Scientists are refining the search for alien artifacts, physical technosignatures that could range from tiny debris to probes or spacecraft, within and beyond our solar system. New methods include analyzing pre-satellite sky images, studying interstellar objects like ʻOumuamua, and developing screening criteria through SETA research. While most candidates likely have natural explanations, researchers argue that systematic, stigma-free investigation is essential as next-generation telescopes expand the search.
