Today’s Image of the Day from NASA Earth Observatory describes a huge meteorite impact crater that was discovered beneath the ice in Greenland.

The massive crater, which is around 1,000 feet deep and 19 miles long, was uncovered by an international research team from the University of Copenhagen’s Centre for GeoGenetics.

The crater was originally found using NASA data in 2015, and the experts have worked for three years to verify it. The team believes that an iron meteorite about half a mile wide crashed into northwest Greenland around 3 million years ago.

“The crater is exceptionally well-preserved, and that is surprising because glacier ice is an incredibly efficient erosive agent that would have quickly removed traces of the impact,” said study lead author Kurt Kjær
