Located in Mali West Africa, the Dogon have a rich culture dating to around 3200 BCE, and are believed to be a hybrid ethnic group descended from a mixing of the ancient Egyptians of North Africa with various other sub-Saharan tribal populations.
Deeply rooted traditions of the Dogon people speak of the Nommos who visited from a companion star to Sirius. The Nommos are known as advanced beings who have also appeared in numerous related myths found in the Sumerian and other Mesopotamian cultures.
Sirius' companion star has a 50 year elliptical orbit and is not visible to the naked eye. According to some research, modern astronomers did not know the companion star existed until the Dogon myth was discovered.
