Asteroid impact on moon blasted two grand canyons in 10 minutes
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.
How an Asteroid Hit the Moon and Made Two 'Grand Canyons'
Two immense canyons on the moon's far side that rival Earth's Grand Canyon were produced by a cataclysmic collision nearly four billion years ago, according to new research published on Tuesday. According to the findings,

Two of the Moon’s Grand Canyons Were Formed in Just Ten Violent Minutes, New Study Suggests
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 weapons i
Massive lunar canyons formed within minutes, most likely due to asteroid strike
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.
Asteroid impact carved massive canyons on the moon in minutes
Scientists found that an asteroid impact carved two massive canyons on the moon in minutes. High-speed debris helped shape the trenches.
