What is Archeoastronomy?
Archeoastronomy is a subset of the science that studies how sky-gazing activities have influenced human cultures and technologies throughout history. It brings together elements from archaeology, astronomy, and anthropology to help answer unresolved questions about ancient societies.
Although many archaeologists may study astronomy to understand past beliefs better or learn more about an ancient culture’s daily life, they focus on studying specific artifacts or architectural features in detail. In contrast, archaeoastronomer’s take a much broader scope when analyzing the movements of celestial bodies across the sky.
In this field, astronomers rely on scientific methods such as calculations, geometry, and physics in conjunction with archaeological resources such as written documents physical remains to determine which prehistoric structures reflect astronomical phenomena.
People & Sky At Different Times
When this is possible, it provides insight into the way people thought about the sky at different times in history and their relationship with surrounding landscapes.
In some cases, culture and society have been greatly influenced by the placement of critical structures which align closely with specific celestial events or phenomena such as moonrises or sunsets. These moments may have been viewed as more significant than others for various reasons among different cultures. In certain societies, they were believed to have a direct influence on human experiences and progress. In contrast, other civilizations may have had a more general approach towards predicting coming changes based on previous observations.
This was especially true during prehistoric times when astronomy played a significant role in determining planting seasons, natural cycles, and even direction during the war.
While most modern cultures, such as the Western world, no longer place much importance on celestial events and phenomena, they can still be used to help us understand how our ancestors lived and struggled in the past. By learning about their relationship with the heavens, we’re able to comprehend more about how complex social structures were created and maintained throughout history.
How did it all start?
There are many reasons why early man began studying astronomy, although this is still a topic of debate among historians who specialize in learning this field. Some argue that sky-watching was primarily used as a tool for farmers who needed to make predictions regarding weather conditions that could negatively impact their harvest or other activities that took place outside their homes and villages. Alternatively, others argue that astronomy was most likely used to observe animals or other human tribes instead of the movement of celestial objects.
While most scientists agree on this latter point, because early calendars were oriented towards seasonal cycles rather than lunar cycles, there are still many unanswered questions regarding the origins of archeoastronomy. According to some researchers, sky-watching may have played a significant role in how early society chose their leaders and created new types of religion, which ultimately impacted scientific advancement during ancient times.
The archaeoastronomer believed sky-gazing was crucial because it provided ancient civilizations with insight into how particular celestial objects moved across the sky at different times during history. This allowed societies to predict better when other events would occur, what the weather conditions might be like, and ultimately how it could impact their daily lives.
What an Archaeoastronomer Does, and How To Become One
Archaeoastronomy is the study of ancient knowledge of astronomy and its role in ancient societies. It is a discipline that draws on many different areas, including archaeology, ethnography, anthropology, history, classics, art history, and ethnology. Its origins go back to the 1930s with Alexander Thom‘s surveys of megalithic sites in Scotland, which led him to believe that their orientations were initially intended to serve as astronomical observatories.
Its development has grown steadily since then with new technologies such as computers, satellite imagery, and Geographic Information Systems (GIS). There are currently about 50 professional archaeologists researching this field worldwide.
Two key questions define an archaeoastronomical study:
- The first question relates to the beliefs and practices of ancient civilizations. These can be inferred from remaining records such as textbooks, artwork, literature, and inscriptions and through ethnographic accounts where neighboring cultures provide comparative material for comparison: some sites have been excavated, which leaves little doubt about their purpose. In contrast, others may only infer that astronomy played a role in the site’s construction or use.
- This leads into the second part of archaeoastronomy: how do we know what they believed? Just because there is no direct record does not mean that their belief systems cannot be determined; modern practitioners of archaeoastronomy must make inferences from remaining evidence and knowledge of the broader cultural, social and intellectual milieu.
Archaeoastronomy does have problems similar to those encountered when studying any other aspect of culture or history. For example, the sites may have been modified over time by humans, so they no longer accurately reflect their original usage. On top of this, there are difficulties with reading the materials found at a particular site because not all cultures kept records of what they thought about astronomical events and phenomena. One way of dealing with this issue is using ethnographic studies in conjunction with archaeoastronomy to connect contemporary beliefs in a particular location to their ancient equivalents.
Can I study archeoastronomy online?
Studying astronomy is no longer difficult, thanks to the internet. There are many resources available for you to learn about this fascinating subject from the comfort of your home.
In addition to finding a course or lecture on any topic that interests you, free tools are available, such as the Coursera website that provides astronomy information and updates to help you stay informed.

Archaeo-astronomy & science tools
Numerous approaches have been used when investigating archaeological sites for possible evidence of astronomical usage, including reading the site’s construction and layout, studying artifact assemblages, or examining iconography related to astronomy. It is also common to combine these techniques with others from archaeology or anthropology. Archaeoastronomical research often utilizes earth science tools such as satellite images, aerial photography, Global Positioning System (GPS) devices, magnetometers, and statistical analysis software. One significant benefit of using this technology is that it can reveal information that would be otherwise impossible to know about a particular location since many ancient sites are threatened by development, farming, or other activities.
One example of how archaeoastronomy can enhance knowledge of the past was demonstrated during the construction of a new road in Bhutan’s Paro Valley. An archaeological team surveyed and excavated pieces of pottery from the area before construction began. They were able to ascertain that those particular sites were occupied during different periods and show that there had been an increase in social complexity over time at those locations based on ceramic evidence. The resulting survey report allowed Indian engineers who specialize in archaeology to build a bridge that considered any potential problems related to cultural heritage at the site.
Archaeoastronomy is a very marginalized topic in most areas of academia, with it primarily being used as an interesting minor footnote rather than an integral part of the study. Yet despite this, archaeoastronomy is far more than just a field linking astronomy and archaeology. It also connects anthropology and even educational research and might be better described as a form of cultural astronomy.
