4 Amazing Archaeological Discoveries Spotted by Satellite

Since human flight was first possible, aerial archaeology has assisted researchers in uncovering previously unknown sites that are imperceptible from the ground. Today, thanks to advanced technology, remote sensing has moved higher above the Earth: Aerial archaeology is now sometimes space archaeology. By examining maps of the planet’s surface taken from space, laptop-based Indiana Joneses can search vast areas for anomalies that could indicate evidence of the human past hidden for centuries. Below are four amazing archaeological discoveries spotted from space.

1. 3100 SETTLEMENTS, 1000 LOST TOMBS, AND 17 PYRAMIDS ACROSS EGYPT

Tanis ruins

Sarah Parcak is a space archaeologist and Egyptologist who since 2003 has discovered numerous archaeological sites across Egypt, all through her computer. Parcak specializes in analyzing satellite images taken from 400 miles overhead, processing the pictures to highlight parts of the electromagnetic spectrum the naked human eye cannot see. This allows her to note anomalies that could denote archaeological sites hidden underground.

It is highly specialized work. The tiny blips on the maps would mean nothing to the uninitiated, but to Parcak they provide clues that have led her to discover the location of 17 potential pyramids, some 3100 settlements, and 1000 lost tombs across Egypt. Parcak also used remote sensing to identify the location of the lost city of Tanis, which gained notoriety when it was featured in Raiders of the Lost Ark. The network of streets and houses of Tanis are completely invisible at ground level, and yet using infrared satellite images, Parcak was able to show the massive extent of the ancient settlement.

Parcak gave a hugely popular TED talk on space archaeology in 2012, and in 2015 was awarded the 2016 $1 million TED prize. She’s used the money to create the citizen science platform GlobalXplorer, which allows anyone to analyze images from space in order to discover more lost archaeological sites across the globe—and spot evidence of looters.
