NASA has discovered Camp Century, a hidden Cold War-era military base buried 100 feet beneath Greenland's ice using advanced radar technology. The base, part of the secret "Project Iceworm," was designed for nuclear missile deployment but was abandoned in 1967.

Scientists now have a clearer picture of Camp Century, an abandoned U.S. military base long hidden under the ice in Greenland, thanks to a NASA research team's good luck.

The discovery occurred while the NASA team was testing the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) system aboard a Gulfstream III aircraft.
