NASA eyes giant ‘meteorite’ crater under the ice in Greenland

NASA scientists have spotted a huge crater under the ice in Greenland which may be the result of a huge meteorite strike on the Earth.

The crater, which is slightly more than 22 miles wide, one of the largest meteorite impact sites on Earth, if it be proved that the result of a space rock. The crater is buried under more than a mile of ice.

In November 2018, scientists announced the discovery of a 19-mile-wide crater under the Greenland Hiawatha Glacier. Experts say that the crater was formed by a meteorite that struck Earth “with less than 3 million years ago” and probably also “rocked the Northern Hemisphere.”

The crater under the Hiawatha Glacier is the first of its kind discovered under the Earth’s polar ice caps.

If the newly-discovered 22-metre-wide crater is the result of a meteorite, it would be the 22nd-largest impact crater found on Earth, according to NASA.

With the help of NASA satellite data, Joe MacGregor, a glaciologist with the agency’s Space Flight Center in Greenbelt, MD., established in the second possible crater 114 miles from Hiawatha Glacier.

“I started asking myself:” Is this another impact crater? Do the underlying data to support that idea?’,” he said in a statement. “Help to identify a large impact crater beneath the ice was all very exciting, but now it seemed as though there would be two of them.”

The researchers also studied the data from commercial satellites and radar images of the rocks collected by NASA’s Operation IceBridge.

The crater is described in a study published in the journal Geophysical Research Letters.

After analyzing radar data, ice monsters and erosion, scientists say that, despite the proximity of the two craters, they do not appear to have formed at the same time. Computer models were also used to track the production of large craters on Earth, who said that the craters of the formation close to each other, without a separate impact, in accordance with the planet of the history.

Other geographically close but nothing craters are found in Ukraine and Canada, according to NASA. In each pair, the age of the craters are different.

A small piece of an asteroid or comet is also known as a meteor. When it is in the atmosphere of the Earth, is it a meteor or a fireball or shooting star. The pieces of rock that hit the ground, valuable to collectors, are the meteorites.
