... Radiative Zone: The radiative zone extends beyond the Sun's core layer, for about another 55% of the Sun's radius. Energy from the nuclear fusion reactions in the core is carried through the plasma of the radiative zone by the sequential absorption and reemission of photons, or energy packets, by ga ...

... The photosphere is a bright layer of the Sun where sunspots form. Sunspots are dark only because they are cooler than the surrounding gases by about 1500 degrees! If you could somehow remove a sunspot and hold it away from the sun, it would glow! Sunspots are huge and can form in groups that are ev ...
