New way to study how elements mix in giant planets

June 19, 2020- 
There are giants among us — gas and ice giants, to be specific. They orbit the same star, but their environmental conditions and chemical makeup are wildly different from those of Earth. These enormous planets — Jupiter, Saturn, Neptune and Uranus — can be seen as natural laboratories for the physics of matter at extreme temperatures and pressures. Now, an international team including...
