Scientists have discovered that Mercury has frequent crustal activity (video)-kd.wuhan.net.cn

The scientists found that Mercury has crustal activity in the lunar surface there are some frequently due to the shrinkage of the fault scarp, the fault scarp is not age, size is very close to the surface of small fault scarp newly discovered mercury. Tencent space news, according to foreign media reports, NASA’s MESSENGER spacecraft mercury surface photos show that the surface of mercury is likely to continue to shrink. This makes Mercury the planet in the solar system, another planet with active geological activity. According to the published in "natural science" on earth · the latest paper in the last 18 months messenger orbiting mercury tasks, there are some small faults not previously observed scarp messenger in the photo shoot. Because the messenger has lowered its orbit in the last few months, it has captured the surface of mercury with unprecedented clarity. The Planetary Science Institute researcher Maria Banks is the author of the article "Deputy revealed by small fault scarp in recent mercury geological activities", the main author of the article is the Smith Institute senior scientist Thomas R. Watters. Watters is also the main person in charge of the research project. Banks studied the messenger’s return. In these photographs, he found and analyzed the structure of the small-scale geological activity. He said that these small reverse fault scarp is very small, only a few kilometers in length. Much smaller than similar structures that have previously been found on the surface of mercury. These structures are only recently generated due to the continued destruction of this small structure by an asteroid collision. The surface of the moon is also due to the contraction of the moon’s fault scarp, these fault scarp age is not large, very close to the size of the newly discovered mercury surface small fault scarp. A fault scarp is a cliff like terrain. There was a large, old fault scarp in the photos sent back by the messenger probe and the early mariner probe. This is evidence of the contraction of the earth’s crust due to internal cooling. The United States National Aeronautics and space museum under the center of earth and planetary research Watters said that these scarps are not very old, means that the mercury in the solar system has become another earth like planet, with active geological activities. Since mercury is still cool inside, the surface is likely to generate new fault scarp. In addition to the active fault, Johnson, a senior scientist at the Planetary Science Institute, recently discovered that Mercury had its own magnetic field billions of years ago. Catherine. The outer core of mercury is still at a high temperature, but the two findings show that it has been cooling slowly for a long time. Appollo mission was deployed on the surface of the moon seismograph. These seismographs detected a shallow earthquake on the surface of the moon, the magnitude of which could even reach 5 on the Richter scale. These shallow earthquakes may be related to the fault scarp slope connected to the small steep slope on the moon. In the future mission, we will deploy a seismograph on the surface of mercury, and we may be able to monitor the trace of mercury. Why is there no atmosphere on mercury?相关的主题文章:
