The outer asteroid outside the solar system may bring organic matter and water to the earth

Xinhua News Agency, Tokyo, August 18th. Researchers in Japan and other countries have recently published papers in the British "Nature · Astronomy" magazine that small asteroids outside the solar system may bring organic matter and water for the earth for the earth.

According to the "Yomiuri News" recently reported, the asteroid "Dragon Palace" is now mainly located between the earth and Mars that are closer to the solar. The previous research on the "Dragon Palace" sample found that it contains water and organic matter.

Researchers from Japan's Marine Research and Development Agency and other institutions analyzed the "Dragon Palace" samples and found that the characteristics of hydrogen and nitrogen are very similar to the dust outside the universe outside the sea king star. They speculated that the mother of the "Dragon Palace" was located outside the solar system. After moving and dividing, the "Dragon Palace" came to the current track.

Researchers use electronic microscope and other means to observe samples that there are a large number of organic matter inside the water -containing clay minerals. The types of organic matter are unknown, but it may contain amino acids and sugar. Researchers believe that organic matter and water are not heat -resistant and impact, and clay minerals have played a "cradle" role. Under its protection, the materials formed by organic matter and water may be taken near the earth.

Researchers have speculated that asteroids may bring organic matter and water to the earth. The research of small asteroids helps understand the birth process of the earth's life and the formation of the solar system.

In early June, Japanese researchers found more than 20 amino acids in the rock samples of the "Dragon Palace". These amino acids may be related to the birth of the earth.

The Japanese asteroid detector "Bird 2" was launched in 2014. In June 2018, I arrived near the asteroid "Dragon Palace" and collected samples of asteroid rocks. Essence Bird No. 2 probe continues space journey after being separated from the recycling cabin.
