New Sharpest Image of the Sun Uncovers Instability
NASA
- The Inouye Solar Telescope in Hawaii has captured the sharpest-ever image of the Sun, confirming the presence of Kelvin-Helmholtz instability (KHI).
- KHI is a process that creates waves and swirls when two streams of solar magnetic plasma flow past one another at different speeds.
Key Findings
- KHI streaks and swirls were identified along the edges of flower-like solar granules.
- While the image covers an area roughly the size of Earth's radius, the resolution is detailed enough to distinguish city-sized features.
- The image was taken in deep blue light and rendered in false-yellow to emphasize solar details.
Scientific Implications
- The discovery helps explain how magnetic fields and energy move across the solar surface.
- Future research will investigate whether KHI contributes to the heating of the surrounding solar corona.
