Gas giants, like Jupiter, Saturn, or some of the largest exoplanets, are mostly made of Hydrogen gas.  The simplest and most abundant element in the universe, Hydrogen easily reacts to form compounds, especially at higher temperatures, making it hard to contain and work with.  It’s essential to understand how it behaves across a range of temperatures and pressures so that we can understand the interiors of stars and planets.  But there may also be applications closer to home, like the white whale of materials science, a room temperature superconductor. A team of researchers from Osaka University and Tokyo Institute of...
