NASA Finds Second Impact Crater Under Greenland Ice Sheet

February 19, 2019

Greenland’s ice sheet is the second largest body of ice in the world, so scientists are naturally interested in how it’s changing with the climate and what’s under there. Recent studies of the ice sheet with radar revealed something unexpected: an impact crater. What’s more unexpected than an impact crater? A second impact crater. NASA says it just spotted a second crater just over a hundred miles from the first one, and the team believes they formed at different times.
