When a star blows up there is a lot of heat because it is in this pre-explosion stage for millions of years. When the gasses come together they get pulled closer and closer and begin to bang into each other.
A Star's Life CycleBy: Anya Kahriger
Star Star blew up and that's how mommy star and daddy star said I was born.
When stars get old enough their cores start to fill with iron and that is what kills them. Along with this, the two sides of the stars pull apart and this makes them explode into a black hole if they are big enough.
When stars blow up in the Solar system this gives other stars the opportunity to form from either dust and gasses
Star Star got too big and exploded. The gasses and dust from Star Star were brought closer and closer because of gravity
All this gravity comes together and bangs hydrogen and helium together making heat and then creating me, Super Star.
Over thousands of years my two sides started to pull away from each other while the iron is forming in my core
BOOM!!!!!!! Super Star turns into a Supernova and explodes all over the universe!!!!!!
