Because the spectrometer says so, mainly. Why?

The nuclear reactions occurring within the sun emit a wide spectrum of radiation, everything from sub-visible thermal radiation to high energy gamma rays. Thankfully, the Earth’s own electromagnetic field and ozone protects us from all but a tiny sliver of ionizing radiation or we wouldn’t be here to talk about it.

Isn’t most of that radiation blocked by the outer layers of the sun, though? Like, sure, there is a non-negligible amount of high energy photons escaping, but the overwhelming majority of the radiation comes AFAIK from blackbody radiation from the plasma at the temperature of the surface of the sun?
