The world's oldest remaining asteroid crater is at a place called Yarrabubba, southeast of the town of Meekatharra in Western Australia. Our new study puts a precise age on the cataclysmic impact - showing Yarrabubba is the oldest known crater and dating it at the right time to trigger the end of an ancient glacial period and the warming of the entire planet. Yarrrabubba holds the eroded remnants of a crater 70 kilometres wide that was first described in 2003, based on minerals at the site that showed unique signs of impact. But its true age was not known.We studied tiny "impact-shocked" crystals found at the site, which show the crater formed 2.229 billion years ago (give or take 5 million
