Mega meteorite tore up seabed and boiled Earth's oceans

A huge meteorite first discovered in 2014 caused a tsunami bigger than any in known human history and boiled the oceans, scientists have discovered.

The space rock, which was 200 times the size of the one that wiped out the dinosaurs, smashed into Earth when our planet was in its infancy three billion years ago.

Carrying sledge hammers, scientists hiked to the impact site in South Africa to chisel off chunks of rock to understand the crash.

The team also found evidence that massive asteroid impacts did not bring only destruction to Earth - they helped early life thrive.
