moon It continues to contain mysteries that scientists try to solve. And one of them was fixed, and the pot I was right: What is the nucleus of the only natural satellite of Planet Earth composed of?.
Is that researchers from the University of the Côte d’Azur and France’s Institute of Celestial Mechanics and Ephemeris Calculation (IMCCE) have discovered evidence that coincides with what NASA reported years ago, according to a new study published in the journal Nature.
What is the core of the Moon made up of?
one of the greats scientific doubts passed through the composition of the core of the Moon.
A debate in the first half of the twentieth century spoke of this a rocky world, such as the moons of Mars, Phobos and Deimosor whether it had a different internal geology.
In 2011, NASA planetary scientists obtained clues to solve the million-dollar question.
They resorted to seismic data registered since apollo astronautspredicted what might be at the center of the Moon.
It was then that they speculated that it was likely that, Like Earth, it had a solid inner core.. And the numbers mark an approximate radius of 240 kilometres.
New study on the core of the Moon
The recent study not only appears to confirm that the Moon’s inner core is solid, but also determined its approximate radius and density, it also reports. The viewer.
Scientists have used geological data from the NASA’s Apollo program and GRAIL missionwho used probes to monitor the Moon’s gravitational field for more than a year, to develop a computer model.
From that information, they created a probable profile of the Moon’s interior, with features such as the deformations created due to gravitational interactions with the Earth, as well as the Moon’s distance from Earth and satellite density.
What followed next? To come to a conclusion, they compared a few pre-existing models on the scenarios to see which matched the actual data better.
In this way, they determined that the inner core has a diameter of approx 500 kilometers, only 15% of those possessed by the Moon. Perhaps, they speculate, this small size would explain so much work time.
Density, lunar mantle and other findings
The post showcased another key finding: the density of this nucleus coincides with that of the Earth, something that suggests it would be iron compound. and it comes 7,822 kilograms per cubic meter.
It also warns that its outer core is a fluid layer that covers the inner core and has a radius of 362 kilometers, the research reports.
Another discovery points to a phenomenon called reversal of the lunar mantle, the middle layer between the thin crust and the outer core has shifted a lot.
Meaning it could have caused things like iron-rich material from the core-mantle boundary to rise to the surface, ending in the volcanic rocks that now form the lunar crust.
“Our findings challenge the evolution of the lunar magnetic field thanks to their demonstration of the existence of the inner core,” the study authors wrote.
And they expanded: “Furthermore, they support a global mantle flip scenario that provides substantial insights into the chronology of lunar bombardment in the first billion years of the Solar System.”
