Scientists discover interstellar clouds or lead to the loss of Mars (video) jiqingwuyuetian

The scientists found that the interstellar cloud or cause loss of the Martian atmosphere these changes with the sun around the Milky Way system operated gradually, the solar system from time to time will pass through interstellar clouds of gas and dust is large, dense, the whole process will continue for 1 million years. Tencent space news according to foreign media reports, recently, scientists found that the solar wind may not only cause the culprit of the thin Martian atmosphere. Once upon a time, Mars had a thick atmosphere, enough to make it liquid. But now the wide ditches, some scientists believe that the coastline of the terrain features, has completely dried up. There must be something that has been weakening the atmosphere of Mars, and there is currently a task on orbit to study when and when this phenomenon occurs and how fast it will weaken. By studying the latest observations of the Mars atmosphere and volatile matter evolution task (MAVEN), scientists have discovered a new source of Mars’s atmosphere that is likely to be lost. Scientists have long known that the solar wind can cause the loss of hydrogen molecules in the Martian atmosphere. The new study shows that interstellar clouds can also have an impact on this. Dimitra, a scientist at the blue marble Space Science Institute, said MAVEN had identified the main cause of the loss of the atmosphere of the atmosphere, the ionizing radiation from the sun, and the Atri. I am currently looking at the geological environment when Mars meets the interstellar cloud. These changes are taking place as the solar system moves around the Milky way, and the system of the sun passes through the interstellar clouds from time to time, which is a large, dense gas and dust that lasts for 1 million years. According to the geological record of the earth, at least 135 times since the formation of the solar system about 4 billion 500 million years ago. Each time through, the clouds of gas and dust will impact the solar wind, forming a bow shock. This shock will accelerate charged particles, causing the Martian atmosphere to lose 0.5%. Because each time is very long, Atri’s calculations show that over time, Mars has lost about half its atmosphere. Other causes of the loss of the atmosphere, such as solar flares or supernova explosions, have little effect on the loss of the Martian atmosphere. Atri said that even when the solar flare is most intense, it is 6 orders of magnitude smaller than the atmosphere lost through interstellar clouds. The study could also be extended to the study of other planets in the atmosphere. If a planet has a strong magnetic field, the particles will not be able to penetrate the atmosphere, thus preserving the atmosphere better. Atri hopes to further investigate the effects of historical solar activity and how it affects the Martian atmosphere. There are a lot of sand dunes on Mars, which is caused by a lot of material deposited by the wind, forming some of the most beautiful sand dunes on all the planets in our solar system. By using the high resolution imaging experiment NASA installed in the Mars Reconnaissance Orbiter (HiRISE), planetary scientists to view these observations in orbit and landform characteristics, is helpful for us to further understand the aeolian processes and geology of mars.
