A radar image taken by Nasa scientists while flying over Greenland has revealed an abandoned Cold War -era “city” under the ice. Scientists and engineers took the radar image in April 2024 as they flew over northern Greenland aboard Nasa’s Gulfstream III jet.

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.

NASA scientists have made a surprising discovery beneath Greenland's thick ice sheet: an abandoned Cold War-era military base called Camp Century, now buried 30 meters below the surface.
