asteroid.jpgScientists have found evidence of a massive asteroid, 12 to 19 miles (20 to 30km) wide, that struck Earth more than three 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.
