Africa-Press – Namibia. <\/strong><\/span>While it was initially assumed that the protoplanet Theia had struck the proto-Earth with a glancing blow in the event that formed the moon, recent studies have found that a direct impact would not have necessarily destroyed both planets.<\/p>\n

She doesn\u2019t look a day over 4.51 billion years old!<\/p>\n

A new study of how Earth\u2019s moon formed has found that the natural satellite is actually 40 million years older than previously believed, putting its formation at 4.52 billion years ago.<\/p>\n

The new age was determined by studying ancient crystals found in the rocks retrieved from the lunar surface by the Apollo 17 mission, the last time humans walked on the moon, in 1973. Called zircon, the gemstone is formed when the elements zirconium, silicon, and oxygen crystallize in magma, or liquefied rock.<\/p>\n

Zircon is a useful crystal for dating rock samples because it contains a certain amount of the radioactive elements uranium and thorium, which can be used to tell when the crystal first formed based on how much of them has undergone radioactive decay into smaller elements. The scientists used this method to find out when the zircon crystals formed and got a shocking number: 4.52 billion years ago, about 40 million years earlier than the previous estimated age of 4.46 billion years old.<\/p>\n

“It’s amazing being able to have proof that the rock you’re holding is the oldest bit of the moon we’ve found so far,” study lead author Jennika Greer, a research associate at the University of Glasgow, told US media. “It’s an anchor point for so many questions about the Earth. When you know how old something is, you can better understand what has happened to it in its history.”<\/p>\n

According to the prevailing theory about the moon\u2019s formation, early in the solar system\u2019s formation, Earth was struck by a smaller planet about the size of Mars, which turned both planets molten and blew out a huge amount of rock, some of which fell back on Earth but some of which remained in orbit around the Earth, coalescing into the moon. This explains why unlike almost any other moon in the solar system, ours looks like a planet on the inside, bearing almost the same composition and structure as the Earth.<\/p>\n

\u201cIt moves the goal post. It pushes back the minimum age of the moon formation,\u201d Greer added. \u201cIt\u2019s important to point out, this is the oldest age to date. It doesn\u2019t mean we now know the age of the moon and we should stop looking.\u201d<\/p>\n
