NASA spacecraft has found signs of geological activity on the Moon. The device Lunar Reconnaissance Orbiter (LRO) has transferred the image is converted as the moon's surface, forming a small valley on its sites.

Scientists suggest that this geologic activity occurred less than 50 million years ago — nothing at all on a cosmological standards, considering her age, which is more than 4.5 billion years.

A team of astronomers at NASA during the analysis of high resolution drew attention to the specific trench, pointing to gaps of the lunar crust. These linear valleys known as Grabens are formed on the surface by stretching and breaking the crust planet or another celestial body. Several relatively fresh grabens were found over the entire surface of the moon.

The researchers suggested that the moon is being shrunk due to cooling is still hot core. Thus, the grabens are a kind of "measuring instrument", which measures the force of contraction. According to specialists, the compressive force of the moon is low, which means that, unlike the terrestrial planets, the Moon is not completely melted in the early days of its formation. Most likely, it was only covered by oceans of molten rock.

Grabens were an unexpected discovery for scientists. They show that the moon was still geologically active and requires rethinking some ideas about the satellite of our planet. Scientists will continue to monitor the grabens and will monitor their growth in order to create a detailed model of the behavior of the moon.
