Scientists Create Hexagonal Packed Ice at Extreme Pressures
One of the resulting questions is what ice giants like Neptune and Uranus in Earth’s solar system have exactly at their core. We do know that it is mostly rocks and ice, but what kind of ice you end up with at these intense pressures is a good question that [Alexis Forestier] et al. set out to answer, with their results published in a Physical Review Letter paper (ArXiv preprint). It’s noteworthy that there isn’t just water ice at these planetary cores, with this study only investigating water ice specifically.

Scientists Create Hexagonal Packed Ice At Extreme Pressures 1 Comment by: Maya Posch October 6, 2026 Title: Copy Short Link: Copy One of the problems with planetary science is that you generally cannot easily investigate the exact conditions in their interior, so you’re left to extrapolate what is happening inside them based on surface scans. One of the resulting questions is what ice giants like Neptune and Uranus in Earth’s solar system have exactly at their core. We do know that it is mostly rocks and ice, but what kind of ice you end up with at these intense pressures is a good question that [Alexis Forestier] et al. set out to answer, with their results published in a Physical Review Letter paper (ArXiv preprint).
