Lost Cities Of Egypt
There was a program on TV on Monday night about the lost cities of Egypt if you missed it we thought you might find this interesting.
Seventeen lost pyramids are among the buildings identified in a new satellite survey of Egypt.
More than 1,000 tombs and 3,000 ancient settlements were also revealed by looking at infra-red images which show up underground buildings.
Initial excavations have already confirmed some of the findings, including two suspected pyramids.
"To excavate a pyramid is the dream of every archaeologist," says US Egyptologist Dr Sarah Parcak.
She has pioneered the work in space archaeology at the University of Alabama in Birmingham, and says she was amazed at how much she and her team has found.
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.
"It just shows us how easy it is to underestimate both the size and scale of past human settlements," says Dr Parcak.
And she believes there are more antiquities to be discovered.
We find this quite interesting here at Greengates Builders Merchants Accrington, Lancashire, what else could they find out about us from outerspace?
