The Sun Is Not On Fire.

​The sun is not on fire. There is no oxygen in space and fire—or combustion--requires oxygen. The sun does not burn, it fuses. The sun’s glow is from nuclear fusion taking place at its core. Every second the sun converts 700 million tons of hydrogen into 695 million tons of helium. And those flares that look like flames shooting off the surface of the sun? They are powerful bursts of radiation created by solar quakes and eruptions. All that violent action makes a lot of sound waves. All that heat makes the sound waves move super fast. The waves smash into one another vibrating the sun like a guitar string. The sun is 100 times louder than a rock concert. It’s a good thing sound can’t travel through space, or we wouldn’t be able to hear anything else. What? What did you say? I can’t hear you over the noisy sun!
