The moon was much older than previously thought. How old is the moon?
On 21 July 1969, mankind made his first steps on the moon. A few hours of stay on the lunar surface, the crew of "Apollo 11" were collected and brought back to Earth more than 20 kilograms of samples of lunar soil. And even half a century later, these samples can still surprise you. For example, recently, scientists from the Institute of Geology and Mineralogy, University of Cologne made a discovery concerning the age of the satellite of our planet. And the Moon was much older than he was before.
How the Moon was formed
For reasons scientists the Moon was formed by a giant collision between a planetary body the size of Mars and ancient Earth. Over time, the Moon rose from the cloud of the substance escaped into Earth's orbit after the collision. The newborn Moon was covered with a magma ocean, which on cooling formed different types of rocks.
How to determine the age of the moon
Scientists from the University of Cologne in their research used the relationship between trace elements hafnium, uranium and tungsten comprising lunah samples in order to understand the rate of melting of these elements. Reaction occurs disintegration of the elements and they decay at different speeds depending on the age of the rock. As long as the breed is older.
Thanks to the unprecedented precision of the measurements, the study has revealed the real age of the moon. Therefore, scientists are no problems by placing the samples in a melting chamber, able to calculate, when the process began, what we now call the lunar samples. Thus I have found out the real age of the moon.
How old is the moon?
Previous studies have indicated that the Moon formed approximately 150 million years after the formation of the Solar system, but thanks to new data, it became known that the Moon is likely to have appeared 100 million years earlier, that is, 50 millionov years after the formation of the Solar system or of 4.51 billion years ago. As stated by scientists, determine the age of the moon is important for understanding how and at what time the Earth formed, and how it developed in the "beginning of his way".
