answer:
a supernova happens and it's quite a beautiful thing. a supernova happens when a star runs out of fuel (hydrogen) and once there isn't any fuel left the star begins to collapse and the outer layer explodes into a supernova. cool right? ( now not all stars explode into supernovas just the red giants. some other stars just fade away.)
