Supernova Remnant: Cooking Elements In The LMC

Massive stars create elements through nuclear fusion in their cores, starting with hydrogen and helium and progressing to heavier elements like iron. When they die, they explode as supernovae, scattering these elements into space. This material then contributes to the formation of new stars and planets. The elements that make up life on Earth were forged in such stellar explosions.
