Why does the sun shine?


Almost all the light given off by the Sun comes from the photosphere, or visible surface. Actually, the Sun doesn't have a real "surface" because it's a ball of very hot gas. The layer of the Sun that emits visible light is the one we see as the solar surface. Most of this light is at visible wavelengths, but higher regions of the Sun's atmosphere give off light ranging from X-rays through to radio wavelengths.

Why does the sun shine?

Like other stars, the Sun is made up mainly of hydrogen gas. The temperature at the Sun's surface is about 10,000 degrees F, but rises to about 27,000,000 degrees F at its core. The temperature and pressure...more
