Is the sun able to produce gamma ray light?

Yes is is. The only “problem” (it's actually a good thing for living beings on Earth) is that all the nefast radiation, gamma rays included, are blocked out by either the magnetic field of the planet, or by the atmosphere itself. read more

The Sun produces gamma rays all the time in its core. But these collide so often with hydrogen atoms, they get split into much lower energy photons by the time they reach the surface where we see lots of visible light, peaked in the yellow. read more

The Sun does, however, emit X-rays, ultraviolet, visible light, infrared, and even radio waves not to mention neutrinos. Gamma ray photons produced by fission make their arduous journey to the surface of the Sun, they are continuously absorbed by the solar plasma and re-emitted to lower frequencies. read more

Instead, the sun’s gamma ray emissions are produced by processes near the surface, with solar flares being by far the most important source. Since solar activity is so variable, the level of gamma rays we receive from the sun changes greatly, even from one day to the next. read more

Actually, the Sun does not only produce IR, visible light, and UV. Fusion in the core actually gives off high energy gamma rays. However, as the gamma ray photons make their arduous journey to the surface of the Sun, they are continuously absorbed by the solar plasma and re-emitted to lower frequencies. read more
