The LRO device photographed an unusual lunar formation

The presented image was made by the LRO. On it you can see an unusual crater-like formation on the visible side of the moon. It was discovered in 1971 by the Apollo 15 expedition. After 8 years, the International Astronomical Union assigned the formation the name Ina.

The formation is small in size. Its diameter is about 3 km. It is assumed that its origin is associated with the consequences of volcanic activity. According to one version, Ina was formed as a result of gas breakthroughs, which scattered rocks on the surface and exposed a layer of rocks under them. According to another, it arose as a result of the collapse of the ancient lava tube.

Another mystery of Ina is her age. Many experts believe that it does not exceed 100 million years. This opinion is based on a relatively small number of craters on the surface of Ina. According to the alternative point of view, everything is exactly the opposite.Ina was formed about 3.5 billion years ago, and the lack of craters is associated with the special properties of this surface area.
Ina's photographs also serve as an example of a well-known optical illusion, when in photographs of celestial bodies it seems that craters are convex portions, and elevated portions, on the contrary, are located below. It arises due to the peculiarities of the perception of images by the human brain. We are used to the fact that the default light falls from above and to the left. Therefore, objects whose upper part is illuminated and the lower part is in the shade are perceived as elevations. One of the easiest ways to get rid of this illusion is to flip the image.
