NASA has released photos of a US military base that was built in the ice in Greenland during the Cold War and later abandoned. The photos were captured by happenstance while NASA scientist Chad Greene was flying over the Greenland Ice Sheet.

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 discovered the former military base Camp Century in Greenland. The discovery was made during tests of a device used to study the interior of glaciers. Although the base's existence was no longer a secret,

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.

"We were looking for the bed of the ice and out pops Camp Century," NASA scientist Chad Greene said after spotting the secret city and Cold War relic in Greenland. Greene and his team were flying over the Greenland Ice Sheet in April,
