The moon was much older than previously thought
Source:On 21 July 1969, mankind made their own . A few hours of stay on the lunar surface, the crew «Apollo 11» gathered and brought to the Ground 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 of scientists, the result of a gigantic 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.
These rocks «recorded» information about the formation of the moon, and they still can be found on the lunar surface — says Dr. Maxwell Thiemens, researcher, University of Cologne and lead author of the study. Such observations are no longer possible on Earth, since our planet was geologically active for a long time, and in that condition, and gives us a unique opportunity to study planetary evolution.
a Lonnie samples, which made it possible to calculate the actual age of the moon
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. The longer — the breed is older.

Thanks to unprecedented measurement accuracy, the study 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 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 was formed and how it developed in the «the road».
