In a groundbreaking discovery, researchers have unearthed a mysterious variety of natural glass, known as tektites, scattered across parts of South Australia. These rare, ancient glasses hold secrets to a long-forgotten event in Earth's history - a colossal asteroid impact that left an indelible mark on the planet.
The tektites, formed when a meteorite struck Earth with immense force, melted the surface and flung molten material across vast distances. According to Professor Fred Jourdan from Curtin's School of Earth and Planetary Sciences, these tiny pieces of glass are like "little time capsules from deep in our planet's history." The discovery, led by PhD student Anna Musolino from Aix-Marseille University, reveals that these tektites boast an unusual chemistry and an age of approximately 11 million years, setting them apart from all previously known tektites.
What's even more astonishing is that despite the impact's enormous magnitude, scientists have yet to locate the crater. This enigmatic event has sparked a flurry of interest, as understanding the frequency and timing of large asteroid impacts is crucial for assessing the risk of future collisions, a vital aspect of planetary defense.
