Scientists have discovered an incredible discovery in the glacier: 36 kilometers in diameter

Ученые обнаружили невероятную находку в леднике: 36 километров в диаметре

Scientists from NASA announced the discovery of yet another powerful impact crater under the ice cover of Greenland. The new object has a width of about 36 kilometers and, like the previous crater, is poorly understood

This publication reports “Hvil”.

In November of last year employees the University of Copenhagen conducted in Greenland topographic measurements using a special radar, capable of catching radio waves that have passed through the ice and reflected the hard surface of the island. The study was able to detect previously unknown impact crater, hidden under a glacier Hiawatha (Hiawatha) North-West of Greenland. Its diameter was 31 km and with the help of the conducted simulation it was found out that to leave him would a meteorite the size of about a mile.

Joe McGregor (Joe MacGregor), the scientist from space flight Center NASA’s Goddard in Greenbelt, Maryland, also participated in the study crater. Now he became the leader of a research team that discovered a second crater under the ice of Greenland. Relevant work published in the journal Geophysical Research Letters.

The first finding was considered unique because of several features. In addition to the strikingly circular shape of the crater and characteristics of the elevation rim and Central mound, scientists have discovered a large number of minerals. A new crater has the same trace minerals and, as experts believe, was the result of a meteorite is confirmed by 11 various remote sensing programs. These data show impressive dent on the Earth’s surface, 183 km South-East of the location of the first crater. It is less round than Hiawatha, but scientists have noted the similarity of edges and internal distinctive peaks of craters.

Despite the similarity of the two objects, scientists believe that even if they were formed by impact of meteorites on Earth, they probably were created separately from each other. The team believes that the newly discovered structure was formed not before 100 thousand years ago, while the upper limit of Hiawatha — about 11.7 thousand years ago.

Both the impact crater will be explored by professionals before they will be able to tell something about the history of the fall of meteorites on the Earth. And while the team enjoys the study of these massive structures hidden deep beneath the ice — 930 meters (Hiawatha) about two kilometers (a new crater).

We will remind that on one of the coasts of Antarctica, scientists have discovered hundreds of mummies, which were buried under the ancient snow.

Still recall that iceberg A-68 broke in the summer of 2017.

It was also reported that scientists have discovered in Antarctica found a deep depression.
