Giant Super-Earths Made of Diamond Are Possible, Study suggests

A new study suggests that some stars in the Milky Wy could harbor "carbon super-Earths" that contain up to 50 percent diamonds. These planets are likely devoid of life, that is, if they even exist. The study took place at Ohio State University where researchers recreated the temperatures and pressures of Earth's lower mantle to study how diamonds form there. The main goal was to comprehend what happens to carbon inside planets in other solar systems, and whether solar systems that are rich in carbon could produce planets that are mostly made of diamond. The result of the study concluded that it was possible for planets that are as big as fifteen times the mass of the Earth to be half made of diamond. It is believed that a diamond planet must be a very dark and cold place with no geothermal energy, no plate tectonics and ultimately no magnetic field or atmosphere.

It's fascinating to hear this.. I never realized that planets could possibly be made entirely of minerals like diamonds! I wonder if we can get any more information about other planets like this in the future. After all, could there be a planet almost entirely composed of gold, silver, or quartz? I'm just fascinated by all the possibilities of planet composition.
