"Newly discovered moon rock reveals surprising age discrepancy"
TL;DR Summary
Zircon crystals found in a rock collected by Apollo 17 astronaut Harrison Schmitt in 1972 have provided scientists with new insights into the moon's formation and its age. Using a method called atom probe tomography, researchers confirmed that the moon formed more than 4.46 billion years ago, about 40 million years earlier than previously believed. The crystals, which formed after a giant impact between Earth and a Mars-sized object called Theia, help shed light on the moon's role in stabilizing Earth's axis and its significance for future space exploration.
