Moon Could Be Much Older Than Previously Believed: New Study Reveals a 4.51 Billion-Year History

Moon Could Be Much Older Than Previously Believed: New Study Reveals a 4.51 Billion-Year History

Breaking News, Learning & Developments, Space
A groundbreaking study published in Nature suggests the Moon may be over 100 million years older than previously thought, dating its formation to approximately 4.51 billion years ago. This challenges the long-standing estimate of 4.35 billion years and offers fresh insights into the Moon's tumultuous early history. For decades, scientists have theorized that the Moon formed after a Mars-sized object collided with early Earth. However, the new study, led by Francis Nimmo of the University of California, Santa Cruz, suggests that the Moon formed earlier, with a later event known as "re-melting" reshaping its surface. This re-melting occurred as the Moon gradually drifted away from Earth. Earth's gravitational pull generated intense tidal heating, resetting the "clocks" of lunar mineral...
