Celestial cartography is the practice of mapping the stars, planets, and other celestial bodies in the night sky. This field combines astronomy and art to create star charts and celestial maps that help people navigate and understand the universe. It has been used for centuries by various cultures to track celestial events and guide navigation. Historically, celestial cartography has played a crucial role in navigation for explorers and sailors. Notable figures like Ptolemy and Galileo contributed to this field by creating detailed maps of the heavens. Today, modern technology, such as telescopes and satellites, continues to enhance our understanding of the cosmos.
