  • Juno radio occultations precisely redefine Jupiter’s shape, measuring a polar diameter of 66,842 km and an equatorial diameter of 71,488 km, both smaller than long-used values, bringing models of the planet’s interior into better agreement with observations.

  • Oxygen crystallizes into a sequence of structures, starting as an insulator at low pressure and becoming a superconductor at high pressure. The elusive structure of an intermediate phase has now been determined.

  • At high pressures, water and ammonia are known to exhibit superionic states. Here it is shown that many planetary ices (H-C-N-O compounds) exhibit a superionic state, and in some cases, a doubly superionic state, in which multiple elements diffuse simultaneously.

  • With the discovery of large rocky exoplanets called Super-Earths, questions have arisen regarding the properties of their interiors and their ability to produce a magnetic field. Here, the authors show that under high pressure, molten silicates are semi-metallic and that magma oceans would host a dynamo process.
