    ?The surface of the Sun has been photographed in more detail than ever
    before, and it turns out to be covered in whirlpools. Victoria Gill
    reports for BBC News on the most detailed images of the Sun yet, taken
    by the Inouye Solar Telescope on a high peak in Hawaii and published in
    the journal Nature.?

    ?The swirls are the Sun's magnetic field being twisted and shoved around
    by the motion of hot gas. Physicists call the effect Kelvin-Helmholtz instability, and it turns up whenever two fluids slide past each other
    and small disturbances grow into spiraling vortices. In the ocean, it is
    what builds ripples into big waves. The National Solar Observatory says
    the vortices on the Sun sit 50 to 65 kilometers apart.?

    That is cool. Definitely looks the part of the Great Ball of Fire.
