beautiful as the earth, and life may have been born.

If Venus in ancient times had given birth to life, is there any life on it now? Many people may think: the surface temperature of Venus has reached above 460 degrees Celsius. How can there be life on such a bad hot planet? In the early days, such cognition was generally accepted by the scientific community. However, with the exploration of life on earth by scientists, especially the discovery of life in some extreme environments, our cognition of life has changed greatly.

The tenacious survival ability of life is far beyond our imagination. The earth is a planet of life. In addition to a large number of life in suitable environments, there are also life in some extreme environments. For example, the water bear can survive in different harsh environments. Even if it is put into space without any protection, it can still survive.

The earth can give birth to indomitable life like water bear, so it is possible to give birth to life under the harsh environment like Venus. Scientists have no definite answer to the question that Venus has changed from a beautiful planet in the past to what it is now. Some people think that Venus is closer to the sun, and the rising temperature of the sun leads to the rising temperature of Venus.

However, this view has not been supported by many people. More people think that the reason why Venus has become like this is related to more than 90% of the carbon dioxide in Venus’ atmosphere. As long as we find out what makes the carbon dioxide concentration in Venus’ atmosphere so high, we may be able to uncover the truth of Venus’ drastic change.

Some scientists believe that the high content of carbon dioxide in the atmosphere of Venus may be related to a large number of volcanic eruptions. According to the preliminary detection of the probe, Venus can be called a volcanic world, where there are too many volcanoes. It can be said that there are many volcanoes, and it is the planet with the largest number of volcanoes in the solar system. More than 1600 large volcanoes and volcanic features have been found. In addition, there are countless small volcanoes. No one has calculated their number. It is estimated that the total number is more than 100000, or even 1 million.

The probe found that the surface of Venus is very young, which indicates that the geological activities of Venus are still very active. It is possible that a long time ago, Venus erupted a large area of volcanic eruptions, and a large amount of carbon dioxide produced by volcanic eruptions was released into the atmosphere, resulting in more and more severe greenhouse effect and higher and higher surface temperature.

The ultra-high temperature continuously evaporates the liquid water on the surface. Due to the continuous volcanic activity, the concentration of carbon dioxide in Venus’ atmosphere becomes higher and higher. Finally, it breaks through the critical point and completely changes Venus’ atmospheric structure. Similarly, a large amount of water evaporation reacts with carbon dioxide and forms an acid rain layer.

Of course, the above are just some guesses of scientists. Venus has too many mysteries to be solved. For example, why does Venus have no magnetic field and its rotation direction is completely opposite to other planets? You know, in our understanding, the sun rises in the East and falls in the west, which is determined by the rotation direction of the planets.

Among the eight major planets in the solar system, the rotation directions of the seven major planets are the same, but Venus is the only one in the opposite direction. So on Venus, you will see that the sun rises in the West and sets in the East. How such a special rotation direction was formed is still a mystery.

It can be seen that the secrets of Venus are far more than those of Mars, and scientists also think so. Especially in recent years, after sorting out and analyzing the large number of Venus probes in the Soviet Union in the last century, scientists have made a major discovery, that is, scientists have found that there seems to be an object moving on the surface of Venus, which is more like a living thing than a natural thing Things.

With the continuous improvement of science and technology, scientists are more and more eager to explore Venus. It is possible that in the near future, humans will return to Venus from Mars. At that time, many probes may land on Venus and start a series of exploration and research. At that time, we may be able to uncover the mystery of Venus hot, but also understand the history of Venus and whether there is life now.
