A glaciologist has discovered another enormous impact crater under more than a mile of ice in Greenland. This is on the heels of the November 2019 discovery of an impact crater in the same area under the Hiawatha Glacier. The November discovery was the first-ever crater found under ice on Earth.

The two craters are only 183 km (114 miles) apart. The November crater is 30.5 km (19 miles) wide, while the new one is 35.4 km (22 miles) wide. If the newer one can be definitely confirmed as an impact crater, it will be the 22nd largest one on Earth.
Joe MacGregor is the glaciologist who discovered this new crater. He works at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. He was also involved with the first discovery. The discovery of this new crater was published in a paper in Geophysical Research Letters on February 11th.
