The Grand Canyon in Arizona is one of Earth's natural wonders, carved out over millions of years by the gradual erosion power of the Colorado River. Close to the moon's south pole are two canyons each comparable in size to the Grand Canyon that were born in a much different process.

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

The vast valleys of Vallis Schrödinger and Vallis Planck demonstrate the incredible forces that shaped the face of the Moon.

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

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.
