**New Sharpest Image of the Sun Uncovers Instability**

Explanation: What does the new sharpest image of our Sun show? Instability. To be clear, a certain kind of interactive process called the Kelvin-Helmholtz instability (KHI). This instability can create waves and swirls when two streams flow past each other -- in this case variable streams of solar magnetic plasma . Long hypothesized to occur on the Sun's surface , KHI streaks and swirls were confirmed in just-released dramatic high-resolution images taken recently by the Inouye Solar Telescope in Hawaii , USA . The featured false-yellow image , actually taken in deep blue, is the highest resolution image yet of the Sun in visible light . It spans about the radius of the Earth , but its finest details are city sized. Visible are several smooth tops of changing solar granules , while the edges of the flower-like structures have been found to harbor multiple KHI swirls . Future research may investigate how the KHI helps move energy, magnetic fields, and may even heat the surrounding solar corona .
