Asteroid crater 520km in diameter buried in southeast Australia, scientists say

New evidence suggests that the world’s largest known asteroid impact structure is buried near the New South Wales town of Deniliquin, according to research conducted by Andrew Glikson and Tony Yeates. The structure, known as the Deniliquin structure, is believed to be up to 520 kilometers in diameter, surpassing the previous record held by the Vredefort impact structure in South Africa. The history of Earth’s bombardment by asteroids is largely concealed due to erosion and burial by sediment. However, recent geophysical discoveries have unearthed signatures of impact structures formed by asteroids, providing new insights into Earth’s early history. Further studies and drilling are needed to gather more physical evidence and determine the exact age of the Deniliquin structure.
