Scientists have found what might be the world's largest asteroid impact structure buried deep in southern New South Wales, Australia. This huge Deniliquin structure is a whopping 520 kilometers in diameter, possibly beating the previous record held by South Africa's 300-kilometer-wide Vredefort structure. Can you imagine the chaos when that asteroid hit Earth? Let's dive into this discovery and explore what could have happened during that colossal impact. It's mind-blowing to think about!
