Helium, known for its chemical inertness ... researchers have demonstrated that it can integrate into the crystalline structure of iron under extreme conditions of pressure and temperature.

While this is less than the pressure in the core (about 350 GPa), the reactions created molecular lattices of iron and helium. These structures remained ... also revealed a dynamically stable crystal ...

Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...
