All planets are made of gas, ice, rock and metal, and models of how planets form usually assume that these materials don't ...

So researchers designed an experiment to compress hydrogen and helium, reaching pressures nearly 2 million times Earth’s atmospheric ... which becomes a liquid metal under these conditions ...

Unlike Earth and other rocky planets ... Deep within Jupiter, the extreme pressure compresses hydrogen gas into a liquid state, creating an ocean of liquid metallic hydrogen.

Hydrogen energy is widely ... these nanosheets using palladium metal." The team developed PdDI nanosheets (C-PdDI and E-PdDI) using two different methods: gas-liquid interfacial synthesis and ...
