Researchers awarded 83 million hours of supercomputer time

Led by UCLA geophysics professor Jonathan Aurnou, the team will use the Mira supercomputer at Argonne National Laboratory to simulate the generation of the Earth’s magnetic field, using Rayleigh Code, computer software designed for this specific purpose at the Computational Infrastructure for Geodynamics (CIG) at UC Davis. The researchers will also simulate the magnetic field generation occurring inside Jupiter and the Sun.

Masongsong explains the Planeterrella, a miniature Earth model that can simulate the aurora (Northern Lights) and other plasma phenomena, the sight of which causes "children and adults to shriek with delight, 'ooh-ing' and 'aah-ing' at the eerie glow of plasma suspended in a ring before their very eyes.

Greetings from the Chairman


In the Department of Earth, Planetary, and Space Sciences, we seek to understand the Earth and the planets. Our students, researchers, and faculty tackle a wide range of problems, from the Sun to the most distant planets, and from the center of the Earth to the tenuous ionized gases of the solar wind. We probe the interior of the Earth using seismic data, laboratory measurements, and computer modeling. We study both the ancient tectonics of the Earth and its ongoing activity. We explore Earth's upper atmosphere using spacecraft to measure magnetic fields and plasmas. Moving outward from Earth, we study other planets, their interiors, surfaces, atmospheres, and particle and field environments.
