Scientists led by Professor Kerry Sieh, from the Earth Observatory of Singapore, are poring over complex data. They’re hunting for the impact crater of a massive meteorite that slammed into the Earth’s surface around 800,000 years ago. Frustratingly, the crater’s location has eluded scientists for over a century. But Sieh and his researchers believe they finally have an answer to this enduring mystery.
Even without a known crater, researchers know that a large meteorite crashed into Earth some 790,000 years ago. And they can say this with confidence because traces left behind by the impact provide concrete evidence. These remnants left from the meteorite’s impact are called tektites.
