A Giant Asteroid Struck Australia 11 Million Years Ago. So Where Is the Crater?
Uncovering a Hidden Impact: Tektites as Time Capsules A recent study reveals that Australia holds a dramatic record of an ancient asteroid strike, not as a crater, but as tiny pieces of natural glass called tektites scattered across South Australia. The glass fragments are remnants of an event believed to have melted surface rocks and…

11-Million-Year-Old Tektites Reveal Giant Australian Impact
Overview: A Hidden Record of a Giant Impact A remarkable clue to a colossal asteroid strike lies not in a crater, but in tiny glass beads scattered across South Australia. Scientists have identified a new tektite field—a rare natural glass formed when a cosmic object smashes into Earth—telling a dramatic story from about 11 million…
