Archaeoastronomy is the study of how ancient cultures understood and utilized celestial phenomena. It combines aspects of archaeology and astronomy to explore how people in the past observed the sky, including the movements of the sun, moon, and stars. Researchers analyze ancient structures, artifacts, and texts to uncover the astronomical knowledge of these societies. This field helps us understand the significance of celestial events in ancient rituals, calendars, and navigation. For example, many ancient monuments, like Stonehenge, are believed to have been aligned with specific astronomical events, such as solstices and equinoxes, reflecting the importance of the cosmos in their daily lives.
