Stellar nucleosynthesis is the process by which stars produce new elements through nuclear fusion reactions in their cores, transforming hydrogen into helium and other heavier elements up to iron. This process is fundamental to the chemical evolution of the universe, as it enriches the interstellar medium with elements necessary for the formation of planets and life.

The interstellar medium (ISM) is the matter and radiation that exists in the space between the star systems in a galaxy, consisting primarily of gas (in ionic, atomic, and molecular form) and dust. It plays a crucial role in the life cycle of stars, influencing star formation, and is a key component in the dynamics and evolution of galaxies.
