The newly revealed structure consists of a 184-by-161-foot (about 56-by-49-meter) platform that encloses a slightly smaller platform originally paved with flagstones. The east side of the interior platform had been lined with a row of columns that once crowned a monumental staircase. A small 28-by-28-foot (8.5-by-8.5-meter) building was centered north-south atop the interior platform and opened to the east, facing the staircase. This enormous open platform, topped with a relatively small building and approached by a monumental facade, has no known parallels to any other structure in Petra. It most likely had a public, ceremonial function, which may make it...

A thousand years after the Vikings braved the icy seas from Greenland to the New World in search of timber and plunder, satellite technology has found intriguing evidence of a long-elusive prize in archaeology — a second Norse settlement in North America, further south than ever known.

Thanks to the careful work of archaeologists, we learned more in the past year about Stonehenge's hidden monuments, Richard III's gruesome death and King Tut's mummified erection. From the discovery of an ancient tomb in Greece to the first evidence of Neanderthal art, here are 10 of Live Science's favorite archaeology stories of 2014. 1. An Alexander the Great-era tomb at Amphipolis [snip] 2. Stonehenge's secret monuments [snip] 3. A shipwreck under the World Trade Center [snip] 4. Richard III's twisted spine, kingly diet and family tree [snip] 5. A teenager in a "black hole" [snip] 6. Syria by satellite...

Their purpose is unknown, and archaeologists are unsure when these structures were built. Analysis of the photographs, as well as artifacts found on the ground, suggest the circles date back at least 2,000 years, but they may be much older. They could even have been constructed in prehistoric times, before writing was invented, scientists say. Though the Big Circles were first spotted by aircraft in the 1920s, little research has focused on these structures, and many scientists are not even aware of their existence, something these archaeologists hope the new aerial images will help to change. The "most important contribution...

Declassified spy photography has uncovered a lost Roman Eastern frontier, dating from the second century AD. Research by archaeologists at the Universities of Glasgow and Exeter has identified a long wall that ran 60 kilometers from the Danube to the Black Sea over what is modern Romania. It is considered the most easterly example of a man-made frontier barrier system in the Roman Empire. Built in the mid-second century AD, 'Trajan's Rampart' as it is known locally, once stood 8.5m wide and over 3.5m high and included at least 32 forts and 31 smaller fortlets along its course. It is...

The number of identified archaeological sites in the Middle East has been tripled by an outdated technology that could not be replicated today—Cold War satellite photographs. The Corona Atlas of the Middle East, unveiled last week in the United States, has added some 10,000 sites to the 4,500 previously known archaeological sites between Egypt and Iran. The photographs, taken mostly in the 1960s for a project managed by the CIA, captured the landscape of the region before it was substantially altered by the spread of modern cities, agricultural development, and the construction of dams and other infrastructure. “Some of these...

A Harvard archaeologist has dramatically simplified the process of finding early human settlements by using computers to scour satellite images for the tell-tale clues of human habitation, and in the process uncovered thousands of new sites that might reveal clues to the earliest complex human societies. As described in a paper published March 19 in the Proceedings of the National Academy of Sciences, Jason Ur, the John L. Loeb Associate Professor of the Social Sciences, worked with Bjoern Menze, a research affiliate in MIT's Computer Science and Artificial Intelligence Laboratory to develop a system that identified settlements based on a...

Enigmatic circular stone formations reminiscent of those in Europe are found on remote hilltops and valleys throughout Saudi Arabia. The rings are 5 to 100 meters in diameter and are surrounded by stone walls a foot or two tall. Some of the rings have "tails" that stretch out for hundreds of meters. From the air, the patterns have a striking resemblance to designs etched in Peru's Nazca plateau. Little is known about the circles and virtually nothing about their purpose.

According to an Italian scientist, a huge network of earthworks, or geoglyphs, is visible in satellite imagery of a large area, over 463 square miles, in the surroundings of the Titicaca Lake, Peru. Amelia Carolina Sparavigna, professor at Italy’s Politecnico di Torino, claims the patterns she discovered while studying satellite pictures near the Titicaca Lake. She says the shapes are the result of an almost unimaginable agricultural effort of Andean communities centuries ago. “People created a system of terraced hills and raised fields, which were large elevated planting platforms, with the corresponding drainage canals, to improve soil, temperature and moisture...

They stretch from Syria to Saudi Arabia, can be seen from the air but not the ground, and are virtually unknown to the public. They are the Middle East's own version of the Nazca Lines — ancient "geolyphs," or drawings, that span deserts in southern Peru — and now, thanks to new satellite-mapping technologies, and an aerial photography program in Jordan, researchers are discovering more of them than ever before. They number well into the thousands. Referred to by archaeologists as "wheels," these stone structures have a wide variety of designs, with a common one being a circle with spokes...

Giant stone structures in the Azraq Oasis in Jordan They stretch from Syria to Saudi Arabia, can be seen from the air but not the ground, and are virtually unknown to the public.

"Previous spatial analysis of the regional topography has shown there are major watersheds that are dry today but which would drain north from these [the Ahaggar and Tibesti ranges in the south] mountains towards the Mediterranean," says Coulthard, et. al. "Satellite imagery reveals traces of major river channels linked to these watersheds, now partially buried under sand dune deposits." It "provides the first strong quantitative evidence for the presence of three major river systems flowing across the Sahara during MIS 5e [Marine Isotope Stage 5e, or 130,000 years ago]".* "Whilst we cannot state for certain that humans migrated alongside these...

Satellite images have revealed that a network of ancient rivers once coursed their way through the sand of the Arabian Desert, leading scientists to believe that the region experienced wetter periods in the past... Over the course of five years the researchers will study the landscape features and excavate sites of likely archaeological interest, using the network of water courses as a map. They will use the latest dating techniques to pinpoint the ages of fossils of animals, plants and different stone tool technologies and compare the similarities and differences displayed in the region's rock art. The team's main focus...

Dr. Richard Freund to be featured in a National Geographic Channel film; public invited to preview on Wednesday. Spend a little time with Dr. Richard Freund of the University of Hartford, and you might be convinced that the lost city of Atlantis is buried deep within a swamp in southern Spain. Freund, who directs the university's Greenberg Center for Judaic Studies, worked with a team of Spanish, American and Canadian scientists to examine a muddy swamp in Spain that was first noted as a possible location for Atlantis by a German scientist looking at satellite photos in 2003. Freund's 2009...
