Solar Dynamics Observatory (SDO)

A 3D simulation showing the evolution of turbulent flows in the upper layers of the Sun. The more saturated and bright reds represent the most vigorous upward or downward twisting motions. Clear areas represent areas where there are only relatively slow up-flows, with very little twisting. NASA/Irina Kitiashvili and Timothy A. Sandstrom

Ready, Set, Action! Our Sun is the Star in Dazzling Simulation

NASA supercomputers are shedding light on what causes some of the Sun’s most complex behaviors. Using data from the suite of active Sun-watching spacecraft currently observing the star at the heart of our solar system, researchers can explore solar dynamics like never before. 

The animation shows the strength of the turbulent motions of the Sun’s inner layers as materials twist into its atmosphere, resembling a roiling pot of boiling water or a flurry of schooling fish sending material bubbling up to the surface or diving it further down below. 

“Our simulations use what we call a realistic approach, which means we include as much as we know to-date about solar plasma to reproduce different phenomena observed with NASA space missions,” said Irina Kitiashvili, a scientist at NASA’s Ames Research Center in California’s Silicon Valley who helped lead the study. 

Using modern computational capabilities, the team was able for the first time to reproduce the fine structures of the subsurface layer observed with NASA’s Solar Dynamics Observatory…
