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.
An initial excavation has already confirmed some of the findings including of two suspected pyramids.
An infra-red satellite image shows a buried pyramid, located in the centre of the highlight box.
"We were very strongly doing this research for over a year. I could see the data as it was rising , but for me the "A-Ha" moment was when I could step back and look at everything that we'd found and I couldn't believe we could locate so many sites all over Egypt."
The team analyzed 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.
