A new study showing the 70km-wide Yarrabubba crater dates impact to 2.29bn years ago. The scientists have discovered the oldest remaining asteroid crater in the world which is the Yarrabubba present in the South Eastern region of Western Australia. The study determines the precise age of the cataclysmic impact to show that it is the same crater to find out the time that it will be triggered to the end of an ancient glacial period warming the entire planet.
