Oldest Crater
When we gaze out into our solar system and observe its several planets and many moons, one thing tends to be true of just about all of them: They have lots and lots of impact craters. Each of those scars on a planet or moon’s surface tells a story, and while Earth’s weather and plentiful water ensure that most impact craters are erased or obscured from view, there are still a number of them that researchers have been able to sniff out.
As NASA reveals in a new post on its website, the previous record holder for the oldest crater on Earth has been bested by a new discovery in Australia. Called the Yarrabubba meteor crater, it’s estimated to be a whopping 2.229 billion years old.
