Astronomers have found new evidence that the Moon may still be tectonically active. This network of young ridges on the visible side of the moon, which, as scientists believe, is a kind of echo of the cataclysm that gave birth to the pool South pole — Aitken several billion years ago. Article published in the journal Geology.
It is known that the Moon was geologically active several billion years ago, however, there is evidence continuing to this day tectonic activity on the natural satellite of the Earth, which caused a global compression of the subsoil due to the cooling of the moon and tidal forces from the Earth. Seismographs American manned mission “Apollo” in the period from 1969 to 1977 recorded 28 events of seismic vibrations, eight of which could really be generated by the movements of the faults of the growth stress in the lunar crust. In other studies, based on the images from the lunar orbiters, it is shown that observed on the moon in many places narrow ridges and ledges, crossing a small crater, talking about the tectonic processes that occurred less than a hundred million years ago.
Valentines Adomas (Adomas Valantinas) from the University of Bern and Peter Schultz (Peter Schultz) from brown University, looking at the moon region-free regolith, using images taken with the camera NAC orbital probe Lunar Reconnaissance Orbiter, as well as using data on the temperature of the surface of the satellite, obtained by the on-Board radiometer Diviner. They found more than five hundred areas with exposed bedrock ridges and narrow (about thirty feet) ledges and grabens. The absence of small craters in these areas speaks to the young in geological plan areas (less than ten million years), which are formed faster than it is destroyed as a result of meteoritic bombardment. Many of these systems ridges are far beyond Masanov in the lunar seas and are not affiliated with any global tectonic pattern.
