Mystery of the orbs found in hidden tunnels of Mexican Temple: Robot discovers hundreds of spheres found in cave
Hundreds of mysterious golden-coloured orbs have been found buried in a hidden chamber deep beneath the Temple of Feathered Serpent in Mexico.
The discovery was made by archaeologists from the Mexico National Institute of Anthropology and History, who admit they have no idea what the spheres are for.
A tiny robot called Tláloc II-TC, which has been scanning tunnels deep beneath the famous temple, found the orbs using infrared scanners.
Hundreds of mysterious spheres have been discovered beneath the Temple of the Feathered Serpent, in the pre-Hispanic city of Teotihuacan, just 30 miles from Mexico City
According to archaeologists from the Mexico National Institute of Anthropology and History, the spheres would have appeared to be made of gold because they are covered in jarosite - a bi-product of the oxidisation of pyrite, also known as Fool's Gold
Infrared scanners found the location of the chamber and the orbs. Archaeologists have no idea what the spheres would have been used for, although believe they may have been involved with religious rituals
