Researchers conducted experiments exploring the solubility of silica and water under high pressures and temperatures, simulating conditions that may exist in the interiors of Neptune-like exoplanets; the results suggest mutual solubility between silica and water that may make the boundary between rock and ice fuzzy in such planets, with implications for understanding the geochemistry of water-rich planets, according to the authors.
