Tiny Plasma Whirlpools Found on Sun Could Spark Nanoflares Today Scientists spot 20‑kilometer‑wide vortices on the Sun that may twist magnetic fields and trigger tiny solar eruptions. Using high‑resolution imaging from the Solar Dynamics Observatory, researchers recorded swirling plasma patterns as small as 20 kilometers across.

These vortices, invisible until now, appear to tangle magnetic fields, potentially fueling nanoflares—tiny but frequent solar explosions that heat the Sun’s outer atmosphere. The study, published in the Astrophysical Journal, suggests the whirlpools could accelerate magnetic diffusion, explaining why the solar corona warms faster than models predict.

However, the observations are limited to a few days of data and rely on indirect temperature measurements, so more long‑term studies are needed to confirm the mechanism. If these micro‑whirlpools truly drive coronal heating, they might also influence space weather that affects Earth’s satellites.

Could the Sun’s hidden turbulence hold the key to predicting solar storms? 🧪
