It is estimated that he hit the Earth 12,000 years ago
A spectacular discovery under the ice of northern Greenland, a huge crater of at least 31 km in diameter – more than Attica and Paris – caused by a 1 km meteor collapse, the international scientific team said.
The impact may have occurred relatively recently, even 12,000 years ago. Scientists from Denmark, Germany (the Alfred Vagnerer Institute) and the United States of America (University of Kansas), led by Professor Kurt Kaiar of the University of Copenhagen, published a publication in the Science Advances magazine, suspect that this is one of the 25 largest landing crater Earth.
It is estimated that the "culprit" for the Crater is a meteorite composed mainly of iron, which fell to Greenland, and then "buried" under ice almost 1 km. This is the first time a bubble of any size of our planet's ice has been found beneath them. The original discovery was made in 2015 in the Hiavath Glacier area, but lasted for 3 years, until further study was confirmed by the "radar" underneath the radar.
"The crater is impressively well preserved, which is unexpected, because the glaciers have an incredibly high level of corrosion, which would usually need to erase the traces of impact." "If that did not happen, it means that the crater is quite young geologically, so far it was not possible to directly carry out the crater , but we estimate that it was created after the ice is covered by Greenland, so it is less than 3 million years old and probably the latest 12,000 years towards the end of the last ice age. "Kjaier said.
Geological Museum in Copenhagen already owns 20 tons of iron, found near the crater point. Scientists wonder how and how many climatic and living conditions could affect the fall of the great meteorite on Earth.
