It's right there: Nasa discovers water on Moon's crater visible from Earth

The discovery comes on the back of several other observations made in the past, including by Chandrayaan-1. Here's why it is of critical importance

In one of the biggest astronomical discoveries of the decade, Nasa confirmed the presence of water on the sunlit surface of the Moon. The Stratospheric Observatory for Infrared Astronomy (SOFIA), for the first time, confirmed that water may be distributed across the moon and not just limited to cold, shadowed places. The water molecules were found on Moon's Clavius Crater, one of the largest craters visible from Earth.

Scientists believe that the majority of the water detected must be stored within glasses or in voids between grains sheltered from the harsh environment, allowing the water to remain on the lunar
