I'm sadly uninterested in the Sun, but I think, in my amateur way, of
the Sun as a sort of
pressure cooker. I'm thinking that the core of the Sun is providing the heat by fusing away at 15 million K, and the solar convective core is functioning as a sort of "lid"... until something really powerful breaks through and starts prominencing.
The NASA of the Sun is in its darkest depths, were no daylight exists, or so I think anyway. Solar fusion produces helium and gamma rays, not optical light that we could, in theory, see, if we could somehow plunge our heads into the center of the Sun and peek around in there. Better put on some sunscreen as we admire that Sun's NASA fusion engine.
EDIT: I can see that Art just provided the correct scientific explanation. Thanks, Art!
