The Moon’s rotation axis changed by 6 degrees

Recent studies researchers indicate that the axis of rotation of the moon has not changed as much as previously thought. Using the data collected by the Lunar Prospector in the late 1990, NASA scientists saw on the Moon two regions rich in hydrogen. They are located near the poles of the satellite, possibly indicating the presence of ice.

Ice are facing each other and the boundary between them passes through the center of the Moon is erstwhile spin axis. Number indicates that the axis around which the moon rotates has shifted about 6 degrees.

The cause of this phenomenon was probably volcanic activity in the region known as Oceanus Procellarum. It is precisely this area covers most of the dark spots of the Moon, which are visible from the ground.

The Region of Oceanus Procellarum was the most geologically active area of the Moon, which means that the movement of ice covers has been initialized billions of years ago, “said Matt Siegler, one of the authors of the new study.
