New Delhi: Archaeologists have discovered two suspected Egyptian pyramids and spotted more than 1,000 tombs and 3,000 ancient settlements by using infra-red imaging which revealed the underground buildings.
Dr Sarah Parcak and her team pioneered the work in space archaeology from a NASA-sponsored laboratory in Birmingham , Alabama. The team analyzed images obtained from satellites orbiting 700km above the earth, equipped with powerful cameras that can pin-point objects less than 1m in diameter on the earth`s surface.
The images also revealed that ancient Egyptians built their houses and structures out of mud brick, which is much denser than the soil that surrounds it.
In the documentary `Egypt`s Lost Cities`, the team visited an area of Saqqara (Sakkara),which is believed to be one of the most important archaeological sites in Egypt.
They excavated a 3,000 year old house the image of which was obtained through the satellite imagery. The structure of the house shown in the satellite imagery almost perfectly matched with the one they excavated, validating their findings using infra-red imaging technology.
