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 around two miles deep,

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.

Scientists found that an asteroid impact carved two massive canyons on the moon in minutes. High-speed debris helped shape the trenches.

Two canyons on the far side of the moon, each as large as Earth's Grand Canyon, formed within less than 10 minutes, most likely due to a massive impact there 3.8bn years ago. The object and its work are the subjects of scientific speculation in the journal Nature Communications.
