We all know that dinosaurs likely went extinct when a giant asteroid approximately 10 kilometers (6 miles) across struck the earth 65 million years ago.
What you may not know is that such an asteroid strike was fairly typical in the Earth's early days. According to the estimates of researchers from NASA and collaborators from around the world, between 1.8 and 3.8 billion years ago, the Earth was hit by approximately 70 asteroids of the same or a larger size.
The international team of researchers were able to reach their conclusions by studying ancient rocks in Australia and combining what they learned with advanced computer models.
Dinosaurs, gigantic asteroids, and advanced computing all in one! How could we resist putting the spotlight on this story?
