(LDO)- In the search for models of potentially habitable planets to prepare for future space explorations, a team of scientists realized that the universe could be full of “eggshell planets”. “.
According to an international team of scientists led by NASA, rocky planets that are old and far enough away from their parent stars will have lithospheres as hard and dense as Earth’s lithosphere, while worlds close to their parent stars and young. could be eggshell planets with lithospheres only a few kilometers thick.Dr. Paul Bryrne, a planetary geologist with Carolina State University and Washington University in St. Louis (USA), one of the lead members of the study, said that the structure of the lithosphere will help us predict whether it is capable of forming mountains and possessing a dynamic geological process like Earth’s. Land or not.
So they built a series of planetary models based on known rocky planets and determined the possibility of countless eggshell planets, according to Sci-News.
The eggshell planet will have a shell identical to some of the lowlands on Venus. They may also possess the right conditions for temperature or be in the habitable zone of their parent star, but would be the kind of planet that astronomers should ignore, because the fragile lithosphere would hardly lead to the passage of time. The long-term plate tectonic process cannot help form hills or other complex landforms.
On Earth, it is plate tectonics and other geological activities that help their planet stabilize its atmosphere and climate and stimulate life to multiply and evolve.
Plate tectonics can be understood as the movement of pieces of the Earth’s crust. Currently, the Earth has at least 15 moving pieces, which once made the world appear supercontinent and then split into many continents like today.
The study has just been published in the Journal of Geophysical Research: Planets.
