- Scientists have uncovered an asteroid impact crater, bigger than the area of Paris, buried beneath a kilometre of snow and ice in northern Greenland, .
- This is the first time that a crater of any size has been found under one of Earth’s continental ice sheets.
- According to the study published in the journal Science Advances, the crater measures more than 31 km in diameter, placing it among the 25 largest impact craters on Earth .
- The crater was formed when a kilometre-wide iron meteorite smashed into northern Greenland.
- The crater was first discovered in July 2015 as the researchers inspected a new map of the topography beneath Greenland’s ice-sheet.
- The 20-tonne iron meteorite sits in the courtyard at the Geological Museum in Copenhagen.
