Archaeologists believe they have unearthed only a small fraction of Egypt's ancient ruins, but they're making new discoveries with help from high-tech allies -- satellites that peer into the past from the distance of space.
Images from space have been around for decades. Yet only in the past decade or so has the resolution of images from commercial satellites sharpened enough to be of much use to archaeologists. Today, scientists can use them to locate ruins -- some no bigger than a small living room -- in some of the most remote and forbidding places on the planet.
Growing up I was a huge fan of the civilizations of antiquity and the field of archaeology. It's pretty exciting - at least for me - to read about new ways to learn even more about ancient societies.
