Uncovering the mystery of a solid hydrogen phase that was unexpected

Scientists Discover an Odd New Phase of Hydrogen

The new solid hydrogen phase, discovered by a team of international researchers, followed the model’s presentation of hydrogen atoms under extreme conditions. To use an analogy with food: their shape changed from spheres that looked like oranges stacked on top of each other to something more closely similar to eggs.

In order for hydrogen to solidify, it usually requires extremely low temperatures and high pressures. The scientists discovered the molecular structure through a machine-learning study of the phase change.
