Our Sun's swirling flow This NASA supercomputer simulation shows the strength of the turbulent motions of the Sun’s inner layers as materials twist into its atmosphere. 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. The data-driven animation helps scientists better understand the Sun and what phenomena drive the patterns of its activity. Learn
