This is the first such crater ever found in Greenland and along with all continental ice covers on Earth. According to the size of this crater, the 25th is known on our planet, writes Science Advances.
The 31-kilometer crater is under the ice of Hiawatha. The meteorite had to significantly affect the region, perhaps even in the world, scientists said.
But his story is just beginning to tell.
"The atmosphere had to be separated from particles that had to affect the climate. There may have been many ice breaks and a lot of fresh water has affected the Ners Strait between Canada and Greenland that has affected ocean currents all over the region," said the author John Paden, professor of electrical engineering and computer science at the University of Kansas.
"Evidence suggests that the collision is likely to occur after the arrival of the Greenland continental ice, but a group of researchers are still exploring the exact time," he said.
The discovery was made in 2015, but an international team of scientists has since verified the findings.
The original discovery was based on data from the Arctic Arctic Regional Arctic Survey (PARCA) and the Arctic Ice Tracking Operation IceBridge.
Later, we collected more data using more advanced radar technology.
"The Crater could not be given a direct date, but its condition is very indicative of the fact that it was created when the ice began to cover Greenland, which is why it is below 3 million years, and perhaps only (12,000) , close to the end of the last ice age, "said co-author Professor Kurt Kjaer of the Danish Natural Science Museum GeoGenetics Center.
Scientists intend to try to take the material from the bottom of the glacier to help them learn more about the impact of the collision and its impact on the Earth's life at that time.
