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

The U.S. National Science Foundation propels the nation forward by advancing fundamental research in all fields of science and engineering. NSF supports research and people by providing facilities, instruments and funding to support their ingenuity and sustain the U.S. as a global leader in research and innovation. With a fiscal year 2023 budget of $9.5 billion, NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and institutions. Each year, NSF receives more than 40,000 competitive proposals and makes about 11,000 new awards. Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts.
