Turned out the Moon was 4.51 billion years old

According to scientists, it turns out the moon was older than previously thought, which is 4.51 billion years old. Thus the latest estimates, thanks to the rocks and soil samples collected by the astronauts of Apollo 14 on the moon.
The study has put the age of the Moon at at least 4.51 billion years — up to 140 million years older than previously thought, according to a new study of minerals called zircons brought back from the lunar body to the Earth by the Apollo 14 mission in 1971. (Picture from: http://adf.ly/1iDSow)
A team of researchers reported on Wednesday, January 11, 2017 that the moon formed within 60 million years of the birth of the solar system. The estimates range from 100 million the previous year, then to 200 million years after the creation of the solar system, instead of the 4.6 billion years ago.

Scientists are calculating the age of the moon by using the uranium-lead zircon metal fragments were extracted from samples of moon taken from the Apollo 14 missions. The pieces of zircon was very small, no bigger than a grain of sand.

"Size does not matter, because the fragments record an incredible information!" said the study's lead author Melanie Barboni from the University of California, Los Angeles. She added that the moon has "so many wonders key to understanding how our beautiful Earth formed and evolved."

Some of the eight samples of zircon has been used in a previous study, also conducted at UCLA. Barboni said that she was learning more zircon samples from the Apollo 14, but she expects it will not change the estimated age of the moon is around 4.51 billion year, at most only be 4.52 billion years old.

As we lall knew, the Apollo 14 astronauts, Alan Shepard and Edgar Mitchell collected approximately 41.73 kilograms and uses tubes to dig the ground while exploring the Fra Mauro highlands in February 1971. They walk twice on the moon, as a whole for nine hours on the lunar surface.

And this is the second major study of the moon on this week. Earlier, on Monday, Israeli scientists concluded that the moon may have formed from many mini moons. The moon, according to them, are not formed from the massive giant power hit and release the body parts of the Earth, but from a series of smaller collision may have created many moons eventually merge into one.

This giant force theory says that the result of the blow energy forming the moon lava ocean later becomes solid. This solidification age which is now confirmed by the Barboni and her team.

Barboni said like any process of formation of the moon, the result is the compaction of the moon as it is known today. "We finally determine the minimum age of the formation of the moon, however the process," she said. *** [EKA | FROM VARIOUS SOURCES | SCIENCEDAILY]
