Scientists say they have discovered water trapped inside tiny beads of glass scattered across the moon, suggesting a potential reservoir of this precious resource for future human activities on the lunar surface.

The moon was long believed to be dry, but over the last few decades, several missions have shown there is water both on the surface and trapped inside minerals.
