Radiant striae (lunar surface)
Another main feature of the lunar surface is that some relatively "young" craters often have beautiful "radiation patterns". This is a bright band extending in all directions with the craters as radiation points. It almost passes through the mountains, the moon sea and the craters in a straight direction The length and brightness of the radiation text are different, and the most striking thing is Tycho Ring Mountain The longest one is 1800 kilometers long, which is especially spectacular at the full moon. Secondly, the two circular mountains of Copernicus and Kepler also have beautiful radiation patterns. According to statistics, there are 50 circular mountains with radiation patterns The reason for the formation of radiation stripes has not been determined. In fact, it is closely related to the formation theory of craters. Many people are inclined to the meteorite impact theory, and believe that there is no atmosphere and low gravity Moon On the other hand, some scientists believe that the role of volcanoes cannot be ruled out, and the eruption of volcanoes may also form radiative shapes flying around
