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

If the Sun were to explode, the Earth and the rest of the solar system would be obliterated in an instant. The explosion would unleash an immense burst of light, heat, and radiation, followed by a powerful shockwave that would rip through space. Any remaining core could collapse into a neutron star or even a black hole. But here’s the reality: the Sun isn’t massive enough to explode.
