NASA's satellite images and observations from space helped archaeologists around the planet to make some stunning discoveries. Recently, NASA helped discover remains of mysterious ancient lost city hidden beneath a dense forest. 

The ancient city is believed to have been inhabited by ancient native Americans. The "remote-sensing equipment" was used by scientists as they were able to zoom onto ancient site located in Oklahoma. What they found is a 10,500-year-old settlement hidden deep inside a dense forest.

Experts believed that this ancient city was inhabited by hunter-gatherers who lived in the area. The ruins of the ancient city were found in the vicinity of the Beaver River in western Oklahoma through NASA's LIDAR technology.

Dubbed as Teledyne Optech Lidar, the device recreated a 3-D model of the surface including glass, bushes and trees. It also has the ability to create a "bare-earth" version.

Consequently, this allows scientists to "see structures or features that were so overgrown that they wouldn't be obvious at all to someone on the ground," says Paul LaRoque, vice president of special projects at Teledyne Optech.

This groundbreaking laser-based remote sensing equipment has allowed experts to peer through thick layers of forest offering a clear view of the fossils and bones hidden below the surface.

Archaeologist Lee Bement said that NASA's sophisticated tools have "been useful in delineating where we need to concentrate our efforts."

"It saved us a lot of time and effort."

"You'll never find bison bones with airborne LIDAR, but you can find the geological features that suggest a place to look," said Meg Watters, a remote sensing expert.

Interestingly, the LIDAR Technology has helped make many stunning discoveries.
