Moon Can be More Younger than Before Thought

To learn more about the birth of the moon, scientists investigated moon rock samples collected during NASA’s Apollo lunar landings and kept at the agency’s Johnson Space Center in Houston. They focused on ferroan anorthosites, which are thought to be the oldest lunar crust rocks. According to study lead author Lars Borg, a planetary scientist at the Lawrence Livermore National Laboratory in California after many years of trying, they  have  found  a  way  to reliably date the ages of lunar crustal with high precision. The scientists discovered these moon rocks apparently crystallized about 4.36 billion years ago, well after the moon is thought to have formed. This means the moon might be either significantly younger than researchers  suspected, or the  prevailing notion of a quickly cooling global ocean of magma might be wrong. Instead, perhaps the lunar crust formed over an extended period of time through the crystallization of small pods of magma, much like the Earth’s crust forms now.
