Thanks to human exploration of the Moon bringing some important tools like seismographs to the surface of our natural satellite, scientists discovered lunar earthquakes, and these They revealed a lot about what’s inside the moon.
In the last two decades, that has become clear The moon has a liquid core, but new models show it’s much more than that.
Inside that outer core is a solid inner core similar to our planet.According to a new study published in the journal Nature.
“The Apollo data allowed for a moon with or without an inner core, so the team looked for models that could reproduce the moon’s physical properties from its mass, how it spins and how tides deform it,” it says. in study.
“It gave indications that it was going to be a solid inner core,” he adds. Team evaluates that This inner core is about 310 miles wide. And it is less dense than Earth.
But that’s not the only intriguing insight the model provides. Another is about a phenomenon known as the rolling of the lunar mantle. Simply put, material in the mantle, the thick interlayer between the thin crust and outer core, moved slightly.
Some items including Iron-rich material may have ascended to the surface from the core-mantle boundary, ending in the volcanic rocks that now make up the lunar crust. At the same time, parts of the crust that were denser than others sank through the mantle to the lunar core.
Understanding the inner properties of the Moon today gives us insight into its past.. Scientists believe that the Moon has a magnetic field 100 times stronger than Earth’s.
It was produced by the kernel. The magnetic field is now almost non-existent. Figuring out what the moon’s interior looks like tells us why it might be the way it is, and what might have happened billions of years ago.
“Our results question the evolution of the lunar magnetic field thanks to their demonstration of the existence of an inner core and support a global mantle dipping scenario, which provides substantial information about the chronology of the lunar bombardment during the first billion years of the solar system,” the authors wrote in the study.
