"Uncovering the World's Largest Buried Asteroid Structure in Australia"

Geologists in Australia have discovered what could be the world's largest asteroid impact structure buried beneath the country, estimated to be over 320 miles in diameter, dwarfing the largest confirmed impact structure. The findings, published in the journal Tectonophysics, suggest that the Deniliquin structure exhibits features expected from a large-scale impact structure, including symmetrical ripples in the crust caused by extreme temperatures. The discovery could have significant implications for our understanding of Earth's geological history.

"Enormous Hidden Meteor Crater Discovered in Australia"

Experts believe that the largest meteor crater on Earth, spanning up to 520km in diameter, is hidden deep beneath the town of Deniliquin in New South Wales, Australia. This crater, believed to be caused by a meteor twice as powerful as the one that wiped out the dinosaurs, is linked to the Late Ordovician extinction event that occurred between 445.2 and 443.8 million years ago. The crater has yet to be tested by drilling, but its existence is supported by geophysical data and magnetic patterns. Further research and drilling are needed to determine the exact age and gather physical evidence of the impact.
