New calculations suggest the moon could be a couple hundred million years older than we previously thought!
The Moon Is Probably Older Than We Thought – and Life Could Be Too
“The moon is older than previously thought, pushing back the clock for when conditions on Earth were suitable for life, research published on Wednesday shows. A new analysis of zircon fragments trapped in rock samples retrieved by the Apollo 14 astronauts shows that the moon is 4.51 billion years old, meaning it formed within 60 million years of the birth of the solar system.”
Scientists pinpoint the exact age of the Moon – and it’s older than we thought
“This suggested age makes the Moon a lot older than some recent estimates, which claim our lunar neighbor is 4.3 or 4.4 billion years old. If the results are accurate, it means the giant impact that created the Moon must have occurred fairly early on in the Solar System’s history. The Moon is thought to have formed from the leftover debris of a high-speed collision between Earth and a smaller planet-like object called Theia – and the timing of this event is important for figuring out when life formed here on Earth, too.”
Early formation of the Moon 4.51 billion years ago
“Establishing the age of the Moon is critical to understanding solar system evolution and the formation of rocky planets, including Earth. However, despite its importance, the age of the Moon has never been accurately determined. We present uranium-lead dating of Apollo 14 zircon fragments that yield highly precise, concordant ages, demonstrating that they are robust against postcrystallization isotopic disturbances.”
