Stellar nucleosynthesis is the process by which elements are created within stars through nuclear fusion reactions. This process occurs in the high temperatures and pressures found in the cores of stars, where lighter elements such as hydrogen and helium are fused together to form heavier elements like carbon, oxygen, and iron. These newly formed elements are then released into the surrounding interstellar medium through processes such as supernova explosions, enriching the universe with a diverse array of elements. Stellar nucleosynthesis is a key concept in understanding the evolution and composition of stars, as well as the origin of the elements that make up our planet and the universe as a whole.
