A new remote sensing technology has peeled away layers of mud and rock near Peru's Cahuachi desert to reveal an ancient adobe pyramid, Italian researchers announced on Friday at a satellite imagery conference in Rome.

Via Quickbird, Masini and colleagues collected high-resolution infrared and multispectral images. After the researchers optimized the data with special algorithms, the result was a detailed visualization of a pyramid extending over a 97,000-square-foot (9,000-square-meter) area.
