Lost pyramids found in Egypt
You'd think it would be pretty hard to lose a pyramid, yet in fact plenty have gone missing in Egypt over the years. Not all of them are giant edifices like the Great Pyramid at Giza. Most are only a dozen or so meters high and were meant to house the body of a Queen. In 2008 the pyramid of Sesheshet was discovered in the desert near Saqqara, and now a survey using infrared satellite imagery has found up to seventeen more.
The survey was conducted by Dr. Sarah Parcak of the University of Alabama at Birmingham. In addition to the 17 suspected pyramids, the survey yielded more than 4,000 other sites, including tombs and towns. Excavations on the ground have confirmed that two of the suspected pyramids are really there and not just natural anomalies. Hopefully there will be further excavations to uncover the rest.
Infrared imaging is commonly used in satellite surveys because it reveals differences in the ground. Stone or harder soil show up as a different shade than loose soil or sand. This has applications in many of fields, and is turning out to be pretty handy in archaeology too.
