The canyons studied, Vallis Schrödinger and Vallis Planck, are comparable to the Earth's Grand Canyon in size.

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

It didn’t take long for the moon to get its grand canyons. Vallis Schrödinger and Vallis Planck are two long channels near the lunar south pole. The canyons, each more than 160 miles long and ...

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.

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.

The two canyons, called Vallis Schrödinger and Vallis Planck, are located on the far side of the moon, so they can only be seen from orbit—not from Earth.

A tale of two canyons A comparison of the width and depth of the Grand Canyon along the Bright Angel hiking trail (top) and Vallis Planck on the moon’s south pole (bottom).

The lunar canyons Vallis Schrödinger and Vallis Planck are extraordinarily deep, and scientists now know the valleys were carved by bullet-fast moon rocks.

Scientists say Vallis Schrödinger and Vallis Planck—dramatic trenches near the lunar south pole—were carved in a blast that unleashed 130 times the amount of energy in Earth's global nuclear ...

Lunar geologists have always known that the two canyons featured in the new study, called Vallis Schrödinger and Vallis Planck, were particularly large.

The canyons studied, Vallis Schrödinger and Vallis Planck, are comparable to the Earth's Grand Canyon in size.
