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 ...

A wall of Vallis Planck appears to have partially collapsed following the valley’s formation, whereas Vallis Schrödinger has remained more intact.

Unlike the Grand Canyon, which was sculpted gradually over millions of years by the Colorado River, Vallis Schrödinger and Vallis Planck were formed in a matter of minutes. This rapid formation ...

His most recent publication focuses on two immense lunar canyons known as Vallis Schrödinger and Vallis Planck, and draws upon his lifelong experiences with northern Arizona’s most famous ...

Width and depth of the Grand Canyon along the Bright Angel hiking trail from the south to the north rim compared with the width and depth of Vallis Planck, one of the grand canyons on the Moon.

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 ...

Those two canyons—named Vallis Schrödinger and Vallis Planck—are significant clues to that turbulent time in the Moon’s past. And, they’re impressive.

One of the canyons, called Vallis Planck, measures about 174 miles long and 2.2 miles deep. The other, called Vallis Schrödinger, is about 168 miles long and 1.7 miles deep.

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

One of the canyons, called Vallis Planck, measures about 174 miles (280 km) long and 2.2 miles (3.5 km) deep. The other, called Vallis Schrödinger, is about 168 miles (270 km) long and 1.7 miles (2.7 ...

Researches have determined that ejecta from an ancient asteroid. strike carved out the grand canyons (Vallis Schrödinger and Vallis Planck) in less than 10 minutes.
