The true interest in studying the moon lies in what it can tell us about Earth. As celestial companions with a common origin, the fates of the Earth and moon are tied. But like a wily criminal, the geologically active Earth has a penchant for burying and destroying evidence of past events. The moon is a less deceptive partner—the lack of tectonic activity means that geologic records on the surface last for eons.Futanari Sex Doll

Scientists can look at the lunar evidence to infer what might have also happened on Earth around the same time. For example, in that fateful collision that formed the moon, Earth was rendered uninhabitable—nothing could have survived such a catastrophic event—and all its water could have boiled off, Greer says. If so, then water must have been returned to our planet at some point, perhaps delivered by impacting asteroids, which also would have left clues on the moon.

While the new study dates the completion of the moon’s formation at a minimum of 4.46 billion years, the entire process, from the planetary collision to the eventual hardening, unfolded over millennia. Zircons represent the final vestiges of the lunar magma ocean—the last chapter of the moon’s violent beginnings and the onset of its more placid epoch.Sex Doll Anal

Both Heck and Barboni wouldn’t be surprised if future researchers find an older zircon that produces an even older age for the moon. Perhaps a more ancient crystal lies among NASA’s lunar stash, though Heck says they’re rare. Or maybe more are waiting to be discovered on the moon where humans haven’t yet trodden.

Several missions are in the works to bring lunar samples back from where no one has gone before. In 2024 China will launch a robotic mission that will return samples from the far side of the moon, and NASA’s Artemis III mission aims to land humans on the lunar south pole in December 2025. The new rocks collected at these sites could help refine the story of the moon’s origins.
