The moon is older than scientists thought, UCLA-led research team reports:
“We have finally pinned down a minimum age for the moon; it’s time we knew its age and now we do,” said Mélanie Barboni, the study’s lead author and a research geochemist in UCLA’s Department of Earth, Planetary and Space Sciences.
The moon was formed by a violent, head-on collision between the early Earth and a “planetary embryo” called Theia, a UCLA-led team of geochemists and colleagues reported in 2016.
The newest research would mean that the moon formed “only” about 60 million years after the birth of the solar system — an important point because it would provide critical information for astronomers and planetary scientists who seek to understand the early evolution of the Earth and our solar system.
