The sun is a big ball of gas and plasma. Most of the gas â 91 percent â is hydrogen. It is converted into energy in the sun's core. The energy moves outward through the interior layers, into the sun's atmosphere, and is released into the solar system as heat and light. Nuclear fusion. In the sun's core, gravitational forces create tremendous pressure and temperatures. The temperature of the sun in this layer is about 27 million degrees Fahrenheit (15 million degrees Celsius). Hydrogen atoms are compressed and fuse together, creating helium. This process is called nuclear fusion. As the gases heat up, atoms break apart into charged particles, turning the gas into plasma.
So, the sun gives off light because of the different types of gases in the core. These gases , when combined, create radiation. The sun gives off this radiation in rays, produâ¦cing light rays, that comes from our sun and other stars. -This all comes from a 8th grader. Additional answer The Sun is very very hot and hot objects, as you know by a red hot poker, emit light and heat.
