TL;DR

Using the Daniel K. Inouye Solar Telescope near Maui, scientists captured the Sun’s visible surface in unprecedented detail, revealing Kelvin-Helmholtz instabilities—tiny swirling vortices along magnetic boundaries—that could explain why the Sun’s outer atmosphere (the corona) is hotter than its surface and how magnetic energy is built, released and transported to drive solar flares and coronal mass ejections. The observations align with advanced simulations and may improve space-weather forecasting that affects satellites and power grids.
