**Chennai, India (December 21, 2024)** – A new study published in the journal *Nature* suggests the Moon is significantly older than previously believed, potentially forming as far back as 4.51 billion years ago. This challenges the established age of approximately 4.35 billion years, based on the analysis of lunar rock samples.
The research proposes that a major “remelting” event approximately 4.35 billion years ago obscured the Moon’s true age. This remelting, possibly caused by tidal heating from orbital changes, would have erased evidence of earlier impacts and reset the apparent age of many rock samples. The researchers used models to demonstrate the feasibility of such a significant remelting event.
The new findings reconcile discrepancies between previous age estimates and other evidence, such as the number of lunar craters and the age of zircon minerals found on the Moon’s surface. By accounting for this remelting, the study suggests the Moon likely formed between 4.43 and 4.53 billion years ago, aligning better with current understanding of terrestrial planet formation. The older age estimate helps resolve inconsistencies in thermal models and existing geological data.
