Earth was hit by massive 19 mile-wide asteroid more than 3 billion years ago that caused cliffs to crumble and changed the way our planet evolved

Scientists have found evidence of a massive asteroid, 12 to 19 miles (20 to 30km) wide, that struck Earth more than 3 billion years ago.

The asteroid would have hit with an impact larger than anything humans have experienced.

The discovery was made in tiny glass beads called spherules, found in north-western Australia, which were formed from vaporised material from the asteroid impact.

'The impact would have triggered earthquakes orders of magnitude greater than terrestrial earthquakes,' said aid Dr Andrew Glikson from The Australian National University (ANU).

'It would have caused huge tsunamis and would have made cliffs crumble.'

1. Wasn't the KT-boundary dinosaur killer "only" 6 miles wide? nt

2. Ya but latest I read was that they now think that the dinosaurs were already

on the cusp of extinction and that the impact was now just one of the many nails in their coffin.
