Even though these particular lunar craters aren't visible from your backyard, Kring says there are similar, but smaller canyons on the near side of the moon that's visible in the night sky. These ...

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

Vallis Schrödinger is 168 miles (270 kilometers) long and 1.7 miles (2.7 kilometers) deep, and Vallis Planck is 174 miles (280 kilometers) long and 2.2 miles (3.5 kilometers) deep.

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

Vallis Schrödinger and Vallis Planck measure 168 miles (270 km) and 174 miles (280 km) long respectively. On average Vallis Plank is almost a kilometre deeper than the Grand Canyon, as shown in ...

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.

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. Each canyon is over 165 miles long and ...
