The moon once had active volcanoes when dinosaurs roamed the Earth.

Around 120 million years ago, during the age of dinosaurs, the Moon had active volcanoes.

This recent finding comes from analysis of tiny glass beads collected by China's Chang'e 5 mission, which showed volcanic activity much later than previously thought.

Earlier, scientists believed lunar volcanism ended about 2 billion years ago,

but these beads prove eruptions happened in the early Cretaceous period.

This discovery indicates the Moon retained internal heat to sustain volcanic activity long after it was once assumed to be geologically dead.
