Finding amino acids in the asteroid sample, is the life of the earth brought by the asteroid?Fail to conclude

The earth was formed about 4.6 billion years ago, and life did not exist on the earth from the beginning.

It is generally believed that the life of the earth originated from 3 billion years ago. As for how life originated, no one could give a satisfactory answer. The simplest form of life of single -cell life is the simplest single -cell life. Its complexity is far better than the precision instruments created by any human beings. What about forming? Life is composed of cells, and the most important substance in cells is protein, so protein is also called the basis of life. Protein is a macromolecular substance that constitutes its basic unit is amino acids, and amino acids are organic compounds containing alkaline amino and acidic hydroxyl groups.

How is the original amino acid on the earth formed?

No one can say clearly, but there has always been such a statement in the academic community, that is, the early earth's early amino acids were brought about by meteorites that broke into the earth. This statement is not speculative out of thin air, but has some basis, because humans have detected the existence of amino acids in the meteorites falling into the earth. However, this does not show any problem, because the meteorite falling into the earth has suffered full contact with the earth's atmosphere, and it was polluted by the environment after falling on the ground. It is still contaminated on the earth. However, there are some changes in the situation, and humans have finally determined that there is amino acids on celestial bodies outside the earth.

In 2014, Japan launched a small asteroid detector called "Bird 2". Its goal is a small planet named "Dragon Palace" located outside the asteroid belt.

After a 4 -year flight, 2018 Bird No. 2 finally approached the small planet with a diameter of about 800 meters, and finally completed the exploration sample. In December 2020, the black sand -shaped substance with a weight of about 5.4 grams was finally taken back. Soon the Japanese research institutions began to analyze these asteroid samples. Soon after these samples, carbon and nitrogen were found in these samples. Essence With the gradual deepening of analysis and research, in June 20022, scientific researchers finally found the amino acid figure in these samples, and once found more than 20 amino acids that are closely related to life activities. Acknowledged.

Finding amino acids in asteroid samples means that the life of the earth is brought by the asteroid?

It is still too early to make such conclusions. First of all, it should be certain that this discovery can indeed be used as a evidence that the credibility of "the early Earth's amino acids are brought by the asteroid" increased. These samples have been on the earth for two years, wouldn't it be polluted? According to the information provided by Japan, the analysis of the "Dragon Palace" sample is performed in a form that is not exposed to external air, so these samples should not be polluted. However, this can only prove that there is amino acids on the celestial bodies outside the earth. Early amino acids on the earth may also be brought by the falling meteorite, but the life of the earth originated from the asteroid, it is exaggerated.

Although amino acid is the basic unit of life, it is still worse than life.

Since the world's first artificial satellite in 1957, the history of human aerospace has been more than 60 years. Why is it now confirming the existence of amino acids on the asteroid? It is mainly that humans have insufficient enthusiasm for the detection of small stars. In fact, Japan has always stared at the moon, but after 17 years of hard work, because many key calculations cannot achieve breakthroughs, they have to be terminated in 2007. And focusing on the asteroid, so this time the asteroid "Dragon Palace" was sampled. Is it easier to explore asteroids than to explore the moon? Yes.

If you want to send the detector into the moon track, you must first have a rocket with strong thrust.

Calculating it, Japan's J -series carrier rockets can only send 1 ton objects into the moon orbit. Even if the detector does not have enough thrust, the detector cannot be achieved safely on the surface of the moon. However, there is no obstacle to exploring the asteroid, and even if you do n’t need to log in, you can sample. The sampling process of No. 2 is simply speaking. bell. So why not spend more time, collect more samples back? The Bird No. 2 returns to the cabin to use the traditional ballistic type to return to the return, so a large amount of thermal insulation material is required, so that the space is compressed, and the capacity of the sample warehouse cannot be too large.
