According to the report of China Journal on August 13, a new study by NASA shows that the shiny salt layer on Ceres' surface is left by its underground seepage water, and there may be a huge ocean deep underground, and there may have been alien life or suitable life.

Water is the source of life, and it is the same for any living body. But are there other water resources in the solar system besides the earth, or can they become? The second earth? What about celestial bodies? It is this question that makes scientists discover the marine resources under Ceres.

As a result of the detection, scientists believe that there is a lot of liquid water under the surface of Ceres. ? Dawn? The probe flew around Ceres from 20 15 until the fuel was exhausted. At the end of the flight, dawn? The probe is only 35 kilometers from the surface of Ceres. The main observation point of the detector is the 20-million-year-old Occator crater, where the detector found bright brine deposits from the interior of the planet.

In a paper published in Nature-Astronomy, the researchers analyzed? Dawn? The returned data shows that there is a large brine reservoir deep in the bottom of Okada crater. They believe that the reservoir may have been moved by the forces that caused the formation of craters, which led to these bright salt deposits on the planet's surface. In another paper, it is reported that there is hydrated chlorine salt in the center of the largest bright area in the center of Okato crater. Because of the rapid dehydration of these salts, the author thinks that these brines may still be spewing out, which means that there may still be salty liquid inside Ceres. (The picture shows the theoretical path of water molecules on Ceres drawn by scientists. )

Dawn? The probe also made a dive in the last stage of its career, and made all-round high-magnification data observation on Ceres. Scientists used a spectrometer to find ice salt on Ceres.

In the final flight stage when the fuel was exhausted, the probe was only 22 miles away from the surface of Ceres, and found the saline water reservoir inside Ceres, which was 25 miles deep and extended for hundreds of miles. Although salt water may be an extreme living environment, life on earth originated from primitive oceans, so there may be more such salt water reservoirs in other parts of this dwarf planet, which increases the hope that Ceres may be a livable planet. ?

Ceres has an active frozen hydrological phenomenon. In a paper published in Nature-Earth Science, scientists suggested that the hills of Okato crater may have been formed when the impact caused the flowing water to freeze. This shows that Ceres has recently experienced an active frozen hydrological phenomenon in geology.

In two papers published in Nature-Communication, it is found that the mud samples rich in water and salt on Ceres hit lava in a different way from that on Mars, and the scale is not as large as that on Mars. The bright sediments in Okado crater may have different sources.
