Islamic astronomy refers to the study of celestial bodies and their movements by scholars in the Islamic world from the 8th to the 14th centuries. This period saw significant advancements in observational techniques and the development of astronomical instruments, such as the astrolabe and quadrant. Islamic astronomers built upon the knowledge of earlier civilizations, including the Greeks and Indians, and made important contributions to the field. Notable figures in Islamic astronomy include Al-Battani, who improved the accuracy of celestial measurements, and Al-Farghani, who wrote influential texts on the subject. Islamic astronomers also created detailed star catalogs and introduced the use of trigonometry in their calculations, laying the groundwork for future developments in astronomy.
