A “hybrid of Indiana Jones and Google Earth,” archaeologist Sarah Parcak uses satellite imagery to scour the earth for remains and lost cities and now she’s inviting us regular schmoes to do the same. Parcak has just launched GlobalXplorer°, an online tool that means we can help search for these important sites so that archaeologists get there before looters do. She says, “Most people don’t get to make scientific contributions or discoveries in their everyday lives. But we’re all born explorers, curious and intrinsically interested in other humans. We want to find out more about other people, and about ourselves and our past.” Find out more at National Geographic.
