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.

NASA scientists accidentally uncovered Camp Century, a hidden Cold War base under Greenland's ice, using advanced radar technology in April 2024. This discovery not only brings historical artifacts to light but also assists in ice sheet studies critical for understanding future sea level changes.

A NASA scientist uncovered a Cold War military base under ice in Greenland this April, as reported by NASA’s Earth Observatory on Monday. Several months ago, scientist Chad Greene was flying aboard a Gulfstream III with engineers in an effort to monitor a radar instrument on the Greenland Ice Sheet.
