The moon also has a liquid-like core like the Earth

Through analyzing the data obtained from sensors installed on the Moon, scientists from the US Aerospace Agency (NASA) discovered that the Moon also has a liquid-like core like Earth.

The moon has a core in iron-rich solid that is about 240km thick and an outer core of liquid iron about 330km thick. Unlike the Earth, the Moon has a melting boundary around the core, estimated at 480km.

Earlier, from 1969-1972, NASA installed four seismic measuring devices on the lunar surface to record continuous seismic activity on the Moon. This work ended at the end of 1977.

This finding is particularly important, helping the scientific community to learn about the Moon's magnetic field as well as research work around the formation of the Moon.
