The Search for Australia's Hidden Impact Crater

A team of scientists in south Australia have discovered tiny pieces of glass that tell the story of a catastrophic event that happened 11 million years ago, an asteroid impact so massive it should have left a crater the size of a major city, yet mysteriously, no one has found it. This discovery represents only the sixth known tektite field ever identified on Earth. The glassy fragments, scattered across the landscape are forcing scientists to reconsider what they know about ancient asteroid impacts and the geological features they leave behind.
