Giant impacts under the ice

Scientists have mapped enormous impact craters hidden under the
Antarctic ice sheet using satellite technology.

The craters may have either come from an asteroid between 5 and 11km
across that broke up in the atmosphere, a swarm of comets or comet
fragments.

The space impacts created multiple craters over an area of 2,092km
(1,300 miles) by 3,862km (2,400 miles).

The scientists told a conference this week that the impacts occurred
roughly 780,000 years ago during an ice age.

When the impacts hit, they would have melted through the ice and
through the crust below.

Professor Frans van der Hoeven, from Delft University in the
Netherlands, told the International Geographical Union Congress in
Glasgow that the biggest single strike seared a hole in the ice sheet
roughly 322km (200 miles) by 322km.

Commentary:

Apart from the really dumb translation of Imperial to metric, I admit to being surprised. I never suspected anything like this, and would really like to see the images and data from which the conclusion was drawn.

I'm sure there will be quite a bit of coverage in due course and I can sartisfy my craving for data and a second opinion then...
