Most teenagers kill time playing video games，or surfing TikTok.Not William Gadoury，a 14-year-old from Matha，Quebec.William Gadoury has been crazy about the Mayans for most of his childhood，ever since his grandparents bought him books about the civilization.What started as a hobby at age 12 snowballed into serious research，and he theorized that the locations of Mayan cities might correspond to stars in Mayan constellations（星座）.
   Using ancient books，Gadoury analyzed 22 Mayan constellation maps and covered the positions onto Google Earth images of the Yucatan Peninsula，which to this day is home to large local populations and some best-preserved architecture from Mayan culture.He would track the constellations from Google Earth using special sheets，covering them onto the position of Mayan cities on a paper map.The teen was able to show that 117 Mayan cities matched up with the position of the stars，with the brightest stars representing bigger cities.
   But when Gadoury was working on the 23rd Mayan constellation，he found a conflict：three stars，but only two ancient cities on Google Earth.The third star pointed to a location on the Mexico-Belize border.However，the area was covered with thick jungle，leaving Gadoury stuck.
   Luckily，he asked NASA for images from their RADARSAT-2 satellite.Indeed，there was a square，man-made-looking structure in the heavy forest.Gadoury then learned a fire had swept across the region，thinning out the grass cover.He found images from the agency，and eventually concluded that there was indeed a city there.
   Gadoury's findings eventually took him into the jungle in 2022 to search on foot，along with scientist Francisco Bell.The team discovered a farming village deep in the Mexican jungle，which showed the "backbone" of the Maya's long-term success，which was down to their ability to work the land and support large cities.
