LAWRENCE, Kan. (AP) — Researchers at the University of Kansas had a hand in uncovering what might have been about a mile-wide iron asteroid that crashed into Greenland perhaps as recently as 12,000 years ago.

Details of the impact crater beneath the Hiawatha Glacier in remote northwest Greenland were recently published in Science Advances, a multidisciplinary journal.
