Mystery Antarctic ‘Crater’ Could Be House-Sized Meteor Blast
Scientists conducting a routine aerial research flight above East Antarctica noticed a strange ring-like structure in the normally flat and featureless ice.
It appeared to be a series of broken ‘icebergs’ surrounded by a 2km (1.24 miles) wide circular scar, surrounded by a few other smaller circular scars in the ice.
German scientists from the Alfred Wegener Institute on a routine survey flight spotted the 2km (1.24 mile) wide crater (main picture) in the ice shelf off the Princess Ragnhild Coast of East Antarctica, which can be seen in the north east corner of the continent in the inset map.
The location matched those of a meteorite spotted by Australian scientists at the Davis Research Station off the eastern coast of Antarctica in 2004. Low frequency sound detected in 2004 around the world also suggested a 7-10 metre wide meteorite exploded Antarctica and rained down debris onto the ice
