Hidden in the dust: The 2-billion-year-old asteroid crater that holds the secret clue to ending an ice age

Scientists have identified the Yarrabubba impact crater in Western Australia as the Earth’s oldest, dating back 2.229 billion years. This ancient collision, occurring when Earth was covered in ice, may have released massive amounts of water vapour, potentially ending a global ice age. The discovery offers crucial insights into early Earth’s climate history.
