A group of experts from the expert group Denmark, Germany and the United States, found a crater 31 miles and 300 feet deep, In the north of Greenland. Big hole It's frozen, which kept him hidden throughout this time.
According to Science Advances, a crater was formed during the Pleistocene period, which extends 2 million years ago 10,000 ago. The meteor that hit the ground it was iron and it was just over a kilometer length.
"Crater It is exceptionally well preserved and it's surprising because the glacier ice is an incredibly powerful erosion agent that would quickly remove the traces of the effect, "explained Professor Kurt H. Kjaer, Geogenetic Center of the Natural History Museum.
"That means it the crater must be quite young from a geological point of view, "he added.
The effect is classified the 25 found violence so far found. A crater formed by a cross is greater than Paris or Washington D.C.. The next step is to find out exactly impact day and how affected the weather climate.
