Nothing lives forever, not even the stars. Our Sun, like all true stars, thrives on nuclear fusion in its core. At millions of degrees, it converts hydrogen into helium, and will later heat up further, fusing helium into carbon. Like most stars, it will never get hot enough to go supernova. When it runs out of fuel, it will contract into a white dwarf, blowing off its outer layers, forming a planetary nebula.
