For twenty years, the fate of diamond under the crushing pressures of ice giant planets remained one of science's quiet mysteries. Now, in a terrestrial laboratory, researchers have finally witnessed it: diamond, subjected to one trillion pascals of pressure, melts. The experiment does not merely answer a planetary science question — it opens a corridor between the deep interiors of Neptune and Uranus and the engineering challenges of fusion energy, reminding us that the most distant corners of the cosmos often hold the keys to our most urgent earthly ambitions.
