A team of international researchers from China, the US and Japan has created a computer model that shows that the moon is not totally solid, but shows a layer of liquid that surrounds its core .
In the study, which has been published in the journal Nature Geoscience , experts suggest that this layer of liquid, if it really exists, would have been caused by friction due to Earth's gravity.
In fact, anomalies in the Moon's orbit associated with its gravitational readings have provided clues in this regard. Thanks to the model developed by the researchers, they have concluded that these readings indicate that there is a rotation in the nucleus different from other measurements, which suggests that the Moon's nucleus may be covered by a thin outer layer of liquid . Thus, the computer model took into account the gravity exerted by the Moon, the Earth and the Sun and clearly showed a layer of liquid on the nucleus, with the same measurements that the researchers had obtained on the real Moon.
Why does this layer of liquid exist on the Moon? According to the team of experts, the pull of Earth's gravity causes friction between the lunar core and the material that is just above it, heating it and thus creating this liquid layer.
