Why do scientists always believe in extraterrestrial life? These discoveries will serve as evidence

In the universe, is there no life on any other planet except the earth? In the 21st century, although this question has not been answered, more and more scientists believe that the answer is yes. Recently, an article published in the Spanish newspaper Le Nationale presented some evidence of the existence of extraterrestrial life.

Why believe in the existence of alien life?

That starts with the big bang. According to modern research, about 13.8 billion years ago, the singularity explosion made the universe appear. Since then, with the evolution of stars, new elements have been continuously injected into the universe. About 5 billion years ago, at the edge of the Milky way, the sun was conceived, and the solar system has become the only living star system so far.

However, after entering the 21st century, through the observation of the universe, we find that neither the solar system nor the earth is the most perfect existence in the universe, and the climate environment of many planets is better than that of the earth. That is to say, if a planet is old enough, there is a good chance of life on it.

At the same time, many discoveries in the universe have also proved the existence of extraterrestrial life. For example, scientists have discovered organic matter in the universe. They believe that comets carry these seeds of life and sow them in the universe. Then, if the environment on earth is suitable, life will appear.

The process of exploring extraterrestrial life is not easy, but it is enough to make scientists excited. Every discovery also makes scientists far away from the answer. In particular, not long ago, a high concentration of phosphine was found in the atmosphere of Venus, which makes extraterrestrial life “ready”.

Proof 1: phosphine on Venus

Venus is the closest planet to the earth in the solar system. Its size and mass are similar to that of the earth. Therefore, Venus is called “sister planet of the earth”. However, due to the close distance between Venus and the sun, Venus becomes very hot. Sulfuric acid rain occurs all year round, and the temperature chamber effect bursts out, which also makes Venus known as “hell planet”. No one thinks that it can be so hot in Venus There is life in the environment of fear.

However, phosphine was found on such an unpopular planet. On this planet, scientists found that only biological activities produce phosphine, which can not be synthesized in the natural environment. This means that phosphine on Venus is likely to be related to life.

Where is life on Venus? The study found that there are habitable areas in the upper atmosphere of Venus that are very similar to the earth, and the temperature and pressure are very similar to the earth. Therefore, the researchers believe that there are anaerobic bacteria in the atmosphere of Venus, which are active in the atmosphere and produce phosphine through metabolic reaction.

Second: the presence of carbon 14 on Mars

Although human beings have never been to Mars, the exploration of Mars began in the last century. In 1976, NASA’s Viking Mars probe successfully landed on the surface of Mars and found carbon 14 in methane in Martian soil samples.

At that time, many people believed that there were microorganisms on Mars, but this problem has not been solved. Until 1996, the discovery of Martian meteorites in Antarctica, as well as the existence of microorganisms, led scientists to study Martian life again.

Similarly, because of these discoveries on Mars, scientists have chosen Mars as the “second home” of human beings. After entering the 21st century, many probes have gone to Mars, hoping to solve the mystery of Martian life. The “tianwen-1” and “perseverance” Mars probes launched in succession in July this year have also brought the task of looking for life. It may not take long for life to disappear The secret will be revealed.

Proof 3: the “underground ocean” of the Jupiter system

In the 21st century, scientists have discovered a new “fact”, that is, life exists not only on planets, but also possibly on satellites, because through observation and research, organic matter has been found on Europa. Jupiter is the largest planet in the solar system. There are dozens of moons around it, among which Europa, Ganymede and Callisto are the most likely planets for life in the eyes of scientists.

Not long ago, Russian scientists found that Callisto may be more suitable for human migration than Mars, because it contains not only oxygen, but also liquid water.

Because Europa’s “underground ocean” may be larger than the earth’s ocean, NASA’s exploration focus does not exclude the existence of fish and other life. Therefore, Europa is regarded as the most promising planet in the solar system except the earth.

With the development of human beings, people’s understanding of the universe is also deepening. From not believing that there are other planets outside the solar system to now discovering thousands of exoplanets, human beings are closer to the earth.
