Scientists found a “large earth”, about 39 light-years away from the solar system, may exist life

The earth is a planet of life. As the only intelligent human being on this planet, human civilization has ushered in a leap forward development since it entered the road of scientific and technological development. With the help of science and technology, human beings have finally realized their dream of flying to the sky, walked out of the earth and began to explore the universe.

For people who have just stepped out of the earth, the universe is still a completely strange world. We know nothing about the mysteries here. Among the numerous mysteries of the universe, the most concern for scientists is the existence of extraterrestrial life and extraterrestrial civilization. Maybe before human beings walk out of the earth, we will think that human beings are the only intelligent life in the universe, and the earth is the only life planet.

However, when human beings go out of the earth and see the vast universe, this kind of cognition is completely broken. More and more people believe that the existence of extraterrestrial life and extraterrestrial civilization is just due to the limitation of human science and technology. We can’t go out of the solar system and send spaceships to observe the planets that may have life at a short distance.

Before human beings have the ability to go out of the solar system, the only tool that scientists can rely on to explore extraterrestrial life and extraterrestrial civilization is the astronomical telescope, which is one of the greatest inventions of human beings. It allows us to see the distant depths of the universe. Before we have the ability to field survey, we can also find and observe galaxies, stars, planets and other aspects of the universe Quasi celestial bodies.

What scientists most want to explore and look for through astronomical telescopes are those earth like planets that may have life. They are looking for earth like planets that are very similar to the earth. Such planets not only have a high possibility of survival, but also are the spheres for human beings to carry out interstellar migration in the future.

With the help of powerful telescopes, scientists have found many earth like planets, some of which are similar to the earth and very high, LHS 1140b is one of many earth like planets similar to the earth. It is called “large earth” by scientists. Scientists call it because it is very similar to the earth and its mass is close to 7 times that of the earth.

LHS 1140b was observed by astronomical instruments as early as 2014, but it did not attract anyone’s attention at that time. It was only when Jason Ditman, who worked at Harvard Smithsonian Center for Astrophysics, reanalyzed the data that the scientific community found the existence of LHS 1140b.

In order to confirm the existence of planets, Ditman led the research team to use four telescopes. Three of them are professional telescopes, and the remaining one is operated by a cremated enthusiast in Perth, Australia, who is responsible for observing professional telescopes when they are affected by bad weather. The result of the joint observation is the discovery of a dim small star and the dwarf planet LHS 1140b revolving around it. On April 19, 2017, the newly discovered planet was named LHS 1140b.

Preliminary observations show that the earth like planet is about 39 light-years away from the solar system. It is also a rocky planet like the earth, and it is located in the habitable zone of the main star. It can receive sufficient stellar light, and the temperature of the planet may be similar to that of the earth. Such a perfect rocky planet might have an atmosphere and liquid water.

Through the observation of giant telescopes, scientists found that there may be oxygen molecules on the surface of the planet, atmosphere, liquid water and oxygen molecules. The combination of the three is the prerequisite for the birth of life. Therefore, scientists speculate that there may be life on the planet, and it is still a mystery whether it will be ordinary life or intelligent life like human beings.

However, scientists speculate that there may be oxygen molecules on the planet. If there is a large amount of liquid water, the ecological environment of the planet may be similar to that of the earth, and the possibility of the birth of similar life in a very similar ecological environment will be great. At the same time, this planet may also be an alternative planet for human future interstellar migration.

You know, when human beings plan to immigrate in the future, the planet they choose must be very similar to the ecological environment of the earth, so that human beings can survive on such a planet. If this planet is also a life planet, but the ecological environment is different from that of the earth. For example, human beings need oxygen to breathe, while life on other planets breathes methane.

No matter how beautiful the scenery of such a planet is, no matter how good the ecological environment is, without oxygen for human beings to breathe, it is not suitable for human survival. Some people may think that other planets need water and oxygen to give birth to life. But the real situation may be different from what we expected. The birth of life on a planet can’t do without an atmosphere, but it’s hard to say whether it needs water and oxygen.

Maybe there is no water in the ecological environment of some other planets, but there are other liquid oceans, and there is no oxygen, but such planets may also give birth to life, or even intelligent life. For example, Titan in the solar system has a thick atmosphere and a liquid ocean, but the composition of the liquid ocean is methane and ethane. There is no oxygen on such a planet, only a large amount of methane gas.

In the eyes of scientists, Titan is also a planet that may have life, because it has a thick atmosphere and its own ecosystem, which meets the conditions for the birth of life. If Titan gives birth to life, it will be completely different from life on earth. It can be seen that the ecological environment very similar to the earth in the universe is only one kind of ecological environment that may give birth to life, and there may be many other ecological environment structures that may give birth to life.
