Maybe the only fact about the Sun that may somehow prevent all of it's power to run wild against us is that a **photon** created at the Sun's core (which is the way energy gets to the earth) takes an **average of 170.000 years** to reach the Sun's surface and then leave towards the Earth. They take so much because the photons are absorbed and re-emited constantly by the charged plasma particles.

<p>Does the sun have a protective layer that at least diminishes its radiation. I know the earth's atmosphere protects us from harmful rays. But does the sun have a sort of shield as well that if removed would radiate more heat. </p>

You seriously cannot expect the sun to have a layer that would contain some of its harmful radiation. Sun consists of a plasma and is not solid. Learn more about its structure [here](http://en.wikipedia.org/wiki/Sun). Magnetic field is a kind of layer you might think of apart from all gases and energy it radiates. But that is harmful and not protective for us. It is highly unlike earth which has a solid crust. **Any layer around sun wouldn't actually protect us as it would have to contain a huge amount of energy and that would make it more unstable**.
