"Unearthing Australia's Hidden Giant: The World's Largest Asteroid Impact Structure Discovered"

Researchers have identified what they believe to be the world's largest known impact structure, called the Deniliquin structure, buried deep in southern New South Wales, Australia. Spanning up to 520 kilometers in diameter, it surpasses the previously considered largest impact structure, the Vredefort impact structure in South Africa. The Deniliquin structure shows characteristics of a large impact, such as a central uplifted dome and magnetic patterns indicative of intense magnetic forces during the impact. Further drilling and analysis are needed to confirm the impact and determine its exact age, which could provide insights into Earth's early history.
