Based on his own theory - that the Maya chose the location of their cities following constellations, he realized that there must be another undiscovered city in the Yucatan Peninsula in Mexico. Satellite images of the area have confirmed his hypothesis.

As reported in the Spanish newspaper ABC, William Gadoury has become a little star in the eyes of the Canadian Space Agency (CSA), NASA, and the Japanese space agency (JAXA) with this finding, which will be released shortly in the most prestigious scientific journals.

William, reportedly a passionate student of the Maya world, found 22 Maya constellations in the Madrid Codex, and superimposed them onto a Google Earth map of the Yucatan Peninsula. Then he realized that the stars corresponded to the location of the 117 Maya cities, and also the brightest stars coincided with the most important cities.
