The moon is much older than some scientists believe, a research team now reports. Their precise analysis of zircons bought to Earth by Apollo 14 astronauts reveals the moon is at least 4.51 billion years old and probably formed only about 60 million years after the birth of the solar system -- 40 to 140 million years earlier than recently thought.
