Electrical conductivities of hydrogen were measured recently at 93–180 GPa (0.93–1.8 Mbar), 0.28–0.36 mol cm −3 , and 2000–4000 K. Shock temperatures were measured up to values of 5200 K at 0.83 Mbar. The conductivities indicate a continuous transition from a semiconducting to metallic fluid at 140 GPa and 3000 K. The results indicate that hydrogen becomes metallic much closer to the surface of Jupiter than thought previously and that Jupiter has no core–mantle boundary.
