Annotation: This article explores the significant contributions of four prominent figures in the history of astronomy: Alfraganus, Qadi-zadeh Roumi, Al-Kashi, and Ulugh Beg. These scholars, hailing from the region now known as Uzbekistan, played pivotal roles in the astronomic renaissance of the Turkic and Islamic Golden Age. Their work in astronomy laid the foundation for many modern principles in the field. Alfraganus provided revised and accurate data on celestial motions, which were instrumental for later explorers. Qadi-zadeh Roumi's precise calculations and contributions to stellar catalogues advanced the understanding of celestial bodies. Al-Kashi's work on pi and trigonometric functions significantly impacted mathematical astronomy. Timurid governor, Ulugh Beg's establishment of an advanced observatory and his comprehensive star catalogue corrected many of Ptolemy's errors and provided a more accurate understanding of the night sky. Collectively, their contributions highlight Uzbekistan's pivotal role in the astronomic renaissance and continue to inspire modern scholars, specially the Jadids, who want to revive science in Central Asia.

Keywords: Alfraganus, Qadi-zadeh Roumi, Al-Kashi, Ulugh Beg, Uzbekistan, Islamic-Turkic Golden Age, astronomy, celestial motions, stellar catalogue, trigonometry, observatory.
