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.
