In the study, hcp ice became dominant above 200 gigapascals (GPa) and 1,800 kelvins (K) in the superionic regime. The result adds a possible phase for models of Uranus and Neptune to consider; it does not show that either planet contains a particular amount of this ice.
What the researchers observed
The study reports hcp water ice in the hot, dense conditions associated with superionic ice. Here, “hexagonal close-packed” describes how oxygen atoms are arranged in a crystal lattice. It does not mean ordinary freezer ice has been compressed into a different-looking cube.

In superionic ice, the oxygen framework remains ordered while hydrogen moves through it. The paper’s abstract places the hcp observation in this regime, but does not by itself establish detailed electrical or mechanical properties of the hcp form.

How scientists made and identified the ice
The team compressed and laser-heated a small water sample in diamond anvil cells, then used synchrotron X-ray diffraction to infer its structure from the resulting diffraction patterns. This is a controlled laboratory experiment, not a sample taken from a planet.
Diffraction allows researchers to distinguish atomic arrangements by the patterns produced when X-rays interact with a crystal. The study reports observations of oxygen lattices described as body-centered cubic (bcc), face-centered cubic (fcc), and hcp; these labels refer to different ways atoms are packed, not to different planetary ingredients.

How the reported structures relate
| Structure or transition | What the study reports |
|---|---|
| Hcp | Becomes dominant above 200 GPa and 1,800 K in the superionic regime, according to the APS abstract. |
| Fcc to hcp | The authors say observations are consistent with hcp becoming thermodynamically more stable than fcc through a martensitic transition across 130–200 GPa. |
| Cooling-related change | The authors report hcp emerging from stacking disorder in the fcc oxygen lattice as the material cools and reverts toward the bcc phase. |
The pressure interval and cooling pathway describe the authors’ interpretation of the experimental observations; they should not be read as a complete map of ice’s stability under every condition.
What this could mean for Uranus and Neptune
The result gives planetary scientists another possible water-ice structure to account for when modeling the interiors of the ice giants. The paper’s abstract says the fcc-hcp transition in superionic warm dense ice may have implications for those models.

- These unique molecular structures are excellent for visual display
The experiment does not directly measure conditions inside Uranus or Neptune, determine whether either planet contains hcp ice, or establish the proportion of any such phase. It also does not settle the planets’ broader composition. A laboratory observation can inform models without proving that a specific phase occurs in a specific planet.

- Established in the report: an hcp oxygen-lattice structure was observed in water ice under extreme laboratory pressure and temperature, using synchrotron X-ray diffraction.
- Authors’ interpretation: hcp becomes dominant above 200 GPa and 1,800 K in the superionic regime, and observations are consistent with fcc-hcp transition behavior across 130–200 GPa.
- Not established by this result: the amount or distribution of hcp ice inside either ice giant, or the planets’ full interior composition.
