Our University's academic research team found that the moon is warm inside


   Recently, our school the planetary science institute postdoctoral original Dr Tian Xiongsi, joint, wuhan university, national astronomical observatory researchers and scholars in Japan and the United States, published in the latest issue of "team" research paper "Strong tidal heating in an ultralow - viscosity zone at the core, mantle boundary of the Moon. In the study, the method of using digital simulation, lunar nuclear curtain found a layer boundary of the area of low viscosity. The results and predecessors for lunar geodetic observations, prove the existence of the nuclear curtain boundary by months to partial melting caused by tidal action. The study is to rediscover the thermal state and thermal history of the moon is of great significance.

   Because the moon is small in size, the scientific community generally believe that the moon in basic stopped geologic activity 2 billion years ago, the moon is now a big stones, lack of geological activity. However, the team used, including "chang 'e 1" lunar data, on the shape changes of the dynamics of the moon precision measurement, and with the aid of theoretical analysis and calculation, found in the nucleus of the moon - there is a low viscosity mantle boundary weak layer. And the earth's gravity has been on the weak layer with strong tidal heating process. This outcome to rethink and know the internal structure, the thermal evolution, as well as the interaction of the month system puts forward a new topic.

   The original Tian Xiongsi doctoral tutor professor XiaoLong think of cooperation, the results for us to know the moon and the terrestrial planet's internal structure, thermal state and thermal history has important significance. The planetary science institute researchers in our school will be further from the deformation characteristics, internal to the lunar surface gravity field and the structural and physical properties, and other aspects, further studies on the moon.
