Supercomputer Simulation of Sun’s Magnetic Field Loops
Researchers at NASA and its university partners are using supercomputer to simulate Sun‘s magnetic field loops, to learn how they emerge, heat the sun’s outer atmosphere and produce sunspots and flares.
Magnetic fields emerging from below the surface of the sun influence the solar wind—a stream of particles that blows continuously from the sun’s atmosphere through the solar system.
This visualization shows magnetic field loops in a portion of the sun, with colors representing magnetic field strength from weak (blue) to strong (red). The simulation was run on the Pleiades supercomputer at the NASA Advanced Supercomputing facility at NASA’s Ames Research Center in Moffett Field, California.
The knowledge gained through simulation results like this one help researchers better understand the sun, its variations, and its interactions with Earth and the solar system.
