    Carbon dating of lunar rocks returned from the Apollo Moon missions suggests that the Moon may be 100 million years younger than previously thought.

    Geochemist Richard Carlson of the Carnegie Institution of Washington says that the moon is about 100 million years younger than previously thought.  Even though the moon is our closest neighbor, we still don’t know exactly how or when it formed.  While most scientists are interested in the “how,” Carlson’s intrigued with the “when?” He puts it at 4.4 billion to 4.45 billion years old based on radioactive dating of lunar rocks returned by the Apollo Moon missions.
