This study examines the discovery, nomination, and registration outcomes of astronomical materials under Korea’s National Scientific Heritage Registration System, introduced in 2019. By analyzing institutional structures, operational procedures, and statistical data, it finds that although astronomical materials constitute a relatively large proportion among surveyed items, but their share among registered materials remains limited. Nominated materials are concentrated primarily in astronomical books and documentary records, while facilities, instruments, astronomical maps, meteorological materials, and modern astronomical resources are comparatively underrepresented. This tendency reflects not only institutional factors but also the scholarly characteristics of astronomy, where theory, observation, instruments, records, and long-term accumulate over time to form an integrated system. This study argues that effective registration of astronomical materials requires interpretive approaches that account for such structural characteristics rather than a simple quantitative expansion of registrations. It highlights the need for material-type–specific perspectives, stronger continuity between discovery and registration stages, the accumulation of scholarly research, and gradual consideration of modern astronomical materials within the existing institutional framework.
