A new study led by Carnegie University's Yingwei Fei aims to understand the inner
Despite the fact that observations of the composition of the exoplanet's atmosphere will becomethe first way to look for signs of life beyond Earth, however, many aspects of the habitability of the planet's surface depend onwhat's going on inside.

On Earth, internal dynamics and structureThe silicate mantle governs plate tectonics and generates geodynamics that feeds our magnetic field and protects us from dangerous ionizing particles and cosmic rays. The life that we see it, would be impossible without this protection. Likewise, the inner dynamics and structure of the super-earths will shape the planet's surface conditions.
Knowing what is happening below the surfacesuper-earth, it is important to study the supposed life on it. But the extreme conditions of the planet's interior do not make it possible to study the features of this celestial body using technology.
In order to build models thatTo understand the internal dynamics and structure of super-Earths, one must have access to samples and conditions similar to the planet being studied. However, it is not always possible to reproduce this in the laboratory. In this case, only heavy-duty equipment can help.
Scientists used the world's most powerfula pulse-energy machine: it provided density and melting point measurements. This is necessary to interpret the observed masses and radii of super-earths.
Researchers have found that under pressure,Characteristic of the subsurface of a super-Earth, bridgmanite has a very high melting point. From this, scientists concluded that rocky planets may have thermally driven geodynamics during the initial phase of their evolution, and then disappear for billions of years as cooling slows.
Sustainable geodynamics can be resumed by the movement of lighter elements through the internal crystallization of the core.
