After the Greenland ice, scientists discovered a larger crater behind Paris


Greenland 12,000 A few years ago, a huge iron meteorite dropped, leaving behind a larger crater over Paris, recently discovered under ice with modern radar, scientists announced this week.

This is the first such crater ever found in Greenland and in common with all continental glaciers on Earth. According to the size of this crater, it is known to everyone on our planet, says Science Advances magazine.

Baptism 31 kilometers is under the Hiavath ice. The meteorite had to make a significant impact in the region, perhaps even in the world, scientists said. But his story is just beginning to speak.

"The atmosphere must be thrown out of the particles that had to affect the climate. Perhaps there was a lot of ice breaks, and lots of fresh water hit the Ners Bay between Canada and Greenland, which affected ocean currents across the region," said one author of John Paden, professor of electrical engineering and computing at the University of Kansas.

"Evidence suggests that the crash probably came after the formation of the Greenland continental ice, but the team of researchers is still exploring the exact time," he said.

The discovery was made in 2015, but the international team of scientists has since confirmed the findings.

The first discovery was made based on the NASA Arctic Assessment Program (Arctic Regional Climate Assessment Program, PARCA) and data from Operation IceBridge Polar Ice Tracking Mission.

Later, more data was collected using advanced radar technology.

"It was not possible to give the crater a direct date, but its condition is very suggestive of the fact that it was formed after the ice began to cover Greenland, so it is below 3 million years, and perhaps (formed) only 12 thousand years, end of the end of the last ice age, "said co-author Professor Kurt Kjaer of the Danish Museum of Natural History, GeoGenetics Center.

Scientists plan to try to take material from the bottom of the glacier to learn more about the impact of the collision and its impact on the Earth's life at that time.
