Archaeoastronomy is the study of ancient astronomical practices, specifically how they “have understood the phenomena in the sky, how they used these phenomena and what role the sky played in their cultures.” Back in ancient times, there was obviously no technology, but people wanted to understand the natural world. They saw amazing sights (planets, stars, weather, etc.) and wanted to figure out what was going on (rightfully so)! Ancient people all across the globe created structures in order to estimate the positions of objects in the sky, like the Sun, the Moon, stars, and constellations. They tracked constellations’ time of year so they knew when to plant crops and harvest them. The Sun and constellations were used for navigation, especially among sailors traveling by sea. Most notably, ancient civilizations interpreted astronomical patterns as cultural signs. They built incredible structures that were astronomically aligned. One of the most famous examples of archaeoastronomy ever discovered is pictured above. This structure is in Stonehenge, England. It is still unknown who built it and why, however, archaeoastronomers know that the builders used the megalithic structure like a giant calendar to predict the solstices, equinoxes, half-quarter days, and various lunar movements based on where the fun shines. Archaeoastronomers use archaeology, anthropology, astronomy, statistics and probability, and history to discover ancient practices.
