What are these 'whirlpools'?

The story mentions 'whirlpools' on the Sun's surface, which scientists call Kelvin-Helmholtz instabilities. These are like swirling eddies you might see in water or clouds, but on a cosmic scale. They happen when hot gases in the Sun's atmosphere move past each other at different speeds, creating these twisting, unstable motions.
