Located in Mali West Africa, the Dogon have a rich culture dating to around 3200 BCE, and are believed to have descended from ancient Egyptians. Deeply rooted traditions of the Dogon people speak of the Nommos who visited from a companion star to Sirius. The Nommos are known as amphibious beings who have also appeared in numerous related myths found in the Babylonian, Accadian and Sumerian 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. They tell us how the Nommos shared the knowledge of Sirius with them and left behind several artifacts. One artifact depicting the Sirius constellation carbon dates to 400 years ago, a little over 230 years before astronomers suspected the existence of the companion star.
The Dogon people were first documented over a several year study performed by French anthropologist Marcel Griaule. In his research notes we find conversations between Griaule and a Dogon elder named Ogotemmeli, who speaks of multiple companion stars in the Sirius system. There are entries suggesting the Nommos visited on a very large star ship on several occasions, and the notes also indicate Dogon people knew of Saturn's rings, and the many moons of Jupiter. Every 60 years Dogon people celebrate the cycle of Sirius A and B which rises further questions considering Sirius B's 50 year cycle. Dogon mysteries mention another star in the system, which would be called Sirius C if confirmed by modern telescopes. Nommos are believed to inhabit a planet orbiting Sirius C though mainstream science does not consider the Sirius constellation to be a prime candidate for life.
Earlier astronomical studies by Friedrich Bessel, Alvan Clark, and Walter Adams determined the existence of Sirius B, and for a short time in the 1920's a tiny unknown pinpoint of light was observed, hinting at the possibility of a second companion. Research in 1995 concluded that based on observations of motions in the Sirius system, a red dwarf star about 1/20th the mass of Sirius B theoretically exists. According to a study performed by NASA Astrophysics European Southern Observatory, the Sirius system based on a 6 year perturbation period of Sirius A and Sirius B suggests a second companion star exists, namely Sirius C, likely orbiting around the primary. Light has yet to be observed from the theoretical companion as the light from the primary A and companion B obscure results - Along with the fact Sirius C is suggested to have a maximum 15-20 absolute magnitude, making it very difficult to see.
