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 ...

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

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.

Scientists analyzed the lunar canyons, named Vallis Schrödinger and Vallis Planck, to find that these huge valleys measure 167 miles long (270 kilometers) and nearly 1.7 miles (2.7 km) deep, and ...

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 ...

By Ashley Strickland, CNN (CNN) — About 3.8 billion years ago, two massive canyons likely formed on the moon in a span of less than 10 minutes, ...

The Earth's Grand Canyon took millions of years to carve, but the moon's grand canyons took about ten minutes.

By Ashley Strickland, CNN (CNN) — About 3.8 billion years ago, two massive canyons likely formed on the moon in a span of less than 10 minutes, according to new research. The extraordinary ...
