Initial excavations have already confirmed some of the findings, including two suspected pyramids.
The work has been pioneered at the University of Alabama at Birmingham by US Egyptologist Dr Sarah Parcak.

She says she was amazed at how much she and her team has found.
"We were very intensely doing this research for over a year. I could see the data as it was emerging, but for me the "Aha!" 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.
"To excavate a pyramid is the dream of every archaeologist," she said.

I don't know which is cooler--that they found thousands of buried archeological dig sites or that it is now possible to claim the title of "Space Archaeologist."
