in may 2011, the bbc aired a documentary, "egypt's lost cities", describing bbc-sponsored research carried out by parcak's uab team for over a year using infra-red satellite imaging from commercial and nasa satellites. the programme discussed the research and showed parcak in egypt looking for physical evidence. the uab team announced that they had "discovered" 17 pyramids, more than 1,000 tombs and 3,000 ancient settlements outside sa el-hagar, egypt. however, the minister of state for antiquities, zahi hawass, was critical of the announcement and said : "this is completely wrong information. any archeologist will deny this completely".
