Unique images may solve solar mystery
Unprecedented high-resolution images of the sun’s surface captured by the Inouye solar telescope have revealed signatures of Kelvin-Helmholtz instabilities, small whirlpool-like structures that may explain why the sun’s corona is millions of degrees hotter than its surface. These observations, the most detailed ever taken, show features smaller than 20 km and suggest that such instabilities could dissipate energy as heat, potentially solving a long-standing mystery in solar physics. The findings provide new insights into solar magnetic activity and the processes that heat the sun’s outer atmosphere.
