In 2026, the Poltava Gravimetric Observatory of the S.I. Subbotin Institute of Geophysics of the NAS of Ukraine will celebrate its 100th anniversary, which is a landmark event for the development of national and global Earth sciences. Founded in 1926 by the prominent scientist Alexander Orlov, the institution played a key role in creating the gravimetric map of Ukraine, exploring mineral resources, and formally proving the existence of the Earth's liquid core. Over the past century, the observatory has significantly expanded its research areas, encompassing studies of the deep structure of the Earth's crust, radio astronomical observations using "URAN-2" telescopes, satellite geodesy, and the monitoring of local seismic activity. Despite the modern challenges of war, the observatory remains a symbol of the resilience of academic science, successfully combining fundamental research with the practical monitoring of natural and anthropogenic processes.
