Earth’s Oldest Asteroid Crater Found in Western Australia

Geologists have discovered the world’s oldest asteroid crater in the Pilbara Craton, Western Australia, dating back 3.47 billion years. This impact predates the previously confirmed Yarrabubba crater by over a billion years and may have shaped the early Earth's crust and atmosphere. In this blog, we break down how this discovery rewrites the timeline of asteroid impacts — and why it matters for understanding Earth's early evolution.
