Type II Supernovae

Type II supernovae are explosive events marking the death of massive stars, typically more than eight times the mass of our Sun. When these stars exhaust their nuclear fuel, they can no longer support themselves against gravity. The core collapses, causing the outer layers to explode outward with tremendous force. This explosion can outshine an entire galaxy for a short time and spreads heavy elements into space, contributing to the formation of new stars and planets. Type II supernovae are crucial for understanding cosmic evolution and the life cycles of stars.
