The galaxy has become enriched in heavy elements since it formed.What is responsible for the enrichment?

Question

Quizplus · Accepted Answer

The enrichment of the galaxy in heavy elements is primarily due to nuclear reactions in stars, followed by stellar mass loss. As stars undergo nuclear fusion reactions, they create heavier elements that are then released into the interstellar medium when the star dies through processes such as supernova explosions or stellar winds. These enriched materials then become the building blocks for future generations of stars and planets, leading to an overall increase in the metallicity of the galaxy.
