Poor Darth Vader is slowly becoming homeless. The buildings of Mos Espa, Anakin Skywalker's Tatooine hometown, are in danger of being buried by migrating Tunisian sand dunes, scientists announced this week. The set has been used by scientists as a fixed geographic reference point to study the migration of sand dunes—which now threatens its existence all together. The dunes, which move 10 times faster than similar ones on Mars, have reportedly already made contact with Skywalker's home. Soon, they will swallow up the small "city" once and for all. Maybe Vader can move to the Red Planet?
