The origin of rings is one of the final arguments in a series explaining solar system formation. Liquid moons placed in circular orbits close to the planet (inside the Roche limit) will deposit ring material as they m...

Understanding the internal composition of a celestial body is fundamental for formulating theories regarding its origin.Deep knowledge of the distribution of mass under the body’s crust can be achieved by analyzing i...
Chang’e-4 is the first man-made probe that accomplished landing and roving on the far side of the Moon,which is viewed as a new milestone in the history of Lunar exploration.Beginning with a brief introduction to the...

Jupiter is one of the major targets for planetary exploration,and dust in the Jovian system is of great interest to researchers in the field of planetary science.In this paper,we review the five dust populations outsi...
China’s Chang’e-4 probe touched down on the far side of the moon on January 3,the first spacecraft soft-landing on the moon’s uncharted side never visible from Earth.The probe,comprising a lander and a rover,landed...

To better understand Earth's present tectonic style-plate tectonics—and how it may have evolved from single plate(stagnant lid) tectonics, it is instructive to consider how common it is among similar bodies in the So...
