Approximately how old are the glass beads discovered in the Chang'e 5 samples?
Answer
120 million years
Analysis of the glass beads recovered from the lunar soil revealed an age of approximately 120 million years. This date places the volcanic activity in a much more recent timeframe than the long-held consensus that the Moon had ceased all volcanic engine activity between two to three billion years ago. This discovery implies that the internal heat of the Moon persisted much longer than models previously allowed.
