The Moon had volcanic activity much more recently than we knew

China 's Chang'e-5 lander returned small beads that formed from volcanic material to Earth .

They dated the beads to just 125 million years ago.

The Moon is constantly bombarded by particles, and some of these arrive with enough energy to melt.

The composition of these beads can vary wildly, as they're composed of either whatever smashed into the Moon or whatever was on the Moon that got smashed.

In the meantime, the increased exploration of the Moon planned for the next few decades should get us more opportunities to see whether similar materials are widespread on the lunar surface. Eventually, that might potentially allow us to identify an area with higher concentrations of volcanic material than one particle in a thousand..
