New research confirms the Silverpit Crater in the North Sea was formed by an asteroid impact around 43 million years ago. Using seismic imaging and rare mineral evidence, scientists proved the impact origin beyond doubt, resolving a debate that lasted two decades and placing the crater among Earth’s rare, well-preserved impact structures.New research confirms the Silverpit Crater in the North Sea was formed by an asteroid impact around 43 million years ago.
