But at 22 miles wide, when the meteorite hit, which was approximately 79,000 years ago, it would have been big enough to alter the global climate.
The researchers used images from NASA’s Terra and Aqua satellites to notice strange anomalies on the ground.
Following this, the experts coincided the satellite information with topographic maps to discover the new crater.
Joe MacGregor, a glaciologist with NASA’s Goddard Space Flight Center in Greenbelt, Maryland, who participated in both findings, said: “I began asking myself ‘Is this another impact crater? Do the underlying data support that idea?
