Evidence of moon water found

A new analysis of volcanic glass recovered from the moon decades ago found the rocks contain traces of the constituents of water, challenging a long-held notion that the moon is perfectly dry.

Using a technique that was not available when Apollo astronauts collected the minuscule rocks in the early 1970s, scientists were able to detect telltale signs of water trapped inside the pebble-like glass. Their discovery suggests that water was present deep within the moon when the pebbles were formed during violent lunar eruptions 3.3 billion to 3.6 billion years ago.
