Better understanding
of planet insides


Researchers at Lawrence Livermore National Laboratory used high-powered lasers to put molten magnesium silicate under extreme pressure. They found out that that it goes through a liquid state phase change by suddenly becoming a denser liquid as pressure increases.

It is thought that the research will give improve the understanding of planet formation because such phase changes have never been considered in planetary evolution models. The critical point about planetary evolution models is that all of the current models are probably wrong because they are based on inaccurate models of how materials change under extreme pressure.

It also suggests that so called supper Earths could have significantly different internal structures from that of the Earth. The result of is that these called supper Earths could be significantly denser than previously thought. Meaning that they would be smaller in diameter, giving them a higher surface gravity making them even less hospitable to life,
