Does the Sun emit X-rays?

The X-rays we detect from the Sun do not come from the Sun's surface, but from the solar corona, which is the upper layer of the Sun's atmosphere. Only very hot gases can emit X-rays, and the corona, at millions of degrees, is hot enough to emit X-rays, while the much cooler surface of the Sun is not. read more

The X-rays we detect from the Sun do not come from the Sun's surface, but from the solar corona, which is the upper layer of the Sun's atmosphere. Only very hot gases can emit X-rays, and the corona, at millions of degrees, is hot enough to emit X-rays, while the much cooler surface of the Sun is not. Thus, the Sun's atmosphere is an excellent source of X-rays. read more

Yes the sun does give off X-Rays. It gives off every part of the EM spectrum except for gamma rays. Though the sun doesn't give off as much X-Rays as it would give off other forms of light considering X-Rays require a lot more energy to be produced naturally. The sun even gives off some radio waves too. 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
