LONDON (Reuters) – A group of scientists have discovered a giant hole 31 km long, about 1 km deep, under the Hiawata Glacier in northwestern Greenland, according to an article in Science Advances magazine. .
Scientists from the University of Copenhagen used NASA data collected from 1997 to 2016, as well as those from a radar survey of the region. According to the website "Science Advances."
Scientists say the crater has formed as a result of a large meteorite, based on geochemical analysis of sediments at the edge of glaciers.
The researchers could not determine the exact age of the pit, but they were more likely to develop the pit during the Pleistocene period, or the so-called modern era, which began there 2.5 million years and ended about 12,000 years ago.
