The History of Astronomy And Cosmology in Africa

Last Updated on March 3, 2026 by Tsiyon Hone

Despite the known notation that Africa has no history in astronomy, many sites evidence the existence of African astronomy and cosmology, dating back to civilizations that meticulously tracked celestial bodies and integrated them into their lives. This journey is deeply connected and wonderful, with megalithic structures and cultural beliefs. Africa’s astronomical legacy extends to its societies, calendars, and mythology, and continues to be shaped by African astronomers, who continue to push the boundaries of our understanding of the universe through cutting-edge research and international collaboration. In this article, we will explore some communities that established a strong foundation for African astronomy and how they used this information in their daily lives.

Adam’s Calendar

In Mpumalanga, South Africa, lies a strange stone circle known as Adam’s Calendar, or Africa’s Stonehenge. Estimates place its age at around 75,000 years, making it one of the oldest man-made structures in the world.

Namoratunga

If we go to Kenya on the western side of Lake Turkana, approximately 50 meters off the Lodwar-Kalokol road, is Namoratunga, a group of 19 pillars encircled by a ring of more than 20,000 stones.

Scientists have long disagreed over whether Namoratunga, sometimes referred to as Namoratunga II or the Kalokol Pillar site, is a potential archaeo-astronomical site like Stonehenge in Europe.

There are 19 Namoratunga pillars are aligned to seven star systems (Sirius, Central Orion, Bellatrix, Aldebaran, Triangulum, Pleiades, and Saiph), each of which leans differently from the others. More than seventy of these standing stones are aligned with enigmatic geometric patterns.

Researchers are still baffled by the importance of this distinctive burial building, which makes Namoratunga one of the most scientifically rich, yet underexplored, sites in sub-Saharan Africa. Hundreds of Turkana now congregate at Namoratunga in December for spiritual and religious reasons. If you find yourself in the vicinity of Lake Turkana, it might be good to visit the site.

Nabta Playa

Regarded by many as the archetypal case of an unresolved mystery, the Nabta Playa , located in southern Egypt and believed to predate Stonehenge by over 2,000 years. It is believed to have been built by a cattle-worshiping community, who used it to commemorate the summer solstice and the start of the monsoon season.

The stone slabs and megalithic monuments of Nabta Playa were constructed over years of habitation by the nomadic people who passed through the area over thousands of years. The most significant structure among them all is the calendar stone circle. The circle is made up of four pairs of large stones and then an assortment of smaller stones.

In research published in 2007 about the complex of stones, archaeoastronomers and archaeologists confirmed that the stones were in possible alignment with the stars Sirius and Arcturus, the star system Alpha Centauri, and the Belt of Orion. After the first paper was published in 1998, tourists and visitors who were able to locate the stone circles began defacing the stones and moving some, eventually changing the alignment. The area had been untouched for over 5,000 years before then.

Dogon

Deep within the heart of Mali, the Dogon people hold a secret as vast as the starry expanse above – their profound knowledge of the Sirius star system. This knowledge, woven into their traditions and rituals, extends far beyond what one might expect from an ancient African society.

The Dogon claim to have received this celestial wisdom from the Nommo, amphibious beings said to have arrived from a world orbiting Sirius. According to their traditions, Sirius B is an incredibly dense star, a fact remarkably aligned with modern scientific discoveries. Their rituals and mythology incorporate a 52-year cycle, which some have linked to the orbital period of Sirius B, although scientific observations suggest a slightly longer.

The enduring allure of the Dogon and Sirius lies in the captivating questions it raises. Does their knowledge stem from ancient wisdom or a more recent cultural exchange? The answer, perhaps, lies somewhere in between. Regardless of its origin, the Dogon’s knowledge serves as a powerful reminder of humanity’s innate curiosity about the cosmos and the enduring mysteries that lie among the stars.

Africa has a rich and intriguing history of astronomy, ranging from the megaliths of Nabta Playa to the Dogon people’s celestial understanding. These illustrations demonstrate a profound interaction with the universe that shapes calendars, rituals, and even cultural mythology, rather than only a superficial study of the night sky.

Our continent’s astronomical heritage continues to evolve. Modern African astronomers are making significant contributions to our understanding of the universe, using powerful telescopes and collaborating with international teams. This blend of ancient traditions and cutting-edge science ensures that Africa’s role in unlocking the secrets of the cosmos remains bright.
