A fifteen year old from Quebec has used satellite photos, Mayan astronomy and his own intuition to solve some questions about the placement of Mayan cities and to discover a new city. William Gadoury loves everything Mayan and was studying Mayan constellations when he overlayed a constellation map on a map of the Yucatan Peninsula. He discovered that the known cities, like Chichen Itza and Uxmal, were exactly lined up with the stars in major Mayan constellations. Using this same map and thought process, he noticed that the third star in the 23rd constellation he was studying was missing. He found satellite images from space agencies, including NASA, JAXA (from Japan) and Google Earth, and discovered a third city where the third star of the constellation said it would be. He has named this city, as yet unexplored on the ground, K'aak Chi, or Mouth of Fire. The lost city has a pyramid that is 86 meters high, as well as 30 other visible (from the photos) structures. It is on the border with Belize. This young man is hoping to go to the International Science Fair in Brazil in 2017 but is lacking in the necessary funds.
