Genesis for Exploding Stars Confirmed
Before and after images reveal that red supergiant stars are responsible for Type II supernovas.
Type II supernovas are the impressive cosmic explosions that result from the internal collapse of a massive star. (For this reason, they are also known as core-collapse supernovas.)
