The superstar goes through many stages onwards it explodes. In all stars, there is a constant fighting between fusion, which pushes out, and gravity, which pulls in. When the star starts to run out of fuel, fusion slows cut and gravity starts to lure the battle and pulls all of the stars liaison toward the middle. Then, the star collapses on itself and releases a small amount of pent-up energy. This energy is used to shoot out matter at about 9,000 to 25,000 miles per hour (The Science Encyclopedia).

Now, the star turns into a red giant and shin es more brightly than all the stars in our g! alaxy unite (Nave).
