Satellite archaeology MAY 27 2011
Archaeologists are using infrared satellite images to find several undiscovered pyramids and ancient settlements in Egypt.
The team analysed images from satellites orbiting 700km above the earth, equipped with cameras so powerful they can pin-point objects less than 1m in diameter on the earth's surface.
Infra-red imaging was used to highlight different materials under the surface.
Ancient Egyptians built their houses and structures out of mud brick, which is much denser than the soil that surrounds it, so the shapes of houses, temples and tombs can be seen.
