The newly-discovered object is located only 114 miles away from a similar one discovered in November. reports citing Dailymail.

A NASA glaciologist has discovered what might be a 22-mile meteor impact crater buried beneath the ice in northwest Greenland. It is unknown when the crater formed, but the scientists believe it happened more than 80,000 years ago, according to a Daily Mail report.

Located beneath Hiawatha Glacier, this is the first crater to be discovered beneath the ice sheet, Daily Mail reports.

"We've surveyed the Earth in many different ways, from land, air, and space — it's exciting that discoveries like these are still possible," said Joe MacGregor, a glaciologist at NASA's Goddard Space Flight Center, who participated in the November discovery of the crater.

"Helping identify one large impact crater beneath the ice was already very exciting, but now it looked like there could be two of them," he added.

According to data obtained by Moderate Resolution Imaging Spectroradiometer instruments on NASA's Terra and Aqua satellites along with those from NASA's Operation IceBridge, the crater is about 22.7 miles (36.5 km) wide, which makes it the 22nd largest impact crater on Earth.
