Daniel K. Inouye Solar Telescope captures first Kelvin‑Helmholtz instability on Sun

Scientists using the Daniel K. Inouye Solar Telescope (DKIST) on Haleakalā volcano, Maui, obtained the highest‑resolution images ever of the Sun’s photosphere. The observations, published in Nature on 5 August 2026, reveal tiny vortex structures—ranging from about 20 km to 65 km across—identified as Kelvin‑Helmholtz instabilities, a fluid‑dynamic phenomenon previously only theorised for the solar surface. The international team, including David Kuridze and Friedrich Wöger of the U.S. National Solar Observatory, confirmed these instabilities for the first time on a star.

The discovery provides new insight into how plasma motions transport magnetic energy, potentially explaining why the solar corona is far hotter than the photosphere and how energy is stored for solar flares and coronal‑mass ejections. Those eruptions can disrupt satellites, GPS, power grids and communications on Earth, making the findings relevant to space‑weather forecasting and fundamental solar physics.
