TL;DR

Researchers using the 4‑meter Daniel K. Inouye Solar Telescope imaged Kelvin‑Helmholtz vortexes at 416 nm on the Sun’s surface, showing 60–100 km spacing and 25–170 km-diameter structures that can grow quickly and travel 0.67–3 km/s. The observations, aided by high-speed imaging and advanced deconvolution, suggest a new mechanism for heat, mass, and magnetic-energy transport in the solar atmosphere and may affect convection and corona heating models. The study combines telescope data with simulations to confirm the effect, but is based on a short (about 3 minutes) observation window and calls for longer, magnetic-field–map measurements to fully quantify energy budgets.
