Danish and Swedish researchers have dated the enormous Hiawatha impact crater, a 31 km-wide meteorite crater buried under a kilometer of Greenlandic ice. The dating ends speculation that the meteorite ...

Scientists have discovered a possible second impact crater buried under more than a mile of ice in northwest Greenland. This follows the finding, announced in November 2018, of a 19-mile-wide crater ...

Greenland's ice sheet is the second largest body of ice in the world, so scientists are naturally interested in how it's changing with the climate and what's under there. Recent studies of the ice ...

A team of international researchers has verified the discovery of the first meteorite impact crater ever found deep beneath the Greenland ice sheet. Found under the Hiawatha Glacier, the crater is ...

A giant asteroid impact crater has been found under Greenland's Hiawatha Glacier. Advanced radar revealed the enormous structure. Scientists analysed meltwater sediments, finding shocked quartz and ...

Buried beneath a half mile of snow and ice in Greenland, scientists have uncovered an impact crater large enough to swallow the District of Columbia. The finding suggests that a giant iron asteroid ...

Map of the bedrock topography beneath the ice sheet and the ice-free land surrounding the Hiawatha impact crater. The structure is 31 kilometers wide, with a prominent rim surrounding the structure.

When we look at the moon, either through a pair of binoculars, a telescope, or past footage from the Apollo missions, we see a landscape that's riddled with what appear to be massive sinkholes. But ...
