Following the results of an international team of researchers from Denmark, Germany and the United States, it is positioned amongst the 25 largest crater in the world with a diameter of more than 31 kilometers.
The crater was discovered when one kilometer-long iron meteorite collapsed in northern Greenland and was buried beneath the ice of Iyad.
Professor of the Center for Geodesy of the Natural History Museum, Kurt H. Kaier explains: "The crater is very well preserved, and it is surprising, as ice is an excellent erosive agent that allows you to quickly eradicate traces of impact. Denmark.
"That is, the crater should be very young in geological terms," he said.
Researchers suggest that the craters were formed at Plastocene about 12,000 years ago, until the end of the last ice age, but many studies are needed to determine the date.
The first signs of the crater were until July 2015, when researchers examined a new map of topography under Greenland Ice Leaf and noticed a large circular depression that had not been previously identified.
They decided to fly from the Gaivat Glacier with a new and powerful ice radar developed by the Kansas University of Germany (Germany) and to send Alfred Wegener's research aircraft in Germany.
The modern radar "surpasses all expectations and depicts depression with delusional particles," says NASA's ice ocean, Joseph McGregor.
In order to confirm radar data, the study of rocky rocks near glaciers and sediments revealed quartz, glass and other elements associated with meteorite effects.
The next step in the research is to determine the effect of the impact and how and how the Earth's climate is affected.
