Two Grand Canyon-size features on the far side of the moon were likely formed in about 10 minutes after an unknown object slammed into the moon 3.8 billion years ago.

New research shows that when an asteroid slammed into the moon billions of years ago, it carved out a pair of grand canyons on the far side.

The Earth's Grand Canyon took millions of years to carve, but the moon's grand canyons took about ten minutes.

Scientists proposed an explanation for the formation of Vallis Schrödinger and Vallis Planck near the lunar south pole, which are each about the size of Earth’s Grand Canyon.

A colossal impact billions of years ago carved out the canyons that rival the most breathtaking features here on Earth in a matter of minutes,
