A few months after the first NASA second giant impact crater under Greenlandic ice
Science a Few months after scientists first giant crater - a little more than Gent - discovered, now going a second crater in Greenland. That would be with a width of 36.5 kilometres, even bigger than the first. Probably was the impact of the impact is also much larger.

The crater is located in the northwest of Greenland, and was between 100,000 years and 100 million years ago. In addition, the crater a few square meters larger than the instance that in november 2018 was discovered. That writing, scientists in the magazine Geophysical Research Letters. “It's exciting that discoveries such as this were always possible,” says researcher Joe MacGregor. the

The first instance in Greenland - nearly 31 kilometers wide - was found under the Hiawatha glacier in Greenland and would have been the result of a meteorite impact. The second crater is located about 183 kilometers away from the first crater, and up to two kilometres deep, hidden under a thick layer of Greenlandic ice. No wonder that scientists are the giant specimen is not immediately found.

For the discovery of the first crater went scientists also not actively looking for it. They assumed that all craters by erosion, or abrasion by the ice, completely gone.

It goes without saying that researchers to immediately continue searching for other instances once the first large crater in Greenland suddenly discovered. And that's what happened with the necessary equipment, on land, at sea and in the air. So essentially the satellite images of NASA is finally on a bowl-shaped structure, about 183 kilometers away from the first meteor impact. That bowl-shaped structure confirms that the crater is likely to be the result of a strike.
