APOD: 2026 August 6 Б New Sharpest Image of the Sun Uncovers Instability
6.08.2026

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.
