Korean astronomy has a rich history that dates back to ancient times, with records of celestial observations found in texts like the Samguk Sagi. Early Korean astronomers developed calendars based on lunar cycles and created star maps, contributing to the understanding of the night sky. During the Joseon Dynasty, advancements in astronomy were made, including the construction of observatories like the Cheomseongdae. Korean scholars, such as Heo Jun, made significant contributions to the field, blending traditional knowledge with new techniques, which helped improve agricultural practices and navigation.
