Presolar grains, solid fragments of stardust predating the solar system, offer unique insights into stellar and cosmic history. These grains, formed in the outflows of dying stars, hold invaluable data about their stellar origins and processes. Utilizing samples from meteorites and recent asteroid collections, scientists connect the grains to various star types and events, deepening our understanding of our solar system's formation. Despite technological advancements, many mysteries about their survival in harsh interstellar environments persist, prompting continued study in this interdisciplinary field. Presolar grains remain crucial for investigating the cosmic life cycle and solar system evolution.
