Scientists Detect Massive Impact Crater Beneath Greenland’s Ice Sheet

According to a report by Gizmodo, scientists have discovered an unusually large asteroid crater measuring 19 miles wide under a continental ice sheet in Greenland. The crater is roughly the size of Paris, and is among the 25 largest asteroid craters on the planet. A new study published in Science Advances suggests that an iron-rich asteroid struck Greenland's ice-covered surface at some point between 3 million and 12,000 years ago, leaving just a tiny 2 million 90,000 year window for the catastrophic event to have occurred. Nicolaj K. Larsen, a co-author of the study, explained to Gizmodo, “It is correct that the crater is not well dated but there’s good evidence that it is geologically young, that is, it formed within the last 2 to 3 million years, and most likely it is as young as the last Ice Age which ended around 12,000 years ago."
