The Yarrabubba impact structure in Western Australia is caused by Earth’s oldest known asteroid strike – and it may have ended an ice age over 2.2 billion years ago ☄️⠀ ⠀ The tiny town of Meekatharra, about 750km north-east of Perth, doesn’t have many claims to fame. But just outside this mining town is the world’s oldest remaining asteroid crater, say scientists.⠀ ⠀ The 70-kilometre wide Yarrabubba crater, on Tjupany traditional land, was first discovered in 2003. Now, researchers have put a precise date on the cataclysmic impact that created the crater, and it’s a phenomenal 2.229 billion years old.⠀ ⠀ At over 2.2 billion years old, it’s age puts it at the the end of an ancient deep freeze known as early Snowball Earth, and the researchers believe the strike could have contributed to the ice thawing.⠀ ⠀ Read more via the link in our profile! ⤴️ ⠀ ⠀
