Why are supernovas important in the universe?

Supernovas are important because they help make and spread the heavy elements needed for life and planets. When they explode, supernovas scatter elements like iron, carbon, and oxygen into space, which later become parts of new stars, planets, and living organisms. Supernovas also help scientists study how stars evolve and die. Their shockwaves can trigger the birth of new stars by compressing clouds of gas. Overall, supernovas play a major role in shaping the universe and creating the building blocks of everything we see.
