These valleys - Vallis Schrödinger and Vallis Planck stretch 270 kilometres (about 168 miles) with depths of 2.7 and 3.5 kilometres respectively.

The discovery centres on the Schrödinger impact basin, where a 1500-mile-wide asteroid struck with energy equivalent to 130 times Earth's current nuclear arsenal.

The discovery demonstrates how a single cosmic collision transformed the lunar landscape in minutes.

This led to the creation of enduring features that help scientists understand the violent events that shaped our cosmic neighborhood.

NASA's Lunar Reconnaissance Orbiter revealed straight-line features radiating from the impact site, showing the path of ejected fragments that were up to 3.2 miles wide.

These canyons hold special significance for NASA's Artemis III mission, which plans missions to the lunar south pole.
