Researchers from Curtin University, along with collaborators in Australia, report a more precise age for Earth’s oldest known asteroid impact crater. Multiple outlets say the crater—found at or linked to the North Pole Dome region in Australia—dates to roughly 3 billion years ago. The findings are presented as improved dating of an ancient structure preserved in the Australian outback, allowing scientists to better place early meteorite impacts into Earth’s geological timeline. Coverage emphasizes that, while scientific work continues to refine the broader chronology for the site and surrounding rocks, the impact remains the oldest known example identified on Earth. The reporting also links the result to new evidence about how large space rocks shaped the planet during its earliest history, based on geological dating methods described as “detective work” by the research team. Across sources, the main points are that the crater is identified as Earth’s oldest known asteroid impact, and that the best estimate for its age is about three billion years, with researchers highlighting the role of refined dating in improving the record of early bombardment.
