Why Does The Sun Keep on Shining???

Answer 1

Good question, but since it's pretty much already been answered, I won't actually answer, but instead just comment.  Sometimes I wish it didn't shine, but at the same time, if it didn't, then weather as we know it wouldn't exist.  So I guess it's necessary. :)

Answer 2

It's a continuous thermonuclear reaction, and it emits energy of many different wavelengths, including the visible light that humans call :"shining".

Answer 3

The sun is a giant mass of of hydrogen (about 74% of its mass, or 92% of its volume), helium (about 24-25% of mass,[10] 7% of volume), and trace quantities of other elements, including Fe, Ni, O, Si, S, Mg, C, Ne, Ca, and Cr.[11] The Sun has a spectral class of G2V. G2 means that it has a surface temperature of approximately 5,780 K, giving it a white color which, because of atmospheric scattering, appears yellow as seen from the surface of the Earth.  Thus this is why it gives off so much energy. The sun is also to be considered as a Star.
