When Jupiter formed 4.5 billion years ago, rocks and ice combined to form a rocky core 14-18 times the mass of the Earth, according to a new simulation by University of California, Berkeley geophysicist Burkhard Militzer. This is twice what previous models predicted. Militzer employed a simulation technique designed to model the properties of semiconductors and now used for nanomaterials. This simulation also predicts fewer areas of ice throughout the rest of the atmosphere. Full Story
